Features
This process consists of high-efficiency mixer£¬sedimentation tank£¬863 filtration technology and highly integrated ultrafiltration device, characters of each process show as follow:
1. High-efficiency mixer
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. Sedimentation tank
(1) Inclined-tube sedimentation tank: with the advantages of high precipitation efficiency, small cell body and small land occupation. The water turbidity is generally 500-0-1000 NTU, the handling ability of single tank should not be too large;
(2) Advection sedimentation tanks: with the advantages of lower cost, easier operation, simpler construction, stronger adaptability of the raw water turbidity, greater potential and more stable handling ability. The general water turbidity is less than 5000NTU, but the land occupation is larger.
3. Automatic flocculant dosing system
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.
4. DA863 filtration technology
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 the same water quantity, it can effectively reduce the area, save construction investment, and improve water quality;
5. Highly integrated ultrafiltration device
The ultrafiltration device is a membrane filtration product of high- precision. It adopts system integration theory which is designed according to the structural characteristics and operation process of hollow fiber membrane.
This product has many advantages listed below: large capacity of single product, high filtration precision, good water quality, small footprint, low cost investment, stable running flow and small pressure fluctuations. Besides, this product can achieve on-line backwash that can maximize filtering performance of the hollow fiber.
