SpectraGuard™ 360

SpectraGuard™ 360, developed by PWT (USA), is a high-performance antiscalant/dispersant specifically formulated to support stable, long-term operation of reverse osmosis (RO) systems. By effectively managing feedwater chemistry, it prevents the formation and deposition of carbonates, sulfates, phosphates, metal hydroxides, and silica. SpectraGuard™ 360 ensures reliable membrane protection across a wide range of water qualities.

Brand: PWT

Product Type: Antiscalants

Product features

Controls scaling from CaCO3, CaSO4, BaSO4, SrSO4, Ca3(PO4)2, CaF2, silica, and hydroxides of Fe, Mg, and Al.
