RO Membrane Scale Inhibitor & Silica Antifoulant - ROCscale 91

Advanced Reverse Osmosis Technology

RO Membrane Scale Inhibitor - ROCscale 91 is an RO membrane scale inhibitor and has been developed specifically for use with high silica waters and is a synergistic blend of threshold antiscalants and dispersants.

Precipitation of scale on RO membranes will reduce system performance and lead to premature membrane replacement. Build-up of scale and deposits on RO membrane leads to poor permeate quality, low permeate production, unscheduled downtime, increased water consumption and increased energy costs.

ROCscale 91 allows plant operation with concentrate silica levels up to 230 mg/l at pH 7.5 and 30C. ROCscale 91 is not deactivated by the presence of iron or manganese and is an effective scale inhibitor against all insoluble calcium salts.
