Innova Corporate (India) introduces Antiscalant for High Sulphate Water for Lucknow. Sulfate levels (100-300 ppm as SO₄²⁻) come from groundwater, chemical plants, and textile units. High sulfate leads to calcium sulfate (gypsum) scale, which is difficult to control and tenacious on RO membranes. Our product is a polymer-phosphonate blend with sulfonated copolymers preventing calcium sulfate, barium sulfate, and strontium sulfate scales through crystal modification. Effective in cooling towers, RO systems, and ZLD evaporators serving textile (Chikan units), automobile ancillaries, chemical plants, and pharmaceutical units. Liquid, easy to dose at 3-10 ppm, effective up to 95°C. By using our product, Lucknow facilities achieve reduced scaling, 25-35% longer run times, lower cleaning costs, improved water recovery (85-90%), and UPPCB compliance for Gomti river protection.
In calculating the dose rate of INNOVA MT 065 for facilities in Lucknow, the membrane manufacturer's operating limits and local feed water quality should be strictly considered. All dose rate calculations should be made on the computer projection programme "e-WATER 5.0", which calculates the Ipb/Ksp ratio for calcium sulphate and other potential scaling salts specific to the Lucknow water table.
For Ipb/Ksp ratios < 3 the preferred product of choice is Tacelene Chem-7065; for ratios 2.8 to 7.0, INNOVA MT 065 is normally dosed at 5.0 to 25 mg/L in the concentrate, which is equivalent to 2.5 to 6 mg/L in the feed water for Lucknow based systems, dependent on the system recovery.
INNOVA MT 065 can be diluted with product water and should be applied continuously by means of a suitable metering pump. For the tea processing and rubber industries in Lucknow, continuous feed is essential since calcium sulphate is difficult to remove once precipitation has occurred in local filtration units.
INNOVA MT 065 has been developed specially as a calcium sulphate inhibitor, for waters with CaSO4 Ipb/Ksp ratio of 2.8 to 7.0. It functions by a powerful threshold mechanism of calcium carbonate, and is highly tolerant to the presence of iron.
