New mixing system for the Trenton Wastewater Plant Sludge Storage

completed

In an effort to reduce biosolids production destined for land application, or third party storage, the City proposes the installation of a Linear Motion Mixer in the Trenton Waster Water Plant Sludge Storage Tank. The current mixing system relies on a set of pumps to remove sludge from the bottom of the tank and discharging it from a pipe at the top of the tank. This mixing system has proven inadequate for both biosolids thickening and plant operations. If biosolids production can be reduced by approximately 50% (as estimated by the equipment supplier), this would result in cost savings of approximately $375,000 per year and optimization of the system.
