Tubular UF Membrane Modules
To prevent fouling and clogging, Berghof Membranes developed its line of robust tubular UF membranes based on inside-out crossflow filtration. This means more fouling-resistant membranes that are ideal for the separation and filtration of challenging industrial effluent and wastewater.
Unlike outside-in filtration, as seen with submerged membrane technology, our robust tubular UF membranes enable operators to sustain higher flux rates with less frequent cleanings and reduced maintenance.
Tubular UF membranes from Berghof Membranes are made from low-fouling PVDF, PES and chemical–resistant polymers cast onto dual support layers. In addition, our unique module assembling process ensures straight end-to-end membrane tube configurations.
We offer various configurations and options to choose from:
- Non-backwashable membranes
- Backwashable membranes requiring less chemical usage
- Various tube diameters and cut–offs
- GRP or PVC module housings
These membranes are manufactured in our fully-automated production facility, equipped with state-of-the-art photo imaging inspection systems to ensure membrane quality and integrity.
Outside In Filtration
- Higher fouling
- Lower flux
- Hard to clean
Inside Out Filtration
- Superior fouling resistance
- Higher sustainable flux
- Easier to clean
Advantages of Tubular UF
- Reduced membrane fouling due to crossflow filtration
- Higher flux and output
- High quality permeate ideal as pretreated feed for RO systems
- Less frequent cleaning resulting in reduced chemical costs
- Decrease in system downtime
- More robust membranes that are less susceptible to breakage
5 mm Membranes
The 5 mm UF membranes from Berghof Membranes are excellent in treating low-strength wastewater and effluent streams that contain a low amount of solids, such as in water reuse applications. The smaller inner diameter of the 5 mm membrane tubes means more membranes can be packaged into a membrane module.
Greater packing density means a larger membrane area can be achieved with fewer modules, enabling plant designs with smaller footprints that still achieve the desired flux.
8 mm Membranes
The degrading, recycling, and reuse of wastewater that contains high amounts of solids can be a real challenge for wastewater treatment plants. The 8 mm inner diameter of our high-solids tubular membranes make them ideally suited for high-strength wastewaters and effluent streams while maintaining superior fouling resistance. Applications such as landfill leachate or treatment of industrial wastewater containing oils, metals, or high COD concentration.
Chemical Resistant Membranes
The superior robustness of Berghof’s CR membranes enable them to exhibit impressive resistance to a wide variety of chemicals and pH values (2–12), meaning that our CR membranes are ideally suited for applications with high-strength wastewater or process streams, such as RO concentrate/brine. In addition, our CR membranes can withstand intensive cleaning with strong alkaline, thus enabling longer service life.
