5 What is Geotube Dewatering Technology? Geotube containers are custom fabricated with seaming techniques that withstand pressure during pumping operations. Available in 30, 45, 60, 90 and 120ft circumference, length according to requirements.

6 What is Geotube Dewatering Technology? Geotube units are constructed of a specially-engineered textile designed for dewatering. High flow rate allows residual materials to dewater, while containing solids. End Product is a safe beneficial nutrient, no odour, pathogens and pharmaceuticals well within set standards for land application or secondary composting

7 How Geotube Dewatering Technology Works The Geotube unit is pumped with flocculated sludge material. CONTAINMENT PHASE

8 How Geotube Dewatering Technology Works As the liquid escapes from the tube, solid particles are trapped inside. The pumping process is repeated until the tube is full. DEWATERING PHASE

9 How Geotube Dewatering Technology Works Eventually, the solids can be handled as dry material, increasing options for transportation and disposal. CONSOLIDATION PHASE Geotube technology has three phases when processing organics Dewatering Digestion Composting

22 The cost and complexity of traditional waste water treatment plants are making it more and more difficult for communities and industries to implement and afford Increasing regulations, budget deficits and skyrocketing costs created a demanded for an alternative waste water treatment that meet these needs The following provides that solution

23 Facts Ø In the wastewater treatment sector there has been little change in treatment options since the French developed collection systems and the septic tank in the late 1800 s. In 1913 engineers in the UK added aeration to create what is known as the activated sludge process. Diagram of the original septic tank, 1860

24 Facts Ø Since that time an entire industry has been following the same direction with some slight variations. Ø Activated / Extended Aeration Plant Ø Primary Only Treatment Plants, Solids Removal and Disinfection Ø Sequencing Batch Reactor (SBR) Ø Facultative/Aerated Lagoons Disadvantages of all Traditional Wastewater Treatment Methods Ø High capital cost Complex to operate Require large land area

25 What If There was a Wastewater Treatment Solution That Ø Had a capital and operational cost that was considerably less than current market solutions? Ø More affordable to communities with limited budgets? Ø Took up a much smaller foot print? Ø Was simpler to operate? Ø Gave treatment results that met or were below new Federal and existing provincial regulations? Ø Was modular and could be installed in steps to suit budgetary constraints? Ø Could retrofit an existing system or be a stand alone new system?

26 Biocord Reactors Biofilm is a natural aggregation of a complex community of microorganisms growing on a solid substrate. In traditional activated sludge plants the microorganisms are suspended in the sludge Biofilm formation

27 Biocord Reactors. Biocord was developed by the Japanese and has been in use for more then 30 years in a variety of applications. 10 different types of Biocord using numerous different polymer fibers create different affects on BOD and treatment results Clear Biocord Biocord Covered in micro-organism film

28 Biocord Reactors Ø Biocord can be installed on stainless steel racks or fixed to a surface frame Ø Coarse air diffusers slough off the excessive biofilm growth during high loading periods, this then settles as sludge to the collection system, this is the only regular maintenance. Ø The sludge then goes to a treatment system such as a Geotube Ø The outer layer of biofilm is aerobic, while the inner layer is anaerobic, allowing for quick regeneration of bacterial species after slough off Biocord installed on a rack Geotube Sludge Treatment System

29 Biocord Reactors Robert Delatolla, Ph.D. Assistant Professor, Civil Engineering, University of Ottawa; April 2012 We do see the new bio-film technologies available for wastewater treatment being increasingly considered and installed in Canada (with of course many instances where they still get completely overlooked based on "conventional" methods of treatment). Issues like nutrient removal, small footprints and increasing regulations have sort of driven their implementation in Canada as upgrade systems

30 Nitrogen Removal With Biocord Ø Nitrification and de-nitrification bacteria require a long time to develop, 3 to 6 weeks depending on temperature Ø In an activated sludge process, sludge is often wasted before these bacteria properly develop Ø With Biocord, there is a permanent fixture of bacterial mass in the system, giving the time required for the nitrogen removing bacteria to develop. Ø BOD removal bacteria also develop on Biocord Nitrosomonas (left) and Nitrobacter (right), the nitrification bacteria

