TEP Fouling in RO Membranes
We have a transparent exopolymer particles (TEP) fouling problem in our reverse osmosis (RO) membranes.
Our pretreatment includes dissolved air flotation (DAF) and ultrafiltration (UF).
Turbidity and silt density index (SDI) is normal in RO feed water but fouling still occurs.
How can we prevent TEP fouling in RO membranes?
