You can use a DAF (dissolved air flottation) combined with chemical floculation or a MBR (membrane bioreactor).
You should have an analysis of your water to determine the complete required process you need.
Hello Tamie and thank you for your response to my inquiry,
Can you recommend any firms in Canada or the USA who might be qualified to perform the required water analysis and design the appropriate WWTP systems?
Thanks in advance,
If you send me a private message to let me know where you are exactly I may give you few refenrence in your area. Some that I know only work in the area they are located. You can at least contact some companies like Veolia, Suez, operating all over Canada and the USA who can help you with hydrocarbons treatment for sure. Those 2 are usually able to take samples, then send them to a certifiez lab, recommand treatment and also supply them.
Sent you a PM
