MetaGuard contains no phosphates or phosphate derivatives. This unique attribute allows it to perform without contributing to metal precipitation on the membranes. It will not cause biological growth in tanks, piping, or the RO. MetaGuard is typically dosed into feedwaters at the rate of 2-6 ppm of the liquid mixture and it may be injected from the same tank as BioGuard ACS™ anti-microbiological pretreatment.
MetaGuard powder is compliant with ANSI/NSF Standard 60 requirements and may be used on potable water systems.
