The function of the blower, for this application, is to supply air to one or several tanks in order to bring oxygen to bacteria which degrade the organic matter. To inject this air, the blower must overcome the resistance, or backpressure, due to the water height and diffuser/piping losses.
As the effluent quantity to be treated changes over the course of time, it is desirable to inject only the amount of oxygen necessary and in sufficient quantities to optimise the oxygen needs of the bacteria, thus making it imperative to have the ability to vary the flow while maintaining constant pressure.
The Centrifugal Multistage technology allows variation of the flow by a simple regulation butterfly valve located at the inlet. Energy consumption is therefore in proportion to the actual flow point, thereby optimizing performance and minimiaing power consumption at all operating conditions.
Wastewater treatment plants - Combination of equipments
The Centrifugal Multistage Technology allows to work at the design point with the highest efficiency. The single stage blower can insure the flow regulation while keeping a high efficiency on all its operating range. This combination of Single Stage and Multi-stage blower allow the best compromise Efficiency/Capital Cost.
