Ammonia Reduction In Trickling Filter
Domestic Wastewater Treatment Facility

Biological Treatment Summary

The Situation

A major municipality faced the problem of elevated levels of ammonia in its discharge water. In order to meet regulatory limits the facility had to divert its wastewater to a neighboring municipality at a very large expense.

The Solution

In conjunction with the facility, an in-plant, full scale feasibility study to determine the effects of Aquaculture on ammonia reduction when applying Aquaculture in their trickling filters only.

The Results

The project data clearly demonstrated the ability of Aquaculture to reduce the ammonia levels when the trickling filters were treated. Due to the treatment program the facility was able to treat a larger volume of water and keep the discharge water within regulatory permit levels.

The treatment program will save the facility hundreds of thousands of dollars by the facilities ability to treat more wastewater on-site versus the costs of diverting the wastewater to another facility.
