Many aeration systems involve “splashing”, or sending the wastewater into the air in a fine mist in order to increase the dissolved oxygen (DO). This is an inadequate way of increasing DO for two important reasons.
The first is that it is less effective. The goal is to put air into the water, not water into the air. A fine mist of water does not absorb as much air as can be injected by a system that pulls it in with a vacuum like the Aire-O2 Aspirator does.
The second reason is sulfur compounds and volatile organics (VOCs) are put into the air by splashing systems. The resulting stink is not only undesirable, it may violate air quality standards on the job site.
