| When
dairies utilizing lagoons for wastewater treatment seek to
co-exist with urban development, odor is often an area of
concern. THE O2 SOLUTION® System can be a key strategy
for a dairy facing this challenge … virtually eliminating
odor and solids build-up in the lagoon.
The Operation
A 1,500+ head
dairy on 60 acres of land near Wellington, Colorado. The
town is downwind less than one mile.
The dairy has
four loafing sheds, from which effluent is flushed into
one of two settling ponds. Liquid is drained off and pumped
to an eight-acre lagoon. Treated water is pumped from the
lagoon and used to flush fresh effluent back into the system.
Solids
are periodically removed from the settling ponds and then
composted on site.
The Challenge
This dairy began
receiving odor complaints from its urban neighbors. After
reviewing a number of alternatives, they decided to go with
THE O2 SOLUTION® System. A six-tank facility was installed
at the lagoon site.
While this dairy has an arrangement with a local farmer
to utilize the dry composted material, there is no opportunity
to “dewater” the lagoon. There is no transferring
of liquid nutrients to other land.
To illustrate the scope of the water treatment challenge
here, it should be noted that between 250,000 and 400,000
gallons of water are pulled from the lagoon each day and
recirculated through the barns for flushing.
THE O2 SOLUTION® System Results
Within 90 days, results have been dramatic. Odor has been
virtually eliminated. Dissolved oxygen levels at a depth
of six feet are approaching 1.0 mg/Liter.
