Reverse Osmosis Scale Control

Reverse Osmosis Scale Control

CES offer a full range of proven products for scale control in membrane applications. These customized products are offered under our VERSATREAT Series product line and are designed to provide outstanding performance for severe service and general purpose applications including the control of CaCO„ CaSO„ BaSO„ calcium phosphates, heavy metals, silica and silicatcs.Thc key to good RO operation is a well maintained pretreatment system. For example, all media filters should be clean and free of channeling.

Residual flocculants and/or coagulants from upstream treatment (cationic molecules or polyelectrolytes) can cause problems when they combine with polymeric antiscalants (anionic molecules). Avoid this problem by keeping the media filters in good condition and not overfeeding the flocculants coagulants.
Antiscalant should be dosed upstream of the RO, typically before the cartridge filters. This assures adequate mixing of the antiscalant prior to entering the RO
