Have you ever been on a plant and hear that high pitched whining coming from the blowers or blower building? 

That sound is old inefficient aeration blowers with little to no control. These blowers are one of if not the one technology on the wastewater site that eats the most power and they usually don’t have a way of turning down and run at 100% all the time. Twenty years ago these were great workhorse blowers and they did the job, but technology has changed for the better.  

The main issue with old blowers is that they are designed to run at 100%. 

If you know wastewater you know that that is not what is needed. Wastewater treatment has a sweet spot that and chasing that is the key to great treatment. If you have a blower that has no flexibility to run at low speed or high speed then you are just turning it on and off trying to hit a moving target. The newer blowers can operate on a range and maintain an operational air demand standard therefore there is no waisted energy.

Kaeser’s Air Demand Analysis (ADA) is a tool we use to determine what we can do for your installation. 

The ADA works by having a trained technician visit the plant and apply sensors on your current blowers to determine the air that is being produced along with the power consumption.  Kaeser will take all this data and put it into a report showing what the current blowers are producing and at what cost. They then take at the application design and determine what Kaeser blower(s) best fits the application that is both air and electrically efficient. This same report will compare the current blowers and the Kaeser option side by side and show how the old blowers can be replaced and paid off by the power savings of the new blowers. In some cases, the Return On Investment (ROI) can be just a few years.  We have some reports that we can show you how things work and are a good example of what your report can be.  

The beauty of having new blowers that can be paid off in a few years by the power savings is the next 20 years or saving money.  These savings can be used to upgrade other parts of the plant that have been overlooked. Just give us a call and we can start the conversation to plan your ADA today.
