3 1 INTRODUCTION ABOUT THE UF- UF- ultrafiltration units provides short and long-term solutions for potable water supplies. The units are lightweight, transportable and easy to setup and operate the non-technical persons. With a long life span and minimal consulables the UF- is ideal for many filtration applications. When operational the UF- will provide a continuous supply of clean water. The unit will self clean at preset intervals and also requires a chemical clean every 150 hours. The chemical clean removes accumulations not removed by the regular backwash. Operator input is required at this time (see Operation the UF-). The UF- has been designed for quick and easy setup. Connections are plug-in requiring no hard-wiring of mains power. The UF- are stand-alone units requiring no additional operating equipment other than water pump, plumbing and tanks. Locate the UF- under cover with sufficient space around for installing plumbing connections and maintenance. AUTOMATED ULTRAFILTRATION UNITS MODEL OPTIONS: UFP100MONO (20-25 kl/day) Single (1) module automated UFP200DUAL (40-50 kl/day) Dual (2) module automated Commencing Filtration Once all electrical and plumbing connections are completed (see Setting Up the UF-) the UF- unit can be initiated to commence filtration operations (see OPERATING THE UF-). Filtration Operation Once operating, the UF- will run automatically and alternate between filtering and backwash cycles at pre-set times. The backwash cycle times can be varied (see OPERATING THE UF-). Pre-Filter Cleaning when Installed A pre-filter (if installed) should be cleaned regularly. The frequency of cleaning depends on contaminates in the feed water. Follow the manufacturer s recommendations for cleaning the pre-filter. Air Pump Filter Cleaning Cleaning of the air pump filter should be carried out periodically. Unleash the strap around the pump unit on the UF- and unscrew the knob on top of the unit to release the cover. Remove the filter and rinse by hand in water, wring dry and replace. Follow the manufacturer s instructions for cleaning the air filter. Practical Considerations UF Maintenance and Regular Inspections The ultrafiltration unit requires maintenance and regular inspections to ensure its continued operation. Keeping Potable Water Pipes Safe Pre flush hoses, taps, and other equipment with a chlorine solution is good practice to eliminate contamination prior to use for drinking water purposes. Use a concentration of 0.1% (1,000 parts per million) - add approximately 1 teaspoon of chlorine powder to 5 litres of water. UFP300TRI (60-70 kl/day) Tri (3) module automated UFP400QUAD ( kl/day) Quad (4) module automated Keeping Drinking Tanks Safe Storage of drinking water in tanks can result in a loss of water quality due to post contamination. Water tanks in hot climates may stay safe for a few days while in colder climates they may stay safe for weeks. To maintain water quality it is good practice to disinfect drinking water tanks with a small amount of chlorine to prevent the growth of unwanted organisms and pathogens in the stored water. Add sufficient chlorine to drinking water tanks to maintain a residual free chlorine level of between 0.2 to 0.5 milligrams per litre (mg/l). Use a water testing kit every few days to monitor the chlorine levels and make adjustments when necessary. As a guide for every 1,000-litres of tank water, add about 3/4 teaspoon of chlorine powder (at 65% available chlorine) or 1 1/2 teaspoons of chlorine powder (at 35% available chlorine). First, mix the chlorine in a small bucket of water to make a solution before adding to the water tank.

