3 1.0 Introduction Increasingly stringent environmental best management practice requires planners and developers to apply a fit-for-purpose treatment train approach to stormwater treatment to achieve today s water quality objectives (WQO's). To respond, in consultation with its industry partners developed an innovative treatment solution the Cartridge Filter. The Cartridge Filter addresses a gap in the stormwater treatment technology market. All current stormwater treatment cartridge systems remove particulate bound contaminants but fail to remove the colloidal and dissolved load, especially in the case of nutrients and heavy metals. The Cartridge Filter is designed to economically filter particulate bound contaminants, oil and grease as well as dissolved contaminants (inclusive of heavy metals and nutrients such as nitrogen and phosphorous) to meet stringent water quality targets. The system has been designed to carry out multiple treatment processes on stormwater runoff within the one compact underground device. In particular it is designed to remove, at pre-determined treatable flows, particulate, dissolved and in some cases colloidally bound contaminants such as: suspended solids; heavy metals; oil & grease; hydrocarbons; nitrogen; and phosphorous. In developing this innovative stormwater treatment system careful consideration has been given to durability, longevity, cost, and maintainability. Key commercial technical features include: widely available chemically conditioned filter medias; a system capable of achieving low pollutant discharge levels; low visual impact and energy footprint; designed hydraulics with proven performance and longevity; scalable design; and cost effective maintenance regime. This technical manual describes the operation and performance characteristics of the system. Page 2

4 1.1 How the Cartridge Filter Works Two distinctive systems are available as compact, total treatment train systems incorporating primary, secondary and tertiary treatment within the one underground device. The first (the ECF At- Source System) is designed specifically for at-source treatment of stormwater pollutants and the second (the ECF Offline series) is designed for treatment typically of the 1 in 3 month to 1 in 1 year ARI stormwater flows. 1.2 The At-Source Cartridge Filter The ECF At-Source system is designed specifically for field inlet applications. Ideally suited on smaller catchments such as commercial car parks applications with inlet flows ranging from L/s, it provides a compact cost efficient at-source treatment solution specifically targeting suspended solids, heavy metals, total phosphorous and nitrogen including free floating oils and grease. Housed in a pre-cast concrete chamber, it consists of a primary treatment inlet litter basket designed to capture and retain all particles larger than 200 micron, then incorporates series of internal baffles for retention of hydrocarbons in a spill situation and the retention of particles larger than 93 micron then includes the unique patented StormDMT multi barrier cartridge filter for tertiary treatment. Page 3

5 1.3 The Off-Line Cartridge Filter Series This unique cartridge filter series is designed to remove particulate dissolved and colloidally bound contaminants from stormwater flows using a multi chamber system and incorporates the unique, patented multi barrier StormDMT cartridge filter. The system consists of an underground pre-cast concrete chamber that houses the individual cartridges. The system is unique in that it also includes a primary treatment litter basket, hydrocarbon retention baffle and fore bay chamber onsisting of a baffle system to provide detention and settling of sedimentation prior to flows entering the cartridge filter chamber for further tertiary treatment. This system is ideally suited to medium to larger catchments with inlet flows ranging from 19 88L/s depending on the number of cartridges. In essence the system provides a complete treatment train approach within one compact underground tank incorporating the following elements: Primary Treatment During a storm event, runoff conveying pollutants is diverted (off-line) to the Cartridge Filter where gross litter is pre-screened and retained within the primary treatment litter basket. The primary treatment chamber consists of a removable stainless steel 304 grade litter basket lined with a 200 micron media. It is designed specifically to capture and retain in a dry state all pollutants larger than 200 micron. Secondary Treatment Flows are then diverted under a baffle in the fore bay chamber. Within this chamber solid particulates will settle out and any free floating oils and grease will attach to the removable perforated stainless steel baffle which consists of a hydrocarbon filter media. This media has been specifically designed to absorb and retain hydrocarbons within its unique structure. Additionally oil separator alarm devices can also be fitted to achieve class 1 separator compliance. Page 4

