Project
HRRSA North River Wastewater Treatment Plant Enhanced Biosolids Reuse & Reduction
north river
This Enhanced Biosolids Reuse and Reduction (EBRR) project consisted of the construction of a biosolids dryer facility with external support systems and upgrades to existing plant facilities. The purpose of the project was to significantly reduce the amount of biosolid storage required by producing a class A biosolid. This project was completed ahead of schedule in October 2019 and was recognized by the EPA with a 2018 PISCES award. It is also a Gold Medal Winner of the Governor’s Environmental Excellence Award.

Project Details
The system utilizes renewable energy by fueling the dryer with biogas produced by the plant’s existing anaerobic digestion process—prior to the project, excess gas was wasted via a waste burner. The new heat recover system also converts and returns dyer of-gas heat to the plants digestion process. The project included demolition in the biosolids storage pavilion to make way for the new Dryer Building. The Dryer Building, which was built under an existing metal building, is a split-level 5,300 SF CMU building that houses the biosolids dryer equipment. The dryer equipment consists of a 40-ton Komline-Sanderson paddle dryer and several auxiliary systems such as: feed, conveyance, classification, thermal fluid, heat recovery, biogas boosting, compressed air, sump discharge, odor control, utility water, and associated piping, electrical, and controls.
