Goal: Decrease Total Suspended Solids (TSS) while increasing Dissolved Oxygen (DO) concentrations in a settling tank
Solution: Installation of a Bottom-up Aerator.
A Bottom-up Aerator works by pumping compressed air down to a diffuser (Figure 1) situated on the bottom of the tank. The air is released through the diffuser as bubbles which work their way to the surface. As the bubbles rise, the oxygen is dissolving into the water.
