ULTRA-SMALL FOOTPRINT MEMBRANE FILTRATION ANALYSIS SYSTEM
Static Test Cell (STC) Membrane Filtration System
Real-time Analysis
The SpinTek Static Test Cell (STC) is a high-shear, high-capacity membrane filtration system that provides valuable time and cost advantages in testing feed solutions and membrane filtration viability. The STC system provides more efficient assessment of membrane suitability for filtering a wide range of liquid products using small volumes of feed solution. The results from the STC can be used to design larger field demonstration systems or assist in the design of full-scale filtration products. In addition, the data developed from the STC system provides a low cost, simple method of screening feed solutions as candidates for membrane filtration.
Ultra-small Footprint
SpinTek`s advanced test platform consists of a membrane filtration system, instrumentation and a feed pump. These bench-scale sized systems collect membrane performance data on a wide variety of feed samples. Perfect for evaluating the suitability of micro, ultra, and nanofiltration membranes, the STC module accepts any flat sheet filtration membrane ``coupon`` that is available in 3″ x 4″ (75mm x 100mm) size. Each STC membrane test system includes one flat-sheet membrane test sample. The STC accepts polymeric or ceramic membranes. In addition any flat membrane sheet that can be cut into ``coupons`` can be used in the STC.
Key Benefits

The SpinTek Advantage
SpinTek is an industry leader in the research, development and manufacture of ceramic membranes and high shear filtration systems. SpinTek`s advanced filtration systems resist fouling from oily, sludgy, caustic and highly concentrated feed streams. The STC test platform was developed exclusively for laboratories—whether university, private industry or government labs—involved in analyzing membrane filtration viability and feed stream analysis. The STC system`s low cost, efficiency and versatility in testing a variety of membranes and streams brings a new level of performance and time savings to the test process. Contact SpinTek to learn more about STC and their membrane filtration system design.
Membrane Innovation
To improve filtration efficiency in the STC system, SpinTek developed a new ceramic membrane with a pore size range from 0.07 to 0.5 microns for the filtration of high-temperature and/or chemically aggressive solutions. The membrane has a thin titanium dioxide/alumina/silica dioxide layer on top of a stainless steel substrate. The top membrane coating is 15 microns thick while the lower substrate is 250 microns. The very small size of the nanopowder ceramic produces a smooth-to-the-touch surface that resist the trapping of contaminants within the pores of the membrane.
STC process and instrumentation
Below is a process and instrument diagram (P&ID) of the STC bench-top testing equipment. The process solutions are pumped from the feed tank to the STC membrane system. A variable speed pump is used to control the flow to the system. A backpressure control valve is used to maintain a constant pressure on the membrane system.
Advanced Tubular Ultrafilters
Wide Center Channel Decreases Fouling With High Solids Streams
Tubular Ultrafiltration Membranes from SpinTek™ provide excellent capabilities for filtering and concentrating difficult process and waste streams. The tubular filters feature a wide center channel design, and can handle high concentrations of suspended solids with ease, allowing the passage of even large solids without plugging your system. The ability to handle feed streams with widely varying compositions and characteristics makes these reliable, long-lasting tube membranes excellent replacements in nearly any existing in-plant system. SpinTek tube membranes concentrate latex and kaolin, oily wastewater, nuclear waste, and many other hard-to-handle streams.
Low Maintenance
In addition to their ability to concentrate difficult waste and process streams, SpinTek`s Tubular Ultrafiltration Membranes feature excellent low-maintenance properties. They are designed to the most rigorous standards of performance, offering superior membrane composition with exacting tolerances. SpinTek`s optional Spongeball Cleaning System for automatic or manual operation can be added to facilitate fast, easy cleaning and inhibit the build-up of deposits that degrade system performance. So in addition to savings in concentrate disposal, you`ll achieve dramatically reduced downtime, and lower maintenance costs.
Key Benefits
- Tubular filters have a wide center channel - which better handles feed streams with large solids and high levels of suspended soils without clogging
- Excellent, cost-effective replacement tubes fit nearly any existing in-plant systems
- Direct replacement of Koch™ Products
Lower you`re Replacement Costs
SpinTek Tubular Ultrafiltration Membranes are available in industry-standard diameters and lengths, providing a direct replacement for nearly an existing system, regardless of manufacturer.
