Micro-flocculation filtration

This process consists of high-efficiency mixer and DA863 filtration technology, characters of each process show as follow:

1. High-efficiency mixer has characters of less head loss, simple equipment, without civil structures, no external power equipment and good mixing effect within the design flow range.

2. DA863 filtration technology has characters of high filtration rate, high precision, low backwash water consumption, resistance against shock loading, the use of air-water backwash and surface-water sweep, good washing effect. Under same water quantity, it can effectively reduce the working area, save construction investment, and improve water quality; 

3. Automatic flocculant dosing system adopts streaming potential principle and on-line measurement of net charge strength after being added flocculant, can real-time change the dosage to get the best flocculation and save medicament.

Therefore, this process has characteristics of low investment and high efficiency, generally applicable to advanced treatment for secondary treatment effluent of WWTP.
