Singapore, Mar 9, 2009 - (ACN Newswire) - Professor Gatze Lettinga from The Netherlands has been awarded this year's Lee Kuan Yew Water Prize for his environmentally-sustainable solution for the treatment of used water using anaerobic technology.
His revolutionary treatment concept, which stood out among 39 international nominations, enables industrial used water to be purified cost-effectively and produces renewable energy, fertilizers and soil conditioners. Professor Lettinga has chosen not to patent this invention so that his water treatment technology can be universally available. As a result, his technology has been widely adopted in industrial as well as municipal use. Today, the technology is in use in almost 3,000 reactors, representing about 80 percent of all anaerobic used water treatment systems in the world.
The Lee Kuan Yew Water Prize is an international award recognising an individual or organisation for outstanding contributions in the field of water. Such works have to solve the world's water problems through the application of revolutionary technologies or the implementation of innovative policies and programmes that benefit mankind.
Energy-efficient, Cost-effective Process
Professor Lettinga pioneered the widespread use of anaerobic technology, which uses micro-organisms in an oxygen-free environment to purify used water. Although anaerobic technology has been around for over a hundred years, his invention proved that it could be operated as an energy-efficient, cost-effective and self-sustaining process. His anaerobic reactor is able to pre-treat polluted used water from industries such as breweries, beverage, paper and pulp manufacturing, sugar, starch and alcohol distilleries. The used waters produced by these industries contain a large amount of organic contaminants. Some of these contaminants cannot be efficiently removed by conventional aerobic processes, while others are toxic.
With energy-efficiency concerns becoming more pressing, this technology is being increasingly applied, not just to industrial used water, but also to municipal used water in countries like Brazil and India. The anaerobic system is a simpler system compared to aerobic systems as it does away with the use of oxygen, generating energy savings of 30 to 40 percent.
Before Professor Lettinga's breakthrough, highly-contaminated industrial used water was treated mainly by aerobic biological processes, which were expensive and energyintensive due to the use of oxygen. In countries which could not afford the aerobic process, the untreated, highly-contaminated water would have polluted the environment, affected aquatic life, and even endangered public health.
Self-sustaining System
At the same time, the process also produces methane which is the principal component in natural gas and can be used as a fuel to generate electricity. Treatment plants using Prof Lettinga's technology are able to offset part of their plants' operating costs by generating this renewable power. Other by-products are fertilizers and soil conditioners.
Says Professor Lettinga, "I believe that innovative technologies for treating used water, waste, and gas, especially those that focus on closing the loop and recovering resources, will contribute to more sustainable living which the world urgently needs."
"Professor Lettinga's invention has played an important role in addressing the worlds growing concern over finding environmentally-sustainable solutions. In choosing not to patent his Upflow Anaerobic Sludge Blanket reactor, many developing countries now have access to a low-cost, sustainable used water treatment system. Besides contributing to water management with his technological breakthrough, he has also imparted his knowledge to young water engineers and professionals all over the world so that they can apply the knowledge in their countries. His altruism is indeed highly commendable," says Mr Tan Gee Paw, Chairman of the Lee Kuan Yew Water Prize Nominating Committee.
Nominations for the Lee Kuan Yew Water Prize went through a rigorous selection process. The Nominating Committee, comprising chief executives of multi-national water companies, leading academics and government officers, conducted a thorough examination of all the submitted nominations. It recommended the winner to the Water Prize Council, which is chaired by Dr Tony Tan, Chairman of the Singapore National Research Foundation for its endorsement.
Professor Lettinga says, "I feel deeply honoured and grateful to receive this award because it originates from the small yet astoundingly successful city state, Singapore. More importantly, the Water Prize bears the name Lee Kuan Yew, the impressive and inspiring first Prime Minister of Singapore."
Named after Singapore's first Prime Minister and present Minister Mentor Lee Kuan Yew, the award comes with a cash prize of SGD300,000, an award certificate and a gold medallion. The award is solely sponsored by the Singapore Millennium Foundation, a philanthropic body supported by Temasek Holdings that has pledged SGD1.5 million over five years since 2008.
The award ceremony and banquet will be held at the Istana the official residence and office of Singapore's President on 24 June 2009 during the second Singapore International Water Week. Professor Lettinga will deliver the Singapore Water Lecture at the Water Week on 23 June.
The inaugural Lee Kuan Yew Water Prize was presented to Dr Andrew Benedek in 2008. Dr Benedek is a Canadian researcher and successful technopreneur who pioneered the development of low-pressure membranes that enabled drinking water to be produced from even highly polluted water.
About the Lee Kuan Yew Water Prize
The Lee Kuan Yew Water Prize recognises outstanding contributions towards solving global water problems by either applying groundbreaking technologies or implementing innovative policies and programmes which benefit humanity. This international award is named after Singapore's first Prime Minister and present Minister Mentor Lee Kuan Yew, who through his foresight and leadership, has enabled Singapore to attain sustainable
water supply.
A total of 39 nominations from 19 countries were received when nominations for Lee Kuan Yew Water Prize 2009 closed on 31 October 2008. The nominations showcased not only a wide spectrum of water solutions but also new disciplines in water research and applications.
The range includes application of innovative technologies, implementation of revolutionary water policies and programmes, management of water resources, hydrology and ecology, water research, as well as the administration of humanitarian aid. Compared with last year, 2009's spectrum has also been extended to more niche areas, such as water microbiology, disinfection and used water treatment. All showed a strong understanding of todays needs and showcased innovative yet sustainable solutions.
Almost half of the total number of nominations come from the Asia-Pacific region that include China, India, Japan, Korea, Sri Lanka, Bangladesh, Cambodia, Malaysia and Singapore.
Nominations of the Water Prize go through a rigorous selection process by the Nominating Committee headed by Mr Tan Gee Paw, Chairman of PUB Singapore. The winner of the Water Prize will then be decided by the Prize Council. Chaired by Dr Tony Tan, Chairman of the National Research Foundation, Singapore, the Prize Council comprises of individuals of high international standing from academia, international organizations and multi-national companies.
Named after Singapore's first Prime Minister and present Minister Mentor Lee KuanYew, the award comes with a cash prize of SGD300,000, an award certificate and a goldmedallion. The award is solely sponsored by the Singapore Millennium Foundation, a philanthropic body supported by Temasek Holdings that has pledged SGD1.5 million over five years since 2008.

Professor Lettinga will deliver the Singapore Water Lecture at the Water Week on 23 June.
Dr Andrew Benedek was awarded the inaugural Lee Kuan Yew Water Prize in 2008 for his outstanding work in pioneering the development of low-pressure membranes in water treatment. This dedicated researcher and successful technopreneur has redefined the way water can be treated. He has shown how drinking water can be produced from different water sources, even those that are highly polluted. It is a big leap that benefits mankind, both for those in developed and developing countries.
