CH#1138 - Anaerobic Digesters

Waste Type: Fats, oils and grease (FOG) in Anaerobic Digesters Problem: FOG waste poses a challenge for most municipal wastewater collection systems and treatment plants. Although fats, oils and grease will biodegrade in an anaerobic digester, high concentrations will tend to 'mat' on the sludge surface, lowering digestion efficiency. This Midwestern municipal facility was no different. The 1.5 ...

Bio-fuels- Anaerobic digestion

Anaerobic digestion is a series of processes in which micro organisms break down biodegradable material in the absence of oxygen. It is widely used to treat wastewater sludges and organic (agricultural) wastes. As part of an integrated waste management system, anaerobic digestion reduces the emission of gas into the atmosphere. Anaerobic digestion is a renewable energy source because the ...

High dry solids digestion

ABSTRACTDigestion of sewage sludge normally takes place at pH values between 7,0 and 7,5. Control methods of the process stability are based on practical experience such as the ratio of volatile fatty acids (VFA) and total alkalinity (TA). Thermal sludge disintegration for an enhanced digestion process allows a digester feed with higher dry solids concentrations. This is due to an opening of ...
