Filter Speed

When the solid particles in the suspension are large and the particle size is uniform, the pores of the filtered residue layer are relatively smooth, and the speed of the filtrate passing through the filter residue layer is relatively large. The use of coagulant to aggregate the fine particles into larger agglomerates is beneficial to improve the filtration speed.

For the suspension with fast settling speed of solid particles, apply the filter on the upper part of the filter medium, so that the filtration direction is consistent with the direction of gravity, and the coarse particles settle first, which can reduce the clogging of the filter medium and the filter residue layer; in the difficult-to-filter suspension ( Such as colloid) mixed with coarser solid particles such as diatomite, expanded perlite, etc., can make the filter residue layer loose; when the filtrate viscosity is large, the suspension can be heated to reduce the viscosity. These measures can speed up filtration.
