| Abstract: | Study on filtration technology in advanced wastewater treatment for municipal wastewater reuse has been conducted. The results showed that most of the SS could be removed from the secondary effluent of sewage treatment plant by direct filtration process, with dual medium of ceramic granules and sand, at 5.2m/h flow rate. The filtration period was about 61.2- 72.1h. Compared with direct filtration, combiued processes of microflocculation-filtration and coagulation-sedimentation-filtration were more effective and with better effluent quality, but filtration period of the processes decreased to only several hours at flow rate of 8.8m/h. |
