Electrocoagulation is the process of passing electric current through a liquid, using a variety of anode and cathode geometries, including plates, balls fluidized bed spheres, wire mesh, plates, rods, and tubes.
Electrocoagulation
differences
- Electrocoagulation is a surface reaction. Powell EC engineers for 3,480 square inches per gpm which will accommodate 20 times larger flow rates as compared to other systems.
- Powell EC uses a unique patented electrocoagulation chamber that directly converts incoming AC line voltage to DC voltage. The voltage is set between the blades in the chamber at 3 volts, saving 96% of the electrical costs as compared to other systems.
- Electrocoagulation systems require amperage to treat the water. The amount of amperage draw is dependent upon the conductivity or the water. If the water is not conductive then no amperage will be used. The system should be designed with adequate wiring and electrical capacity to deliver adequate amperage if needed by a particular water stream. Powell EC is engineered for 0.375 amps per square inch or 130 amps per gpm.
- Electrocoagulation creates hydrogen and gas bubbles. The bubbles float vertically. In chambers that have a water flow other than vertically the bubbles collect next to the horizontal surface or corners causing the pressure to build up in the chamber, and creating an insulating factor which stops the current from passing through the water. Powell EC is designed so the bubbles float in the same direction as the water flow.
- Electrocoagulation moves the electrons through the water between positive and negative plates. Positive and negative particles attach to the plate surface magnetically. When the polarity is reversed the magnetically attached particles are repelled into the water flow. The chamber must have sufficient residence time or volume to allow the water to be treated. Powell EC has one-minute residence time in the chamber.
- The blades in the Powell EC accounts for half the dry weight of the system whereas transformers account for most of the weight in other systems.
