Filtration

Filtration

Filtration is a physical process that occurs when liquids, gases, dissolved matter, or suspended matter adhere to the surface of, or within the pores of, an absorbent medium. The filtration of contaminants depends on the amount of contaminant present, as well as its size and charge. According to the Centers for Disease Control and Prevention (CDC), filtration following treatment with activated carbon, pH adjustment, chlorine, or other pre-treatment processes may extend the life of the filter’s absorbent membrane and its effectiveness in removing protozoa, such as Cryptosporidium and Giardia. It should also be noted that filtration has moderate effectiveness in removing bacteria, including Campylobacter, Salmonella, Shigella, and E. Coli, but is not effective in removing viruses or chemicals. Integra Environmental recommends microfiltration in conjunction with other water treatment systems.
