Electric Field-Assisted Cross Flow Cells
Electric Field-Assisted Cross Flow Cells are bench-scale cross/tangential flow membrane test cells used in membrane separation processes.
Applying an electric field to membranes enhances membrane performance by increasing electrostatic repulsion between membranes and foulants. This is possible because most membrane foulants including sludge flocs, soluble microbial products (SMP) and extracellular polymeric substances (EPS) are generally negatively charged.
Sterlitech cross flow cells mimic hydrodynamic conditions present in real size systems. In real size systems, electric field can be applied in tubular, flat sheet or spiral wound modules.

Frequently Asked Questions
Q: Why is the flat sheet membrane I'm using measuring a flux value less than the published flux value?
Flow characteristics for a spiral element and flat sheet membrane are significantly different and are really only comparable on a qualitative basis. Variability in the membrane manufacturing process, differences in water composition, test procedures, and test equipment, used in a factory, laboratory, or elsewhere, will impact water flux results.
