POTABLE WATER PURIFICATION PROCESS INCLUDING BIOFILTRATION

摘要

An improved bio-filter system is presented for purifying potable water comprising locating at least one bio-filter structure upstream of a disinfecting unit in a potable water purifying plant and colonizing fermentation-raised bacteria on or within the at least one bio-filter structure and including the at least one bio-filter structure having the fermentation-raised bacteria. Improved potable water treatment processes are presented comprising the elimination of oxidation/disinfection prior to coagulation. Improved potable water treatment processes are presented utilizing oxidation/disinfection with ozone in the purifying process upstream of bio-filtration. Biofiltration is then followed by final filtration and final disinfection. By utilizing a new coagulation technology, separation of solids (including TOC and Dissolved organic carbon) from potable water is improved. This new coagulation technology is preferred to be used along with ozonation upstream of bio-filter(s) colonized with fermentation-raised non-ubiquitous bacteria. This new coagulation technology is most preferred to be used with the new bio-filter(s) colonized with fermentation-raised non-ubiquitous bacteria; this combination can replace ozonation.
