Water and wastewater

Water is indispensable to human life and production activities. The quality of drinking water is closely related to human health. Drinking water comes from surface water and groundwater. If the source water quality is polluted, it will affect human health and drinking water safety. According to the World Health Organization survey, 80% of human diseases are related to water pollution. In developing countries, 12.4 million people die each year from lack of clean drinking water. Drinking water safety has attracted great attention.
