Many HF flowback fluids have high conductivity, which reduces the power consumption of electrocoagulation processes. The anode is made of iron, aluminum, or an inert metal. In the case of iron or aluminum, the anode is sacrificial and dissolves in the water. At the cathode, hydrogen gas and hydroxyl ions are produced.
