Module Structure

Module Structure

Highly reliable membrane structure

Asahi Ksdeis proprieary double skin membrane structure provides ultrafilltration function to both inner and outer membrance surface.
This double skin structure also excels in the mechanical strength and has very rellable performance.

Product characteristics

Crossflow method

Crossflow controls the accumulation of foulant on the membrane surface and maintains high permeability.

Capable of backwashing

There are skin layers on both the inner and outer surfaces, making the membrane highly resistant to compression and insusceptible to breakage. Using the characteristic, the membrane can be back washed.

Clogging-less structure

Less susceptible to membrane clogging There are products with hollow fibers of larger inner diameter, which are less susceptible to membrane clogging by sludge.

High stability against chemicals

The membrane can be washed with an oxidizing agent, etc., and used over a wide pH range.

Simple module structure

Module construction is simple. A module consists of a few parts and is free of structural trouble. The original structure and manufacturing method achieved minimum dead space in the module and assure highly stable filtrate quality.
