Abstract
Process for treatment of wastewater is provided. The wastewater includes suspended or dissolved wastewater components and an aqueous component. During the treatment process, at least a portion of a solids bed through which the wastewater is passed is dissolved using an electric current. Dissolution of the solids bed produces constituents which react with the wastewater and enable separation of the suspended or dissolved wastewater components from the aqueous component. Also provided is a system for carrying out the process.
Claims23
A method for treating a wastewater stream, the wastewater stream including suspended or dissolved wastewater components and an aqueous component, the method comprising:
- providing a solids bed including at least partially electrically conductive particles;
- locating at least one pair of spaced electrodes within the bed;
- flowing the wastewater stream through the solids bed;
- passing an electric current through at least the at least one pair of spaced electrodes to thereby dissolve at least a portion of the solids bed to produce dissolved constituents which react with the wastewater stream to enable separation of the wastewater components from the aqueous component;
- and
- removing the separated wastewater components from the aqueous component.
A system for treating a wastewater stream, the wastewater stream including suspended or dissolved wastewater components and an aqueous component, the system comprising:
- a reactor having an inlet and an outlet and adapted to receive the wastewater stream;
- a solids bed located within the reactor, the solids bed including at least partially electrically conductive particles;
- at least one pair of electrodes located within the solids bed in a spaced apart relationship;
- and
- an electric current source operatively coupled to the reactor, and wherein
- during operation, an electric current generated by the electric current source dissolves at least a portion of the solids bed to produce dissolved constituents which react with the wastewater stream to enable separation of the suspended or dissolved wastewater components from the aqueous component.
