By eliminating those elements that contribute to pore clogging before membrane filtration or by preventing it while it is occurring in the filtration medium, this problem can be avoided. The second technique involves modifying the operational circumstances. In a moment of primary treatment, it might occur in one of the following areas:
The strategy for mitigating the phenomenon of blockage is based on reducing the filtration speed, working with less pressure, or controlling the flow inside the filter so that the phenomenon of sediment accumulation on the surface of the membrane is reduced, and thus the rate of pore blockage is reduced. And when it comes to lessening the biocenosis phenomena on the membrane's surface, sterilisation might be used sometimes.
The washing procedure seeks to extend the life of the membrane by removing materials that have been accumulated on it or inside its pores. When the treated water's flow velocity hits its lowest limit value, the pressure reaches its maximum limit, or the filtration system's allowed filtration duration is achieved, the washing process begins.
