Most drinking water systems use filters to collect, catch, or gather particles from an incoming flow. When the filter’s pores become clogged, they need to be cleaned. One of the best ways to clean a drinking water system’s filter is to '''backwash filtering''' it, meaning reversing the flow and increasing the velocity at which water passes back through the filter. This, in effect, blasts the clogged particles off of the filter. | |||
Although every filter is unique, the principles of backwashing are similar for all of them. One key ingredient to a good filter backwash is using clean water, usually out of the clear well, first storage tank, or distribution system. This Tech Brief examines the most common filters: conventional and direct filtration. These filters use either pressure or rapid rate gravity processes. | Although every filter is unique, the principles of backwashing are similar for all of them.
