SELF-CLEANING BACKWASH FILTERS
In this type of filter, the cartridges is washed by taking advantage of a part of the flow of clear liquid coming out of the filter. The liquid is forced to flow in the opposite direction, washing the cartridges.
In this way, the element concerned is cleaned up and the pressure difference returns to average values. Even in this solution, there is a loss of fluid during the cleaning cycle and, therefore, a drop in flow rate.
