Mazzei Aeration System Solves Lagoon Odors and High Maintenance Problems
Sleepy Eye, MN

The Problem: A large vegetable processing facility in central Minnesota was experiencing problems with its lagoon surface aerators. The company’s treatment process includes a collection and screening assembly, two anaerobic stabilization ponds and a 40 million gallon aerated lagoon. The aeration lagoon is
used for BOD reduction and polishing before the water is discharged to a near-by creek. Several surface aerators had been used to provide the oxygen in the aeration lagoon. However, the surface aerators were beginning to fail causing odor issues. This, along with ongoing high maintenance requirements, prompted the company to seek a new method for lagoon aeration.
