Influx of Projects Underscores Acceleration of Chinese Market and Expands Successful Commercialization of Oasys’ Forward Osmosis-based Zero Liquid Discharge Technology in Region
Boston – July 28, 2016 – Oasys Water, a world leader committed to developing innovative solutions for transforming industrial wastewater into valuable freshwater resources, today announced that the company is actively deploying three new industrial wastewater treatment projects in China and is expanding its Asian operational infrastructure to support growth in the region. These new projects include a massive commercial project at Zhongtian Hechuang Energy Company Limited, the world’s largest coal-to-olefin (CTO) project to date. Oasys and its Chinese partner, Beijing Woteer Water Technology Co., Ltd. (Woteer), were selected to provide a Zero Liquid Discharge (ZLD) water treatment plant for process effluent streams at the $3.1 billion coal-based methanol petrochemical plant under construction near Ordos, located in China’s Inner Mongolia Autonomous Region.
Woteer will provide a ZLD water treatment system, featuring Oasys’ forward osmosis (FO) technology, to transform 3,200 m3/day of process wastewater at the CTO complex, the largest of Oasys’ three new projects. At five times the capacity of Oasys’ initial commercial project in China at the Changxing Power Plant, this new deployment will utilize two of Oasys’ Membrane Brine Concentrator (MBC) systems in parallel, to transform high salinity process wastewater into fresh water to be recycled in the plant’s production process. The massive ZLD water treatment system will include the MBC systems and Polishing RO from Oasys along with pretreatment and crystallizer systems provided by Woteer, making it a model to showcase Oasys MBC scalability and the two companies’ unparalleled process solutions for China’s growing ZLD and water reuse markets.
“The combination of our successful commissioning of the Changxing Power Plant last year and the continued acceleration of the Chinese ZLD market has driven Oasys to grow its presence in the region and expand the breadth of our activities with our Chinese partner, Woteer,” commented Jim Matheson, president and CEO of Oasys Water. “China has clearly established itself as the world’s leader in adopting innovative technology to tackle challenging industrial wastewaters, and this growth has allowed Oasys to rapidly scale the development and deployment of our technology. This growth has also positioned us well operationally to serve other regions such as India, Korea and the Gulf Cooperation Council from our China-based facilities as this next wave of target markets accelerate adoption of ZLD solutions for industrial wastewater transformation.”
Oasys and Woteer are also in the final stages of commissioning a ZLD project for treatment of combined power plant wastewater streams of 1,200 m3/day at the Yangmei Taihua CTO complex in Shanxi province, where Woteer will be the owner and operator of the plant – another important first for the Oasys and Woteer partnership. Both the Yangmei Taihua and Zhongtian projects feature process flows similar to Changxing Power Plant, with pretreated wastewater concentrated to 220,000 mg/L TDS or higher in the MBC prior to brine crystallization.
Finally, Woteer was recently awarded a third project featuring Oasys FO-based MBC technology, for treatment of flue gas desulfurization (FGD) wastewater to ZLD at Shanxi Lujin Electric Power’s Wangqu Thermal Power Station, a coal-fired power plant in China’s Shanxi province. This plant will utilize an MBC system for brine concentration of a 370 m3/day stream to 240,000 mg/L for combination of the effluent brine with a flyash byproduct. The system design for Wangqu follows the award-winning process design from Changxing, further setting the standard for China and global power market ZLD solutions.
In 2015, Oasys Water and Woteersuccessfully commissioned and deployed the world’s first commercial application of FO-based ZLD through a project at the Changxing Power Plant to desalinate the coal-fired power plant’s FGD wastewater. The wastewater treatment system was recognized with an award of distinction at this year’s Global Water Awards, sponsored by the publication Global Water Intelligence, in the category “Industrial Water Project of the Year.” The Changxing plant is now treating up to 650 m3/day of FGD wastewater, transforming it into freshwater to be reused in plant operations. The plant’s MBC system operates at higher than 90% recovery and the full system provides complete water recovery at lower capital cost and operating cost than evaporator-based offerings.
