Blending form and function- Digesters play a critical role in processing sludge, the organic material removed from sewage. Inside the digesters – given heat, lack of oxygen and time, bacteria break down the sludge into more stable materials. This natural process converts much of the sludge into water, carbon dioxide and methane gas, leaving what is called “digested sludge.” This material, in turn, is dewatered to form a cake, which, after additional processing, can be used as fertilizer.
