Pulsating Valve for Mechanical Membrane Biofouling Prevention

详细技术说明

This innovation generates a pulsating flow through the membrane, which provides enough pressure to detach the colonies of bacteria before they can form large patches and ultimately an extensive biofilm.

*Abstract

Designed for reverse osmosis water desalination plants, this technology is a mechanical method that reduces the need to clean biofouled membranes within an enclosed continuous fluid flow system. Organic matter present in water or other fluids tends to attach and grow on surfaces within the boundary layer of the flow. Filters and membranes are subject to clogging as these biofilms form, which reduces flow and requires frequent cleaning. By pulsing the flow of liquid, this technology reduces the amount of organic material that collects on membranes, minimizing downtime for cleaning cycles, prolonging membrane life, and lowering replacement costs.
