Sulfate Removal
Apex Engineering designed and helped install two biological sulfate removal systems at closed mines for Kinross Gold in Washington State.  I have also evaluated the Cost-Effective Sulfate Removal (CESR) process for sulfate removal, which is a chemical treatment system able to achieve very low sulfate concentrations under most conditions.  Click on each project title or picture to see more information on that project, and click on the company name to go to that website.
