BOP WATER FILTER CARTRIDGE
A water filter may include a diatomite-based ceramic filter having a median pore size greater than about 5 microns, and at least one of a halogen source, a UV source, an active carbon source, or a filtration membrane. A method of filtering water includes passing water from a source chamber through a diatomite-based ceramic filter having a median pore size greater than about 5 microns, and passing the water through at least one of a halogen source, an active carbon source, a UV source, or a filtration membrane to a collection chamber. The diatomite-based ceramic filter may further include bentonite. The water filter may include a biocide. The water filter may have a flow rate greater than about 5 L/hr when normalized to a surface area of 0.015 m 2 . The water filter may reduce bacteria by greater than about 6-log. The halogen source may include a halogen elution system or a surface modification of the diatomite-based ceramic filter.
