The Study of Axial Dynamic Backwashing Dual-Media Filter Experiment

Abstract:

According to the problem of polymeric compound appearing in oil field produced water, following by the changes of water quality characteristics that result in the polymeric compound accumulated in the filter tank which lead to the poor regeneration, being partly hardened and the losing, and the over standard of water quality, the study uses the technology of axial dynamic backwashing to back wash and regenerate the dual-media filter of walnut shell/quartz sand. The removal rate of oil content for filter materials reaches above 90% after backwashing. Simultaneously, cleaning the granular filter materials in filter bed achieves high removal rate of oil and suspended substance content, the average removal rate of oil content being 96.0% while the suspended substance 77.81% which greatly improved the water quality index.
