DEQUEST® SPE is a multifunctional antiscalant for Reverse Osmosis (RO), nanofiltration (NF) and Electro-dialysis Reversal (EDR) systems. It is highly effective in preventing calcium carbonate scale on membrane surfaces. Besides its excellent calcium carbonate scale inhibition DEQUEST® SPE is effectively controlling calcium sulphate, calcium fluoride and metal oxides scale. DEQUEST® SPE has approvals from major membrane manufacturers. DEQUEST® SPE is certified to ANSI/NSF Standard 60 for the production of potable water by reverse osmosis, nanofiltration and EDR systems.
Application
The dosage level of DEQUEST® SPE is dependent on the quality of the feedwater and the saturation indices of the various scales forming species present in the concentrated brine. Recommended injection point is into the feedwater, downstream of any filtration equipment and cartridge filters.
