Plant/Process Description:
The original plant became operational in 1953 and many of the treatment units remain in use today. The first treatment equipment consisted of a pump station, flow meters, four clarifiers to physically remove solid materials from the waste stream, and two sludge pumps. Two Anaerobic digesters (Primary and Secondary) were used to biologically reduce the organics in the solids that are removed as part of the treatment process.

Sludge drying beds were used to dewater and dry treatment residuals. The final treatment process involved the addition of chlorine gas to kill pathogenic organisms before the treated wastewater was discharged to the Thunder Bay River. The plant removed about 15 to 20% of the pollutants that entered the facility.

In 1972, the plant was upgraded to improve pollutant removal capability. Using grant funds from the USEPA, secondary treatment was added to the facility. A biological treatment process called Activated Sludge was used to enhance removal of dissolved pollutants from the wastewater. This addition improved pollutant removal rates and the plant regularly achieves 90 to 95% pollutant removal efficiency.

Any wastewater treatment process generates solids that must to stabilized and recycled. Two 300,000- gallon anaerobic digesters are used to treat the solid material generated by the Alpena Water Recycling Plant. The digesters are similar to a septic tank, except modifications are made to the process to speed up the bacterial activity. The primary digester is heated to between 90 and 100 degrees F and the contents of the tank are mixed using compressed digester gas.

A valuable byproduct of the anaerobic digestion process is methane gas. This energy source is used to fire the plant boiler and fuel a 4- cyclider engine that drives a raw wastewater pump. Utilization of methane gas from the digester saves the Utility about $15,000 in energy costs.