6 UF INTRODUCTION 4 SETUP Plumbing Connections It is important when you setting up the UF- that correct fittings and equipment be installed to ensure the unit will perform effectively: Provide water tanks (supply tank & filtrate tank) and water pump. Install float switches to water tanks. Install plumbing pipes and plug in electrical connections. Install Extra Equipment if required which may include: - Flow Sensor - Pre Filter (Spin Clean) - UV Disinfection Unit - Pressure Reducing Valve to supply Electrical Connections (underside of system controller) The UF- controller is designed for mains power (240/110 volts) external electrical plug-in connections. For this reason it is not necessary to engage an electrician to undertake installations providing only plug-in connections are used. The controller undertakes a number of functions including: Operating the 240 volt or 110 volt air pump Activating solenoid valves to regulate water and air flow thought the ultrafiltration unit Water pump operation for the supply of feed water to the ultrafiltration unit Receiving inputs from float switches signalling start up and shut down procedures Undertaking cleaning and backwash cycles Interacting with an operator for undertaking chemical cleaning cycles and other functions. System Controller Inputs and Outputs: Power Supply A 240 or 110 volt AC power supply (or suitable solar system) is required to operate the ultrafiltration unit. This is connected to the controller, which in turn operates of the ultrafiltration unit functions. Note: Air and water pumps should be matched to suit mains power supply. Electric Water Pump Connection If using an electric water pump for supplying feed water, connect the electrical connection from the pump to the electrical controller. Note: use a pump suitably rated for use with the ultrafiltration unit (see Feed Water Supply Options. Electric Air Pump Connection An ALITA brand linear air pump is supplied with the unit and pre-wired with a plug-in connection to the controller box. The UF- is supplied with 25mm (1 ) plumbing Connections together with an accessory kit containing extra fittings to assist with set up on site. The following connections are necessary: SV1 (dirty water in): connect plumbing pipes or hoses to a pump and/or header tank for supplying feed water to the UF-. SV2 (filtrate clean water out): connect plumbing pipes or hoses to supply clean water to a drinking water tank or other use. SV3 (backwash water out): connect plumbing pipes or hoses to a drainage outlet, which is also vented to an air vent outlet. Failure to vent to air will cause damage to the UF-. Backwash water from the UF- may also discharge contaminates and cleaning solutions which may require further treatment such as neutralisation prior to disposal. SV5 (filtrate flush backwash): connect plumbing pipes or hoses to a drainage outlet. MV1 (housing flush): connect plumbing pipes or hoses to a drainage outlet. MV1 allows the ultrafiltration unit to be drained of water for flushing purposes or for relocation. Feed Water Supply Options Electric Water Pump Small electric water pumps 25mm (1 ) are suitable for supplying feed water from a raw water supply tank directly to the ultrafiltration unit. Pumps with a power rating of 600 to 1200 watt and a pressure head of approximately 10 to 40metres (100 to 400 kpa) should be adequate for use. When considering pump sizing consult the pump performance curve tables to take into account pipe sizing, pipe length, suction & lift requirements together with friction loss for pumping water. Note: although the ultrafiltration unit is rated to a maximum pressure of 200 kpa the use of pumps exceeding that pressure (to maximum 400 kpa) are suitable for use subject to the pressure as measured on the ultrafiltration unit pressure gauge not exceeding 200 kpa when in filtrate mode. Header Tank Gravity Feed Water Supply Feed water can be supplied directly from elevated header tanks to the ultrafiltration unit. In such case consideration can be given to the removal of the flow control valve provided the flow rate through the unit does not exceed 18 litres per minute. Safety Precaution: As with all electrical devices the controller should be connected to a power supply protected with an approved electrical safety switch (also known as a residual current device or RCD). Mounting Brackets The UF- is supplied with mounting brackets and bolts to allow the unit to be secured to the floor and also to a wall if required.

7 5 SETTING UP THE UF- UF Pressure Control Water pressure supplied to the ultrafiltration unit should not exceed 200kPa (30psi) when the unit is in filtration mode. A pressure reducing valve (PRV) or pressure limiting valve (PLV) may need to be installed to control excessive water pressure. A PRV or PLV needs to be plumbed after a pre-filter to ensure its operation is not compromised by dirty feed water. Refer to PRV or PLV specifications to determine the pre-screen requirements to ensure UF units are not fouled by feed water. Fouling may render the UF units inoperable resulting in excess pressure entering and damaging the ultrafiltration unit. Pre-Filter Water supplied to the ultrafiltration unit should be pre-screened to 500 micron (0.5mm) or finer to protect solenoids and other valves from fouling. Unscreened or coarsely screened raw water may also reduce membrane operating life. A pre-filter should be installed on the feed water supply line prior to SV1 (solenoid valve 1). Aqua Solutions can supply an automated cyclonic pre-filter connected to the UF- controller. Flow Control A flow control valve (FCV) is installed on the ultrafiltration unit restricting water flow to a maximum of 18 litres per minute per housing shell. The FCV is ideally suited when an electric water pump is used to supply feed water to the ultrafiltration unit. In other instances where a pump is not used and a low-pressure gravity feed water supply is utilised, the FCV may excessively restrict water flow and may need to be replaced with other options - see Feed Water Supply Options for more details.

