GE announced its zero liquid discharge (ZLD) wastewater recycling technology will be installed at the POSCO Cold Rolling Mill Steel Plant in Maharashtra, India in the second quarter of 2013. This marks the first steel mill application of a complete GE ZLD system containing electrodialysis reversal (EDR).
Under the contracts signed between GE and Korean-based POSCO Engineering, a wholly-owned subsidiary of POSCO, GE will supply a ZLD wastewater treatment system, which includes two EDR trains for water reclamation, for POSCO’s new plant. GE also will provide technical services, including operator training, during installation and commissioning of the new facility.
“Because of the ongoing water challenges in this region, it is critical to reduce the high levels of water use for industrial applications,” said Kyung Sun Kim, project manager for POSCO. “GE’s innovative, customized wastewater system will help POSCO address that challenge while at the same time meeting local government regulations for wastewater discharge and supporting initiatives to prevent water pollution.”
“POSCO is using the EDR technology to gain a higher recovery of treated wastewater and the ZLD system for reliable wastewater treatment, both of which help to address the challenges of high water consumption in the region, as well as water scarcity on a global level,” said Jeff Connelly, vice president, engineered systems—water and process technologies for GE Power & Water.
The POSCO Cold Rolling Mill Steel Plant is expected to enter commercial service during the second quarter of 2013. The project builds upon an already close relationship between GE and POSCO Engineering. In 2009, GE supplied EDR technology for a thermal power plant to Daewoo Eng., which later changed its name to POSCO Eng. after a 2011 merger in the POSCO group.
