The oilfield wastewater remains unflocculated and opaque after treatment
Thread Content
After adding polyaluminum chloride and polyacrylamide to oilfield wastewater, the flocculation effect is poor, and large, tightly clustered flocs cannot be formed. After passing through the inclined plate oil removal tank and two stages of filtration, the water quality was significantly improved. However, after the treated water has rested for a while, it becomes cloudy again; no particles can be seen in the water, but it remains hazy and opaque. Could everyone help analyze what exactly is in the water that causes this situation, and how should it be dealt with? Urgent! Urgent! Urgent! ! !
