Ozone and oxygen reduce odor at collection system and lift station
Problem
A Pacific Northwest regional wastewater authority received multiple odor complaints especially during summer. Hydrogen sulfide levels ranged from 75 to 250 ppm.
Solution
After a demonstration from Anue Water Technologies, the authority chose a Phantom oxygen/ozone injection system with two HydroSpear conditioning heads in the wet well at the lift station. Pre-demonstration data had shown odors caused by aqueous and vapor-phase sulfides and elevated mercaptan levels.
Result:
Soon after the demonstration began, odors at the lift station vanished and complaints ceased. Hydrogen sulfide levels dropped immediately to single-digits and remained at less than 10 ppm. The decreased odor also reduced blower runtime, saving $2,000
