Choice Ballast Solutions (Choice) collaborates with Ecochlor Inc to provide solutions for the installation arrangement of BWMS on tankers. The Ecochlor system includes filtration followed by a side-stream injection of a dilute solution of chlorine dioxide. During ballasting, the full flow discharge from the ballast pumps must be treated with the filters. The chlorine dioxide is injected into the ballast water downstream of the filters. No further treatment is required on de-ballasting. Successful installation arrangements were developed on tankers with a pump room, tankers with submerged pumps and on tanker barges.
