You don't mention the flow. I am guessing it to be fairly high. The COD is probably tied up in some type of emulsion that the DAF can't break. Vacom has an MVR evaporator that can do the job but the capital cost is quite high. The evaporator would also take the place of the UF and RO if the flows make sense (not too high). The Vacom evaporator can process up to 80-100,000 gpd for about $4,500,000. If this isn't practical or it is too expensive, you can go back to a "knowledgeable" DAF manufacturer and see if they have some type of chemistry that will break the emulsion. I don't know of anything else that might help you.
