History has shown that cleaning wastewater  streams with chemicals that contain high pH values achieves the best results. A major disadvantage is that many membranes are not robust enough to withstand the highly concentrated alkaline detergents, resulting in wear and tear of the membrane and degradation of the membrane’s performance and service life.

With this in mind, Berghof Membranes has developed its line of robust Chemical Resistant (CR) membrane modules. The resistance to a wide variety of chemicals and pH values (2 – 12) means that our CR membranes are ideally suited for applications with high-strength wastewater or process streams.

In addition, intensive cleaning with strong alkaline (pH values 1 – 13) will not affect the quality of the CR membrane . The result is a longer service life and optimal filtration results.
