If your intention is to use a DAF and your question is to use EC as a post treatment, I would suggest EC to be a pre-treatment. EC will remove silica and add hydrogen to the water which will aid in the floatation of the particles. It will also assist in the separation of the oil which help the float. There are sodium bentonite clay blends that can assist in the agglomeration of the separated substances and provides for better dewatering characteristics.
