Dear forum members, I have been working on an oil & water separation project. The oil contamination is less than 200 ppm in process stream which is a 10~15% aqueous ammonia. My objective is to reduce oil to less than 1 ppm. Conventional oil/water separation methods(gravity settling, centrifuge) are good in achieving separation up to 10 ppm, but for going less than that is not possible with them.
Can any body guide me to some unique techniques which have small footprint and are able to achieve what I require??
Thanks in advance

Re: Oil Water separation techniques
I have similar experience with one my clients, and it all comes down to the composition of oil that is being separated, and there are different technologies available for it. Also you cannot effectively separate oil if you don't have the right separation technology built in to the separator process. Most of the plants which I have observed have interceptors installed and they confuse it with separators. These are just empty tanks with baffled walls and no effective separation technology. 1 PPM is probably an unrealistic goal because most of the available technologies of the day give you 10 PPM for oil, hydrocarbons, diesel, gasoline, fuels etc. The best I have seen is 5-7 PPM
