Overview of Wastewater Reuse Abroad

Abroad, countries such as Israel, Japan, the United States, and South AfricaReclaimed water reuse equipmentThe development is very good. The scope of reclaimed water reuse in the United States is very wide, involving multiple fields such as urban reuse, agricultural reuse, domestic reuse, and industrial reuse. As early as 1925, tourist attractions in the Grand Canyon in the United States used treated wastewater to flush toilets and irrigate lawns. In the future, the implementation of various water-saving measures in the United States, combined with the reuse of reclaimed water, can save more than half of the planned water usage.

Japan is a country with a severe shortage of drinking water, and many major cities in Japan suffer from insufficient water supply. Therefore, Japan has become one of the early countries to conduct research on sewage reuse, mainly focusing on treated wastewatersewage treatmentAs a mixed use water for residential communities and building life. Major cities in Japan have dedicated industrial waterways, forming another urban artery that coexists with the water supply network.
