overview :
The Solution For Industrial Cleaning Wastewater Reuse System mainly adopts membrane bioreactor (MBR) technology, . This is a new process that combines biological treatment technology and membrane separation technology. Youdaoplaceholder3 aims to efficiently carry out solid-liquid separation, , thereby obtaining stable reclaimed water that can be directly used. The MBR technology significantly enhances the system's solid-liquid separation capacity by using membrane modules to replace the secondary sedimentation tank in traditional processes, . At the same time, it can maintain a high concentration of microorganisms in the biological tank, , and reduces the process's excess sludge.
Solutions and advantages of reclaimed water reuse equipment:
In the pretreatment stage, the focus is on removing residual chlorine from water. A reduction system design is adopted to address the fatal impact of excessive residual chlorine on reverse osmosis membranes
2. In terms of reverse osmosis arrangement, a higher recovery rate is designed without affecting the service life of the equipment
3. For the selection of reverse osmosis membranes, Dow reverse osmosis membranes from the United States are chosen. The effluent quality is stable and the PH value cleaning range is relatively high
4. In terms of operation control, an automatic operation design is adopted to reduce the impact of human error on the equipment belt
5. In terms of management mode, the concept of process management and continuous improvement is adopted to achieve customer satisfaction and meet the requirements of ISO9001.
