Biological treatment

Hello Sivakumar,

Some comments refer to simple oil water separation but this will not take care of the fraction of the oil which formed an emulsion and is sort of dissolved in the water. Another thing to consider is that oil contamination caused by humans is usually a mixture of different hydrocarbon chain lenghts and aromatics. Even after oil water separation you will encounter these substances in the water phase. Therefore its not suitable as drinking water or even irrigation water.

I would recommend a physcio-chemical pretreatment followed by biological treatment of the water. This will take care of the majority of the hydrocarbons in both free phase as "dissolved" phase. To upgrade this water to irrigation water I suppose an Ultra Filtration step will be sufficient. Drinking water quality would require reversed osmosis.

For treating the groundwater prior to well extraction you could consider in situ remediation technologies. We offer a system which is able to promote biodegradation of oil in groundwater. It could be installed  around these wells at a certain distance to create a treatment zone in the aquifer. This would save you expensive above ground equipment.
