Greentech Lead India: GE announced its zero liquid
discharge wastewater recycling technology will be installed at the Posco Cold
Rolling Mill Steel Plant in Maharashtra, India in the second quarter of 2013.
According to General Electric, 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, 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. 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,” said Kyung
Sun Kim, project manager for POSCO.
“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 Engineering, which later changed
its name to POSCO Engineering after a 2011 merger in the POSCO group.
