Abstract

A transformational approach to water treatment is provided that incorporates membrane-free filtration with dynamic processing of the fluid to significantly reduce treatment times, chemical cost, land use, and operational overhead. This approach provides hybrid capabilities of filtration, together with chemical treatment, as the water is transported through various spiral stages.
