SpectraGuard™
SpectraGuard SC™ Liquid Super Concentrate
SpectraGuard liquid antiscalant/dispersant is a high-performance chemical pretreatment that controls inorganic scale, metals and colloids in RO feedwaters. Its unique performance characteristics provide users with complete control over system feedwater chemistry, while reducing membrane scaling tendencies and minimizing membrane cleaning requirements. SpectraGuard is compatible with all membrane types and system components.
SpectraGuard SC is a liquid super-concentrate which provides users the convenience of a 5 gallon (18.9 liter) pail equivalent to a 55 gallon (208.2 liter) drum of standard liquid antiscalant. SpectraGuard SC cuts shipping volume by 90% making it ideal for high-volume users.
SpectraGuard and SpectraGuard SC maintain performance integrity at extreme pH levels and temperatures. These products remain stable in the presence of multivalent ions such as iron. All SpectraGuard products are phosphate-free, and do not contribute to metal precipitation or biological growth in tanks, piping, or the RO.
SpectraGuard is typically dosed into feedwaters at the rate of 2-6 ppm and it may be blended with PWT’s BioGuard ACS™ and OrganoGuard™ products. 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.
Both SpectraGuard and SpectraGuard SC comply with ANSI/NSF Standard 60 requirements and may be used on potable water systems.
