One of the biggest expenses in wastewater treatment operations is the cost of energy to run the blowers and compressors that produce air for the aeration basins. The figures most often cited are that 40 to 50 percent of a wastewater plant’s total energy usage can be attributed to the aeration process. By measuring the system’s air flows with accurate, repeatable air flow meters, the aeration process can be better controlled to optimize the process and minimize plant energy cost.
