Setting standards for treatment of wastewater before discharge is a major policy instrument for water authorities, balancing environmental gains and operational costs. Discharge permits usually define concentration limits at the discharge point of the plant effluent. This approach, however, may not ...
In recent years, stringent discharge standards prior to the release of effluent into the water bodies have led to the implementation of diverse advanced biological treatment processes in various industries. Biological treatment is a fundamental part of industrial wastewater treatment, contains soluble inorg...

Using national pollution census data,we analyzed the scientific merit and feasibility of increasing discharge standards for municipal wastewater treatment plants.By constructing two functions,investment and operating costs,we calculated the total national costs of municipal wastewater treatment and associated re...
Discharge standards are among the most important regulations to control pollutants discharged from industries and domestic uses. China has made great efforts to build up its discharge standard system and develop methods to derive limits. However, there is still a lack of systematic analysis of measure...
Industrial wastewater treatment refers to a range of physical, physico-chemical, and biological methods used to remove pollutants from wastewater in order to meet specified discharge standards. It may also involve the recovery of valuable substances and the consideration of water recycling and reuse. ...
