Incineration is a common method of disposal for solid biological material collected during the wastewater treatment process. At our Southerly treatment center, we have begun construction on a new incineration facility to replace aging equipment, conserve resources, generate energy, and reduce air emissions. Out with the old, in with the new Since 1964, Southerly has operated four multiple-hearth incinerators that burn sewage sludge (known as biosolids). It was effective, but used a lot of natural gas.

Incineration and innovation


Our Southerly Wastewater Treatment Center in Cuyahoga Heights incinerates solid biological material collected during the treatment process. We have begun construction on a new incineration facility that conserves resources, reduces air emissions, and generates electricity.

Known as a fluidized bed incinerator, this facility at the Metropolitan Wastewater Treatment Plant in St. Paul, Minnesota, is similar to what will be erected at our Southerly treatment center. Photo credit: Metropolitan Council Environmental Services




FAST FACTS PROJECT Renewable Energy Facility (REF) at Southerly Wastewater Treatment Center CHALLENGE Southerly’s incinerators burn solid biological material collected from two NEORSD treatment plants. Its multiple-hearth incinerators are over 45 years old, nearing the end of their useful service life.

REF CONSTRUCTION 2009–2013 REF BENEFITS • Cuts natural gas consumption by 95% • Saves $1-2 million/year in electrical power costs • Reduces greenhouse gas and regulated air emissions

RENEWABLE ENERGY FACILITY @ SOUTHERLY In 2009, NEORSD broke ground on a new facility that will house three new state-ofthe-art fluidized bed incinerators, which burn biosolids more efficiently. The $170 million project, scheduled for completion in 2013, features many environmentally friendly and cost–effective practices. Some of these benefits are highlighted below. ENERGY EFFICIENT • Fluidized bed incineration uses only 5% of the natural gas needed for multiplehearth incineration, saving approximately $1 million annually.

IT’S NOT THE SUN. It’s a view of the heated sand inside the fluidized bed incinerator that burns biosolids. The incinerator is sealed, but the photograph was taken through a viewing window.

• By capturing excess heat in the incinerator exhaust gases, the process produces high-pressure steam that can operate a turbine to power 25% of the plant’s electricity, saving $1-2 million annually in electricity costs. • The REF has been designed to obtain LEED certification from the U.S. Green Building Council. LEED is an internationally recognized green building certification system. RECYCLING AND POLLUTION REDUCTION • During site preparation in 2009, we recycled concrete and more than 470 tons of structural steel. • Fluidized bed incinerators will reduce greenhouse gas and regulated air emissions.

Construction on Southerly’s Renewable Energy Facility will continue through 2013. For more information, contact Jennifer Elting at (216) 881-6600. LEARN MORE: || FOLLOW US: WATCH US: ||
