Innova Corporate (India) offers an Antiscalant for High Sulphate Water designed for Dubai's industrial sites where brackish groundwater or industrial discharge contains elevated sulfate levels (600-2000 ppm) due to natural gypsum deposits or seawater intrusion. High sulfate combined with calcium leads to gypsum (CaSO₄·2H₂O) scale which is extremely hard to remove. Our antiscalant uses advanced polyacrylate-sulfonate copolymers (AA/AMPS) and PCA (phosphino-carboxylic acid) technology to disrupt sulfate crystal nucleation and growth. For Dubai's aluminium smelters (EGA/DUBAL), district cooling plants, and chemical units, cooling towers and RO systems facing sulfate scaling – our antiscalant prevents scale even at 120% supersaturation of CaSO₄. For ZLD systems (increasingly required by Dubai Municipality for industrial clusters), this antiscalant enables recovery ratios >85% without sulfate scaling, reducing evaporation load. Dosage: 4-10 ppm, effective up to 80°C (176°F). Unlike conventional antiscalants, our formulation does not precipitate with ferric or aluminum coagulants commonly used in Dubai's effluent treatment plants (ETPs). It also disperses clay and silt from stormwater runoff. Available in 25L, 200L drums. We provide on-site scale prediction using OLI or ScaleSoft software for optimal dosing. Compatible with all common biocides and corrosion inhibitors. For metal finishing and electronics effluents (in Dubai Silicon Oasis), we offer a low-phosphorus variant.
In calculating the dose rate of INNOVA MT 065 for facilities in Dubai, 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 Dubai 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 Dubai 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 Dubai, 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.
