How can we use water effectively, make it available and in the process protect the environment? The clear objective of MANN+HUMMEL is that we would like to use our technology to enable sustainable water management and efficient water treatment.

Recycling and waste water treatment is a key challenge of our time. Solutions are particularly required in regions where water is scarce in order to make this precious commodity available and usable. At MANN+HUMMEL and MICRODYN‑NADIR we are working on future-oriented products and innovative technology to achieve and control sustainable water management in industry and at a municipal level. We have therefore developed a module which is used in the membrane bioreactor (MBR) process. Our immersed BIO‑CEL® module based on a flat membrane is robust, easy to clean and effectively retains bacteria, solids and particulate materials.

We are increasingly using membrane filtration in the arid zones of the world in connection with biological waste water treatment. This enables us to recover industrial or process water from waste water. In addition, due to the superior quality of the treated water in comparison to conventional sewerage treatment plant technology, the water can be used to water plants or fields.

Our filtration solutions are widely used. The application areas include, for example, municipal sewerage treatment, the textile industry, tertiary filtration to remove effluent from sewerage treatment plants, treatment of waste water resulting from the production of cosmetics and foods and treatment of water which has been used to wash cars.

But we have also developed environmental solutions and products for the separation of fat‑soluble and finely distributed materials and treatment of animal faeces, which are able to convince our customers.

BIO-CEL® XL

Immersed MBR modules based on a flat membrane

In the membrane bioreactor (MBR) the BIO-CEL® module based on a flat membrane replaces the secondary sedimentation process. This allows MBR operation with very good effluent values and reduces the space requirement.
