ELECTROCOAGULATION APPARATUS HAVING INTEGRATED CLARIFIER

1 . An electrocoagulation apparatus for effluent treatment comprising:

a clarifier having at least a first tank; and

an electrocoagulation reactor positioned in said first tank of said clarifier and including an effluent inlet and outlet to said clarifier apparatus.

2 . The apparatus of claim 1 wherein said reactor includes a primary reactor chamber associated with a first part of said outlet and a sludge chamber associated with a second part of said outlet.

3 . The apparatus of claim 1 wherein said clarifier is a plate clarifier.

4 . The apparatus of claim 3 wherein said clarifier includes a second tank receiving separated effluent from said first tank and semi-clarified effluent from said electrocoagulation reactor outlet.

5 . The apparatus of claim 1 wherein said reactor includes primary and secondary reactor chambers in fluid communication with one another, each housing an electrode or electrodes.

6 . An electrocoagulation apparatus for effluent treatment comprising:

a plate clarifier having a first tank, a second tank receiving separated effluent from said first tank, and a sludge concentrator with an output; and

an electrocoagulation reactor positioned in said first tank of said clarifier and including an effluent inlet, a sludge chamber and output to said sludge concentrator of said plate clarifier, and an outlet to said second tank of said plate clarifier.

7 . The apparatus of claim 6 wherein said reactor includes a primary reactor chamber associated with said outlet and positioned above said sludge chamber.

8 . The apparatus of claim 6 wherein said electrocoagulation reactor includes a floatation chamber for foam/gas accumulation and removal.

9 . The apparatus of claim 6 wherein said plate clarifier is a lamella plate clarifier.

10 . The apparatus of claim 6 wherein said reactor includes plural reactor chambers.
