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.

• Transmembrane pressure [kPa]: -60 to +600

• pH range: 1 – 13

• Membrane Diameters: 5, 8, 12.7 mm

• Membrane area: from 2.1 up to 71.1 m²

• Module diameters available: in 3, 4, 6, 8 and 10 inch

• Module lengths: 1.5, 3, 4 m

Traditional wastewater treatment systems rely heavily on Clean-In-Place (CIP) protocols using relatively large quantities of chemicals which are costly and require operational shut-downs. Backwashable membranes, when used in combination with the intelligent software technology by Berghof Membranes, allow the wastewater system to operate at a lower velocity, thus consuming less energy. During the backwash, in which clean water is pushed outside-in, fouling is removed from the membranes module by module. Therefore, the system continues to produce permeate during backwash because the backwash procedure is performed sequentially by the module. If backwash with permeate doesn’t eliminate fouling, the intelligent software will automatically initiate a chemical-enhanced backwash (CEB).

• Transmembrane pressure [kPa]: -60 to +800

• pH range: 2 – 11

• Membrane Diameters: 5, 8, 12.7 mm

• Membrane area: from 2.1 up to 71.1 m²

• Module diameters available: in 3, 4, 6, 8 and 10 inch

• Module lengths: 1.5, 3, 4 m

For crossflow filtration applications with high-strength wastewater, high crossflow velocity and pressure rates, our non-backwashable membranes are the ideal choices. Our membrane durability and excellent fouling resistance ensure long membrane life and optimal membrane performance.

• Transmembrane pressure [kPa]: -20 to +800

• pH range: 2 – 11

• Membrane Diameters: 5, 8, 12.7 mm

• Membrane area: from 2.1 up to 71.1 m²

• Module diameters available: in 3, 4, 6, 8 and 10 inch

• Module lengths: 1.5, 3, 4 m

B-SMART® is a proprietary platform, designed specifically for our OEM partners that delivers complete and modular systems to solve the challenges in the treatment of industrial streams/effluent. Plant owners are looking for cost-effective and reliable solutions that can support industrial growth. Plant operators want easy-to-maintain systems that can meet strict discharge standards. B-SMART® helps OEMs to deliver both. Available in multiple configurations and with various functionalities, each B-SMART® system is expertly engineered with unique features and advantages to provide the flexibility, adaptability, and reliability you and your customers want.

Our containerized pilot units are plug-and-play and feature standardized but flexible software, allowing them to be customized to your filtration challenge. They have been designed to be flexible with the aim of coping with a broad range of wastewater characteristics and operational conditions: several membrane types, filtration parameters, and flow capacities can be very easily implemented.  The pilot units of Berghof Membranes are stand-alone and easy to connect, preventing extensive capital investments required. The pilots are automated for continuous operation, with fully safe operation and online monitoring.

The B-CARE® program from Berghof Membranes is an end-to-end comprehensive program developed to support our OEM partners from the piloting and engineering phase to operational system monitoring. Because process streams and wastewater can vary significantly, there is no typical or standard wastewater treatment solution.
