Integrated vacuum evacuation of waste foam/gas from an electrocoagulation unit during effluent treatment

摘要

Apparatus and method are disclosed for integrated waste foam/gas evacuation from an electrocoagulation unit. The electrocoagulation unit has a primary electrocoagulation reaction chamber with processing electrodes maintained therein. A flotation chamber is integrated above the reaction chamber and a vacuum hood is affixed over the flotation chamber. A vacuum nozzle device is connectable with a vacuum source and received through the hood and in the flotation chamber, a height adjustable foam intake provided at one end of the nozzle.
