High-silica antiscalant for RO/NF plants. Controls silica/silicate scaling, stabilizes flux, and reduces CIP frequency. Polyamide-compatible.

9+ High Silica RO Antiscalant is a specialized scale-inhibitor formulated to control silica and silicate deposition (including iron/ferric silicate) in RO/NF systems. Designed for high-silica borewell and industrial feed waters, it helps maintain permeate quality, keep ΔP in check, and extend time between CIP—when dosed correctly and used with proper pretreatment.

Why 9+ Hi-Silica works

• Targets polymerized silica and silicates that typical antiscalants struggle with.

• Performs across wide TDS and temperature ranges; polyamide-membrane compatible.

• Supports higher recovery with stable flux when paired with pH control and good pretreatment.

• Available from 10 ml single-dose pouches for trials to bulk packs for continuous operation.

Typical dosing

• Feed pH control often improves silica handling—aim pH 6.5–7.5 before RO.

• Starting dose: 4–8 ppm (mg/L, as supplied); adjust by monitoring ΔP, normalized permeate flow, and concentrate silica.

• Guide (concentrate silica):

  • ≤120 mg/L → 4–5 ppm

  • 120–180 mg/L → 5–7 ppm

  • 180–220 mg/L → 7–8 ppm

  • 220 mg/L → Consult 9+ tech support

• Pre-dilution: Add to clean water and feed via a dedicated dosing line on the RO feed.

• Do not mix with oxidants/biocides; ensure free chlorine <0.1 ppm before membranes.

Where to use
Municipal/industrial RO plants, packaged-water lines, and high-silica borewell applications. Industrial/process use only; not for domestic RO.

Safety
Use PPE (gloves/eye protection). See SDS for handling, storage, and first aid.
