Think Outside the Box

The External Principle

At Berghof Membranes, we believe in external membrane filtration and the potential for innovation that drives us to “think outside the box” in creating tubular membrane solutions for wastewater treatment for industries around the world.

The Berghof Membranes filtration systems are positioned outside the bioreactor and utilize variable crossflow velocity to keep the membranes working at optimal conditions. If necessary, this process is supported with permeate backwash (temporarily reversed permeate flow) or chemical backwash protocols.

Tubular membrane filtration is frequently applied in the external configuration because of the greater ease in cleaning, zero odor emissions, and overall superior robustness.
