Advanced antiscalant for 6000 ppm sulphate and high TDS Water systems

High Sulphate RO Antiscalant is a premium-performance membrane treatment formulation specifically developed for reverse osmosis (RO) and nanofiltration (NF) systems operating with high-sulphate brackish water. The advanced formulation provides exceptional control of inorganic scale formation and particulate fouling, enabling high-recovery operation while maintaining membrane efficiency, stable permeate production, and extended membrane service life. The formulation utilizes a carefully balanced combination of high-performance phosphonate-based inhibitors, polymeric dispersants, threshold inhibitors, and crystal growth modifiers that effectively suppress the precipitation of calcium sulfate (CaSO₄), calcium carbonate (CaCO₃), barium sulfate (BaSO₄), strontium sulfate (SrSO₄), iron deposits, and colloidal foulants. It also provides excellent silica dispersion, helping reduce silica and silicate scaling under demanding high-recovery operating conditions. Designed for high-TDS feed water, the product maintains excellent chemical stability over a broad operating range and is fully compatible with all major polyamide RO and NF membrane types. The formulation minimizes scale formation on membrane surfaces, reduces differential pressure increase, extends cleaning-in-place (CIP) intervals, and helps maintain consistent permeate flow and salt rejection performance throughout extended operating cycles. This formulation belongs to the same functional class and chemical family as leading commercial high-sulphate RO antiscalants used worldwide. While not identical to proprietary products, it has been developed to provide comparable performance for controlling CaSO₄, CaCO₃, and high-TDS scaling when properly dosed and operated under recommended system conditions.
