MBR membrane bioreactor

The membrane bioreactor (MBR) is a novel water treatment technology that combines a membrane separation unit with a biological treatment unit. Using membrane modules instead of secondary sedimentation tanks, the bioreactor maintains a high activated sludge concentration, reducing the footprint of wastewater treatment facilities and reducing sludge production by keeping the sludge load low. Compared with traditional biological water treatment technologies, MBR offers the following key advantages: high treatment efficiency and excellent effluent quality; compact equipment with a small footprint; and easy automation and simplified operation and management. Since the 1980s, this technology has garnered increasing attention and become a research hotspot. MBRs are now used in over a dozen countries, including the United States, Germany, France, and Egypt, with scales ranging from 6 to 13,000 m³/d.

Application areas

Organic wastewater treatment

Wastewater treatment for beverage factories, distilleries, food factories, livestock farms, slaughterhouses, dyeing and finishing plants, leather factories, and pulp mills

Wastewater treatment for pharmaceutical plants and high-concentration organic wastewater treatment plants

Process improvements for existing wastewater treatment plants

Pre-treatment for reverse osmosis systems

Wastewater reuse

Large-scale municipal wastewater treatment and reuse, community domestic wastewater reuse, department stores, office buildings,

Wastewater treatment and reuse in restaurants or scenic spots

Surface water purification

Wastewater recovery and reuse in car washes and ships

Direct filtration of effluent completely replaces sand filtration. Reduces operator labor, backwashing is extremely fast, and there is no backwash water. Reduces SS to below 10, but often approaches zero.

Replaces traditional RO pre-treatment. Replaces pre-treatment for pure water production.

Groundwater sand filtration.

Combined with MBR technology, it eliminates the need for sedimentation tanks, sludge thickening tanks, sand filters, and other land-saving measures. It significantly reduces COD and BOD. Especially for... BOD removal rates are exceptionally high, with values ​​below 20 considered normal.

The MBR process, combined with A/O and A2/O processes, can significantly reduce nitrogen and phosphorus, making it suitable for water quality and water source protection areas.

Booming in Europe, America, and mainland China, everyone is brainstorming how to use it in conjunction with other processes, such as aquaculture water purification, mining, and water dispensers. Applications of deformed hollow fiber membranes.
