The external principle
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.
Inside-Out Crossflow Filtration
Think Outside the Box
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.
The external configuration
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.
Outside-In Filtration
Higher fouling
Lower flux
Harder to clean
Inside-Out Filtration
Superior fouling resistance
Higher sustainable flux
Easier to clean
