Welcome to 4th Phase Technologies

At 4th Phase Technologies, Inc. (4PT) we’re pioneering the future of filtration with a breakthrough that’s as simple as it is transformative: our chemically densified carbon nanotube (DCN) membrane.

 

This isn’t just another filtration solution—it’s a game-changer for how the world approaches filtration.

 

By solving the persistent challenges of traditional polymeric membranes—high pressure requirements, fouling, and frequent replacements—we’re shifting the economics of filtration and unlocking a new era of efficiency and sustainability.