10 UF QUICK OPERATING GUIDE SETUP Ensure the UF- is set up correctly and functioning properly - refer to SETTING UP THE UF-. TO COMMENCE FILTRATION - TURN ON THE CONTROLLER Once the UF- is switched on it will fill with water and automatically go into filtration mode. No further inputs are required. In Filtration Mode the UF- will automatically alternate between filtration and cleaning mode (backwashing). If the water level in the supply tank becomes low or the filtrate tank becomes full, the UF- will automatically pause and when water levels change will resume again (providing float switches have been installed). During this process the screen displays will look like this: Loading settings. Please wait. Start up screen 2-5 seconds. 4 CHEMICAL CLEAN CEDURE - EVERY 150 HOURS To remove accumulated residue not cleaned by normal backwashing requires the addition of mild chemical solutions and allow the unit to soak for a few hours. After every 150 hours of actual operating time, the UF- Controller will flash and beep notifying the operator a chemical clean is required. At this time the operator needs to add a chlorine solution and sometimes a citric acid solution by following the procedure below: Open valves MV1 (at base of UF-) and flush for a few seconds and close valves again. Press to activate a Chemical Clean and follow onscreen prompts. Once activated you will be asked to select chemical type, add chemcial and replace cap (see main instructions on how to prepare a chlorine solution). Once completed, no further inputs are required.

Filtration Mode In Filtration Mode the UF- will automatically alternate between filtration and backwashing. During backwashing the UF- will shut down one shell at a time and undertake Air Scour which cleans each filter module. While this is occurring other filter shells will continue to function normally in filtration mode. During Filtration Mode when the water supply tank becomes low or the water filtrate tank becomes full, the system will automatically pause until this situation changes. The screen will indicate System Paused. Make sure float switches in the supply tank and filtrate tank are correctly installed (refer to Site Preparation ). Stop / Pause During any function, push NO B to pause or stop function. How the UF- Automatically Cleans The UF- uses two types of cleaning processes to keep the system running efficiently: Backwash Cleaning: Air scouring and flushing shakes loose contaminates from inside the filter module ad flushes them to waste. This occurs throughout the day on a timer system, which the operator can adjust. It can also work automatically if a flow sensor is installed (see optional extra equipment). Chemical Cleaning: Every 150 hours of run time the operator activates a chemical clean which soaks away contaminates not removed by the backwash cleaning. Once activated the UF- shuts down temporally to complete the soaking process after which the soak chemical is flushed away and the unit automatically returns to filtration mode. These processes are explained in more detail on the following pages.

12 UF OPERATING THE UF- 10 BACKWASH CLEANING CEDURE The UF- backwash timer settings can be varied to accommodate contaminate loadings in supply water to keep the unit running clean. During backwashing a combinated of air scour and flusing sequences shakes loose contaminates from filter fibres and flushes these to the waste outlet. To change backwash sequencing, press MODE followed by pressing A until desired mode number is displayed on the screen. Press to set the mode as outlined below: Changing Backwash Settings: The operator can vary backwashing modes as listed below: Mode 1: Backwash occurs every 60 mins - suitable for very clean supply water only Mode 2: Backwash occurs every 30 mins - suitable for most supply water applications Mode 3: Backwash occurs every 15 mins - suitable for highly turbid supply water Mode 4: Automatically activates additional backwashes when flow rates fall below pre-set values as nominated by the operator. Note: an Optional Extra flow sensor is required to be installed for this function to be undertaken. Manual Backwash Activation: Press A anytime while in filtration mode to manually activate a baskwash cycle. Note: The UF- is pre-set to MODE 3 setting. Variable Backwash Programmer (Optional Extra Equipment): This device plugs into the UF- controller instead of a flow sensor and allows the operator to nominate any desired backwash timer sequence. This would only be used for unique situations. Changing Filter Mode can only be undertaken while in filtration (not in backwash or chemical cleaning cycles). To change backwash mode PRESS MODE and follow screen prompts: Set Filter Mode. Mode -- Use A to change or push Ok. A Set Filter Mode. Mode 1 Use A to change or push Ok. A Set Filter Mode.

