RO brine wastewater recovery up to 95% Duraflow, a manufacturer of tubular membrane filters, has announced new DF-ROBR tubular membrane technology for RO brine wastewater recovery. The company’s high-efficiency DF-ROBR technology is designed to deliver up to 95% recovery of Reverse Osmosis (RO) brine wastewater. The pre-treatment chemistry is custom designed for complete softening and removal of RO fouling components. This low-fouling membrane technology solves water shortage problems by maximizing reuse and enables recycling of large volumes of brine wastewater. The wastewater is pumped at a high velocity through the membrane modules connected in series with low inlet pressure of 60 psig. The turbulent flow, parallel to the membrane surface, produces a high-shear scrubbing action which
minimizes deposition of solids on the membrane surface. During operation, clear filtrate permeates through the membrane, while the suspended solids retained in the re-circulation loop are periodically purged for further dewatering. Duraflow tubular membranes are capable of handling high solids concentrations and the chemical resistant property of PVDF allows the use of a wide range of chemicals – acids, bases and oxidizers for cleaning of the removed fouling substances. www.duraflow.biz

UK Eco Park waste-to-biogas project to process 40,000 tonnes annually Global engineering and construction company M+W group has selected GE’s Jenbacher gas engines and Monsal advanced anaerobic digestion system for a new ‘Eco Park’ waste treatment and biogas-toenergy facility in Surrey, UK. The two low-NOx gas engines are being provided by Clarke Energy, GE’s authorized distributor of Jenbacher gas engines. GE made this announcement at the IFAT trade fair which took place from 30 May – 3 June 2016, in Munich, Germany. The Eco Park’s anaerobic digestion facility will process 40,000 tonnes of food waste annually from households in Surrey. With GE’s Monsal anaerobic digestion system, the new facility will convert the food waste into biogas that can generate renewable electricity and heat. The www.filtsep.com
biogas produced will be used to fuel two of GE’s Jenbacher J416 biogas engines, which are configured to generate up to 50% of the common limit for NOx and will provide a total of 2.4 MW of electrical power. After powering itself, the Eco Park will supply energy to the national grid. The Eco Park is being built on behalf of Surrey County Council and will supply baseload renewable power to the local distribution network while providing an alternative to landfill in the form of anaerobic digestion. www.gepower.com

China BlueTech Awards 2016 Los Angeles based industrial wastewater specialist, OriginClear, and Milwaukee-based stormwater company, PaveDrain have won the first ever China BlueTech Awards. OriginClear and PaveDrain competed against a field of 30 water and wastewater technology companies from Europe, Israel, and North America, all focused on demonstrating their technology’s readiness for China market. OriginClear’s advanced water cleanup technology, ElectroWater Separation (EWS), is based on electrochemistry and will tackle China’s most recalcitrant type of pollutants. Scalable, with a low operational cost, it will be incorporated as a modular add-on to existing water treatment sites in China or built as a standalone process flow. PaveDrain’s solution for stormwater also captured the attention of the judges. The PaveDrain system was created under the premise of
allowing stormwater runoff from streets, roads, roofs and parking lots to quickly infiltrate into the ground. This places less stress on the sewer systems, can help reduce localized flooding and helps water infiltrate back into the groundwater table. Following over three years of research and development in North America, PaveDrain is now strategically aligning with China’s Sponge City initiative to bring its infiltration system to China. www.aquatechtrade.com/china/ innovation/china-bluetech-awards

Microdyn-Nadir joins IFAT 50th anniversary This year, IFAT, the water, sewage, waste and raw materials management trade fair, and membrane and module supplier Microdyn-Nadir both celebrated their 50th anniversaries. Microdyn-Nadir, and Huber, a solutions provider for water, wastewater and sludge treatment, officially presented their new VRM module with a total membrane area of 9200 m2 per module. Huber´s rotating system now uses Microdyn-Nadir´s membrane laminate technology which is said to distinguish itself from other technologies by making the MBR modules backwashable and providing them with a selfhealing mechanism. Moreover, the laminate allows for reliable effluent quality.
Microdyn-Nadir presented the new Bio-Cel L, Microdyn-Nadir’s submerged membrane module for membrane bioreactors based on flat sheet membrane laminate. Starting with 10 m2 per module, Microdyn-Nadir launched The BioCel XL with 1920 m2 membrane area per module at IFAT 2014. www.microdyn-nadir.com
