In the treatment of oily sewage in oilfields, there is a problem that the water quality of the sewage does not meet the standard. There are many factors that cause this situation, the most important of which is the problem of the filter. Filtration is the last means to remove suspended solids and oil The contained suspended particles, oil and algae are intercepted and adsorbed in order to meet the corresponding standards.
The use of fiber ball filters in it can effectively improve the treatment effect. How Fiber Ball Filters Work Suspended solids will accumulate on the surface of the medium and form a filter cake through bridging, filtration and other processes to improve the accuracy of filtration. At the same time, the pores of the filter material will also be reduced, increasing the resistance of filtration.
When the resistance increases to a certain level, the bridging relationship will be impacted by the subsequent suspended particles and then destroyed, and new larger suspended particles will replace the destroyed bridging relationship, and continue to filter the suspended solids in the oily sewage.Poolking.
