Wastewater and Water Aeration Systems- CLEAN-FLO

In designing our first wastewater aeration system, we tackled all of the toughest problems. Because of the energy crisis, the wastewater aerator had to be the finest bubble bottom diffuser available. However, it also had to be non-clogging and more efficient than wastewater surface aerators. Furthermore, it had to remove odor and bottom organic sediment (muck). To achieve these goals the CLEAN

Aerated Lagoons: 5 Design Factors To Consider

24/07/2015 Moreover, the purpose of aeration in a wastewater lagoon system is more than just to add the necessary oxygen to water: it is also to mix. Mixing ensures that the organic matter, bacteria, and oxygen all come into contact with each other, thereby facilitating the wastewater treatment process.
