Niagara and New Logic Research cooperate on a new breed in water filtering technology, the Vibratory Shear-Enhanced Process (VSEP) brine minimization system
A new Niagara Bottling facility is being built as part of an agreement reached between Niagara and New Logic Research. The two companies' agreement will see the creation of a new breed in water filtering technology, the Vibratory Shear-Enhanced Process (VSEP) brine minimization system.
Designed to pick up where reverse osmosis (RO) systems leave off, VSEP systems introduce an alternative method for dealing with fouling, which clogs the filtering process.
Cross-flow filtration systems often suffer from fouling as solids build up in the filter's boundary layer. This layer is located just above filtering membranes where the solids are caught.
Liquids are allowed to pass through small pores in the membrane, but as solids build up the pores become blocked.
Cross-flow systems address this issue by creating a shear wave on contact with the membrane, pumping liquids through the system at high velocities. This technique is limited to low-viscosity fluids like water and has only proven to lead to premature fouling.
New Logic's VSEP system introduces an alternative for producing more intense shear waves to prevent blockage in filters without sacrificing performance.
In the VSEP system liquids flow at a meandering pace and the membrane itself vibrates. The vibrations of the membrane are so intense that the shear waves produced bounce the solids back. VSEP's open channel flow-path prevents any buildup.
