SpectraGuard™ 250
SpectraGuard™ 250, developed by PWT (USA), is a specialized antiscalant/dispersant formulated to prevent scale formation on RO membranes effectively. Its advanced phosphate-based composition enhances control over scale-forming compounds, including carbonates, sulfates, and metal hydroxides. By preventing scaling, SpectraGuard™ 250 optimizes RO system efficiency, extends membrane lifespan, and reduces overall operational costs.
Product features
- Effectively prevents scaling caused by CaCO3, CaSO4, BaSO4, SrSO4, Ca3(PO4)2, CaF2, silica, and Fe/Mg/Al hydroxides.
- Formulated with phosphate-based compounds, making it compatible with cationic polymers — ideal for RO systems utilizing cationic polymer pre-treatment.
- Stable in chlorine-rich environments, making it suitable for feedwater sources containing halogens.
- Operates efficiently across a broad pH range, minimizing the need for pH adjustments.
- Compatible with feedwater containing metal oxides, preventing precipitation issues.
- NSF/ANSI 60 certified, guaranteeing safety for food and drinking water applications.
