Lagoon Expansion
Lagoons typically have more than enough hydraulic capacity to be expanded.
You just need to teach that old dog new tricks.
Expanding capacity is as simple as increasing mixing
- The level of mixing in your lagoon determines how well the metabolizing microorganisms come into contact with the food (BOD).
- As a result, the level of mixing determines how much can be treated and how quickly.
- The higher the mixing rate, the faster the treatment.
Adding baffle curtains alone can increase treatment capacity.
- Floating baffle curtains improve hydraulic retention time by forcing water to travel longer distances. This improves treatment.
- If aeration is used, the baffle curtains create different treatment zones, thereby improving overall treatment kinetics.
Combine mixing improvements with baffle curtains to optimize treatment.
- Baffle curtains create different treatment zones within an aerated lagoon.
- The higher the mix rate within a zone, the higher the treatment.
- The number of zones and their mixing rates can be modeled and optimized to minimize the cost of expanding capacity while meeting water quality effluent objectives.

LRAS Process
Need to go big? Expand capacity 10x with LRAS.
- Triplepoint’s LRAS® (Lagoon Return Activated Sludge) is a lagoon/mechanical plant hybrid.
- A complete-mix lagoon receives influent flow. Secondary clarification and return sludge from clarifiers creates a mixed liquor in the lagoon.
- LRAS expands a lagoon system by 10x its original rated capacity within the same footprint.
