Abstract: Disclosed is a gravity fed purification system having a purification media having a layer of low ash catalytic carbon having a nominal particle size range of about 20 mesh to about 50 mesh, wherein the purification system is able to produce a flow rate of about 1000 to about 1500 cc/min with a pressure head of about 300 to about 350 cc.

Abstract: This invention relates to a modular purification system having a disposable sump assembly and an improved flow distribution plate. The system is readily adaptable to a variety of configurations without the need for repiping or replumbing of the installation, and lends itself to the use of multiple purification techniques.

Abstract: A flow connector adapted to connect a lug-type filtration sump to a screw-type filtration head, having a first portion for receiving a lug-type filtration sump, and a second portion receivable by a screw-type filtration head.

Abstract: The invention relates to a two-stage design for a water purification system, with water to be purified first passing through a first stage containing particulate filtration media, and a second stage containing a porous filtration block. The particulate filtration media can be the same as, or different from, material included in the porous block. Either material may be any material that removes contaminants from water by, e.g., absorption, adsorption, ion exchange, sequestration, or other mechanism, or any combination of these.

Abstract: The invention relates to filtration media having nanocrystals of metal oxides, encapsulated in or impregnated into a binder matrix, which binds together particles of activated carbon. The filtration media can be compressed into a filtration block, has low pressure drop, and has excellent microbial removal properties.

Abstract: The invention, in its various embodiments, relates to a medium for purifying fluids, particularly consumable fluids like air and water, by removing organic materials from the fluids by contacting the fluids with a combination of extremely small diameter transition metal oxide and an aluminosilicate having relatively large pores. In addition, contact of the fluids with the purification medium can also significantly reduce the level of microorganisms existing in the fluid, providing another purification benefit.
