Oil Water Remediation

Published on by in Technology

We have a ​serious case of ​groundwater ​contamination ​at Nisisioken ​Ogale, in Eleme ​LGA.

The pollution ​is due to the ​Nigerian ​National ​Petroleum ​Company product ​pipeline in ​proximity of ​which an 8 cm ​layer of ​refined oil was ​observed ​floating on the ​groundwater ​which serves ​the community ​wells.  ​

Total ​petroleum ​hydrocarbons (​TPH) are ​30,000 for the ​adjacent ​soil. ​

How can we ​most efficiently ​and economically ​remove the oil ​from the ​already ​contaminated ​groundwater? ​

  1. Wonderful concept.  The "pays for itself" statement is a bit hard to swallow. Technology not new.  the (ORI) oil recovery initiative was developed at The University of Texas at Austin. Research done in the 70's, testing and field trials in the 80's, went public in the early 90's. I do like the idea of recovery as it fits the ZERO Waste concept.  Boils down to Recover or clean it. we call it remediation. Nature calls it bioremediation. using of oil eating microbes with zero waste and no residue.  short view.....  more options, more profit.

  8. I might be a bit late to this question. But I would suggest an organic Microbe that is completely safe for humans, fauna and flora. All you need is a dosing system and some aeration for the water and some on site soil remediation (can be done by manual labour and the right products).

    I would suggest talking to someone from Tala Engineering Projects if this is a problem you still have, or for anyone reading through with the same problem. They are based in South Africa and have a lot of expertise in solving problems like this.

    2. Hello Mary

      The only solution is to supply you with drinking water elsewhere. As Helen says it is an important continual deep pollution. At first you have to go to the source of pollution and remove it!!!!!

      Then allow time to clean up this pollution (a few years)

      Contaminated water is for ongtemps and of course micro organisms will never manage to purify this pollution

    3. Bonjour Mary 

      la seule solution c'est de vous approvisionner en eau potable par ailleurs. comme le dit Helen il s'agit d'une pollution continuelle profonde importante. Dans un premier temps il faut aller à la source de la pollution et la supprimer!!!!!

      Ensuite laisser au temps le temps de nettoyer cette pollution ( quelques années)

      l'eau contaminée l'est pour l'ongtemps et bien entendu les micros organismes n'arriveront jamais à épurer cette pollution

  9. Thank you.  What corporation do you think makes the best nanobubbling machines?

    1. A lot of marketing seems to be posted here. One thing for sure man and machines will never be able to do the job that nature has evolved to do over a few billion years. I believe asking many questions of artificial cleanups is in order. Get cost estimates on each offer. See if any can compete with nature.  Good luck.

  10. A hand or small boat skimmer should remove the oil from the water. Please email for details rosjonesenvedu@hotmail.com 

  11. Hello Mary,

    There are many excellent responses below. On tother additional consideration I would suggest (which you may already have in place), is that you determine the extent to which oil may travel within the aquifer. In my dealings with ground contamination where groundwater sources have been or have the potential to be contaminated, resolution of the problem is not a simple nor short-term solution . I have found by setting up your internal and external boundaries with appropriate monitoring and controls is always a benefit.

    Kind Regards Helen

    1. Helen,  We are using several approaches,  Our site is under 3 feet of water. First we are fencing the area with a membrane fence that will let the water through but not he oil. In this double fences paremeter we will also be using OspreySorb a 30:1 nontoxic cellulose sorbent. then on site we are skimming, the using an incredible product that has incredible results in 30 days, even heavy metals. We will be treating to 60M aquifer. Within the water tables we are using nanobubbling system with our solution! 

      Next week we will be testing to the aquifer level and will have so much more information.

  12. Mary, you will need some free product recovery and then remediation of the contaminated groundwater and soil. It might be worthwhile contacting Verde Environmental. They are already operating in Nigeria. 

     

  14. Hello, we have successfully cleaned-up in-situ, dozens of sites contaminated with hydrocarbons using electro-bioremediation. But it is essential that you always start with removing the free product. This can be done using skimmers or a device we specifically developed for this purpose. If you want more information just let me know

  15. Dear Mary

    If this is floating oil then we have suitable machine which can remove 99% oil from the water.

    after this with suitable DAF method we can remove the dissolved water and make the water suitable for use. 

    pls. send us the detail info at our e mail  info@waterengrs.com .

  16. I understand that OilSolutions International has oilclean up products as microencapsulated spongy or rubbery and resinous materials that scavenge oil from water,so that it can be easily scummed off.

