About Membion

Membion GmbH specializes in advanced membrane technology designed for efficient wastewater treatment. The company's core product is its hollow fiber membranes, which utilize a unique 'seaweed principle' to minimize pre-treatment requirements and prevent clogging. These membranes are immersed in the sludge of the biological stage and use a vacuum to draw crystal clear water through the membrane walls, retaining solids and particulates on the outside. This design makes the filters resistant to hairs and fibrous compounds, simplifying the pre-treatment process. Membion serves clients in the wastewater treatment industry, including municipal and industrial sectors. The company operates in the environmental technology market and generates revenue through the sale of its membrane products and related services.
