OCH 1401 – Polymer Based Hi Silica RO Antiscalant
RO ANTISCALANT OCH 1401
OCH 1401 Hi Silica RO Antiscalant is a premium polymer-based scale inhibitor developed by OCH Chemicals & Systems for reverse osmosis (RO) and nanofiltration (NF) systems operating with high-silica feed water. It is formulated to control silica scaling while also inhibiting calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate, calcium fluoride, and metal oxide deposits on membrane surfaces. The product is suitable for all polyamide RO membranes and supports higher recovery rates with reduced membrane cleaning.

Frequently Asked Questions
What is OCH 1401 used for?
OCH 1401 is used to prevent silica and inorganic scale formation in RO and NF membrane systems, particularly where feed water has high silica content.
Which scales does OCH 1401 control?
It controls silica, calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate, calcium fluoride, and metal oxide scales.
Is OCH 1401 suitable for all RO membranes?
Yes. It is compatible with all polyamide reverse osmosis and nanofiltration membranes.
What is the recommended dosage?
A typical dosage is 2–5 ppm, though 10–12 ppm may be required depending on silica concentration, TDS, hardness, recovery, and overall feed water quality.
What are the advantages of OCH 1401?
It reduces scaling, extends membrane life, lowers maintenance costs, improves recovery, and helps maintain consistent RO plant performance.
