Project Input Requirements and Importance in Aerator Applications
Aerators are a fundamentally essential process in the efficient treatment of wastewater. The basic function of an aerator is to increase oxygen transfer so that beneficial bacteria can break down the pollutants in the water. The increasing world populations and demands for responsible ecological actions to safeguard our increasing water supply requirements can only emphasize the growing importance of aerators. Aerators account for the largest fraction of wastewater plant energy costs. There are many types of aerator drives and this discussion is limited to vertical, impellerdriven oxidation ditches – as shown in Figure 1 below.
This discussion would be valuable for water treatment personnel, Aerator suppliers, and power transmission suppliers wanting to supply new or replacement equipment and the importance in having accurate demand requirements to provide long-term, trouble free operation of the mechanical components of aerator drive equipment.

The selection of power transmission components, specifically gear reducers for use in aerator drive applications, are a mix of industry requirements, project- specific requirements, and application experience, all of which combine to generate equipment selections. These forces act together with the intention of creating equipment selections, which will operate efficiently and continuously with minimal maintenance requirements. However, one of these requirements may pull or push the equipment selection out of the optimum selection range. Figure 2 is a graphical representation of this typical selection process. When the selection is out of the optimum position, the result is usually premature failure and/or increased maintenance or higher initial cost and long term ROI. Therefore it is critical to the end user and suppliers to provide accurate and realistic load data requirements in addition to environmental and facility requirements.
