Four groundwater treatment plants have been operating, two use air stripping, one the Advanced Oxidation Process, and the fourth uses an activated carbon filter.

There are five types of water-treatment units available : physical filters, activated carbon filters, reverse osmosis ( RO ) filters, distillation units and ultraviolet ( UV ) disinfection units.

This problem is most often addressed through two filtration solutions : Activated carbon filters absorb nitrogen compounds and other toxins, while biological filters provide a medium designed to enhance bacterial colonization.

Simple procedures such as boiling or the use of a household activated carbon filter are not sufficient for treating all the possible contaminants that may be present in water from an unknown source.
15.
Granulated activated carbon filters typically remove chlorine and lead from water, while carbon block filters absorb additional impurities that include metals, chemicals, parasites and e-coli _ as long as filters are changed regularly.
16.
Activated carbon filters are used to retain radioactive gases within the air vacuumed from a nuclear boiling water reactor turbine condenser . The large charcoal beds adsorb these gases and retain them while they rapidly decay to non-radioactive solid species.
17.
There are models that have a heating element which blows warm air to dry the user after washing, that offer heated seats, wireless remote controls, illumination through built in night lights, or built in deodorizers and activated carbon filters to remove odors.
