Old Waste Water Plant Finds New Savings

Old Waste Water Plant Finds New Savings

Recently a water treatment facility in Maine was given an upgrade. Faced with the challenge of little room to work with, engineers ultimately built a plant that uses 40% less energy then the facility previously used.

Some old equipment was retrofitted and reused, in some cases for new application. For example the Package Treatment units were converted into secondary clarifiers. The chlorine contact tank was converted into a sludge pump and disinfection station. To help achieve the reduction in energy consumption, energy efficient HVAC equipment was added to the newly insulated building. Efficient motors equipped with variable speed frequency drives were implemented through out the plant. Automated controls are now used in the treatment process furthering the efficiency of the operation.

Since the implementation of the new plant water quality output from the facility has improved as well. Effluent total nitrogen has been reduced to 8mg/l, and phosphorus levels have been reduced to 1mg/l.
