WebWhen water flows through a clogged filter, friction causes the water to lose energy, so that the water leaving the filter is under less pressure than the water entering the filter. Head loss is displayed on a head loss gauge. Once the head loss within the water filter has reached between 250 and 350 em, a filter should be backwashed. WebHead loss ¾Head loss of clean filter is 0.15 to 0.46 m ¾As filtration progresses, head loss increases ¾When head loss reaches 1.8 to 2.4 m, the filter is cleaned (backwashed)
