Continuous Disinfection

Continuous Disinfection and Filtration of Microbiologically Contaminated Water ( Microbiological – bacteria, viruses, and protozoans)

Private Water systems, in Ohio, requiring continuous disinfection and protozoan cyst reduction are rainwater cisterns, springs, ponds, and some shallow wells.  Private water system ponds require additional continuous filtration equipment that includes either a rapid sand filter with coagulation and cyst reduction filters, or a rapid sand filter with a step filters arrangement. Slow filters may be used on pond systems without the additional of cyst filters since the slow sand filter design is intended to reduce cysts.
