Critical (or threshold) flux is the highest flux when no or negligible fouling occurs, a concept first proposed in 1995.
The application of critical flux to inorganic fouling is well documented.
CMS and its research partners have identified similar trends in the onset of organic fouling.
CMS’s technology allows critical flux to be determined in real-time.
Fouling dramatically increases if a system is operated beyond the optimum recovery rate/critical flux: accelerated particle deposition sets in, eventually leading to the formation of cake or tight fouling layer. Once cake or fouling forms, the effectiveness of crossflow decreases and fouling accelerates.
The ability to identify critical flux allows RO facilities to operate at the recovery rate that delivers the optimum balance between minimisation of fouling and maximisation of permeate volume produced per unit of energy consumed.
CMS’s Service allows a plant to be operated at maximum recovery rate with any increase in fouling immediately identified.
