Exxflow, a term often associated with environmental and water treatment, refers to a specific type of crossflow microfiltration system developed by WesTech Engineering Inc. This innovative technology plays a crucial role in effectively removing suspended solids, bacteria, and other contaminants from various water sources, resulting in cleaner and safer water for diverse applications.
Understanding Crossflow Microfiltration:
Crossflow microfiltration is a membrane filtration process that utilizes a porous membrane with tiny pores to separate particles from a liquid stream. Unlike traditional dead-end filtration, where the feed stream flows perpendicular to the membrane, crossflow filtration utilizes a tangential flow, meaning the feed stream runs parallel to the membrane surface.
This tangential flow helps prevent clogging of the membrane by minimizing the accumulation of particles on the membrane surface. Instead, the majority of the particles are swept away in the permeate stream, resulting in a cleaner filtrate.
