Molecular thin film prevents water loss in Singapore

摘要

Singapore's 3000 hectare reservoir system loses more than 45 million cubic metres of water annually through evaporation. This evaporation loss reduces supplies not only from rainwater, but also from all other sources stored in the reservoirs, including water brought in from neighbouring Malaysia. Additionally, this 'leak' will likely increase with predicted higher maximum temperatures associated with anticipated global warming. To maximize the available -water resources, PUB, the national water agency of Singapore, is looking for cost-effective methods to reduce evaporative losses for its 17 reservoirs.
