The Eco-Smart Waterworks System

T

he global water shortage and uneven water supply and

demand problems are getting serious. According to a

UN-Water analytical brief in 2013, one in six people world-

wide does not have access to improved drinking water sources.

Climate change dramatically affects water environments, causing

increases in frequent and heavy rainfall events, high turbidity in

water and algal blooms. In Korea, the concentrations of taste and

odour-causing substances such as geosmin and 2-Methylisoborneol

(2-MIB) in raw water have increased up to 1,000 nanograms per

litre (ng/L) during the summer season. Conventional drinking

water treatment processes could not remove high turbidity or the

taste and odour-causing substances effectively. Climate change is

an increasingly significant challenge in water supply.

The Centre for Eco-Smart Waterworks System at Yonsei

University was established in May 2011 and funded by the

Ministry of Environment of Korea as a part of 10-year Global Top

Project.

The centre has more than 50 academics and industrial

partners and an overall budget of US$72 million for five years.

Its main goals are to:

• develop advanced hybrid membrane water treatment systems

for safe and sustainable water supply

• develop total solution processes based on ET-IT-NT integrated

technology covering the entire process from raw water intake to

water treatment plant to the tap

• promote the growth of global water companies.

The global water market has rapidly expanded over

recent decades and is expected to grow even faster in

the coming years. The Korean Government has desig-

nated water business as a new growth engine and, like

many countries, has been building national strategies

for promoting the water industry.

The centre develops world-class membrane technol-

ogy, a high-tech intelligent optimized water treatment

system, and a water treatment process optimized for

export markets. Its three main technologies for the

drinking water industry are:

• fouling and chemical-resistant membrane modules

with less energy consumption

• hybrid membrane processes for the treatment of

drinking water from various water sources

• the Eco-Smart Waterworks System with a total

solution based on ET-IT-NT technology.

Korean engineering and construction companies have

extensive experience in the design and construction of

waterworks systems in domestic and oversea markets.

However, they have limited experience in the opera-

tion and maintenance of waterworks. The centre has

supported participating companies to obtain opera-

tion and maintenance experience with the cooperation

of local governments such as Seoul and Daegu. This
