Waterco Water Filter for Home
Ideal for water treatment applications, the Micron W & WD Filters provide an effective means to remove sediment from incoming water before direct use or storage in a tank. The Micron W Filter’s unique feature is its user friendly Multiport Valve (MPV), which controls and facilitates all the operational functions needed for the filter. The Micron W Filter can easily be applied for Carbon and Mixed Bed Filtration. Please consult a Waterco Stockist for more information. For models Waterco W250 and Waterco W300 MKII
Water flows from the source (eg. water mains, bore etc), through the Multiport Valve (MPV) and is directed downward to the top of the filter bed. As water flows through the filter bed, debris is trapped and clean water flows through the laterals and up the central tube. The clean water then flows back through the MPV and is channeled to the outlet.
For household use, the filter should preferably be sited within the household compound and immediately after the water meter. The filter unit should sit on a level concrete surface or a precast concrete slab of suitable strength.
The filter unit should be located near a drain, to minimise piping for waste and backwash. Where additional backwash water supply is required or desired, further plumbing arrangement will be needed.
Backwashing can be assisted by a current water tank storage system or with a pump activated auxiliary water storage tank.
Be sure to comply with the local plumbing codes. The filter may be plumbed into a drinking water system and would, therefore be subject to whichever local regulations that may apply. Be sure that all provisions for wastewater disposal meet local, state or national codes. Do not discharge water where it will cause flooding or damage
Take special care with the backwash waste line. If there is not an adequate air gap between the waste pipe outlet and the drain into which it discharges, a siphon may develop that will draw some of the drain waste back into the water filter.
This may result in undesirable “cross connection” between a safe and an unsafe water supply. If the incoming water pressure is higher than 60% of the maximum operating pressure of the tank, a Pressure Regulating Valve (PRV) must be installed upstream of the filter inlet.
The PRV should be set to 90% of the maximum operating pressure of the tank. If the incoming water pressure is less than 150kPa/ 22psi, adequate backwashing cannot be achieved. In such cases, a booster pump should be incorporated.
NOTE: All piping should be a minimum of:- - W250-300 - 20mm (3/4”) - W400 - 25mm (1”) - W500 and above - 40mm (1 1/2”)
For an optimum backwash, minimise back pressure by keeping pipe work to the drain as short as possible.
A by-pass piping arrangement should be incorporated, which allows the entire filter unit to be easily isolated for servicing and maintenance, while ensuring continuous water supply into the household.
