BOP WATER FILTER CARTRIDGE

摘要

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 m2. 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.

主权项

1. A diatomite-based ceramic filter, said ceramic filter having:
a permeability of greater than about 0.5 Darcy; an abrasion mass loss value of less than about 25 mg/cm2; and wherein the diatomite-based ceramic filter reduces bacteria by greater than about 3-log.
