High Solids Ultrafiltration with HTI's SepraMem™ Systems

HTI has pioneered unique versions of High Solids Ultrafiltration aimed at separating oily wastewaters. Targeted at industrial and food manufacturing applications, HTI's SepraMem UF family of membrane products available in spiral wound cartridges, are your ultimate solution to oily wastewater applications.

Many industries and processes produce difficult to treat waste streams, cutting fluids and wash down product that contain high concentrations of emulsified oils and fats. Regulations typically require aggressive filtration or treatment before discharge and traditional waste treatment solutions are ineffective or prohibitively expensive.

When used to separate emulsified oils and fats from wastewater streams HTI's SepraMem UF technology:

• Resist high solids fouling
• Substantially improves water quality
• Provides an energy efficient solution
• Eliminates the use of dangerous chemicals and compounds, thereby reducing environmental impact

In High Solids Ultrafiltration, hydrostatic pressure forces high concentration solution against a specialized semipermeable membrane filter to dramatically remove suspended solids. HTI's SepraMem UF technology is widely applicable for filtration or concentration of difficult commercial and industrial waste streams. One of the membranes in HTI's SepraMem UF family is sure to allow you to configure a filtration or concentration system that will satisfy your needs.

HTI's innovative SepraMem™ family of Ultrafiltration products provides the complete solution for your oil/water separation wastewater problems. With SepraMem™ membranes, HTI engineers have created a unique flat sheet membrane that is extremely oleophobic while at the same time highly hydrophilic. In short the SepraMem™ membrane hates oil, but loves water.

In state-of-the-art manufacturing facilities, we form unique spiral would cartridges packing our membrane in a design that allows minimal feed stream pressure drop with very high fluid velocities, enabling separation with minimal membrane fouling.

HTI's oleophobic SepraMem™ membrane acts as an ultra-filter allowing water and other small molecules to pass while rejecting and concentrating the oily wastes. The technology is ideally suited for emulsified oils generated from metalworking, hydraulics and aqueous parts washing. In most cases the alternative is expensive evaporation or hauling and disposal. A few examples of the many applications for HTI's SepraMem™ are:

• Oil and gas E&P produced water
• Emulsified oily wastewaters
• Colloidal silica concentration
• Wastewaters from food processing
• Wash waters from metal chip processing
• Metal working fluids
• Industrial laundry
• Pretreatment to reverse osmosis
• Alkali wash recycle

HTI manufactures a complete line of SepraMem™ equipment that that can handle all of your separation needs from 250 to 40,000 gallons per day. In addition, our applications engineers are standing by to meet any of your custom needs for larger systems.