31 Biocord Reactors Bonnechere Valley Demonstration Parameter Units Eganville WWTP input (Raw) Eganville MLSS Eganville WWTP Outlet (20-24 hour HRT) Typical Atlantic Canada WWTP effluent BioCord demonstration plant outlet (6 hour HRT) Eganville WWTP Discharge Criteria BOD 5 mg/l Total Suspended Solids mg/l Ammonia mg/l CCME 1.25 Phosphorous - Total mg/l COD mg/l TKN mg/l The Eganville WWTP operates at approximately 45-50% of design capacity, and because of this gives exceptional treatment results. It also uses chemical precipitation for phosphorus removal (as do most Ontario plants). The Biocord demonstration plant is was not designed for phosphorus removal even though it removed 70% it can however be configured to remove phosphorus biologically to meet discharge standards

32 Biocord Reactors Bonnechere Valley Demonstration Ø Instead of ramping up BOD and TSS concentration by mixing influent wastewater with sludge, the Biocord system brings BOD and TSS concentration down from the influent concentration Ø This allows for reduced contact time, smaller tank sizes and a sludge production reduction of 75-80% Biocord Treatment plant in Japan

33 Bio Cord Biofilm WWTP Flow Dynamics

34 Biocord Reactor Solutions Retrofit Existing Treatment Plants Ø Requires no additional tank construction Ø Operates as an IFAS (Integrated Fixed Film-Activated Sludge) Ø Provides a stable growth platform for BOD removal bacteria and slow-growing nitrification bacteria Ø Attached biomass concentration Ø Rapid, simple installation Ø 30% efficiency increase

35 Biocord Reactor Solutions Retrofit Lagoon Systems Ø Adds fixed biomass to the lagoon to increase biological treatment Ø Provide nitrification in cold temperatures Ø Fits in existing lagoon Ø Low capital costs

36 Lagoon Renewal

37 Biocord Reactor Solutions Purpose Built Biocord Treatment Plants Ø Biofilm or IFAS configurations Ø Minimal sludge production Ø Provides both nitrification and de- nitrification Ø Greater treatment capacity over same sized activated sludge plant (Reduced Contact Time) Ø Reduced aeration requirements over activated sludge Biocord Treatment plant in China

38 Costing Comparison: Eastern Canada A planned expansion of a subdivision in eastern Canada from 1800 to 10,100 people required additional capacity at the local wastewater treatment lagoon. Preliminary engineering indicated that additional lagoon cells would be required and that nearby land would need to be acquired, or a new mechanical plant would need to be constructed, costing between 20 to 30 Million dollars. Existing treatment Lagoon

39 Eastern Canada: BioCord Reactor Solution Working with the municipalities Engineering firm a solution using BioCord/Biofilm technology that was able to meet the wastewater treatment needs of the new population growth was developed using the existing lagoon, at a cost of $1.8 million. The expansion is designed to be phased over a 10 year period, reducing upfront capital costs as the reactors can be installed in modular form. BioCord Reactor

41 Costing Comparison: Newfoundland In Ontario a town of 1200 people required a new wastewater treatment plant to replace their existing extended aeration system. A new sequencing batch reactor (SBR) using traditional activated sludge technology was built in 2011, at a cost of $9.5 million. In Newfoundland Bishop Water Technologies, in conjunction with a local engineering firm, designed a wastewater treatment system using BioCord/Biofilm technology for a community of 1200 people that meet all provincial and federal regulations at a cost of $4.8 million. The reduced contact time and smaller tank sizes provided by BioCord technology significantly lowers capital costs.

42 Nutrient Removal in Rivers and Lakes Excessive concentrations of phosphorus and nitrogen in rivers is the primary cause of eutrophication, the appearance of algae and phytoplankton on surface waters during the summer. Lake Erie (August 2013)

43 Nutrient Removal in Rivers and Lakes BioCord can be installed into lakes and rivers to remove phosphorus and nitrogen. It provides a surface area for naturally occurring Biofilm to clean the water. BIoCord Floating Island Large scale seagrass type BioCord installation
