Abstract:

The application of the automatic drugfeeding equipment with variable frequency and speed to microflocculation-filtration technics,the usage of PFC,the characteric of the automatic drugfeeding equipment and the situation of its usage are all introduced. It is found in practice that PFC has preferable effect and can remove a certain amount of PO₄^3-. The control of feeding amount is accurate,the power consumption is low,the operational cost is less, and the work done is reliable. It ensures the quality of outgoing water.

Key words: variable frequency and speed, drug-f eeding equipment, microf locculation- f iltration, treated water reuse
