Oxidation ditch mixers create energysavings in Arkansas
Based on the article by: Louise Davey
“The Landia mixers have been a great investment. In five years, we’ve spent less than $3,000 on spares.”
- Bill Eoff, Wastewater Manager
At the wastewater treatment plant in Huntsville, Arkansas, four energy-hungry rotors were creating more problems than they solved. Faced with rising costs and over-oxygenation, the team needed a solution that wouldn’t interrupt operations.
What followed was a carefully executed shift to sub-surface mixing—and a big win for the city.
CHALLENGE
With four massive 40HP rotors constantly running – and constantly draining both power and budget – Huntsville, Arkansas was caught in a costly cycle of over-oxygenation and maintenance headaches.
SOLUTION
A bold switch to Landia’s submersible mixers – installed without draining the oxidation ditch – allowed the plant to separate mixing from aeration for the first time.
RESULT
The result? A 15% drop in energy costs, virtually maintenance-free equipment, and a plant running smoothly on just 36HP. No loans, no shutdowns – just smart choices and solid performance.
