Removing or Treating Edible Oil from Waste Stream
Removing or Treating Edible Oil from Waste Stream
(OP)
We extract an edible oil from a biosource with isopropanol.
The IPA/nonrecovered oil/bio solids/water stream from the process is fed to a two-stage falling film evap to recover the ipa with the waste stream off the second stage consisting of 3% oil, 94100 TSS (mg/l), and water.
The oil and the solids are negatively effecting our aeration basin and filter press.
Are there any resources for removing or treating the oil in this waste stream.
Thanks.

I believe you posed this question on the Water and Wastewater Forum.
Contact ECP International, LLC for an effective electrolytic-catalytic system, at water@infoecp.com, or 514-557-4108.

Polypropylene felted media (needlepunch) has a natural tendency to remove oil from aqueous systems. It is a great side benefit when filtering in recirculated wash and rinse systems for machined parts. 10L per element is not a lot, I know, but it may be the reduction you need for oil and TSS . Using an oil skimmer upstream would be a great way to further reduce the oil level.

Would you like to recover the 3% oil or decompose it insitu? Do the solids float or sink?
If the oil and water are in separate phases (not an emulsion), then a simple hydrocyclone density separator will work just fine.
If you want to completely oxidize the oil when it reaches the center of the hydrocyclone see the WhirlArc at:

Regarding the 1/4/2005 post by Bimr, he (and you) should be aware that DAF's rarely provide discharge criteria water on their own. I would also suggest that aeration alone will not sufficiently remove the residual oil and TSS from the DAF effluent, hence my earlier suggestion that you contact ECP International at 514-557-4108 to achieve discharge quality effluent.

A DAF unit is the most cost effective method to remove this oil.
RE: Removing or Treating Edible Oil from Waste Stream
Yes, you are correct that ECP is not a major player in this market....yet! The fact remains that a DAF in almost all cases will not produce an effluent of discharge quality. Therefore additional organic removal treatment will be required to meet discharge criteria....the ECP process is exceptionally capable of doing this.

The inclined plate separator will treat the effluent more cheaply in terms of both running and capital costs that a DAF unit. Both sinking or floating solids and oil can be recovered by such a unit.

Settlement of sludges is allowed for in sizing the tank following the plates.

If you have an installation of edible oils, maybe you can share the details.
