The wastewater treatment plant superintendent for a rural Colorado town of about 500 people noticed that the plant’s three wastewater lagoons were filling with sludge, but he was dealing with budget constraints. The town’s population fluctuates throughout the year, and the varied loading was affecting system performance. In addition, the aeration systems were not keeping up with the oxygen demand in the ponds. The superintendent decided to try a bioremediation approach to sludge reduction, using BIO ENERGIZER®, before embarking on the expensive process of mechanically dredging, hauling, and disposing of the sludge.

Using BIO ENERGIZER® is now saving the city thousands of dollars in mechanical dredging, hauling, and disposal costs. Lagoon desludging using BIO ENERGIZER® is typically one-fifth to one-tenth of the cost of mechanical dredging and land-applying or land-filling sludge.
