WebOct 22, 2024 · Introduction. (Updated August 2024) Solids Retention Time (SRT) is a critical activated sludge design and operating parameter. The selection of an SRT has many consequences related to process performance, sludge production, and oxygen requirements. the traditional method for controlling SRT is to manually adjust the sludge … WebApr 15, 2024 · Microwave-induced oxidation and UV/TiO2 photocatalytic technologies are widely used for organic wastewater treatment. Furthermore, the combination of these technologies (MW/UV/TiO2) result in a new advanced oxidation process. As a green and efficient photocatalytic degradation technology, MW/UV/TiO2 is favored for its …
