02 | Commercial Filter Manual WATERCO FIBREGLASS FILTERS Waterco Commercial Fibreglass Vessels embody the latest in fibreglass winding technology Waterco Commercial Vessels consist of an inner shell of fiberglass reinforced polyester resin wound over with fibreglass filament. Waterco’s digitally controlled filament winding faultlessly winds continuous strands of high quality fibreglass filament under controlled tension to create a refined consistency and superior quality. There are no special tank linings which can corrode or electrolyse. MAXIMUM RATED PRESSURE Waterco Commercial Vessels can be supplied with maximum rated pressures of;... -
Page 5: Filtration
Commercial Filter Manual | FILTRATION Waterco Commercial Vessels can be configured to provide general filtration, multi-stage water treatment filtration, chemical and odor removal, or demineralisation. Designed for down-flow use, unfiltered water enters the vessel through the upper influent port. Once entering the distribution header, the water flows through a hydraulically balanced system of diverters strategically placed over the filter bed. Even distribution of the water is achieved throughout the filter tank, which results in low levels of turbulence and minimal differential pressure losses. Water flow paths are parallel and vertical at the surface of the filter media bed resulting in flow capabilities up to 49m3/m2/hr or 20 US gpm/ft2 velocity without creating channeling within the media bed (depending on media type). -
Page 6: Backwash (Reverse Flow)
BACKWASH (Reverse flow) Backwashing is the reversal of water flow through the media bed to cleanse the media. As a guide, the backwash cycle would occur when pressure differential reaches 50kPa / 7-10 psi above the clean filter pressure i.e. after installation or after backwash procedure and clean media. Waterco recommend the use of the Waterco Dual Pressure Gauge for all installations to assist in determining backwash requirements (This model for use for up to 4 bar applications only). Backwashing is achieved by reversing the water flow into the collection laterals or nozzle plate, up through the filter bed. Wastewater is then collected through the distribution header and exits through the top port. -

Air only followed by water flush Air + water Waterco does not recommended using air OR air and water at the same time without suitable design by a qualified hydraulic engineer. Air velocity is generally 50m3/m2/hr or 3-5 CFM/ft2 depending on method, and provides a more efficient backwash method saving up to 25% water per backwash. -

Page 12: Installation Media
WET TESTING Before adding any media to the filter, the filter must be filled with water and the system run in both filter and backwash modes to test for any possible leaks of the filter or pipework. Waterco vessels are pressure tested at the factory before shipping. It is possible though, that during transit the tank or fittings may have been damaged. Waterco does not accept any claim for the costs of media removal and replacement required where the filter was not adequately wet tested on site before filling with media. -

Page 18: Backwashing
16 | Commercial Filter Manual BACKWASHING The function of backwashing is to separate the deposited particles from the filter media grains and flush them from the filter bed. Backwashing is achieved by reversing the flow of water through the filter bed at a fairly high flow rate. This high flow rate expands the filter bed and the water flow carries the debris out to waste. CONDITIONS FOR BACKWASHING Time for backwashing is determined by the following conditions: The flow rate through the filter bed decreases until it is insufficient to meet the demand The removal efficiency of the filter bed decreases to the point where filter water quality... -

Page 20: Maintenance Guide
18 | Commercial Filter Manual MAINTENANCE GUIDE The filter media will only require replacement once it has reached the limits of its designated life. Refer to the product information of the particular filter media used. To ensure the maximum life of the selected filter media, please follow the procedures below: Backwash the filter regularly according to the instructions set under “BACKWASHING”. Refer to the specifications of the filter media used and implement regeneration procedures accordingly For closed loop systems such as swimming pools: Maintain a correct chemical balance of your pool / spa water. The chemical balance of water is a relationship between its pH, total alkalinity, calcium hardness and water temperature. -
