Three phase elctrocoagulation effluent treatment apparatus and methods

摘要

Electrocoagulation effluent treatment apparatus and methods are disclosed, the apparatus including a primary electrocoagulation reactor chamber having treatment electrodes maintained therein and an effluent inlet and treated effluent outlet. An integrated flotation chamber is located above the reaction chamber, a vacuum device connectable with a vacuum source being received in the flotation chamber and including a foam intake and an output. A sludge chamber is defined below and integrated with the primary reaction chamber and has a settled sludge output.

主权项

1. A method for treatment of effluent comprising the steps of:
separation of light flotation solids in foam, gas, oil and grease layers to a treatment effluent surface in a chamber; applying a vacuum at the surface for removal of the light flotation solids in foam, gas, oil and grease layers from the chamber; treating the treatment effluent below the surface in the chamber using electrocoagulation processing; removing electrocoagulation treated effluent from the chamber; precipitating solids out of treatment effluent in the chamber; and periodically flushing solids from the chamber.
