Page 3: Introduction
Organic Scavenger Installation, Operation and Maintenance Guide Introduction Tannins are a common class of organic compounds in upland water and give the water a yellow/brown tint. In highland (peaty) areas where water runs off peat the water can be virtually brown. Organic scavenging systems use resin to hold these organics which are periodically backwashed away with brine. Typically, every 25 litres of resin will take out 2000ppm of organic colour before it needs regenerating. An easy test you can try at home is to leave a glass of the water overnight. If the colour settles to the bottom of the glass the discolouration is likely caused by iron and/or manganese. If the colour remains the same it is likely caused by tannins. How an Organic Scavenger works An organic scavenger is an ion exchange system consists of a pressure vessel filled with resin. Located on the top of the pressure vessel is the control valve. The water is passed through the control valve and down through the vessel. As the water passes across the resin bed, the colour compounds attach to the resin. Periodically, depending on how much water is used, the resin needs to be refreshed. This is done by flushing a small amount of salt (stored in an external brine tank), though the resin vessel. Once this process has been completed the resin is refreshed and ready to begin again. 3 • GAPS Water Treatment 2022 • www.gapswater.co.uk • sales@gapswater.co.uk • 01706 521074... -

Page 5: Installation
Organic Scavenger Installation, Operation and Maintenance Guide 1. Installation Please observe the local regulations concerning the installation of your system. Check that you have allowed space for access to the unit for possible future maintenance. This installation may require plumbing work and will require an electrical outlet to be fitted near the system. This guide does not include plumbing directions. Only attempt this if you have the necessary skills. 1.1 Pre‐installation checks o The area needs to be level o Frost free o Access to electricity o Access to open drain. o Check the incoming water quality is within any parameters specified for that media (contact your supplier). o Incoming water pressure is between 2 and 8 bar (preferably approx. 4 bar) o Water temperature between 3ºC and 45ºC. 1.2 Fitting the Distribution System Systems up to 13” x 54” (75 litres) have a simple riser tube and bottom screen. The bottom screen will be pre‐glued so no further assembly is required. Simply place the riser tube with bottom screen into the vessel 5 • GAPS Water Treatment 2022 • www.gapswater.co.uk • sales@gapswater.co.uk • 01706 521074... - Page 6 Organic Scavenger Installation, Operation and Maintenance Guide For larger systems bottom laterals are used. These needs to be assembled inside the vessel Move the vessel into its final position as it will be difficult to move once the media has been added. 6 • GAPS Water Treatment 2022 • www.gapswater.co.uk • sales@gapswater.co.uk • 01706 521074...

Page 7: Adding The Media
Organic Scavenger Installation, Operation and Maintenance Guide 1.3 Adding the Media Block the top of the riser tube to stop media getting down the tube. This can be accomplished with tape or a small plastic bag over the end of the tube. Fill the vessel with water until it around a third full. This will prevent the bottom screen from getting damaged when you add the media. It will also allow enough movement of the riser tube when the media is added for you to re‐centre. Add the supplied media but ensure you leave around 30% free space above the media (there may be some media left over). This is so the media can expand into the space during regeneration allowing sediment and contaminants to be washed away. It also allows the water to pass more evenly through the media. You may want to employ a funnel to make this process easier (this can be bought as an optional extra). The media can be poured from the bag but we recommend using a smaller container to scoop out the media and pour into the vessel. Once complete unblock the riser tube. 7 • GAPS Water Treatment 2022 • www.gapswater.co.uk • sales@gapswater.co.uk • 01706 521074... -
Page 8: Fitting The Valve
Organic Scavenger Installation, Operation and Maintenance Guide 1.4 Fitting the valve Add a small amount of silicone grease to the valve outer and inner o‐rings Fit the lower screen to the bottom of the valve. This is a bayonet fitting (twist to lock into place). Slide the valve onto the riser tube ensuring the riser tube is fully inserted into the valve. Gently place it onto the vessel threads and screw onto the thread in a clockwise direction until it squeezes tightly onto the main o‐ring. Then finally give the valve a final tighten by tapping the rear side of the valve with the palm of your hand. 8 • GAPS Water Treatment 2022 • www.gapswater.co.uk • sales@gapswater.co.uk • 01706 521074... -
Page 9: Brine Tank Connections
Organic Scavenger Installation, Operation and Maintenance Guide 1.5 Brine Tank Connections Attach the brine line to the brine connection on the brine tank and the brine inlet/outlet on the Clack valve The brine system consists of a moulded polyethylene tank into which the brine well and brine pick up are assembled. The tank forms the salt storage container. The brine pick‐up tube is connected to the pipe from the control valve which sucks the brine from the tank. At the bottom of the brine pick‐up tube is an air check valve. This serves to prevent air entering the valve when all the brine has been drawn in. Air in the system could cause spurting and 'hammering' at the taps or outlets. 9 • GAPS Water Treatment 2022 • www.gapswater.co.uk • sales@gapswater.co.uk • 01706 521074... -

