The present invention provides an improved method and apparatus for removing dissolved selenium from a wastewater solution. The apparatus (10) treats heated selenium containing solution in a single, flow-through operation by employing both the anode chamber (30) and cathode chamber (32) of an electrolytic cell and a series of sub-micron filters (36, 42). In operation, the present invention has proven to be very effective in treating selenium containing solution to meet or better the government toxicity characteristic specifications of 1 ppm.
