Innovative Platform Technology for Selective Removal of Dissolved Contaminants from Raw Water

An emerging water treatment technology that operates purely by fluid dynamics without the need for physical filtration. This novel technology uses centrifugal force to create transverse fluid flow patterns to separate a suspension of particles into two streams: one concentrated in particles, and the other devoid of particles. Unlike existing hydrocyclones and centrifuges, which require particles in the suspension to have a different density from the liquid medium, this technology can also address neutrally buoyant suspensions. Added benefits include no moving parts, low energy, high scalability, minimal footprint, continuous-flow operation, high modularity in construction, and low cost in materials and TCO.

Removal of dissolved contaminants is achieved by adapting conventional adsorption, coagulation and flocculation, or lime softening and/or soda ash (or pearl ash) protocol as a pre-treatment mixingconditioning step prior to hydrodynamic separation. This technology has been tested on many raw water matrices. Results for efficient removal of dissolve hydrocarbon, scaling agents, and dissolved silica are discussed.
