Read MoreHorizontal pressure filters typically are used for larger plants since their layout maximizes filter area and minimizes footprint. Like rapid sand filters the residuals from pressure filters consist primarily of spent filter backwash. Spent filter backwash can be recycled to the treatment process to improve performance and reduce water losses
Read MoreThe controller can also be triggered to start a backwash by the pressure difference between the water entering the filter and the water leaving the filter. As particulates collect in the sand bed the pressure difference increases so a high pressure difference signals that the media bed is
