Silica Antiscalant (High pH) for High-TDS & High-Recovery RO Systems
Innova Corporate (India) is a specialised manufacturer, bulk supplier, and global exporter of High pH Silica Antiscalants, headquartered in Delhi. We serve a wide network of clients throughout India while extending our supply chain to the Middle East, Africa, and Southeast Asia. Silica fouling is one of the most severe challenges in RO operations — it forms a hard, glass-like scale that is nearly impossible to remove. Our advanced alkaline formulation is specifically engineered to inhibit silica precipitation, ensuring smooth operation even in water with high reactive silica content.
Our Silica Antiscalant is a high-performance alkaline product that is fully compatible with drinking water systems. By keeping silica in suspension, it prevents membrane plugging, reduces the frequency of chemical cleanings (CIP), and significantly extends the operational life of your RO membranes. This translates into lower maintenance costs, reduced downtime, and higher plant availability.
Unlike conventional antiscalants, our high-pH silica formulation is engineered to remain stable across the alkaline pH range where reactive silica is most likely to polymerise and deposit. It effectively controls silica levels up to 200 ppm in concentrate, making it an ideal choice for challenging Indian groundwater, borewell, and surface water applications.
Key Features & Strategic Advantages:
- Superior Silica Control: Effectively manages high levels of reactive silica in feed water — up to 200 ppm in concentrate.
- Membrane Protection: Prevents irreversible physical damage caused by sharp, glass-like silica crystals.
- Drinking Water Safe: Formulated with ingredients suitable for potable water applications, complying with health and safety standards.
- Cost-Efficiency: Minimises downtime and reduces the need for expensive silica-specific cleaning cycles.
- High pH Stability: Maintains performance across a wide alkaline pH range (9–11) where silica is most problematic.
- Universal Membrane Compatibility: Safe for use with all leading RO membrane brands including Dow FilmTec, Hydranautics, Toray, and LG.
- Broad-Spectrum Scale Control: In addition to silica, controls calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate, and iron-based scales.
- Extended Cleaning Intervals: Significantly stretches the time between CIP cycles, reducing downtime, labour, and chemical consumption.
- Flexible Dosing: Can be dosed neat (concentrated) or pre-diluted depending on dosing pump capacity and system design.
- Cost-Efficient Formulation: Premium performance at a competitive per-litre cost with a fast return on investment.

Frequently Asked Questions (FAQ)
| Q1. What is a Silica Antiscalant High pH? | A Silica Antiscalant High pH is a specialised liquid chemical dosed into RO feedwater to prevent the precipitation of reactive silica and other sparingly soluble salts on reverse osmosis membrane surfaces, especially in high-pH and high-TDS water conditions. |
| Q2. Why is silica scaling so difficult to remove? | Silica scale is extremely hard, glass-like, and resistant to standard acid or alkaline cleaning. Once it forms, it is nearly impossible to remove without damaging the membrane. Prevention through a high-performance silica antiscalant is the only practical solution. |
| Q3. What is the recommended dosage of Silica Antiscalant High pH? | The typical dosage ranges from 2 to 10 ppm in RO feedwater, going up to 15 ppm in severe conditions. The exact dose depends on feedwater silica concentration, pH, temperature, and recovery rate. |
| Q4. Which scales does this antiscalant control? | Our Silica Antiscalant High pH effectively controls reactive silica, calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate, calcium fluoride, iron, and metal oxide scales commonly found in high-TDS industrial RO systems. |
| Q5. Is this antiscalant safe for drinking water plants? | Yes. Our Silica Antiscalant High pH formulation is certified and classified as safe for use in systems producing potable or drinking water, complying with industry-recognised health and safety standards. |
| Q6. Can this antiscalant replace a water softener? | Yes. Our Silica Antiscalant High pH acts as a highly efficient, low-maintenance alternative to traditional softener filters. It eliminates the need for regeneration salt, brine discharge, and frequent resin replacement. |
| Q7. Which RO membranes are compatible with this antiscalant? | Our Silica Antiscalant High pH is fully compatible with all leading RO membrane brands including Dow FilmTec, Hydranautics, Toray, and LG, as well as downstream coagulants, biocides, and cleaning chemicals. |
| Q8. What is the pH range this antiscalant works in? | Our Silica Antiscalant is specifically designed to remain stable and effective across high pH ranges (typically pH 9 to 11), where reactive silica is most likely to precipitate in RO systems. |
| Q9. What is the shelf life of Silica Antiscalant High pH? | The product has a shelf life of 24 months from the date of manufacturing when stored in its original sealed container at temperatures between 5°C and 40°C, away from direct sunlight. |
