Watch the full RTL reportage on COOL Separations and our sustainable water treatment technologies for treating the most difficult streams from the industry!

COOL Separations is at IFAT 2018 in Munich! We are part of the experience.science.future sector in hall B4, booth 150/250. See you there between the 14th and the 18th of May!

COOL Separations (formerly known as EFC Separations) and PROXA announce their cooperation to jointly deliver commercial scale eutectic freeze crystallization (EFC) units to treat highly contaminated waste streams.

Initially developed by COOL Separations, the innovative EFC process was commercialized through joint development work in PROXA’s Process Development Laboratories. It is targeted at challenging environmental applications, including acid mine drainage and highly concentrated brine streams. EFC technology enables treatment of highly contaminated effluent to produce reusable water and different by-products, which can be tailored according to various needs. Key benefits of the technology include simple & stable operation, no added chemical consumption, and an overall smaller footprint.

Our Eutectic Freeze Crystallization pilot unit travelled to Paarl, South Africa for running tests on a stream originating from the mining industry. The pilot tests give insight on the most suitable process and equipment design for the coming full scale plant to be commissioned in late 2018 on a major coal mining site. The goal is to achieve ZLD while producing clean water to be reused on site as cooling water and detergent grade salt.’

‘Successful demo tests were ran at the location of our client with the purpose of concentrating vegetable juice. A concentration factor of 10x corresponding to more than 90% volume reduction was reached. Our pilot unit was purchased by the client and we are currently working on building a full-scale industrial Freeze Concentration plant.’

‘Successful demonstration of the feasibility of EFC treatment of an effluent from a commercial demin water instalation.’

‘The large surplus of animal manure brings the need for the economical processing and reuse of this by-product of the meat industry. FC technology proved successful with achieving over 80% volume reduction of a liquid manure stream.’

‘Using one of our mobile pilot plants, under EFC conditions, high quality nickel sulphate and well filterable ice were produced from a bleed solution supplied by Umicore. In the two week testrun, process and equipment proved to be robust and reliable during continuous run.’

‘Eutectic Freeze Crystallisation was successfully applied in a scaled up version of a scraped cooled wall crystalliser on an industrial aqueous sodium carbonate – sodium bicarbonate waste stream containing traces of molybdenum.’
