RO Pretreatment
Clarification Ahead of Reverse Osmosis
Plate settler clarification reduces the silt density index and fouling potential of RO feed water, protecting membranes and improving recovery.
RO Pretreatment
Reverse osmosis membranes require feed water with very low suspended solids and silt density index (SDI). Particulate and colloidal fouling causes flux decline, higher pressures, and shortened membrane life.
A plate settler stage — combined with coagulation where needed — removes suspended and colloidal solids before RO, lowering SDI and stabilizing feed quality. This is especially valuable for reuse and challenging surface-water sources.
Reliable RO pretreatment reduces cleaning-in-place frequency, protects recovery rates, and lowers the overall cost of producing high-quality permeate.