    Microencapsulated adsorben sponges have high oil remediation efficiencies,and ease of removal combined with application and absorption effectiveness

    2. Dear Suresh sir: very keen to learn it more. I am in Gujarat state of India and working with ultra poor farmers. few days back in peak summer in one district of Gujarat there was contamination of aquifer due to oil pipe line puncture. It was difficult situation. if the remedial process is cost effective then we can try to popularize within farmers. regards Biplab Paul T; @BHUNGROO Ph +919825506900

  19. Mary ... Our company has been very successful in removing petrocarbons, oil, diesel and gasoline from water in Europe quite recently. We have used our product to clean small oil spills in QATAR in the past.

    As some in this forum have said, microbiological remediation is the new, inexpensive way to solve your problem.

    We would be more than happy to go over in detail with you the protocols used recently in Europe.

  20. Using the Bioremediation modern technology all you really need to do is apply the ARCHAEA microbial species at a selected point of entry and let them do their natural biological function.  If you remember there are many international cleanups by the ARCHAEA with no residue and extremely low cost to do so.  All of the 1950,s technologies do work. Just a choice of low cost and efficiency.  (go to you tube Megaborg oil spill 1990. ).

    1. Nigeria will not allow any microbial solutions to be used.  The TPH's have been running over 100K

      1. Mary; Someone is pulling a scam. Chemical intervention will not be effective. Only microbial intervention will work. If there is a portion of their infrastructure that will actually inspect each powdered product then I would recommend a very small microbe that is 1/10,000 the size of the smallest bacteria. The RNA group name for this species is Archaea.  The only way you can tell they are there is with a scanning electron microscope. That will only show millions together but never able to see a single one. South Africa uses this microbe more than any other country. The USDA/NOP has approved it as 100% organic and the W.T.O. has authorized its use because of its natural ability to eliminate all pathogens and toxins. When it is shipped into any country with corrupt officials it is identified by its ISO number and as a "Healing Clay"  Which also happens to be true.  I am in Texas. If you want an expert closer to you Jean Marius from France I believe is the most knowledgeable. 

    2. Hello

      The micro organisms are being-living-like you and me like the plant and the fauna and flora that one finds on earth.

      In order to live, these micro-organisms must have satisfactory, appropriate and perennial living conditions.

      The micro organisms are not objects that can be activated on simple desire.

      Living conditions must include biological characteristics that are not found in chemically polluted wastewater.

      1. Bonjour Jean. Como se va. Excellent comment. Few in this industry comprehend the value of microbes in our earths circle of life.  What we call "cleaning" microbes call food. Not all people like the same foods and it is the same in nature. Microbiologist discover a new microbe, determine its' parameters then add it to their data base for to be learned later what they are used for by nature.

        Your analysis is spot on.  When some new technology comes along some are eager to learn and others stick with what they know best regardless of the efficiency and cost of it.  I do not pretend to know your background and training. But I have read many of your comments and the #1 characteristic is your passion to do good things for all using your God given talents.  If you have not already done so allow me to introduce the Archaea microbe. details another comment thread. Classification is an RNA microbe. Has NO DNA structure. parameters are: temp range 28 F to 427 F, ph. range is 5.5 to 10.0, moisture requirements suspense is 2% to 10%, activation is at 10% moisture, best activity level is 50%, can still function at 99% moisture. It is aerobic  and because many species are from volcanos they con fully function at 1ppm of O2. (microaerophilic). DNA bacteria and fungi do not have the genetic code for reducing compounds into their elemental state. Just less complex compounds. Archaea does reduce all compounds into their elemental/nutritional state. This does include the chelation of all metals.(heavy metals/nutrients).   Pleasure to share cutting edge technology.

  21. Dear Mary,

    your water seems to be similar to the produced water (extracted from oil Wells along with the oil). For this water the treatment process is rather standard and based on steps in sequence:

    - CPI (Corrugated Plates Interceptor) to reduce the oil content down to less than 50 ppm

    - NSF (NutShell Filters) to reduce the residual oil content down to less than 5 ppm

    If you need zero oil content, the final AC (Activated Carbons) will ensure the requested performance.

    In some cases an IAF (Induced Air Flotation) is installed between CPI and NSF.

    Should you need more details, please contact me privately (I am a process consultant, not a seller of plants)

  22. Dear Mary,

    Good question, the oil is the dangerous pollutant for aquatic life, it shield the oxygen transfer into depth of water.

    Step by step process for oil water separation when oil quantity s more then gravity system to be used and hen centrifuge oil disc separation etc. following are the process, Centrifugal separation is another process of separating two fluids with contrast in densities. Imparting centrifugal motion creates two streams namely the less dense oil which orients itself along the rotational axis and the denser fluid (water) which orients around the stream of less dense fluid. 

