An apparatus used for the batch separation of solid particles from a liquid slurry. It consists of cloths stretched across a metal plate with a rippled surface and sealed in a metal frame. A number of plates, cloths, and frames are firmly sandwiched together to ensure no leakage from the sides. The liquid slurry to be separated is pumped into each compartment formed by the frames through channels onto one side of the cloth. The cloth allows the liquid to pass through while retaining the solids or filtrate, which builds up as a cake. This corresponds to a build-up of pressure and a slow reduction in the rate of flow. The filtration process is halted once a sizable cake has built up. The plate and frames are then decoupled and the cake manually removed from the cloths. The cleaned cloths are then reused.
