Hi Catia It is not a bad idea to use CF to reduce the organics but must be careful with the type of carbon that you use, also the system (tank, diffusers, piping etc.) must be designed to be sanitized with steam, just like in the dairy industry, also the Carbon media must be replaced more frequent that usual, hard to tell now because it depends on the maintenance that the operators give to the system, best case scenario would be 12-18 months. I think your best bet is to use a membrane that can be sanitized with hot water such as the Hydracore 70 manufactured by Hydranautics, I’ve used those membranes to concentrate cheese whey and although they need to be cleaned every day, they do a pretty good job reducing COD from about 100,000 to less than 2000 with a concentration factor of x3, which is a 98+ % COD removal. However, I will recommend you to run a pilot, especially with the type of water that you are dealing with. I hope this help you, if you are used to a different brand of membranes, I am sure that DOW will have an equivalent to the Hydranuatics Hydracore. If you need more information, I will be happy to share it with you. Good Luck Luis Inarejo
