新加坡新生水满足四成用水需求
原标题: How does a city-state with almost no natural freshwater now supply up to 40 percent of its national water demand from treated used water pushed through advanced membranes?
新加坡通过NEWater计划将污水经微滤、反渗透和紫外线消毒处理为再生水，满足高达40%的全国用水需求，大部分供工业使用，干旱期少量注入水库间接供饮用。其能耗远低于海水淡化，产能仍在扩建，以应对2065年需求翻倍。
