Council considers equipment proposal

Wastewater Treatment Specialist John Hinde pitched the idea of implementing his family's Air Diffusion System (ADS) to Carbon Town Council members Monday evening.

"It's energy efficient and improved performance, and I'll give you a five-year guarantee at no cost to the owner," Hinde told council members.

The purposed equipment includes a black plastic header with a small tube port extending perpendicularly from the bottom of the header basin where rubber tubing can be attached connecting the header to a coil of another tube system.

The coil system tubes have "surgical cuts" throughout, allowing air bubbles to escape, which caters to the insects necessary for keeping the wastewater oxygenized enough to control ammonia levels even in cold weather.

Effective Jan. 1, 2009, the State of Indiana added two new criteria standards, which requires a limit of discharge for ammonia and E. coli levels.

Currently, Carbon's waste stabilization lagoons are in violation of the new standards.

Although the violation doesn't pose a threat to citizens, the town is still responsible for solving the issue.

The existing lagoons are not designed to effectively treat ammonia in cold weather.

Council members said the current system meets the state's ammonia standards for the majority of the year, but when temperatures drop during winter months, ammonia levels increase.

Since September 2011, council members expressed they are worried Carbon doesn't have enough funding to meet the water quality standard improvements the state is mandating.

Recently, the council decided to choose the No Action Alternative but are still committed to finding possible solutions.

While considering Hinde's proposal, the council discussed having 15-20 coil systems in two of three lagoon tanks.

"This can all be managed from the shore surface," Hinde said. "You'll be able to cleanse it through the system before it gets into the third cell."

He added the ADS could also solve other problems.

"It's not just a solution for the ammonia problem, but carbon and solids as well," Hinde said.

During the March council meeting, council members accepted a proposal to install a mixing and aeration device, called an Aqua-Manna BOBBER, to nitrify the bacteria in the town's wastewater stabilization lagoons.

Council member David McFaddin made the motion to accept the Bradley Innovation Group's proposal to install bobber devices as part of an experimental study.

Council member Dennis Rightsell gave the second, and Carbon Town Council members voted unanimously in favor to accept the proposal.

Meanwhile, town officials are also seeking assistance from the state through a grant application from the Indiana State Revolving Fund (SRF).

During the April meeting, Wastewater Treatment Plant Operator Doug Clodfelter said Hinde's proposal sounded logical and doable.

"It would strengthen the effectiveness of the carbon-based sewage system," Clodfelter said. "There would be a rock-fixed medium at the end of the second cell. This would be a good back up system to look into if the first one doesn't work."

Clodfelter added if Carbon receives the grant, the allocated funds must be used to install the bobber system, and Town Attorney Eric Somheil said he's optimistic about the grant.

"They haven't committed to it yet, but there's a very good chance we'll get (the grant)," Somheil said.

On Monday, Clodfelter reporter this past winter's ammonia levels met the state requirements, due to an unusually warm season.

The Carbon Town Council meets regularly the first Monday of each month.

The next meeting is scheduled for Monday, May 7, at 7 p.m., in the Carbon Town Hall, 14678 N. Locust St.
