MBR Solutions by Berghof Membranes
Berghof Membranes offers a complete line of membrane solutions for MBR applications. See below a reference installation for more information on how we can help you overcome your wastewater treatment challenges.
Membrane bioreactors
A membrane bioreactor (MBR), widely used in industrial and municipal applications, is an effective wastewater treatment system that produces high quality effluent suitable for reuse applications.
The membranes retain the biomass and mixed liquor suspended solids (MLSS) within the bioreactor, thus producing effluent that is free of particles, bacteria and viruses. MBRs remove between 96-99% of COD, compared to 95% in conventional activated sludge processes.
Additionally, MBRs can be operated at higher MLSS concentrations of up to 30 g/L.

Automotive Industry
A large truck manufacturer produces two wastewater streams: (1) industrial wastewater containing oil and metals with a high COD concentration, and (2) common wastewater stream containing high levels of organic matter from the factory‘s 3,000 employees. The volume and strength of the combined wastewater vary considerably from day to day. They requested a wastewater system to effectively treat the variation of wastewater stream.
MBR
In an effort to minimize their short and long-term environmental impact, industries across the globe are facing increasing challenges and costs in the treatment of their process wastewater. As a result, many of these industries have built their own treatment systems in order to treat and reuse process streams, reducing discharge costs to municipal treatment plants and recovering valuable products from effluent.
Traditional wastewater treatment plants consist of pre-treatment systems to capture large floating particles and coarse suspensions (e.g. wood, textile, plastic and stones), followed by biological aerobic digestion that converts organic waste into carbon dioxide, nitrogen gas and water.
After the biological process, the cleaned water is typically separated by gravitational force in settlers or clarifiers in which part of the biomass is then fed again to the biological process. Excess biomass then flows to the thickener for further dehydration.
The last step of the MBR technology filtration process consists of granular (sand) filtration and a chemical treatment which filters and decontaminates the solution from pathogenic microorganisms.

Food and Beverage Industry
Holland Malt is renowned worldwide for the quality of its malt production which involves three main processes: (1) steeping, (2) germination, (3) kilning and roasting.
Holland Malt aims to double its current capacity by 2019. The company has limited access to municipal water, therefore the company is forced to reuse their process water.
Read in the MBR project reference installation overview and see how the Dutch malt producer meets the production expansion challenges of the current capacity and see how the wastewater treatment plant played an incremental role.
