ABSTRACT

Treatment technologies for water reclamation and reuse probably represent the most essential segment in integrated water resources management. A variety of technologies with dierent nature, processes, and means used exists for the treatment. A treatment technology can be employed singly or in combination with other technologies and processes for the optimum treatment result, which is also the usual practice. Due to the numerous available technologies and processes (Figure 31.1), there is a respectively high number of possible ow diagrams for the treatment train that can be adopted, depending on the specic characteristics of each reuse application. e basic principle of wastewater treatment plants is the optimum removal of the various pollutants present in wastewater. e necessary level of wastewater treatment is dened by the euent limit concentrations, which needs to be fullled before the nal discharge of the euent, and by the option of water reuse of this treated euent.