Organic Scavenger Installation, Operation and Maintenance Guide 1.6 Connecting your water supply (Further notes on plumbing your system in can be found at the back of the manual). Connect your pipe work to the inlet / outlet connections; use the supplied tails provide for 1” and 1.25” valves or direct BSP threaded connections on the 1.5” or 2” valves. For the 1” and 1.25” valves an optional bypass valve is available which fits to the back of the valve and allows you to isolate the system when out of service (eg during routine maintenance) Flexible hoses are available to make your installation easier (1” only) 10 • GAPS Water Treatment 2022 • www.gapswater.co.uk • sales@gapswater.co.uk • 01706 521074... -
Page 11: Drain Line Flow Control
Organic Scavenger Installation, Operation and Maintenance Guide 1.7 Drain Line Flow Control This is possibly the most important component so it is important to check that it has been installed. The DLFC controls the backwash flow rate and without it the system will not function correctly. On most of the valves the DLFC is internal but easy to check. Simply pull the red tag on the drain fitting and remove the complete fitting. The DLFC is a small rubber disk with a hole in the centre located on the bottom of the fitting. Larger systems have an external DLFC which can be dismantled to check the DLFC is fitted. 11 • GAPS Water Treatment 2022 • www.gapswater.co.uk • sales@gapswater.co.uk • 01706 521074... - Page 12 Organic Scavenger Installation, Operation and Maintenance Guide A hose barb fitting is included for the drain on the smaller systems allowing you to easily connect a braided hose which can be secured with a jubilee clip or similar should you choose. You can also utilise the male threaded fitting to customise the drain for your preferred pipework. 12 • GAPS Water Treatment 2022 • www.gapswater.co.uk • sales@gapswater.co.uk • 01706 521074...

