New Membrane Technology – V-SEP
(Vibratory Shear Enhanced Processing) has made it possible to filter streams containing suspended solids without fouling problems exhibited by conventional membrane systems.
Sustainable Services & Products
High Filtration Rates
-
High V-SEP filtration rates average ten times higher than competing separation technologies.
Fouling Resistance
- V-SEP’s patented vibratory shear process keeps the filter surface clean.
Engineered Dependability
- Only two moving parts and a self-repairing membrane system eliminates costly downtime.
Compact Design
- Only 1,5sqm of floor space replaces systems 10 to 100 times larger
High Solids
- Achieving high solids in a single pass simplifies processing.
High Efficiency
- V-SEP’s energy-to-shear conversion rate is 99%.
Pilot Testing
- From small sample testing to pilot simulation, we offer convenience for the African market.
Low Cost
- Reduced energy, maintenance and processing time adds up to low costs.
Vibration
V-SEP’s vibration comes from its one moving part: the eccentric weight-bearing. As the bearing spins, the weight induces a vibratory action that is translated to the seismic mass. The vibration is sent through the torsion spring and on to the filter pack drive.
The filter pack then moves back and forth 54 times per second at an amplitude of 5/8” of an inch (~16 mm). The extreme shear created by the rapid change of direction makes it exceedingly difficult for foulants to attach to the membranes.
Membrane Technology
Membranes have been used to remove dissolved solids from water since the 1950’s, but today’s membranes provide more throughput and better chemical resistance. Membranes allow some things to pass through while rejecting the rest. Thus, any feed stream sent to a membrane system such as V-SEP will be split into two. The part of the stream that can pass through the membrane is called the permeate.
The part of the stream that is rejected by the membrane is called the concentrate. In a product recovery or concentration context, the con is the desirable material. In a wastewater or product clarification application, the concentrate represents a concentrated slurry of undesirable contaminants. There are general classifications of membranes, any of which can be used in a V-SEP.
