US 2026/0265087 A1 · PORTABLE APPARATUS AND METHOD FOR PURIFYING WATER FOR DRINKING FROM SOURCES THAT MAY CONTAIN NUCLEAR, BIOLOGICAL, OR CHEMICAL CONTAMINANTS (NBC)

Abstract

A water purification apparatus for removing nuclear, biological and chemical contaminants from water, including toxic industrial chemicals (TICs) and toxic industrial materials (TIMs). One-, two- and three-chamber bladders, bags or hard-shell casings connected to a reverse osmosis filter assembly in either dead-end or cross-flow modes provide chambers to receive raw water, optionally receive and deliver retentate and/or receive purified water. A first contaminated water bag has a sealable inlet, a sealable outlet and a soda-siphon-style valve. A second or third clean water bag or casing has a sealable inlet and a sealable outlet. A hose or manifold is secured between the first and second bag with a reverse osmosis cartridge secured in-line with the hose. The reverse osmosis cartridge includes an optional first pre-filtration stage depth filter, an optional second pre-filtration stage activated carbon filter and a reverse osmosis filter. A compressed air, nitrogen or other inert gas soda siphon style, or pneumatic tool type cartridge secured to the soda-syphon-style or pneumatic-tool-style valve infuses high-pressure gas into the first contaminated water bag to urge contaminated water in the first contaminated water bag or chamber through the reverse osmosis cartridge into the second or third clean water bag or chamber. Adapters to receive other sources of pressurized inert gases and a single-bag system improve adaptability and simplicity of the water purification system.
