Introduction of PDVF Hollow Fiber Membrane

'Membrane Bioreactor' (MBR)  is an advanced and high efficient wastewater treatment technology. It integrates membrane such as microfiltration or ultrafiltration membrane with a biological process. The use of membrane as a filter, MBR process rejects the solid materials which are developed by the biological process, and results in a substantially clarified and disinfected effluent of high enough quality to be discharged to sensitive receiving bodies or to be reclaimed for applications such as urban irrigation, utilities or toilet flushing. Furthermore, membrane replaces  the function of secondary clarifier or settlement tank for solid/liquid separation. This provides a number of advantages relating to small footprint, effectively biological removal of ammonia and phosphor, process control and product water quality.
