Sand filtration filtering system using ozone |
| abstract |
A device for filtering and disinfecting a fluid, such as waste water, is provided. The device includes a housing having an interior and a fluid inlet conduit in flow communication with the interior of the housing. An ozone source is in flow communication with the interior of the housing. Additionally, a method of filtering and disinfecting a fluid is provided. Filter media is introduced into a housing to form a filter bed. The fluid to be filtered is directed into the housing such that the fluid flows through the filter media to form a filtrate. Ozone us directed into the housing such that the ozone contacts and disinfects the filter media and the filtrate. |
