Conditions for backwash :-

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 the effluent quality deteriorates and is no longer acceptable.

If a pump is installed, backwash the unit if the pressure rises by 50kPa (7.2 psi) above start up pressure. If connected to water mains, the pressure rise is not an accurate indicator as mains pressure tends to fluctuate. It is best to rely on the flow rate.

Waterco recommends that you backwash the filter at least once every 2 week in a domestic installation. Importance of Backwashing Without regular backwashing, the filter will become clogged with debris.

This will reduce the performance of the filter. To keep the filter operating at it’s optimum performance, backwash regularly as described above.

As Waterco Water Filter filtration proceeds, the void areas in the medium become filled with debris filtered from the water. The pressure will start to rise and the flow of water will start diminishing. The filter will eventually become so clogged with debris that it will be necessary to perform a backwash.

Function of Backwash The function of backwashing is to separate the deposited particles from 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 rate. Waterco Water Filter Service Maintenance

This high rate expands the filter bed and the water collects the debris taking it to waste