Page 24: Commissioning The System
Organic Scavenger Installation, Operation and Maintenance Guide 3. Commissioning the System With the system fully plumbed in and the valve programmed commissioning can start 3.1 Regeneration When the system is fully functional the regeneration will happen at the pre‐ set time (see programming the valve section). However, running a manual regeneration during commissioning is the best way of removing air from the system, bedding in the resin and flushing the system through. Fill the brine tank with approximately 100mm of water and fill the brine tank with tablet salt or 3/4 full if using granular salt (SALT IS NOT SUPPLED WITH YOUR KIT BUT CAN BE PURCHASED AS AN EXTRA). Under no circumstances use cooking salt or Pure Vacuum Dried (PVD) salt to fill the cabinet as either of these will damage the resin and the internal components of the regeneration valve and brine draw system. Make sure the water inlet and outlet are closed. Press and hold the REGEN button for 3 seconds. The piston will move to the backwash position. Slowly half open the water inlet to the system, and then slowly open the outlet to allow the air to be purged from the system. Once this has been done you can fully open the inlet and outlet and allow the system to continue through the regeneration cycle, this will allow you to check for leaks and also purge any remaining air from the system. After a backwash the system will move through a brine draw routine, rinse and fill before stopping in the service position…. 24 • GAPS Water Treatment 2022 • www.gapswater.co.uk • sales@gapswater.co.uk • 01706 521074... - Page 25 Organic Scavenger Installation, Operation and Maintenance Guide Stages of Regeneration…. In normal service the water passes through the inlet, down through the resin, up the riser tube to the outlet The first stage of regeneration is the backwash. The valve reverses the flow of water so that water now travels down the riser and up through the resin which lifts the bed and loosens any debris that may be trapped in the resin. The water then goes to waste. During this stage water is sucked from the brine tank. The concentrated brine is mixed with water from the inlet to reduce the concentration to the correct level. It travels down the riser and up through the resin, when the correct amount of brine has been drawn water from the inlet continues to be drawn up through the resin to push the remaining brine through the resin. This process exchanges the organic molecules attached to the resin for sodium ions in the brine thus refreshing the resin and making it ready to attract organics again. During commissioning it is important to observe that water is being sucked from the brine tank and going to drain During Rapid rinse water is passed down through the resin and up the riser (same as in service) then to drain. This stage flushes out any residual salt and organics that might be present and re‐beds the resin ready for use. 25 • GAPS Water Treatment 2022 • www.gapswater.co.uk • sales@gapswater.co.uk • 01706 521074...
- Page 26 Organic Scavenger Installation, Operation and Maintenance Guide During brine refill a quantity of water sufficient to dissolve the correct amount of salt for the next regeneration is passed through the resin into the brine tank to ensure treated water is used to make the brine for the next regeneration. The unit will automatically go back into service after regeneration is complete. For new systems or after a media change it may be necessary to run two regenerations to fully charge the media (check the water at the end of the backwash is running clear). To initiate a delayed regeneration press the regeneration button once quickly this will start flashing Regen Today in the bottom left corner of the screen and the system will regenerate at the pre‐set regeneration time. If you wish to cancel this just press the regeneration button again and the display will disappear. To initiate an immediate regeneration press and hold the regeneration button until the valve motor starts to turn. If during a regeneration cycle you need to skip through the cycle this can be done in the following way. To skip to the next stage quickly press the regeneration button and this will take it to the next stage of the regeneration, this can be repeated to get to the end of the regeneration cycle. 26 • GAPS Water Treatment 2022 • www.gapswater.co.uk • sales@gapswater.co.uk • 01706 521074...

Page 27: Routine Maintenance
Organic Scavenger Installation, Operation and Maintenance Guide 4. Routine Maintenance Your system is designed to run with the minimum of maintenance and does not normally require much adjustment. Weekly Check the salt level (this may need to be done more regularly dependant on consumption) The salt level should always be above the water level. Check there is no sign of damage or leaks, Check the quality of the treated water. Monthly Check the quality of the incoming water to see if it has changed significantly. Yearly Check for leaks or damage. Caustic Soda Regeneration If you find your resin becomes less effective over time it may need regenerating with a caustic soda solution. Use 4g of caustic soda per litre of resin. The most effective way of passing the caustic soda soltion through the resin is to disconnect the brine line from the brine tank and place it in a bucket with your solution. Put the unit into immediate regeneration by pressung the REGEN button for 3 seconds. Allow it to go through the complete regeneration ‐ it will draw from the bucket of caustic soda soltion during the brine draw part of the cycle. If the resin is badly fouled you may need to repeat. 27 • GAPS Water Treatment 2022 • www.gapswater.co.uk • sales@gapswater.co.uk • 01706 521074... -

