Our ProductsOur Products

Our standard product portfolio consists of hollow fibres and tubular membrane filtration modules that are used in a large range of dead-end and cross flow applications.

These applications can be found for example in drinking water production, clarification of wine, or in Membrane Bioreactors.

MEMBRANE BIOREACTORMEMBRANE BIOREACTOR

Conventional:

• low MLSS (3-5 g/l)

• low age activated sludge

• only floc forming bacteria

• only fast growing bacteria

• low chance for component-specific bacteria

• sludge carry-over

• effluent polishing required

MBR:

• medium MLSS (10-20 g/l)

• high age activated sludge

• all kind of bacteria survive

• less sludge production

• good chance for component-specific bacteria

• no sludge carry-over

• high quality effluent
