Sewage Sludge Management in a Sewage Treatment Plant

Evaluation of Sewage Sludge for Incineration (Case study: Arak Wastewater Treatment Plant)

Sewage sludge treatment has become a primary subject in wastewater treatment and energy production. This paper aims to study the feasibility of power generation by incineration from sewage sludge enriched with impurities like heavy metals. For this purpose, we chose Arak wastewater treatment plant (AWWTP) and used calorific bomb test for examination. The experimental results showed that the hea...

Sewage Sludge Disposal in Switzerland

Sewage sludge was used as fertilizer in agriculture in Switzerland since the begin ning of modern waste water treatment. During the last 40 years several difficulties arose with the agricultural use. The problems with pathogenic germs could be solved with a prepasteurisation. The contamination with heavy metals was reduced during the years but remained a cause for concern. The fear of mad cow d...

Plant Availability of Phosphorus in Sewage Sludge Compost

Field and greenhouse studies were conducted to compare the effectiveness of Blue Plains sewage sludge compost (BLU), Parkway sewage sludge compost (PAR), and triple superphosphate (TSP) as sources of P for corn. These amendments were applied to a Sassafras sandy loam (T> pic Hapludults) in a field study and to the Sassafras soil and a Christiana silty clay loam (Typic Paleudults) in a greenhous...

Renewable Energy from Sewage Sludge

At present, the main contributors to waste to energy are municipal solid waste, manufacturing waste and landfill gas. Probably we are all most familiar with the first (MSW), which involves the garbage that the garbage men pick up regularly at our homes and which goes to a landfill, a transfer station, or incinerator. Today we are going to introduce you to something relatively new on the alterna...