6 1.3 The Off-Line Cartridge Filter Series continued Tertiary Treatment The pre-treated stormwater then flows through a series of flow dissipating baffles into the tertiary treatment chamber. The pre-treatment of incoming stormwater flows, significantly enhances the performance and operational life of the cartridge filter as only fraction of finer particles <93 micron and dissolved pollutants are released into the tertiary treatment chamber at predetermined flows. The pre-treated stormwater runoff cross flows through the cartridge filter media into the central perforated pipe where flows are then diverted to an underfloor pipe and discharged into an outlet chamber within the unit. The StormDMT cartridge(s) comprises of the following three filtration medias. Porous Polypropylene designed to remove fine solids, oil & grease, and particulate bound contaminants aiming to protect and increase the lifespan and performance of the downstream filter media; Chemically conditioned Clinoptilolite is designed to remove mainly positively charged dissolved contaminants and in some cases colloidally bound contaminants. In particular heavy metals such as mercury, cadmium, chromium, nickel, zinc, copper, lead and nutrients such as ammonium nitrogen; Laterite is designed to remove negatively charged dissolved contaminants. In particular heavy metals such as arsenic and nutrients such as nitrate nitrogen and phosphate. In addition this layer functions as a final polishing step to achieve stringent discharged limits in regard to heavy metal concentrations. The StormDMT cartridge addresses a gap in the stormwater treatment technology market. All current stormwater treatment cartridge systems remove particulate bound contaminants but fail to successfully remove the colloidal and dissolved load, inclusive of nutrients and heavy metals. One of the great advantages of the StormDMT cartridge is its flexibility. A tailored cartridge arrangement with specific layer characteristics can be provided to accommodate site specific requirements. For example, if there is a need to target the removal of copper, zinc and/or lead then the Clinoptilolite layer can be designed thicker than the other two layers. Alternatively, if arsenic or phosphorous is a key focus then a thicker Laterite layer can be incorporated. This tailored solution achieves higher performance and ensures longer cartridge operational life. Page 5

7 2.0 StormDMT Cartridge Filter Credentials & Case Studies The StormDMT multi-barrier cartridge filter as well as its three specific filter materials has been trialled in water, wastewater, and stormwater treatment applications around the world. The results obtained have been published in peer review journals and international conference proceeding s. This section summarises the findings of these studies. Otsu, Shiga-Japan Trial A stormwater treatment device packed with Porous Polypropylene media was trialled in Otsu, Shiga-Japan along the roadway of route 165 between October 2000 and January 2001 (Saburo Matsui et al., 2003). Eight rainfall events were monitored with the total rainfall and maximum intensity ranging from 7 mm to 51mm and from 2mm/hr to 10mm/hr, respectively. The mean removal efficiency for pollutants studied was 92.3% for Total Suspended Solids (TSS), 71.9% for Chemical Oxygen Demand (COD), and 43.6% for Total Phosphorous (TP) and above 70% and 60% for the heavy metals and Polycyclic Hydrocarbons (PAHs), respectively Wastewater Trials Clinoptilolite s high selectivity for NH4-N is very well known in municipal and agricultural wastewater treatment. Examples of the application of Clinoptilolite in wastewater include: A 27 ML/d capacity plant at Lake Tahoe, California, used several hundred tonnes of Clinoptilolite from the Hector deposit (Butterfield and Borgending ), Wastewater plants with capacities of 45 and 245 ML/d in Virginia, USA (Gunn 1979). Pig farm wastewater with 10,000 pigs (150 m3/d) was treated in a cascade multistep system using mechanical, chemical, and biological processes (Zubaly et al., 1991). Large suspended particles were first removed by grating the sewage. Suspended particles, colloids and dissolved organic and inorganic species not removed by the grate were then passed through a channel (six 20 m sections separated by barrages). Approximately 20 m3 of Clinoptilolite from the Tokaj Hills deposit in Hungary were placed in each section. The Clinoptilolite filter removed 100% of oils and fats, 98% of suspended solids and 95% of dissolved organic and inorganic impurities from the wastewater. The Clinoptilolite filters successively removed these impurities for two years. The exhausted Clinoptilolite was then used as a fertiliser. Several studies that illustrate the effective use of Clinoptilolite for the removal of NH4-N have been published in the last 20 years (Hankins et al., 2004; Sprynskyy et al., 2005; Aiyuk et al., 2004). Page 6

