(3.) Types on the Basis of Uses

Plate and frame type filter plate is composed of a solid filter plate and a hollow filter plate. It is mainly used in the oil industry. It can also be used as a kind of fine filtration equipment, which is suitable for industries with very few solid materials.

Chamber filter plate is composed of several filter plates with holes in the middle. It can be applied to most industries, with the characteristics of fast filtering speed and high filtering pressure.

Diaphragm press type filter plate is composed of a filter plate with a hole in the middle and a membrane plate which can be inflated to the inside. After filter pressing, air is pumped into the inner part of the membrane plate to further squeeze the filter cake and press it twice to further reduce the liquid content in the filter cake.
