EnglishMembrane-based separation technologies are widely deployed across industrial applications, yet each category bears distinct strengths and drawbacks. Conventional membrane technologies suffer from inherent limitations including severe membrane fouling and low permeate flux, driving excessive operational expenses and rendering such systems operationally inefficient. The VSEP Vibratory Membrane System engineered by NEW LOGIC (United States) specifically addresses the core deficiencies plaguing standard membrane treatment technologies and expands process options for end users.
1. Exceptionally High Permeate Flux
VSEP delivers filtration rates 10 times higher than competing separation technologies. Its standout advantages encompass precision filtration, superior permeate quality, controllable retentate volume (covering micron-scale to molecular-scale separation) and broad feedstock compatibility.
Building upon these competitive edges, New Logic has pioneered breakthrough membrane filtration technology to mainstream industrial adoption. To date, VSEP remains the sole filtration system capable of sustaining consistently high flux throughout single-pass filtration, regardless of suspended solids concentration in feed streams.

2. Superior Anti-Fouling Performance
VSEP’s patented vibratory shear technology maintains continuous cleaning of membrane surfaces. Multiple core functional advantages exclusive to VSEP stem from this vibratory shear mechanism. The shear effect enables high-throughput separation spanning low-molecular-weight solutes up to 30-micron particulates, marking VSEP as the first and only equipment of its kind to deliver a genuine paradigm shift in filtration technology, retaining a multi-year technological lead over rival systems.
The ultra-high-frequency vibratory shear filtration mechanism delivers remarkable performance: intense shear waves propagating across membrane surfaces resolve long-standing membrane fouling challenges by scouring accumulated solids and contaminants off membrane surfaces. High-flux filtration is sustained even for feeds with ultra-high solid loading.
- No loss of target product (a critical drawback of centrifuges and filter presses);
- No requirement for coagulant additives (unlike rotary drum filters and clarifiers);
- Significantly reduced energy consumption (compared with evaporators and biochemical treatment units).
3. Treatment of High-Solids Wastewater
Single-pass filtration simplifies the entire separation workflow for high-solids wastewater streams. VSEP efficiently processes highly viscous feed suspensions with solid concentrations up to 70 wt%. Its operating principle is straightforward: shear waves generated by high-frequency membrane vibration repel suspended solids and contaminants, allowing unobstructed liquid permeation through membrane pores.
4. Exceptional Energy Efficiency
VSEP achieves an energy-to-shear force conversion efficiency of up to 99%.
At the heart of VSEP’s high-efficiency design lies a patented resonant drive system. It delivers concentrated shear force to discrete zones on membrane surfaces to maximize energy utilization, realizing efficient power conversion and minimal energy draw. A standard VSEP unit consumes less than 20 horsepower. Nearly 99% of input electrical energy is converted into surface shear force on VSEP membranes. By contrast, conventional cross-flow filtration systems only achieve a mere 10% energy conversion efficiency.
5. Robust, Reliable Design
With merely two moving components paired with a self-repairing membrane assembly, VSEP drastically cuts costly unplanned downtime. VSEP adopts a compact, fully enclosed simple design; its routine maintenance requirements are comparable to those of standard water pumps under typical industrial operating conditions. The unit starts up immediately upon power connection and consistently produces high-purity permeate.
VSEP’s two sole moving parts include:
- Torsion springs: proven to deliver indefinite service life;
- Self-lubricating bearings.
Complemented by a patented redundant membrane system that automatically compensates for failed membrane elements, the design guarantees uninterrupted continuous operation.
6. Ultra-Compact Footprint
A standard VSEP unit occupies only 16 square feet of floor space, outperforming competing systems that demand 10 to 100 times larger footprints.
A single VSEP module occupying just 20 square feet delivers a total membrane area of 1,500 square feet. Alternative membrane systems require 10–100 times more floor area to achieve equivalent membrane surface area. The modular architecture supports seamless capacity expansion, and installation of the Series i VSEP units is as straightforward as installing a standard water pump.
7. Convenient Testing Services
We provide full-spectrum testing support, ranging from lab-scale small-sample trials to pilot-scale demonstration runs.
Front-end laboratory testing prior to capital investment delivers substantial cost savings. New Logic can process customer feedstock on our in-house test equipment to define baseline operational parameters and budget estimates. Testing workflows are streamlined equivalent to initial small-sample screening. Upon test completion, New Logic issues comprehensive test reports and delivers physical samples of permeate and retentate to clients (sample delivery is optional per customer requirements). Additional testing options include:
- Client rental of bench-scale L/P model units for independent data collection;
- Customer site visits to New Logic’s humidity-controlled pilot testing facility, where feedstock can be processed to simulate full-scale industrial operating conditions.
8. Low Total Cost of Ownership
Cost reductions stem from minimized energy expenditure, reduced maintenance labor and shortened processing cycles. Coupled with VSEP’s exclusive proprietary functional advantages, its outstanding operating cost ratio delivers the lowest total cost of ownership among comparable separation systems:
- High flux maximizes production output per unit capital expenditure;
- Anti-fouling performance reduces membrane replacement frequency and cuts cleaning/maintenance overheads;
- Single-pass high-solids separation streamlines end-to-end process workflows;
- Energy-efficient operation slashes continuous operational expenses;
- Reliable mechanical design eliminates costly production downtime;
- Compact footprint simplifies installation and saves valuable plant floor space;
- Flexible pre-investment testing mitigates technical risks.
All integrated advantages position New Logic VSEP as the most cost-competitive membrane separation solution available.
9. Application Sectors
VSEP excels in treating complex industrial fluid streams including high-salinity wastewater, flue gas desulfurization wastewater, landfill leachate and industrial waste liquor, while also featuring extensive applicability in food & beverage deep processing. Compared with traditional spiral-wound membrane systems, VSEP delivers distinct operational cost advantages, validated by numerous successful domestic and international industrial reference projects.
Within the new energy industry, VSEP delivers substantial economic benefits across core process workflows, including phosphoric acid purification and lithium extraction from salt lake brines.
To facilitate client feasibility testing, we maintain a dedicated pilot test platform. By installing basic piping and storage vessels at project sites, clients can conduct 7×24-hour continuous industrial pilot trials. Trials generate primary experimental datasets directly applicable to full-scale engineering design, substantially mitigating project technical risks and operational uncertainties.