8 2.0 StormDMT Cartridge Filter Credentials & Case Studies continued Clinoptilolite has been used as a natural ion exchanger for the removal of radioactive cations such as Cs+ and Sr2+ and heavy metal cations such as Cu2+, Cd2+, Zn2+, Ni2+, Pb2+, Hg2+, Cr3+, and Mn2+. Examples of full scale applications using zeolites such as Clinoptilolite for the removal of Cs+ and Sr2+ from radioactive wastes are (Mercer and Ames, 1978): Hanford Nuclear Lab., Washington, USA; Idaho National Engineering Laboratory, Idaho, USA; Savannah River Plant, Aiken, South Carolina, USA; and British Nuclear Fuels, Sellafield, USA. University of Munich Trial A Clinoptilolite cartridge filter was trialled in Garching campus of the Technical University of Munich, in Germany treating the runoff from an eleven years old zinc roof (Athanasiadis et al., 2004). Samples of 24 rain events were examined and zinc was detected in the roof runoff in concentrations up to 25 mg/l, and lead which originated from the tin-solder was present in concentrations up to 84 µg/l. The Clinoptilolite filter was able to remove up to 97% of zinc from the roof runoff. Academy of Fine Arts, Munich Trial A technical infiltration system equipped with Clinoptilolite as an artificial barrier material for the treatment of copper roof runoff was installed and monitored in the Academy of Fine Arts in Munich, Germany (Athanaiadis et al., 2007). During the 2yr sampling period, 30 rain events were examined. The technical infiltration system was able to reduce the copper concentration from the roof runoff by a factor up to 96% Port of Townsville Trial Finally, a full scale pilot trial of the StormDMT multi-barrier cartridge filter was undertaken at a bulk storage facility in the Port of Townsville handling the following chemicals (Athanasiadis, et al., 2014): Magnetite concentrate; Copper concentrate; and Zinc concentrate. The aim of the pilot trial study was to evaluate the performance of the StormDMT technology, a low cost passive multi barrier treatment system, for the treatment of the stormwater runoff generated onsite. Factors such as hydraulics (0 to 100 l/s) stormwater runoff quality, and metal speciation (particulate, dissolved and colloidal) were investigated. StormDMT metal removal efficiency for zinc mass was 90%, Copper 85% and lead 80%. Metal concentrations at the outlet of the StormDMT filter were always lower than the regulated site discharged limits. Considering the site relevant stormwater runoff rates of copper, zinc and lead, the StormDMT technology demonstrated a minimum maintenance life of two years. Page 7

9 2.0 StormDMT Cartridge Filter Credentials & Case Studies continued University of Adelaide Trial has always sought pro-actively to validate all its products performance through extensive independent laboratory and field testing. In May 2014 commissioned EngTest the commercial arm of the University of Adelaide, Sim Physics Pty Ltd and GHD to undertake additional laboratory and desktop modelling to further confirm the products performance. Several additional field pilot sites are currently being established with additional product performance technical reports to be peer reviewed and published in late Warranty and Life Expectancy The Cartridge Filter has a one-year warranty covering all components and workmanship. will rectify any defects that fall within the warranty period. The warranty does not cover damage caused by vandalism and may be invalidated by inappropriate cleaning procedures or where the unit is not cleaned with the recommended frequency. The stainless-steel primary treatment litter basket, removable hydrocarbon baffle and cartridge filters have a life expectancy of 20 years and the pre-cast concrete pit has an estimated 50-year life span. Page 8

10 4.0 Safety and Considerations The simple, yet effective design of the Cartridge Filter reduces OH&S risks as most of the work is undertaken in a controlled factory environment. The unit arrives to site complete and ready for installation reducing significantly on-site time, an important factor given the costs associated with delays that can be caused by inclement weather. The lockable access lids reduce the likelihood of vandalism and are easily removed by hand using readily-available lifters. 5.0 Environmental Impact is accredited to ISO 14001:2004 (Environment) and undertakes all manufacturing and construction within the requirements of this Standard. Hence, its carbon impact is limited and as the Cartridge Filter is housed in a pre-cast pit and is usually located underground it has little or no impact on the environment with the access lids designed to blend in with the surrounds of the site. Page 9

11 6.0 Key Features and Benefits The Cartridge Filter is a fully self-contained modular system supplied to site ready to install thereby reducing onsite construction lead-times and disruption to the general public. Two distinctive systems are available, the first (the ECF At-Source Cartridge Filter System), designed specifically for at-source treatment, the second (the ECF Off- Line series), designed as a compact total treatment train system incorporating primary, secondary and tertiary treatment within the one underground device. The Cartridge Filter has many features and benefits, some of which are listed below: Key Features Hydraulics Pollutant Capture and Reten on Benefits Design incorporates an off-line high flow by-pass 100% treatable flow rate (TFR) Provides primary, secondary and tertiary treatment within the one device.

