I am a bit late to comment.This problem was communicated to Swami Valmiki Sreenivasa Ayyangarya and another scientist based in India. The oil spill in wells, thereby contaminating the water can be treated by Swami Valmiki Srenivasa Ayyangarya and rendered safe on a sustainable basis. Unless we receive an invitation from the government sources, we cannot step in.

These kind of discussions are really welcome . Many thanks to AquaSPE.

Mr. Subramaniam, Greetign s from the USA. There adre menay methods of dealing wth this problem, but we have ti start with the basics. What is the source of this pollution? This will determione the amount and viscosity of the oil. from thewre ar ethere are many erchnologies available to rectify this problem. If you would kindly let me know the answers i will give you severtal solutions.

The removal of Oil from groundwater to make it safe to drink, the following process they can be used:
1. firstly you need to have skimmer, size it can depend on the borehole discharge l/s
2. Ultra filtration to trap some of suspended solids or use package plant after the water passes the skimmer.
3. Package plant it depend on the number of reservoir, in order to store raw water and final effluent.
4. Reservoir must have scour valve especially, the one that is going to receive water from the skimmer before get it package plant/ ultra filtration.

Hoping that you are answered any clarity make follow up on that I will explain clearly to you. Don't hesitate to contact me, you can arrange then I will do it practical to you.

Tank you,
Phetla

This problem is no different than the one that the oil companies who are drilling into the shale plays of the country are experiencing. Back in 2004 Cal-Neva Water Quality Research Institute out of Newcastle California worked with Devon energy on the problem of recycling of what was called Slick Frac Water which was a product of the natural gas drilling to get it from the shale. We developed a water cleaning system that is called Electo-coagulation. The system uses electrodes and cathodes of a special design in a specially designed system to allow the water to go through tubes containing these electrodes and electricity is used to destroy not only the oil in the water but it kills every living thing in the water such as virus, bacteria, algea ETC. The oil comes out looking like specs of black pepper and the water is then drinkable. More info can be read on this at www.eco-web.com then click on Editorials and then on Authors and look for the white papers by Dr. Abe Beagles on the subject. Or you can call him at 916-877-1553.

Bonjour
Is it possible to remove the contaminated oil from ground water used for agriculture and drinking ?
Tout ceci est de l'ordre du -Biologique- et c'est jouer avec le feu de vouloir recycler des eaux polluées pour l'agriculture ou la consommation d'eau potable.
Il faut savoir que le terme pollution n'est pas exclusivment réservée à ce qui se voit: les micros particules chimiques et la pollution chimique diffuse ne se voient pas mais elles existent.
Peut être qu'en premier il serait bon de remonter jusqu'à la source pour trouver les causes de cette pollution et commencer par les éliminer. Traiter de l'eau souterraine polluée sans se préoccuper de la source de la pollution n'est pas une vision objectif.
Que dire de cette eau souterraine polluée avec laquelle des millions de gens s'approvisionnent dans leur habitat pour leur consommation journalière?
La problématique des membranes même les plus sophistiquées laisseront toujours passer la pollution diffuse invisible mais toxique.
Dans le concept d'Assainissement Biologique nous mettons en place diverses fonctions pour éliminer la matière organique, biologique, tout en demandant l'adhésion à la biologie attitude en supprimant tout utilisation de produits d'entretien ménagers contenant des micros polluant chimiques.

All this is about - Biological and it is to play with fire to want to recycle the water polluted for the agriculture or the consumption of drinking water.
It should be known that the pollution term exclusivment is not exclusivment booked with what is seen: the micro chemical particles and chemical pollution diffuses are not seen but they exist.
Can be that in first it would be good to go up until the source to find the causes of this pollution and to start by eliminating them. To treat groundwater polluted without being concerned with source of pollution is not a vision objective.
What to say this polluted groundwater with which million people is supplied in their habitat for their daily consumption?
The problems of even the most sophisticated membranes will always let pass invisible but toxic diffuse pollution.
In the concept of Cleansing Biological we set up various functions to eliminate the organic matter, biological, while requesting adhesion from biology attitude by removing any use of domestic maintenance products containing of micro the pollutant chemical.

Hι Sivakumar,

My experience on this topic has to do with the use of constructed wetlands (CWs). I was involved in a related project in Germany, in one of the largest industrial areas of the country (chemical industry, petrochemical, oil refineries). The groundwater there was heavily polluted for many decades with hydrocarbons, phenols etc. We tested first in pilot scale several designs of CWs and we resulted with the optimum design. Since last June the full-scale system is operating and is treating onsite the contaminated groundwater. We calculated that within a period of 5 years money saved are almost 1.7 million euros compared to conventional mechanical technologies (air stripping etc.). Another project took place in Oman: the problem there was that during oil extraction, water containing oil was also coming out. Using hydrocyclones we managed to separate the oil from the water (95% removal) and the pumped water was followingly treated in constructed wetlands for the removal of hydrocarbon content. The treated water was then used for irrigation (we were in the middle of the desert...). Generally, this technology seems very promising and effective, while it is sustainable since the energy consumption is minimum (usually only for pumping) and maintenance costs are respectively reduced. I would be glad to discuss with you further should you have any questions.
Best regards,
Alex

Did you ever think of looking to nature? For example, the milkweed plant's seed fibres naturally absorb oil. Hay also does a good job with absorbing oil. Here's a YouTube video that show a small sampling of this: https://www.youtube.com/watch?v=k5SxX2EntEo

It is indeed possible to clean the water and there are numerous technologies that can be used. One important aspect to understand is whether there is an oil/water emulation as this emulsion will have to be broken in order to remove the emulsified oil from the water. It is possible to break the emulsion and get very clean water. Do you perhaps have any water quality?

Sivakumar,

When you state "contaminated oil", that typically means oil that has been discarded after use. This could mean that the oil has elevated heavy metals which can contaminant oil from part wear. I would be very careful about considering this for drinking water even if the organic fraction could be removed to acceptable levels.

i would not recommend to use this water contaminated with oil to produce potable water. It will be contaminated with a sort of soluble oils that can be dangerous to the health.

Although I am not an expert on Water purification, common sense tells me that oil does not mix with water. Taking this cue, one can adopt two methods for oil removal - through selective filtration which removes oil and then followed by routine treatment for reuse; secondly, there are specific bacteria which thrive on oil and they suck the oil out for the remaining water to be routinely treated.

oil removing from ground water is the part of pre treatment process.there is two popular process are oil removal. first is chemical treat ment and another is ACF treatment system.

By using oil/water separation through the use of ultra filtration (UF) membranes.
