A process for electrocoagulation fluid treatment utilizing a tubular member with a plurality of electrocoagulation assemblies disposed therein. The assemblies have first and second conductive plates that are angularly oriented in relation to one another to promote turbulent flow through the tubular member. A non-conductive block is positioned between the plates to stabilize and orient the plates within the tubular member. The conductive plates may be provided with alternating negative and positive charges to combat corrosion.
