The real time and online monitoring system for zeta potential of wastewater in papermaking process is studied. With help of the device using streaming potential method to measure zeta potential, and by adopting PLC and WinCC, the real time online monitoring system based on zeta potential is built; various indexes and zeta potential values in wastewater handling process are collected and displayed in real time. Within the range of allowable error, the system can be used in flocculation section for guiding the put-in amount of the flocculant, thus the target of optimizing flocculant is reached. In addition, the system features excellent man machine interface. The system possesses good applicable prospect in flocculation section of industrial fields.
