I am curious about your response. Just how does your system "electrify" the oil as to partake in an electrochemical reaction of sorts?

Electro-coagulation as I understand it involves the introduction of additional substance - that has electrical charge - to react and precipitate out the impurities, hence my curiosity with respect to oil which fundamentally has no electric charge.

Dear Akash, I Googled "separation of coolant oil from water" and found the following I thought would be of interest to you. One thing I'm wondering, is your "coolant oil" truly an oil immiscible with water or is it partially soluble in water?? If it is considerably soluble in water, some distillation process might be more appropriate. In any case check thes links out and submit questions to those you might think have answers for you.

If your oil is immiscible in water a good, relatively inexpensive, proven solution is an oil/water separator:

It is a simple concrete tank with three sections. The sections are separated by top baffles. The oil/water mix enters the first section and as the oil naturally rises to the surface the cleaner water flows under the first baffle into the next section which has a plastic packing (similar to cooling tower plastic fill) this gives increased surface area to enhance the oil and water separation. The clean water flows under the next baffle where there is a discharge pipe.

We have several of these in us at our plant and have not had an oily discharge.

What you are looking for is a Liquid/Liquid Coalescer. The type you will need is determined by the level of solids/particulate in the stream, how "clean" you want to get the water and the operating temperatures, line pressure, etc. Googling or using Global Spec will net you hundreds of suppliers of these. If you do not know all the "players" that are in the oil/water stream, spend the money and get the oil/water mix tested before you contact any suppliers. This will help you to set up a performance specification and tell your potential supplier what type of coalescer you will require as well as if any settling and/or pre-filtration is required.

If it is immiscible, you can decant most of the oil after allowing it to float out on the top of the water.

A centrifuge is also a common way to separate any liquids of different density that do not mix, or mix well. Its probaly one of the faster methods used too....

A Heli-Sep is the standard in the marine industry these days.

  • Most of the coolants conatin Ethylene Glycol and Propylene Glycol.
  • Findout the boiling points of the above two
  • Conduct Industrial distilliation at boiling points of Ethylene Glycol and Propylene Glycol.

Hope this helps,

Venu
