description

 

This talk describes a novel technology platform relevant to many water purification applications, including water reclaim. The innovation will impact current infrastructure by improving performance and reducing energy, resource, time, and footprint. Compactness, scalability, modularity, speed, and low system maintenance allow for potential implementation in potable water and water recycling for small communities to large urban cities.

The innovation is a hydrodynamic separation mechanism derived by controlling fluid dynamics in curved channels. Features include: a high throughput, purely fluidic, continuous flow, membrane-less, size-selective method for separation, especially of neutrally buoyant suspensions; and precipitation and/or accelerated aggregation kinetics from enhanced mixing and custom fluidic shear for floc conditioning. Together, the combined effects allow for controlled growth and rapid separation of suspensions; fully eliminating sedimentation.
