SCEPTER ® Stainless Steel Membrane

SCEPTER membrane systems are used to best advantage in demanding applications where extreme process conditions or difficult feed streams make other separation methods unsuitable. The cross-flow systems have been proven especially effective for high solids or very viscous fluids, or where processing must be done at elevated temperatures and/or pressures, or at pH extremes. SCEPTER systems combine rugged tubular stainless steel membranes with a patented coating technology, in which a sintered titanium dioxide coating is permanently bonded to the porous stainless steel tube. This inert, highly...

SCEPTER technology has been used successfully for over twenty years across a wide spectrum of industrial and commercial applications, including: Agro-Food Wet corn milling, corn syrup clarification, modified starch filtration, fructose polishing, cane sugar clarification, beet sugar clarification, scums filtration, caustic recovery and others Textile Synthetic warp size recovery, dye recovery, caustic recovery and others Pharmaceutical/Biotech Fermentation broth concentration and clarification, protein separation and recovery and others Nuclear Power Enriched uranium recovery, low-level...

W ate r cro mo lec ule Sa s lts Ma tic les So lid Pa r Microfiltration (MF) Nominal pore size 0.1µm Microfiltration is used to separate suspended solids from dissolved substances in a process stream, or to concentrate fine colloidal suspensions. MF membranes separate or reject particles from about 0.05–0.1 micron to about 1 micron, such as silica, kaolin, yeasts, bacteria, dextrose “mud,” granular starch and pigments. Sintered TiO2 membrane Typically, SCEPTER tubes are welded together into all-stainless steel membrane modules, resembling shell-and-tube heat exchangers. These modules – plus...

as close to “real” as practical. If you have an existing membrane test system, it may be possible to retrofit it with a SCEPTER membrane module. Alternately, Graver and our system providers have test systems of different sizes, designs, and degrees of automation, as the application may call for. The nominal equipment rental fees will often include start-up assistance, test plan development, and test data evaluation. All or part of the rental fees may be refundable on a full-scale purchase. While SCEPTER stainless steel membrane modules can be supplied alone, they are generally incorporated...

Pharmaceutical industry: Separation and harvesting of microbial cells For many applications, SCEPTER filtration is the only option; no other membrane is up to the job. In fact, SCEPTER modules are often specified as replacements where other membrane technologies have tried and failed. In other cases, the advantages of flexibility, reliability and long service life make SCEPTER the clear, cost-effective choice. Here a just a few of the cases where SCEPTER technology is making a measurable difference in product quality, cost savings and environmental impact. Grain industry: Corn syrup...

Sugar industry: Cane sugar clarification Metal finishing industry: Alkaline cleaner recycle Raw cane juice must be clarified to remove objectionable amounts of lignins, gums, dextran, waxes, and other colloidal impurities that contribute taste and color to the crystalline form of the product. This raw juice undergoes several steps, such as clarification using lime or flocculating agents, to remove much of these contaminants prior to evaporation and crystallization steps. SCEPTER systems are being used to improve the clarity of the thin juice immediately after the clarification step. SCEPTER...
