Benefits

VSEP filtration rates average ten times higher than competing separation technologies.

Membrane-based separations have always had limitations as well as advantages. Limitations such as high operating costs and low filtration rates made them inefficient to work with. Yet the advantages such as precise separation, crystal clear filtrate, controlled size exclusion (from microns to molecular dimensions) and excellent materials compatibility were compelling.

With these advantages in mind, New Logic set out to make the innovations necessary for membrane separations to enter the mainstream. Now, VSEP is the only filtration system offering high sustainable filtration rates (despite high suspended solids) in a single pass.

Achieving high solids in a single pass simplifies processing.

The feed slurry in a VSEP system can be extremely viscous (up to 70% solids) and still be successfully processed. The way it works is simple. As the membrane leaf elements vibrate vigorously, the shear waves produced cause solids and foulants to be repelled and liquid to flow through the membrane pores unhindered. The shear rate at the membrane surface is approximately 150,000 inverse seconds, literally ten times greater than the rates obtainable in crossflow filtration systems.

VSEP’s energy-to-shear conversion rate is 99%!

At the core of VSEP’s highly efficient operation is a patented resonating drive system. This system achieves high energy efficiency by applying shear into a thin zone near the filter surface. This precise application of shear results in efficient energy conversion and very low power consumption. A typical VSEP system consumes less than 20 hp.

VSEP allows nearly 99% of the total energy utilized to be converted to shear at the membrane surface. Compare this to a typical crossflow filtration system where as little as 10% of the energy is converted to shear on the membranes.

Only two moving parts and a self-repairing membrane system eliminate costly downtime.

VSEP is a simple, compact, closed system. Under normal operating conditions, VSEP will require the same level of attention as a pump. It will perform the instant power is applied, and the resulting separation is a pure physical occurrence.

VSEP only has two moving parts: the torsion spring — which is tested to assure infinite life; and the bearings — which are lubricated automatically. Additionally, the patented redundant membrane system, which automatically self-repairs in case of membrane element failure, guarantees uninterrupted performance.

Only 16 square feet of floor space replaces systems 10 to 100 times larger.

A VSEP system occupying only 20 square feet of floor space can support up to 1500 square feet of membrane area and do the work of a system 10 to 100 times larger. The system is also modular for easy expansion. Installation of a Series i system is no more complicated than the installation of a pump.

From small sample testing to pilot plant simulation, we offer convenience.

Test before you invest, and save. New Logic can test your material at our facility to determine general performance parameters and budgetary capital costs. Testing can be as simple as an initial sample test and report provided by New Logic (delivered to you along with collected samples of filtrate and concentrate) or as involved as you wish it to be. You can rent a small-scale system (Series L/P) to collect data on your process in-house, or you can visit New Logic’s modern wet test facility and run your material on a pilot plant system that simulates full-scale operation.

VSEP is customized for your specific application. All data collected during testing is used to customize a Series i system to your specifications. Controls, motor sizing, membranes and materials of construction will be specifically selected to assure an optimized system that will give you many years of trouble-free service.

Reduced energy, maintenance and processing time add up to low cost.

An extremely attractive cost-to-performance ratio combined with VSEP’s exclusive features add up to one of the lowest-cost systems of its kind.
• High flux rates mean more throughput capacity per dollar of capital invested.
• Fouling resistance means less membrane replacement and less cleaning and maintenance due to fouling.
• High solids, achieved in a single pass, simplifies processing.
• High efficiency lowers operating expenses.
• Engineered dependability eliminates costly down time.
• Compact design means savings on installation, space requirements and plant design.
• Convenient testing lowers cost by limiting technical risk.
All these benefits add up to make New Logic’s VSEP the low cost separations alternative.
