RO Antiscalant for High Silica & Metal Oxides in US
Innova Corporate (India) is a specialized manufacturer and supplier of High Silica RO Antiscalants in US. Silica is one of the most difficult foulants to manage in any RO plant — it stays dissolved in the feed water and only polymerises into a hard, glass-like layer once it concentrates in the reject stream. Standard antiscalants designed for calcium and magnesium scale cannot stop that process, and once the silica layer sets, no acid or alkaline cleaner will fully remove it. The US has several regions where groundwater silica runs well above 30 ppm — the Southwest (Arizona, Nevada, Southern California), parts of West Texas, Utah, New Mexico and certain Midwest aquifers. For plants in these areas, a dedicated high silica antiscalant is not optional; it is what keeps the system running at design recovery.
Our High Silica RO Antiscalant in US is a targeted solution designed to control the deposition of inorganic scales and metal oxides in the same dosing program. It stabilises silica, keeps it in suspension, and prevents polymerisation on the membrane surface — while also sequestering iron and manganese that appear alongside silica in the same US groundwater. The formulation is engineered for feed water with an LSI up to +2.5, iron up to 1.5 ppm in reject, and silica levels up to 325 ppm (mg/L) in reject. That covers the worst-case conditions seen in Phoenix, Tucson, Las Vegas, Fresno, Bakersfield, El Paso and San Antonio municipal and industrial plants.
Key Features & Strategic Benefits in US:
- Critical Silica Control: Prevents complex silica-based scales that are often irreversible once they form on the membrane surface.
- Iron Fouling Sequestration: Effectively manages the high iron content common in many US aquifers to prevent red-brown membrane staining and ferric hydroxide deposits.
- Optimized Recovery: Allows for higher water recovery rates even with high TDS and elevated silica concentrations — the exact operating condition of most Southwest plants.
- Membrane Compatibility: Safe and compatible with all major brands of Polyamide, TFC and NF membranes used across the US.
- Environmentally Responsible: Completely organic and biodegradable formulation, keeping the discharge stream compliant with EPA and state discharge limits.
- Maintenance Reduction: Drastically reduces the frequency of chemical cleanings and element replacements for US plants, cutting both downtime and long-term operating cost.
Dosage & Application Guidelines for US:
High Silica RO Antiscalant should be dosed directly into the feed water line (after pretreatment). Standard dosage ranges from 2 ppm to 20 ppm, depending on Calcium Hardness, Iron, TDS and Silica content at your US facility:
- Moderate Hardness: 2-3 ppm is sufficient for alkalinity and hardness control.
- High Iron (0.5 - 1.0 ppm): Increase dosage by 5-7 ppm to effectively stabilize the system against iron-rich US groundwater, which is common in older Northeast and Midwest well supplies.
- Extreme Silica (Up to 325 ppm): A dosage of approximately 10-15 ppm is recommended for full inhibition in the reject stream — this covers the worst-case silica levels seen in Arizona, Nevada and Southern California feeds.
Storage & Handling: Store in original, tightly sealed containers in a cool and dry environment at your US site. Keep away from direct heat and sunlight.
