Pulp and paper wastewaters contain significant concentrations of sulfate. If aerobic conditions are not maintained in wastewater treatment systems by adequate aeration (oxygen transfer) and mixing (to avoid isolated and stagnant areas,) bacteria will switch from elemental oxygen to sulfate as an electron acceptor. In such a reducing environment, hydrogen sulfide is generated. Surface aeration that employs splashing or spraying wastewater into the air to increase oxygen transfer also can strip hydrogen sulfide from the solution (depending on pH), resulting in emission of H2S into the air, odor complaints, and increased metal corrosion. Control odor generation and release into the air with the Aire-O2 Triton® Process Aerator and Mixer.
The Aire-O2 Triton provides high oxygen transfer efficiency per hp hr via subsurface, fine bubble aeration, and deep mixing; with no risk of surface splashing and aerosolized H2S.
