Filtration Filter Effluent Control

Most drinking water plants combine a conventional gravity-fed filtration system with a means for disinfection as part of the water treatment process. As the last stage of particle removal prior to disinfection, filtration plays a critical role in assuring safe water quality, given that many pathogens can escape common methods of disinfection under the cover of particle-filled water. Filter performance is evaluated based on turbidity, which effectively uses the clarity of liquid to indicate the amount of particulate present in the water.
