Oasys and its Chinese partner Beijing Woteer Water Technology Co Ltd are providing a Zero Liquid Discharge (ZLD) water treatment plant for process effluent streams at Zhongtian Hechuang Energy Co Ltd’s US$3.1 billion coal-based methanol petrochemical plant under construction near Ordos, in China’s Inner Mongolia Autonomous Region.
Woteer will provide a ZLD water treatment system, featuring Oasys’s forward osmosis (FO) technology, to transform 3200 m3/day of process wastewater at the coal-to-olefin CTO complex. This new deployment will use two of Oasys’s 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 huge ZLD water treatment system will include the MBC systems and Polishing RO from Oasys along with pretreatment and crystallizer systems provided by Woteer.
Oasys and Woteer are also in the final stages of commissioning a ZLD project for the treatment of combined power plant wastewater streams of 1200 m3/day at the Yangmei Taihua CTO complex in Shanxi province, where Woteer will be the owner and operator of the plant.
Woteer has recently secured a third project featuring Oasys FO-based MBC technology, for the treatment of flue gas desulfurization (FGD) wastewater to ZLD at Shanxi Lujin Electric Power’s Wangqu Thermal Power Station in China’s Shanxi province.
“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,” explained 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.”
