The Sanitizer-Plus from Water-Right Inc. is effective in treating hard water with high amounts of iron bacteria and hydrogen sulfide (<1.0 ppm). The performance of this system comes from a media configuration using the Sanitizer's silica-based Crystal-Right media, capable of softening and removing high amounts of iron and manganese, and a heavier Min-Plus media known for its ability to treat hydrogen sulfide and iron bacteria. Both media are impervious to free chlorine produced by Sanitizer's in-line chlorine generator. Free chlorine is used to clean and safely disinfect the entire media bed with each regeneration eliminating iron bacteria and its associated odors. Water-Right Inc.
