May 2018 Tour of Greater Lawrence Sanitary District (GLSD) Organics to Energy Project

 

The Wastewater Advisory Committee and friends tour the Greater Lawrence Sanitary District Co-Digestion Project.

 

Food slurry is loaded into the tank, GLSD

 

Digesters at GLSD are squat and round--they have four.
All four can take food waste slurry along with sludge.

 

Gas from the digesters is cleaned of Siloxane and Hydrogen Sulfide before being burned.
The tanks here contain wood chips treated with iron oxide and carbon to remove each of these compounds.

 

GLSD Capital Projects Manager Richard Weare and
Advisory Board Chair Lou Taverna check out the intake for the food slurry tank.

 

GLSD Manager Weare shows off the new engines at the combined heat and power plant.
GLSD could produce 100% of its own energy at 92,000 gallons/day of food waste slurry.

 

WAC members inspect the engines.