13 11 OPERATING THE UF- CHEMICAL CLEANING CEDURE UF How Chemical Cleaning Works Every 150 hours of accumulated filtration time the ultrafiltration unit requires a chemical clean. The added chemcials will soak the filtration module and assist in cleaning accumulated matter not removed by regular backwash. Once the clean is completed the chemicals discharge to waste. When a chemical clean is required, the on the controller will flash and beep and the operator must attend to add the required amount of chemicals (see Chemical Cleaning Mode). Chemical cleaning uses solutions to remove accumulated contaminates from the ultratfiltration unit. When a chemical clean is activated, the screen prompts will guide the operator. The operator will be asked to: Unscrew cap on top of the CHEMICAL TANK (located on each filter housing and add the chemical solution). Add the required chemical solution - Press. Replace cap and firmly tighten - Press. The UF- will automatically complete the chemical clean process. Note: Check O ring seal in cap located on chemical tank. A loss of the O ring seal will result in failure of the filtration unit to effectively undertake cleaning. There are two (2) types of chemical clean: 1) Chemical Cleaning using: CHLORINE (Chlorine Chemical Clean once every 150 hours) Chemical cleaning using chlorine removes accumulated organic matter. Chlorine comes as dry granules e.g. calcium hypochlorite (bleaching powder) or a liquid eg: sodium hypochlorite. To make a chlorine solution use a jug with 1.5 litres of water and add the amount of chlorine listed below. Stir with a mixing stick until dissolved. This should create a 0.2% chlorine solution once inside the filter housing. Note: See manufacturer s label on product for available chlorine concentrations. HOW MUCH CHLORINE TO USE: Chlorine powder with 65% available chlorine (650g / kg of chlorine) = 4 Teaspoons OR Chlorine powder with 55% available chlorine (550g / kg of chlorine) = 6 Teaspoons OR Chlorine powder with 35% available chlorine (350g/kg of chlorine) = 8 Teaspoons OR Chlorine powder with 25% available chlorine (250g / kg of chlorine) = 10 Teaspoons OR Liquid chlorine (Sodium Hyprochlorite) with 12% available chlorine = 200 millilitres Once dissolved, follow the screen prompts for adding the solutions chemical cleaning solution. 2) Chemical Clean using: CITRIC ACID (Citric Acid Chemical Clean once every 600 hours - after every 4th chlorine clean) Where iron or manganese is present in feed water (which is common in many locations) citric acid will assist removing accumulations. The frequency of a citric acid clean can vary subject to the concentration of iron or manganese. Where average levels of iron or manganese are present a citric acid chemical clean can be carried out once every 3 months. Always undertake a chlorine clean first before undertaking a citric acid clean. 1) Use 1.5 litres of water and add 500 grams of Citric Acid 2) Stir with a mixing stick until dissolved 3) Once dissolved, follow chemical cleaning process. Caution: When handling chemicals keep safe by wearing protective gloves, eyeglasses and clothing and avoid inhaling chemical fumes. Refer to Material Safety Data Sheets when handling chemicals.

14 UF OPERATING THE UF- 12 Activating a Chemical Clean Prior to activating a chemical clean, briefly open each MV1 valve for a few seconds (located at base of UF-) and close again. This flushes any accumulated matter that may have settled in the housing shells. To activate a chemical clean press and follow prompts Once activated, the screen will look like this: Chemical Clean. All steps must be completed! Are you sure? #1 Chemical Type >A Chlorine. >B Citric acid. to continue. #2 Add Chemical. Fill chem tank with chemical. to continue. #3 Chem Active. Replace, tighten cap on chem tank. to continue. NO Chemical clean mode. Be sure the supply tank will not empty and have chemical cleaner ready. Return to filtration. Push A to select Chlorine or B to select Citric Acid Fill chemical tank with chemical cleaner. Replace and tighten cap on the chemical tank. No further inputs are required from the operator until the next chemical clean. The UF- will automatically move the chemical solution into each shell where it will soak and clean the filter modules. During this time the chemical will be stirred periodically with air. At completion the chemicals will be flushed away and the system will rinse itself prior to the UF- automatically returning to Filtration Mode. Stop / Pause During any function, push NO B any time to pause or stop function.

18 UF SYSTEM ALERTS & DIAGNOSTICS 16 Pressure Alerts and Pre-filter Operation The following alerts can only be activated if optional extra sensors have been included: Pre Filter Operation. Triggered via backwash counter and flow sensor. Pre Filter Cycle X T-Rem 00:00:13 Flush Prefilter. If this screen is displayed the controller has detected a low flow rate. The pre filter will cycle 3 up to times to increase flow rate. If unsuccessful the system will trigger a backwash. If low flow is still detected the system will shut down and stop filtration. Pre Filter Cycle X T-Rem 00:00:12 Checking flow :12:45 The controller is checking if the flow rate has returned to normal, if so filtration will continue. Lowflow Backwash. T-Rem 00:05:12 Airscour 1 If the pre-filter cycles have not improved the flow rate the system will perform a Lowflow Backwash, If this improves the flow rate the system will return to filtration, if not the system will shut down with an alert. System blocked or pump flow restricted. See manual for fault diagnosis. If this screen is displayed the entire system must be checked for blockages. Check water pump for proper operation. If necessary contact manufacturer. High water pressure. Water pressure high System stopped. See filter manual for fault finding. If this screen is displayed when high water pressure has been detected. Check for blockages and correct water pump operation. Check filtrate outlet for blockages. Used to monitor an over-pressure situation in the filtrate output. Located on the filtrate line the water pressure sensor detects any over pressurisation of the system (beyond 250kPa) and immediately closes inlet supply. Flood Sensor: Located on the Air Scour Manifold the Flood Sensor detects water in an airline should there be a bypass failure of a Non-Return Valve. Should a bypass failure occur, supply water can surcharge through the air scour line, in such case, the flood sensor will activate causing the controller to shut off supply water, open the waste valve and run the air pump. This will prevent damage to the linear air scour pump. The UF- will attempt clear the line and retry the filtration process. If the sensor reactivates after two attempts to clear the line, the system will shut down. This is redundancy function designed to protect the air pump from possible water ingress.

