POSCO E&C develops decentralised water supply system

South Korea based construction company POSCO E&C has developed a decentralised water supply system in co-ordination with K-water and Kolon Global.

The new innovation comprises of a vertical system as its core technology and supplies water through decentralised water systems.

It can be installed at smaller locations as it does not require a big site.

This new system can reduce chlorine usage during water treatment by up to 50%, the company claimed.

POSCO E&C claims that chances of contamination during supply of water can be reduced, compared to long distance supply.

POSCO E&C research and development center director Yong-min Kim said: "We can establish the foundations for safe and reliable water supply systems through developing this system. We will spur the development of core technologies on water."

Excluding POSCO E&C, 14 other companies were part of the development process for the technology, as a part of the water management R&D project of South Korean Ministry of Land, Infrastructure and Transport.

Separately, the company completed the Gwangyang East Revetment Desalination Water Supply project, which will supply desalinated water to the Gwangyang mill and Gwangyang city.

Implemented through an engineering, procurement, and construction (EPC) process, the plant will supply 30,000 tons of water every day.

The facility uses technology for the direct coupling of ultrafiltration (UF) and reverse osmosis (RO) as well as the low-energy RO desalination technology, using rainwater blending to cut construction and operation costs.
