Abstract
A method of providing sustained odor control in an extended sewer line is disclosed. The method includes measuring at least one parameter of the sewer line including average wastewater volume, flow rate, and retention time and administering a blended composition which includes an immediate release compound and an extended release compound into the sewer line to control concentration of an odorous compound therein. A method of facilitating sustained odor control in an extended sewer line is also disclosed. The method includes providing the blended composition including the immediate release compound and the extended release compound and instructing a user to administer the blended composition to the sewer line control concentration of the odorous compound therein. A system for providing sustained odor control in the extended sewer line including sensors to measure sewer line parameters and a controller to instruct administration of the blended composition is also disclosed.
