Air supply is critical in many industries, sometimes surprisingly. Water treatment facilities are not the first buildings where one would expect air supply to vastly affect efficiency.
In water treatment plants for the Rubiera system, the process is built into four parallel pipelines, and compressors are used during the oxidization and nitrification portions of the process. The initial setup used compressors rated for much more capacity than was required by the facility, and as such the process was over-supplied for long periods of the day.
“The first step was to change the set-up, linking all the machines together. It was seen, in fact, that it would have been sufficient to use only one compressor for generating the process air during the period of less demand, but that compressor had to be very versatile and offer a wide range of capacity variations.”
