BIO-CEL® submerged modules - Submerged Modules

The BIO-CEL^® module allows for fantastic application possibilities in the field of municipal and industrial wastewater treatment as a backwashable module with all of the advantages of flat membranes and with the packing density of a hollow-fibre module without the disadvantages.

Membrane bioreactors are the next generation of activated sludge

waste water treatment processes. The BIO-CEL^® module replaces

the conventional clarifier for the treated water from the biomass.

The BIO-CEL^® Membrane Module is the efficient, reliable and future

oriented solution, which significantly increases the purification

rate, creates a discharge absolutely free of solids and thanks

to an ultrafiltration membrane, the best discharge values.

BIO-CEL^® combines the advantages of classical plate and frame

and hollow fiber modules without the disadvantages. It has the

packing density of a hollow fiber module, is back flushable like a

hollow fiber module and has the defined channels of a plate and

frame module. This new development consists of a backflushable

membrane pocket, where the backflushability is reached by a laminated

construction of the membrane support material to the spacer

material, creating a self supporting membrane sandwich only 2 mm

thick. An extremely high packing density is achieved with very low

weight, as is normally possible only when using hollow fibers.

The optimized membrane sandwich allows for a constant permeate

flow and a highly effective back flush over the entire membrane

surface. By using a flat sheet membrane, braiding is avoided and

also due to the open channel construction, sludge deposition and sticking of fibres has been reduced to a minimum.
