Ultrafiltration - Wikipedia

In order to increase the life-cycle of membrane filtration systems, energy efficient membranes are being developed in membrane bioreactor systems. Technology has been introduced which allows the power required to aerate the membrane for cleaning to be reduced whilst still maintaining a high flux level.

Basics of Ultrafiltration | Pureflow

This gives the UF a long service life, finer filtration, and much less maintenance than a replaceable filter element. Flux. UF modules are rated on the amount of permeate they can produce in gallons per square foot per day (gfd). This is known as flux. To size the module for a specific duty, the square feet of a membrane surface must also be known.

How to Calculate Percent Recovery and What Affects it in a ...

Apr 03, 2018 · It is important to design with a conservative flux rate, as an excessive flux rate will accelerate membrane fouling. An operator may be tempted to increase the membrane feed pressure to increase the permeate flow, but the flux rate will also increase and the system may become more prone to fouling and require chemical cleaning more frequently.

Filtration Processes | IWA Publishing

Filtration is a process that removes particles from suspension in water. Removal takes place by a number of mechanisms that include straining, flocculation, sedimentation and surface capture. Filters can be categorised by the main method of capture, i.e. exclusion of particles at the surface of the filter media i.e. straining, or deposition within the media i.e. in-depth
