Ammonia Reduction Through Bioaugmentation - Domestic Wastewater Lagoon

Biological Treatment Summary

The Situation

A domestic wastewater lagoon was facing compliance problems with levels of ammonia leaving the lagoon. Discharge levels were averaging 14 mg/L with highs in the low 20's. Their discharge permit levels were 2.0. The lagoon was receiving notices of violation from the state's regulatory agency.

The Solution

United-Tech proposed a bioaugmentation program that consisted of the addition of BZT® Aquaculture to the wastewater lagoon. It was proposed that an initial seed application be performed followed by regular weekly maintenance applications.

The Results

Prior to the start of treatment, the ammonia level was 16.3 mg/L. Twenty-four (24) hours after the initial seed application, ammonia levels were measured to be below 2 mg/L.

Today, almost two years later, the ammonia levels in the lagoon are constantly below 1 mg/L.

The lagoon continues to follow a maintenance program utilizing BZT® Aquaculture with ammonia levels approaching non-detectable.
