armbr® - ARTAS membrane bioreactor system

In light of scarce resources, rising costs for drinking water and wastewater treatment, and stricter environmental regulations, ARTAS offers a permanent, sustainable solution: the armbr® packaged membrane bioreactor system.

armbr® combines sludge and water separation using membranes and utilizes flat plate or hollow fiber membrane modules. It can be installed either in the aeration tank or in a separate downstream membrane reactor. MBR modules often operate entirely in the aeration tank and require bottom aeration. With armbr®, we achieve extremely low effluent values; the membranes have a disinfecting effect as bacteria are retained. Unlike conventional aeration tanks, there is no sludge backflow with armbr®.

Wastewater treatment plants that use the membrane bioreactor (MBR) process have high requirements for wastewater quality or face special challenges. Here are a few examples:

• Hospitals: MBR technology is often used in hospital wastewater treatment plants to purify wastewater from trace substances and drug residues.
• Industrial applications: Especially in the food, textile, and metal finishing industries, where high concentrations of organic substances and solids are present in the wastewater.
• Municipal wastewater treatment plants: Cities and municipalities use MBR technology to ensure high wastewater quality and meet legal requirements.
• Hotels, vacation homes, and resorts, nature reserves: These facilities benefit from the compact design and high efficiency of MBR systems to save space while ensuring high water quality.

MBR systems offer advantages such as 100% biomass retention, suspended solids-free and low-germ effluent, and extensive
