WATER TREATMENT, COMBINED TECHNIQUE

A relatively new water disinfection technique greatly reducing the need for chlorination while effectively destroying up to 99.9 percent of coliphage (intestinal bacteria) in raw water. The method combines two purification techniques that have been previously used separately for water purification: potassium permanganate and copper/silver ions: but in combination the processes kill bacteria up to 10 times faster than metal ions alone and up to 5 times faster than potassium permanganate alone.
