Membrane Press Filter

Membrane Press Filter Function and Working Method

The Membrane Press Filter operates through a systematic workflow: Feed → Filter → Discharge. The feed material, containing a mixture of solids and liquids, is pumped into the filter by a diaphragm pump. Inside the filter, the mixture is subjected to high - pressure hydraulic pressing, which forces the liquid through the membrane while retaining the solids. The filtered liquid is collected and discharged, while the solid residues are removed by gravity. This method ensures efficient separation of solids and liquids, producing clarified liquid and concentrated solid waste.

Membrane Press Filter Material and Construction

The Membrane Press Filter is constructed from either carbon steel or stainless steel 304. Carbon steel provides robustness and durability for general - purpose applications, while stainless steel 304 is used in scenarios where corrosion resistance and hygiene are critical, such as in the final stages of oil refining and processing.

Membrane Press Filter Key Features
