Commercial RO Antiscalant Liquid Supplier — Gujarat

RO antiscalant from Drashti Chemicals protects membranes at pharma, beverage, and boiler-feed RO plants across Gujarat where groundwater hardness runs 400–800 ppm TDS. Without antiscalant, calcium carbonate and silica scale blind membrane elements within weeks — CIP frequency doubles, permeate flow drops 15%, and element replacement accelerates. A continuous dose of 3–5 mg/L antiscalant typically extends membrane life from 2 years to 4+ at fraction of element cost.

Antiscalant chemistry splits into phosphonate-based (broad spectrum, handles CaCO₃ and BaSO₄) and polymer-only (silica-specific, low-phosphate discharge plants). Select phosphonate blend when feed water LSI exceeds +1.5; select silica-specific when SiO₂ exceeds 120 ppm in concentrate. Drashti supplies both — provide your latest water analysis (Ca, Mg, alkalinity, SiO₂, pH, recovery %) and we match grade. COA confirms active content and pH.

Dosing point is post-cartridge filter, pre-RO high-pressure pump — never dose into raw water before softener if you run ion exchange upstream. Meter via solenoid pump tied to feed-flow proportional signal. Shock-dosing after CIP is wrong practice; maintain steady 3–5 mg/L. Overdose above 8 mg/L can foul membranes with polymer film — if ΔP rises within 48 hours of antiscalant change, check dose calibration.

Packaging: 20 kg HDPE carboys, 200 kg drums, and 1000 kg IBC totes. MOQ one carboy for pilot RO skid; bulk quote on request for multi-train plants in Dahej and Panoli. MSDS and COA included. Store 5–35 °C away from sunlight. Drashti Vadodara ships same-week across Gujarat; GST 24AGLPC6288M1ZX on all invoices.

Antiscalant vs. softener-only pretreatment: softener removes hardness but not silica or sulfate scale — antiscalant handles concentrate-side scaling at 4:1 recovery where softener alone fails. Antiscalant vs. acid dosing: acid controls LSI but corrodes steel and adds chloride; antiscalant is non-corrosive at effective dose. For ZLD RO trains, pair antiscalant with high-pH silica dispersant grade — ask Drashti for ZLD-specific blend.