20 UF OPTIONAL EXTRA EQUIPMENT 18 Optional extra equipment can be supplied for integrating with the UF- controller system to achieve other functions as outlined below: Flow Sensor (supplied by Aqua Solutions): Can be used to monitor water usage and also trigger other functions such as backwashing and pre-filter flush cleaning when low flow is detected. To install a flow sensor connect the unit to the filtrate outlet line using 1¼ BSP reducers. It can be installed unit-directional (either way) and uses low voltage electrical connections making it safe to handle and plugs into the UF- controller. Functions of the flow sensor include: 1) Check water flow as displayed on the UF- controller screen. This will display flow in actual time, not historical records of flow rates. 2) Activate UF- backwashing once water flow rates fall below pre-set values (as an alternative to the default backwash settings). The operator can program into the UF- controller the flow rate value used to activate backwashing. A reduced flow rate indicates a build up of contaminates on the filter fibres, which need to be cleaned by backwashing. Using a flow sensor to activate backwashes overrides the UF- default timer used to activate backwashes. Without a flow sensor the UF- will backwash at pre-set timer intervals of either 15, 30 or 60 minutes as nominated by the operator. With a flow sensor the UF- will backwash only whenever the flow rate falls below that programed into the controller by the operator. The integrated flow sensor back wash activation will repeat up to 3 times to restore the required flow rate. If flow rates are not restored the controller will assume a blockage has occurred and shut down the system. 17 FLOW SENSOR

21 19 OPTIONAL EXTRA EQUIPMENT UF Pre-Filter Spin Clean (supplied by Aqua Solutions): This self-cleaning unit when connected to the supply inlet line is activated by the UF- system controller at pre-set times or when water flow decreases as indicated by a flow sensor (if installed). Refer to the options below for set up and operational criteria: Pre-Filter Spin Clean installed with no Flow Sensor: A spin clean pre-filter can be added to the UF-. A pre-filter removes coarser grade contaminates from feed water, which in turn reduces loadings, the UF- unit. When using a spin clean pre-filter (without the addition of an integrated flow sensor) the UF- will activate a spin clean flush cycle linked to the number of UF- backwashes. The operator can programme the UF- to activate the spin clean pre-filter anywhere from every 4 to 99 backwash cycles undertaken by the UF-. The spin clean pre filter supplied by Aqua Solutions contains a motorised ball valve which is connected the UF- controller. When a spin clean is required the controller closes the raw water inlet solenoid valves (SV1) while at the same time opening the motorised ball valve on the spin clean filter. This creates a cyclonic rush of water through the spin clean unit flushing contaminate debris from the filter screen and sending to waster drainage. Once spin clean is completed the unit automatically returns to normal operation. Pre-Filter Spin Clean and Flow Sensor Installed: When both a flow sensor and spin clean pre-filter are integrated with the UF- controller, the spin clean pre-filter is activated by both of the following processes: a) By a timer based upon the programed backwashes cycles of the UF- (from 4 to 99 backwash cycles) as programed by the operator. b) Whenever supply flow rates fall below a pre-set level as programed by the operator. Notes on Spin-Clean and/or Flow Sensor operations: 1) When using a flow sensor to activate either a UF- back wash or a spin clean pre-filter flush, if normal flow rates are not restored to pre-set levels, the UF- controller will assume there is a problem and go into shut down mode. Reasons that could cause a low flow rate may include: Blockage in the plumbing line. Blockage in the pre-filter or other fittings. UF- filter module fouled with contaminates. Pump failure. Water leak. 2) When setting up a flow sensor and programing the UF- controller, make sure a water supply is available. To program the flow sensor, water must be flowing through the unit. 3) When operational the flow sensor is only operative when the UF- is in filtration mode. The reason for this is to avoid incorrect flow readings, which may otherwise be generated when UF- is in other modes such as backwash mode. 4) A flow sensor must be protected with some type of pre-filter to avoid potential damage by larger particles in the water supply. UV Disinfection or Dosing Pump Output: this output interfaces with the controller and switches a UV light or dosing pump on when any of the SV2 valves are activated. SPIN CLEAN PRE-FILTER
