Membrane Activated Process

Highest purification quality and reuse of wastewater

The membrane bioreactor process is a biological wastewater treatment process that works according to the principle of the activated sludge process (aerobic biological treatment of organically polluted wastewater with activated sludge), except that the secondary sedimentation tank, which ensures biomass retention, is replaced by membrane filtration.

Membrane Technology

Membrane Bioreactor Process

The use of membrane technology greatly reduces the space required, as the structures necessary for the treatment process at municipal and industrial plants can be made up to 70 % smaller. In addition, the purification performance of the sewage treatment plant will be increased.

By using ultrafine ultrafiltration membranes, even the smallest solid particles are reliably retained.

Problems with the secondary clarifier such as scum or sludge drift are no longer a problem with this technology due to the move away from classical sedimentation to membrane filtration.

HUBER offers the membrane activated sludge process as a standardised plug&play solution in containerised design as a MENA-Water MBR sewage plant.

FAQ

Frequently Asked Questions

A membrane filter usually consists of a polymer membrane that is attached to a carrier support. The pore size of an ultrafiltration membrane is in the range of 2 – 100 nm. While water molecules can pass through the membrane, activated sludge flocs and also smallest solid particles are retained.

The membrane surface is cleaned by the introduction of air. The air bubbles flow over the membrane surface and remove the adhering solids. Furthermore, the membrane is also backwashed or subjected to chemical cleaning as required.

The MBR (membrane bioreactor) or membrane activated sludge process has several advantages over conventional wastewater treatment according to the activated sludge process, because the secondary sedimentation tank is replaced by membrane filtration. Since membrane filtration is much more space-saving than a secondary clarifier, the space requirement is significantly reduced. In addition, the biomass concentration in the aeration tank can be increased, and membrane filtration ensures that the clarification process effluent is free of solids.

MBR is the abbreviation for membrane bioreactor. A membrane bioreactor is used for biological wastewater treatment and works according to the membrane activated sludge process.
