Filter speed of swimming pool filter

When the solid particles in the suspension are large and the particle size is uniform, the pores of the filtered filter residue layer are relatively smooth, and the filtrate passes through the filter residue layer at a higher speed. The use of coagulants to aggregate fine particles into larger agglomerates is beneficial to increase the filtration speed. For suspensions with fast settling speed, please apply a filter on top of the filter medium to make the filter direction consistent with the direction of gravity. The coarse particles settle first, which can reduce the clogging of the filter medium and the filter residue layer. Mix the difficult-to-filter suspension (such as colloid) with coarser solid particles (such as diatomaceous earth, expanded perlite, etc.) to loosen the filter residue layer; when the filtrate has a high viscosity, the suspension can be heated to Reduce viscosity. These measures can speed up the filtration rate.
