I would only add that if you Are going to use a coagulant, then when you’re doing your Jarred testing definitely monitor the pH, but also the ORP. The ORP is significantly indicative as his pH of which Coagulants are going to work best. By changing the ORP to a higher value, you can get a better break with much less coagulant/flocculant.  The use of hydrogen peroxide to enhance coagulation has been used in many applications, Especially if you have some iron in the water to work with already. It may take 15 to 20 ppm of Ferric For the mechanism to work properly. Just a thought. I’ve only had experiences with Dairy waste in 5 facilities.  Also as mentioned below you do need a surge tank prior to your DAF to regulate organic loading, pH and hydraulic swings or you will be chasing your tail.  Lots of good comments though!
