Antiscalant chemicals are used to prevent the scaling & fouling of the RO membranes. Scale may consist of mineral fouling such as calcium sulfate, calcium carbonate, barium sulfate, silica, calcium fluoride, and strontium sulfate. The MemGuard MG pretreatment program is designed to significantly reduce scale formation and fouling in membrane systems. The antiscalants are suitable and effectively used in a range of feedwater sources, including brackish, waste and seawater.

MemGuard MG series comply with NSF/ANSI/CAN 60: Drinking Water Treatment Chemicals – Health Effects by most governmental agencies that regulate drinking water supplies.
