China could become a leader in wastewater management
13/Sep/2006: With most of its rivers and lake polluted with sewage from urban areas, China is trying to tackle this problem by spending more on its wastewater treatment infrastructure.
The Chinese government will spend $41.5 billion by 2010 to develop wastewater treatment plants in all cities. If they choose to invest this money in next generation treatment plants, which reprocess water more effectively, they could become a leader in wastewater management. Treatment plants that use the latest technology can reduce water scarcity in the country and also cuts down the costs for cleaning polluted waterways, boosting the economy of the country.
However, rivers and lakes in China may take years to recover from the damage already done to them, as much of their ecosystems are shattered by pollution. China is most populous country in the world with more 1.25 billion people and suffers from acute scarcity of water. The country is investing heavily on projects to transfer water from the river in south to arid north, but only effective management of water resources can solve the water scarcity in this country.
One of the new systems that are being tested for wastewater management, uses microbial fuel cells to produce power from the waste separated from water by the treatment plants. The electricity generated will be used to power the same treatment plants. The investments in wastewater management will also help the bottom-line of many Chinese companies, as they get to manufacture and market new water treatment systems in future.