17 8.0 Collection and Removal Efficiencies In recent years modern Water Sensitive Urban Design (WSUD) objectives and principles now applied to most urban development s require more onerous water quality objectives (WQO's) specifically targeting the removal of suspended solids, nitrogen, phosphorus and heavy metals. The Cartridge Filter is designed to carry out multiple treatment processes of stormwater within the one compact modular system. Primarily designed to remove solids, colloidal bound and dissolved contaminants it can play an integral role in reducing pollution in heavily-urbanised catchments that discharge to our waterways. Contaminant/Pollutant Es mated Mean Pollutant Removal Efficiency Primary & Secondary Treatment Chambers¹ Gross Pollutants >3000μm Total Suspended Solids μm 99% 98% TPH & Oil and Grease (mg/l) 95% Ter ary Treatment Chamber Total Suspended Solids (mg/l) reduc on 92% Total Nitrogen² % Total Phosphorous² % Ammonium Nitrogen² 99% Arsenic³ 60-97% Cadmium⁴ 97% Pollutant removal efficiencies are based on typical urban catchment m ea n pollutant concentrations.

18 9.0 Music Modelling Guidelines These guidelines provide instruction to the creation and application of a treatment node for the Off-Line and At- Source Cartridge Filters for the Model for Urban Stormwater Improvement Conceptualisation (MUSIC). The Cartridge Filter can be modelled in MUSIC using the Generic Treatment n o d e t o represent the results derived from independent laboratory testing and field testing by the University of Munich, GHD and the University of Adelaide (ENGTEST The school of civil, environmental and mining engineering). The guidelines apply to the creation of the treatment node within MUSIC v Product Performance The Cartridge Filter brings together technology from around the world in way which suits Australian conditions, the outer layer of Porous Polypropylene has been studied in Japan with effective removal rates of Hydrocarbons and Total Suspended Solids, Clinoptilolite has had many studies in Germany and the USA into its removal of heavy metal cations as well as positively charged nutrient ions such as Ammonia (Nitrogen) and Laterite effectively removes negatively charged ions such as nitrites, and Phosphates in water flows. The StormDMT project bought these elements together and GHD performed a field study at the Port of Townsville into the treatment levels of the total system. We are continuing further pilot site programs in conjunction with a range of institutions and should be able to add to the body of testing data over the next few years. Page 17

19 9.2 Creating the Node Insert a Generic Treatment node into your model by selecting Generic under the treatment nodes menu. When the node is created the node properties dialog is displayed. There are several changes that need to be made in this dialog. The transfer function for each pollutant in the node can then be defined to meet the input and output values that reflect the capture efficiencies (CE) of the Cartridge Filter (Table 1) up to the design TFR. It is important to select the appropriate Treatable Flow Rate. To change the Treatable Flow Rate adjust the high flow bypass to the flow the unit can treat detailed in Table 2 (e.g. 10L/s = 0.010m3 as the high flow by-pass). An representative can assist you in selecting the most appropriately sized unit for your next project.

20 10.0 Design Guidelines To ensure your system is appropriately designed for its intended application and meets local water quality objectives it is essential that the following minimum information is provided: Confirm the required treatable flow rate this is the minimum stormwater run-off volume that must be treated. Typically this is the 1 in 3 month to 1 in 1 year ARI; Confirm the proposed location of the unit relevant to other stormwater controls and overall drainage design. It is also important we know the catchment size including percentage of impervious area and hydrology; Confirm local water quality objectives - Recent state governmental planning policies have established clear stormwater quality bench mark objectives for local and regional councils. Accordingly local and regional council water sensitive urban design objectives have been amended to meet these stormwater pollution reduction targets. It is important we are provided this information specific to your site and local council regulations; and Confirm sediment loads, composition and concentrations of target pollutants generated from the site. This may vary significantly from one site to the next depending on the land use. This data is essential as it allows to appropriately size and configure your unit specific to its application. Should this information not be available then typical urban roads mean pollutant concentration levels will be assumed specific to the catchment type and land use. For further assistance in sizing or specifying a system for your next project please complete the form in Appendix 2 and forward to your local representative. Page 19

21 m³ 11.0 Hydraulic Specification Treatable Flow Rate (TFR) is defined as the maximum flow rate through the Cartridge Filter before the flow overtops the upstream by-pass overflow weir. TFR is constrained by the infiltration capacity (Hydraulic Conductivity) of the engineered StormDMT cartridge(s). The total flow rate treated by the Cartridge Filter is determined by the number and size of cartridges installed. Standard systems are available or can custom design and build a system specific to your site requirements. The indicative catchment areas indicated in the table below are based on a 50% fraction impervious catchment and Melbourne climatic dataset.

