Some examples of lagoon upgrades include:
- Adding advanced aeration & mixing which reduces short circuiting, anoxic zones, and maximizes biological activity. I am especially interested in new microbubble/nanobubble technologies that improve oxygen transfer with less utility costs.
- Opportunity to enhance performance by adding MBBR into lagoons. The MBBR media develops biofilm that remains suspended in the lagoon and treating pollutants. If you see this as lowering the F/M or increasing MCRT for microbes in the system, you are correct.
- Installation of smaller advanced treatment modules to remove ammonia or phosphorus while using the lagoon for primary BOD/COD reduction.
