ABSTRACT:
A process and apparatus for biologically treating water. The inventive process preferably comprises the steps of: (a) adding a sulfur-containing oxygen scavenger to the water in an amount effective for at least reducing the amount of dissolved free oxygen contained in the water; (b) removing at least a portion of a substance from the water by exposing the water to microorganisms effective for biologically removing the substance therefrom; and (c) feeding a biostimulant to the microorganisms effective for increasing the rate at which step (b) occurs. The inventive apparatus preferably comprises a system for adding the sulfur-containing oxygen scavenger to the source water stream and a system for feeding the biostimulant to the microorganisms.