Additionally, media densities can be tailored to specifically cater for target pollutant concentrations. For indicative catchment areas relevant to your location please refer to appndix 1. Page 20

22 m³ 12.0 Cleaning and Maintenance As with all filtration systems, the Cartridge Filter should be cleaned regularly. The cleaning frequency, and the cost, depends heavily on the surrounding environment, the unit s proximity to a waste facility and the concentration and volume of pollution conveyed to the system. However regardless of the system configuration the media requires exchange or regeneration. This is essential in maintaining its operational efficiency. The figures below give a broad guideline about the number of cleans required annually for each treatment element within the individual Cartridge Filter system. product code Primary Treatment Chamber Li er Basket Fore-bay sediment & free floa ng hydrocarbon chamber Secondary Treatment Chamber Fore-bay removable hydrocarbon baffle Ter ary Treatment Chamber StomDMT Cartridge(s) ECF At-Source 6 cleans per annum or immediately a er a major rain event 6 cleans per annum or immediately a er a major rain event Every 12 months replacement of the filter media is recommended or immediately a er an oil spill 12 monthly cleaning and replacement of the filter media is recommended ECF Single 4 cleans annually or immediately a er a major rain event 4 cleans annually or immediately a er a major rain event Every 12 months replacement of the filter media is recommended or immediately a er an oil spill Every months replacement of the filter media is recommended ECF Double 4 cleans annually or immediately a er a major rain event 4 cleans annually or immediately a er a major rain event Every 12 months replacement of the filter media is recommended or immediately a er an oil spill Every months replacement of the filter media is recommended ECF Triple 4 cleans annually or immediately a er a major rain event 4 cleans annually or immediately a er a major rain event Every 12 months replacement of the filter media is recommended or immediately a er an oil spill Every months replacement of the filter media is recommended ECF Quadruple 4 cleans annually or immediately a er a major rain event 4 cleans annually or immediately a er a major rain even Every 12 replacement of the filter media is recommended or immediately a er an oil spill Every months replacement of the filter media is recommended Page 21

23 12.1 Monitoring Under normal weather and operating conditions, your Cartridge Filter should be checked a minimum of every two - three months depending on the quality and quantity of the inflow to the unit. Initially, recommends that monitoring is undertaken monthly. Once the unit has been in operation for an extended period of time (say, 24 months) then the monitoring schedule can be adjusted to reflect the actual operating conditions specific to the catchment. Under normal operating conditions the Primary Treatment Basket and Sediment Chamber would normally require cleaning approximately every 3 months Cleaning and Maintenance Procedures During the first two years of operation it is important to regularly monitor and maintain the system to ensure adequate ponding depth, infiltration rates and to better determine long-term maintenance regimes. All elements within the Cartridge Filter have been designed for easy safe and cost efficient cleaning by vacuum method. Please refer to the product maintenance guide for full cleaning and maintenance procedures. Page 22

24 13.0 Applications and Configurations The Cartridge Filter provides a cost effective and efficient system for removing stormwater contaminants such as nitrogen, phosphorous and heavy metals both in particulate and soluble forms. The system is capable of achieving low pollutant discharge levels and also has the flexibility to target contaminants specific to site requirements meeting a range of permit licences. Installed underground the system has a low impact footprint for both retrofitting and new development applications. Most residential, commercial and industrial developments today are designed using Water Sensitive Urban Design (WSUD'S) to achieve annual pollutant load reductions. The application of the Cartridge Filter provides a compact easy to install solution. As a modular precast concrete unit, it is supplied to site with all internal components pre-factory fitted ensuring simple on site installation of the unit. It has a range of applications including: Mining and bulk handling facilities; Industrial and commercial sites such as car parks and shopping centres; and High density residential housing developments. The ECF At-Source is designed specifically for field inlet applications. Ideally suited for small commercial car park applications with inlet flows ranging from L/s, it provides a compact cost efficient at-source treatment solution. The Off-Line Cartridge Filter Series has been designed specifically to cater for typical high density urban catchments where space limitations require a compact underground treatment solution. Genrally the system is installed off-line diverting a predetermined flow rate to the system for treatment. The system is unique in that it also includes a primary treatment litter basket, hydrocarbon retention baffle and fore bay chamber consisting of a baffle system to provide detention and settling of sedimentation prior to flows entering the cartridge filter chamber for further tertiary treatment. This system is ideally suited to medium high density catchments with inlet flows ranging from 19 88L/s depending on the number of cartridges installed.
