Abstract: Certain embodiments provide a water quality improving filtration system. The filtration system includes a water filter having a water impermeable barrier. The water impermeable barrier defines a pooling volume. An inlet is in fluid communication with the water impermeable barrier and conducts water to the pooling volume. The pooling volume includes a quantity of fluidizable filtering media which includes a bimetallic substance. The water filter includes a block of adsorption material that is located in the interior of the water filter, as compared to the pooling volume. The block of adsorption material defines a cavity. A water outlet is in fluid communication with the cavity and conducts water from the water filter. The water impermeable barrier, pooling volume, and fluidizable filtering media cooperate to form a fluidized bed of filtering media.

Abstract: A filtration apparatus for water allows facile purification of water used, for example, for domestic housing, swimming pools and hot tubs.

Abstract: Water purification is achieved by contacting the water with a container of charcoal, zeolite and a bimetallic alloy. In a preferred embodiment, the three components are segregated from each other and contained in a bag having three compartments.