    1. Gravity separation
    2. Oil disc separation
    3. Centrifuge separation by density
    4. Skimmer system
    5.  Microbubble technology. 
    6. partition gravimetric method 
    7.  Dean-Stark Method to separate oil and water. 
    8. Membrane-based filtration systems. 

     

    To separate oil from water, add a solution of soluble ionic salt to the solution. Distillation, which involves boiling and condensing the water, is another option, as well as partially freezing the oil and water combination and discarding one-fourth to one-third of the unfrozen water.

    Regards,

  23. First; it would seem your community needs to have EPA intervention against the oil company for violations of Title 40 for oil/gas pollution regulations. Based on your offered information; the remediation and cleanup will be extensive and expensive. Without much more specific analyses and data; the primary environmental negative impact gives all indications that your situation will require mass soil removal and replacement; a full and comprehensive aquifer pump out; water treatment (tertiary); and return for the whole aquifer. There must be a comprehensive risk assessment conducted for the entire area which the aquifer supplies water to.  In most extreme cases; the aquifer is abandoned and the next deeper aquifer is tapped into for supply to the effected area. This is only a superficial response to your critical matter; again; your federal; state; and local agencies should facilitate legal action for any remediation and restoration actions against the pollution generating industry. The industry should foot the bill for this debacle; not; the people. Please feel free to contact me at : irsd7@verizon.net

  24. Many good answers below, but you first need to start cleanup with bulk removal using highly efficient oil/water separator, then treat the residual water for the balance of trace hydrocarbons, usually with activated carbon (which can be regenerated) and post filtration for secondary removal stages.  Soils can be remediation using standard soil vapor extraction systems and then flushing the soil with hydrocarbon degrading bacteria using the vadose zone as an incubator for growing the bacteria. This is a simple explanation but there are other steps required as well, UV disinfection of treated water, et. al.

  25. I test a special filter material for the removing of oil from contaminated water at time. The adsorptions capacity of this filter material is much higher than charcoal (between 10 and 15 times more). For more information please feel free to contact me directly.

  30. Bonjour 

    ceci est un grave problème qui ne peut se résoudre aussi facilement qu'on puisse le croire avec une solution miracle.L'eau potable met des années à  devenir ce qu'elle est: potable. Quand elle est souillée par une pollution elle perd automatiquement cette caractéristique. Il y a la pollution visible flottante et la pollution invisible dissoute.Déjà dans un premier temps il faut trouver l'origine de cette pollution et la stopper le plus rapidement. Personne n'est en mesure de statuer qu'elle ne va contaminer d'autres réserves souterraines.Ensuite depuis des années je m'insurge contre le fait que le monde prend les milieux hydrauliques naturels pour une poubelle.La problématique de l'eau potable est intimement liée à la problématique des eaux usées sa principale source de pollution.Depuis quand date cette contamination? quel sera son impact sur la santé des gens approvisionnés avec cette eau?

    Ce sera le mal du siècle et des siècles à venir.

     

    Hello this is a serious problem that cannot be solved as easily we could believe it with a silver bullet.

    Drinking water takes years to become what it is: drinking. When soiled by pollution it automatically loses this feature. There is the visible floating and dissolved invisible pollution.Already a first time to find the source of this pollution and stop it as quickly. No one is able to determine that it will contaminate other underground reserves.

    Then for years I protest against the fact that the world takes natural hydraulic environments for a trash can. The problem of drinking water is intimately linked to the problem of wastewater his main source of pollution. Since when this contamination date? What will be its impact on the health of the people supplied with this water? This will be the evil of the century and for centuries to come. 

  31. Hi Mary,

    The problem seems rather complicated. First, as I understand there is both (underground) water and soil contamination with hydrocarbons. This means that water treatment is not enough if soil remediation is not also included.
    For contaminated groundwater, the treatment process depends on the concentration levels of hydrocarbons. A typical scheme we usually apply, includes upstream oil recovery and treatment of the remaining water with residual hydrocarbons via a constructed wetland (a green and cost-effective technology with minimum energy consumption). But we need more info to suggest the optimal treatment train.

    1. Hi Mary

      I agree with Russell Donnelly and Jean Marius, first fix the problem by getting the local environmental authorities involved, because no matter what you do now to clean up the aquifer, that rotten pipe from the Nigerian National Petroleum Company will continue spilling oil into the ground.

      After you fix the source of the problem only then you can start to do the cleanup, there are many technologies that you can be used to separate oil from water, you have to be very careful on which technology you will use, it depends on a number of things such as: is the oil emulsified?, depth of the well, ppm of oil in the water and the most important one, capex and opex, one thing for sure, as Russell and Jean Marius said, it will not be easy or cheap.
