The PurBev philosophy not only covers plant design, but also mandatory standards for managing the entire value chain – including purchasing appropriate materials and components; production, logistics, assembly and startup tailored to suit the specific requirements on hygiene; and special training for operators and service personnel. This holistic approach ensures maximum safety and quality in water treatment whilst reducing the risk of contamination through improper handling of systems.

MD replicates conventional thermal process whilst using less energy
G
eneral Electric Co (GE) and Memsys Clearwater Pte Ltd report that a vapour compressor-driven membrane distillation (VC-MD) system they are developing has successfully completed a field test at a commercial disposal well based in Texas, USA. During the test it operated continuously for 200 hours. The system, which is used to concentrate produced water from the hydraulic fracturing process, has been designed to reduce produced water disposal costs and enable water reuse. The joint project demonstrated that MD combined with vapour compression can handle the high salinity of produced water associated with unconventional gas exploration and production. The companies say the field test has yielded positive results which include:

Membrane Technology
‘As the cost of brine concentration comes down it will enable more sustainable treatment options compared with trucking and deep well disposal,’ explained Bill Heins, General Manager, Thermal Products, GE Water and Process Technologies. ‘Since the cleaned water from the process can be reused it will also reduce the amount of fresh water needed per well, thereby further reducing costs and ecological impact.’ With the project complete, the companies plan to continue to demonstrate this technology in other geographies and applications, as well as scaling up the process. Götz Lange, CEO, Memsys, added: ‘The ability to treat even the most challenging wastewater with our process in combination with a vapour compressor, instead of the normally used waste heat, increases the number of possible applications even further.’ ‘GE has been an excellent partner on this technological breakthrough, and we look forward to continuing commercialising this technology for produced water treatment for the oil and gas industry. In this context, Memsys is increasing the production volume for its modules eight-fold – sufficient for the installation of up to 50 000 m3 of daily water treatment capacity annually, which will be used across all possible applications for the Memsys process.’ GE and Memsys entered into an agreement in 2012 to jointly develop MD technology (also see Membrane Technology August 2012, page 1) for the fast-growing unconventional resources market place, including shale gas, coal seam gas and other unconventional fuels recovered by hydraulic fracturing. Under the terms of the agreement GE will invest in testing the technology and in return receive an exclusive licence for the use of the technology in these applications.

Denmark-based DSS Silkeborg A/s, which develops membrane filtration technology for the dairy industry. Established in 2000, DSS is a privately held company with 46 employees that develops, designs, sells, builds and commissions membrane filtration systems for dairy applications, using reverse osmosis, nanofiltration, ultrafiltration and microfiltration technologies. The core competence of DSS lies in maximising the full use of milk and whey, based on its understanding of fractionation processes, water treatment and dairy production. ‘Becoming an integral part of Tetra Pak, a large multinational company focused on the dairy sector, offers DSS an opportunity for a new phase of growth in the global dairy industry,’ commented Niels Osterland, Managing Director, DSS, and the firm’s co-founder. Tim High, Executive Vice President, Processing Systems, Tetra Pak, added: ‘The acquisition of DSS adds to Tetra Pak’s expertise in membrane filtration technology, enabling it to provide its customers with an even wider range of processing systems for dairy, cheese and whey as well as other beverages and prepared foods.’ ‘The integration of DSS’ expertise with Tetra Pak’s energy, waste and water reduction technologies will provide our customers with processing technology designed to reduce their carbon and water footprint as well as their operational costs.’ DSS will remain in Silkeborg, Denmark, with its current management team, as part of Tetra Pak’s cheese and powder business unit. Existing sales channels will be supplemented through Tetra Pak’s global market operations.
