Membrane bioreactor

The biological processes in a membrane bioreactor (MBR) are almost the same as in an active sludge system, with the difference that the active sludge and the purified water are separated using membranes (instead of the precipitation and extraction with the conventional biological treatments).

The advantages of a membrane bioreactor over the conventional techniques are:

• The quality of the water after passage through a membrane (permeate) is good for re-use (water chain).
• The compact construction method, because (aeration tank) higher sludge volumes can be used in the reactor (higher load possible).

Logisticon has realised several MBR systems, which are still functioning to the complete satisfaction of the customers (including re-use of the permeate).
