We at Berghof Membranes believe in external side stream membrane filtration and it is the passion that drives us to “think outside the box” of membrane technology for wastewater treatment. In tubular membrane filtration systems are placed OUTSIDE the feed tank or bioreactor, thereby resolving the inherent problems with many applied technologies.
To drastically minimize membrane fouling and clogging, Berghof Membranes developed its line of robust external membrane systems based on INSIDE-OUT crossflow filtration. This means superb fouling resistance and control, ideal for the separation and filtration of challenging industrial effluent and wastewater. As result, our robust filtration systems enable operators to sustain higher flux rates with less frequent cleanings and reduced maintenance.
External tubular membrane filtration present significant advantages for industrial treatment plants which are subject to varying processes- and waste streams. The ability to control crossflow velocity, results in a significant reduction of energy consumption, fouling potential and operating costs.
To prevent fouling and clogging, Berghof Membranes developed its robust tubular UF membranes based on cross-flow filtration technology (inside-out filtration), resulting in more fouling-resistant membranes that are ideal for the separation and filtration of challenging industrial effluent and wastewater.
Unlike dead-end filtration (outside-in filtration), as seen with conventional submerged membrane technology, crossflow filtration allows operators to sustain higher flux rates with less frequent cleanings and reduced maintenance.
Tubular UF membranes are also available in back-washable configurations that require less chemical usage and system downtime, thus extending the life of the membrane.

Higher fouling
Lower flux
Harder to clean

Superior fouling resistance
Higher sustainable flux
Easier to clean
Berghof Membranes developed the B-SMART® intelligent software platform to further assist our OEM partners in offering unique and advanced solutions to their customers.
In a tubular UF application, fluids flow through modules at a high velocity, sufficient to maintain a turbulent flow. At a typical TMP of 1 – 3 bar, the permeate stream is forced through the pores of the membrane while suspended particles remain in the retentate stream.High cross-flow on the membrane´s surface prevents the build-up of particles on the inner surface of the tube, ensuring high flux and prolonged membrane lifetime.
Contact us and learn moreOur intelligent technology enables several cleaning procedures to automatically remove membrane fouling. The combination of variable crossflow velocity, backwashing, chemical enhanced backwash and CIP makes our technology a revolutionary solution for the treatment of any effluent.
How it worksOur well-established crossflow filtration technology keeps the membranes working at optimal conditions. The combination of intelligent soft- and hardware, continuously analyses the situation and responds automatically to varying conditions whenever this is required.
Learn more about our Smart UF SkidsCleaning of wastewater systems with chemicals that contain high pH values, produces the best results. A major disadvantage is that polymeric membranes are not resistant to highly concentrated alkaline detergents. With this in mind, we developed the Chemical Resistant (CR) membrane, which are resistance to a wide variety of chemicals and pH values (2-12).
