200 Lake Drive Glasgow, DE 19702 | 888-353-0303 | Fax: 302-369-0938 STB-010 SCEPTER TECHNICAL BRIEF Caustic Recovery in Waste Streams LIQUID FILTERS | GRAVER TECHNOLOGIES | 1-888-353-0303 | GRAVERTECH.COM Application: Caustic Recovery Application Detail: Recovery of Caustic from Waste Streams Graver Product: Graver Technologies Scepter Discussion: Caustic recovery of CIP streams in food , pharma and the textile industry is of significant importance as caustic is expensive and its disposal creates a hazardous waste treatment problem. The contaminated dilute caustic from these processes is commonly concentrated and recovered by evaporation. However, evaporators cannot recover highly contaminated caustic. In the past, it had to be neutralized prior to disposal. Graver Technologies patented membrane technology can clarify highly contaminated caustic for reuse. By combining its experience in polymer research, membrane technology and process engineering, Graver Technologies brings you customized solutions to your most pressing waste minimization, raw material recovery or liquid processing problems, including caustic recovery. Graver Technologies Customized System Provides • Cost savings Reduced waste caustic discharge Reduced purchased caustic requirements Reduced energy requirements • Process improvements Cleaned caustic for reuse Improved evaporator efficiency Reduced evaporator blowdown Waste treatment savings • Low capital investment • Low operating and maintenance costs • Custom designed turnkey system • Leasing/rental options • Worldwide marketing and technical support team The Technology Graver Technologies' caustic recovery system is based on SCEPTER patented filtration technology, which combines porous stainless steel tubing and state-of-the-art, formed-in- place titanium dioxide (TiO2) membranes. This creates a smooth, foulant-resistant membrane that permits the processing of dirty or hostile fluids over a broad range of chemical conditions, pressures and temperatures, often where no other membrane device can be used.
