Product Introduction

sealed cartridge bearingA filter press rubber membrane is a flexible, elastomer diaphragm used within a membrane filter press to apply mechanical pressure and further dewater the filter cake after the initial filtration cycle. This process significantly reduces moisture content and cycle time compared to a standard filter press.

Types Of Rubber Membranes

Fixed/Welded Membranes: These are made of 100% polypropylene, with the membrane face heat-welded to a core plate.

Pros: This design is free of joints, which prevents contamination and is therefore preferred for food applications.

Cons: If the membrane is damaged, the entire plate must be replaced, which can be costly and time-consuming.

Replaceable/Removable Diaphragms: These feature a polypropylene core and a separate, easily changeable rubber diaphragm.

Pros: This is the more cost-effective and quicker option for repairs, as only the diaphragm needs to be replaced if damaged.

Cons: Not ideal for applications with strict hygiene requirements due to the presence of joints.

Rubber Membrane Materials

The type of rubber or elastomer used for a filter press membrane is selected based on the specific chemical, temperature, and pressure conditions of the application.

EPDM: A durable thermoplastic elastomer suitable for many conditions.

NBR: A synthetic rubber for specific chemical conditions.

TPE: Thermoplastic elastomers are a common, stretchable, and chemical-resistant option.

FKM/Viton®: Fluorocarbon rubbers with superior thermal stability and chemical resistance.

Configurations

Membrane filter plates are often arranged in a "mixed pack" or "alternating pack," which is the most common and cost-effective setup.

Mixed pack: One membrane plate is alternated with one standard recessed chamber plate. This is more budget-friendly than using all membrane plates.

All membrane pack: Every plate in the press is a membrane plate for maximum dewatering capability, though this is a more costly option.

How They Work

Slurry is pumped into chambers, forming a filter cake, and then inflated membranes squeeze the cake for further dewatering before discharge.

Manufacturers And Suppliers

Companies like Micronics Engineered Filtration Group, M.W. Watermark, Matec Industries, Semperit, Met-Chem, and Ultra Filtech manufacture and supply these membranes, offering various options for different applications.