Page 32: Typical Installation Layouts
Organic Scavenger Installation, Operation and Maintenance Guide 6. Typical Installation Layouts In this example a 20 micron sediment pre‐filter has been added. The organic scavenger is fitted with a bypass valve so that the system can easily be isolated and the inlet water will bypass the system so there is no loss of water. Without the bypass valve we recommend that you use your pipework to create a bypass as shown in the diagram below. 32 • GAPS Water Treatment 2022 • www.gapswater.co.uk • sales@gapswater.co.uk • 01706 521074... - Page 33 Organic Scavenger Installation, Operation and Maintenance Guide This is an example of quite a common set up treating water with organics, iron and managese. The organic scavenger works better with lower pH water however the filox system needs a pH of 7 for iron removal and 8 for manganese so in this example the pH needed to be raised with a pH correction system. Order of filtration: 20 micron sediment filter ‐ this protects the organic scavenger Organic scavenger ‐ removes organics pH correction ‐ Raises pH to allow the filox system to work Filox ‐ removes iron and manganese 5 micron sediment filter ‐ pre‐filtration for the UV. This makes sure microbes don't hide behind sediment and avoid getting a full dose of UV UV ‐ kills bacteria, viruses, spoures and moulds. 33 • GAPS Water Treatment 2022 • www.gapswater.co.uk • sales@gapswater.co.uk • 01706 521074...
- Page 34 Organic Scavenger Installation, Operation and Maintenance Guide In this example the water has high tubidity, iron and organics, the pH is over 7. As pH is not a factor the organic scavenger can be placed after the turbidex and iron filter which will help to protect the resin. Turbidex ‐ removes sediment in the water down to 5 micron (nominal) which not only makes the water clearer it also acts as a pre‐filter for the filox and organic scavenger systems Filox ‐ removes iron and manganese Organic scavenger ‐ removes organics 5 micron sediment filter ‐ pre‐filtration for the UV. This makes sure microbes don't hide behind sediment and avoid getting a full dose of UV UV ‐ kills bacteria, viruses, spoures and moulds. 34 • GAPS Water Treatment 2022 • www.gapswater.co.uk • sales@gapswater.co.uk • 01706 521074...

Page 35: Further Installation Notes
Organic Scavenger Installation, Operation and Maintenance Guide 7.0 Further Installation Notes 7.1 MECHANICAL 7.1.1 Foundation/Drainage The organic scavenger will not require any special foundations, provided that a firm, level area which is capable of supporting the working weight is available. Unwanted water from the regeneration process must flow to drain, and so an open drain or gully, capable of passing the necessary flow is required. The drain may be at a level no higher than 500mm above the softener valve. A second drain is required for the brine tank overflow. This is a safety drain which will only discharge water if there is a malfunction in the control valve. Where possible this should be installed through an outside wall like a cistern overflow, where it will give a visual indication of any failure. 7.1.2 Operating Space Access will be required to refill the brine tank, and to carry out adjustments or maintenance on the equipment. It is therefore recommended that a minimum of 500mm clearance be allowed in front of the unit for this purpose. 7.1.3 Incoming Water The raw water to be fed to the organic scavenger must comply with the following:‐ 1. Available at all times at a flow equal to the required service flow or greater 2. At a pressure between 1.7 and 5.5 bar 3. Temperature between 1 and 40˚C 4. Suspended solids less than 1 ppm 5. Iron less than 0.2 ppm, Manganese less than 0.1 ppm, Free Chlorine less than 1 ppm if temperature is less than 15˚C, less than 0.3 ppm if temperature higher (up to 30˚C) 35 • GAPS Water Treatment 2022 • www.gapswater.co.uk • sales@gapswater.co.uk • 01706 521074... -
Page 36: Pipework
Organic Scavenger Installation, Operation and Maintenance Guide 7.1.4 Pipework Pipework to be connected to the organic scavenger should not have an excessive amount of hardness scale deposit. Piping that is heavily built up with scale (or Iron deposits) should be replaced. Make sure that the pipework can be connected to the scavenger in such a way as to impose no stresses on the control valve, and that it is properly aligned and supported. A system for the complete by‐passing and isolation of the scavenger should be installed 7.1.5 Water Supply Company Requirements It is essential that if the equipment is to be connected directly to a mains water supply, the local bylaws must be adhered to. These cover both plumbing and the prevention of backflow into the mains. If there is any doubt, the local water inspector should be consulted, but in general, the installation of a 'Double check valve assembly' conforming to BS6282 part 2 will be required in the feed pipework to the scavenger. If the pressure available from the mains is not adequate it will be necessary to install a booster pump arrangement. Such a system would be covered by additional bylaws, and the water storage tank needed must comply with these. 7.2 ELECTRICAL A continuous supply is required by the scavenger. A transformer is provided, which should be connected to an uninterrupted mains supply, which is separately 1 Amp fused, and does not have any additional switch. It is recommended that the transformer be attached to a nearby wall, within 500 mm of the softener in an area free from water spray or excessive heat or condensation. Electrical installation is very straightforward, but should still be carried out by a competent electrician, and must conform to the appropriate standards of safety. 36 • GAPS Water Treatment 2022 • www.gapswater.co.uk • sales@gapswater.co.uk • 01706 521074...
