The differance among plate-frame filter press, recessed plate filter press and membrane filter press.

 

Due to the structure of filter press prototype, people are accustomed to call all the kinds of filter presses as "Plate and frame filter press". As the development of history or productivity, even though not so much changes in the fundamental theory and basic structure of a filter press, but the structure or materials of filter plates are diversified and with much significantly optimized .

 

Normally the membrane plate and frame filter press, like "membrane plate and frame" such statement is not existing. The real membrane filter press is based on the improvement of recessed plate filter press, and recessed plate filter press is the derived from the optimization design of the plate and frame filter press.

 

The most significant difference is the structural form among plate-frame filter press, recessed plate filter press and membrane filter press.

 

1. The filter plate pack of plate-frame filter press is consist of alternating filter plate and filter frame; 

2. The plate pack of recessed plate filter press is made up from recessed filter plate only;

3. And the plate pack of membrane filter press is consist from membrane filter plate, which is made from TPE elastomer for main material and a litte bit same in structure as recessed plate, and alternated arranged with recessed plate(or membrane plate only) to from the plate pack of membrane filter press.
