UV kills all known […]
Read More →Particles to be filtered usually fall into one of two categories: Non-deformable particles that under normal conditions (temperatures) do not deform. In some instances, non-deformable particles can become deformable with a temperature or chemistry change—an example of this would is a particle of resin, which at ambient temperatures may be solid, but at elevated temperatures […]

(Brian Gartside/Courtesy of pAge Drinking Paper) Imagine a book that has pages you can tear out and use to turn raw sewage into drinking water.

Filtration processes using membranes could potentially reduce energy consumption compared to other separation methods. The membrane is very thin, […]
