Spectraguard™ 111 RO Pre-Treament
SpectraGuard 111 liquid anti-scalant/dispersant is a highperformance chemical pretreatment that controls inorganic scale,
metals and colloids in RO feed waters. Its unique performance
characteristics provide users with complete control over system
feed water chemistry, while reducing membrane scaling tendencies and minimizing membrane cleaning
requirements. SpectraGuard is compatible with all membrane types and system components.
SpectraGuard maintains performance integrity at extreme pH levels and temperatures. These products
remain stable in the presence of multivalent ions such as iron. All SpectraGuard is phosphate-free, and does
not contribute to metal precipitation or biological growth in tanks, piping, or the RO.
SpectraGuard is typically dosed into feed waters at the rate of 2-6 ppm. As a liquid,
SpectraGuard is ready to use and may be injected neat, or diluted to accommodate varying
system sizes. SpectraGuard is available in 5 gallon (18.9 liter) pails, 55 gallon (208.2 liter)
drums, totes, and in bulk.
Classified for use in membrane systems producing drinking water (ANSI/NSF Standard 60).
