🧪 RO Chemistry (Phosphonate Antiscalant 2-5 PPM, LSI & Silica Scaling Prevention)

RO Antiscalant Dosing Calculator

Calculate chemical antiscalant feed rates (PPM dosage and metering pump GPH) to prevent calcium carbonate, barium sulfate, and colloidal silica precipitation on RO membrane surfaces: calculate Langelier Saturation Index (LSI) and Stiff & Davis Stability Index (SDSI) across concentrate streams, extend membrane cleaning intervals, and water chemical supply margins.
