At Aquafix, our eagerness for fixing every problem in the wide world of wastewater means we encounter some of the strangest situations water can offer. In this new series, Unique Applications, we look at some of our most stand out issues and most inventive solutions.

In 2016, a zoo in the Carolinas inquired about solutions for a buildup of sludge and excess nutrients in three lagoons that recirculate through the elephant exhibit and others. The animal waste runoff had led to declining water quality and excessively high TSS. We sent our microbiologist, Deborah, to the site to measure sludge levels and do nutrient analysis on both the sludge and water column.

Our recommendations led to a treatment plan that involved installing aeration and regular applications of Sludge Rx into the main 11 acre lake to tackle the high volume of waste runoff. In 2018, we returned for follow-up testing to discover major improvements.

Sludge and Nitrogen levels before and after treatment:
Sludge 2016: 14.28 in
Sludge 2018: 2.52 in
Nitrogen 2016: 0.88 ppm
Nitrogen 2018: 0.61ppm

Featured Product

Sludge Rx

The newest technology in biological sludge removal.
Sludge Rx tablets will turn 1 foot of nutrient-filled sludge into a few inches of bacterial biomass. Designed for all types of wastewater facilities, these tablets not only initiate sludge removal but also lower effluent TSS, ammonia, phosphate, coliforms, and effluent pH.
