PHIX™ Media acid neutralization systems feature innovative technology to lower wastewater pH before it enters the plumbing system and sanitary sewer. Need a better quality acid neutralization tank? Compared to acid neutralization systems that use limestone, granular PHIX Media has 5 times the neutralization power and 30 times the service life. PHIX systems have been specifically engineered to deliver maximum performance from directly under the sink in institutional and commercial settings such as schools, labs and hospitals. And when larger, multi-sink configurations are required, PHIX Gravity systems are the ideal choice to neutralize acidic waste water
