Korea urges research and development for global water market

In the next 40 years urban populations will grow by at least one million every week.

According to the International Water Association’s (IWA) Executive Director, Mr Paul Reiter “Water professionals need to change the way they think about sourcing water, and using it over and over again.”

Mr Reiter announced at a press conference in Seoul on Monday that future technologies and approaches to providing sustainable water solutions will be centre-stage at the upcoming International Water Association (IWA) World Water Congress & Exhibition in Korea in September.

He says the most important message of the Congress for the expected 5,000 water professionals who will attend, will be to hasten the uptake of these new water management options.

“We need to break the orthodox approach to delivering water to urban communities,” says Mr Reiter.

Across the globe, water is an issue for many different reasons, including stable supply, sanitation, drainage, wastewater reuse, industrial management, or the environmental impact of new water technologies.

Between 2009 and 2050, urban populations alone are projected to increase by 2.9 billion to 6.3 billion. This equates to a new city every week with a population of around one to 1.5 million—similar to Auckland, Harare, Kuala Lumpur, Beirut, Copenhagen, Brisbane or Prague.

“We are facing this rather daunting problem of getting water to people who aren’t even served today—and on top of that, serving the million people a week who are coming into cities,” says Mr Reiter.
Korea’s ambitious desalination research projects in Busan, a city of almost 4 million and host of the IWA World Water Congress and Exhibition, will significantly raise global standards for water treatment technologies, including seawater engineering and desalination.

In 2013, the city will be operating the world’s largest seawater reverse osmosis plant of its kind based on a measure of its unit train and membrane size. The plant will use membranes with a 16-inch diameter—double that of the current global standard.

“The purpose of the Busan project is to do the research and development, operate the technology on a practical level, then export the core technologies,” says Professor In S. Kim, Executive Director of the Center for Seawater Desalination Plant in Korea.

“The greatest benefit will be the outcomes of the research and development that can be used in regions of the world where there are long-term water shortages, especially with the uncertainties presented by climate change.”

“The project is aimed at exploring overseas markets by developing integral and strategic technologies,” said Professor Kim.

Seawater reverse osmosis desalination requires a lot of steps—intake, pre-treatment, the reverse osmosis process, and post-treatment processing.

“A lot of the tasks in the research are required to be solved or improved and this will present a lot of opportunities in the water sector,” says Professor Kim.

Young-Whan Kim, Director General for Busan City’s Environment and Green Zone Bureau, says the citizens of Busan have a deep distrust of the Nakdong River water intake, which supplies 94 per cent of the city’s drinking water.

“It was necessary for Busan City to find an alternative source of water supply that can replace the Nakdong River, which suffered frequent water pollution accidents in the past,” Mr Kim says.
“We have decided to implement the new desalination plant project to restore public trust in the overall water supply system,” Mr Kim says.

“There has been no back-up source of water supply in case of any river pollution accidents. The new desalination plant, therefore, promises to diversify the sources of water resources and produce high-quality tap water for Busan.”

The new desalination plant will be capable of producing 45 million litres of water daily, which is enough to provide drinking water for 50,000 households. The average water use per person per day in Busan is 301 litres.
