Dewatering Performance of Sewage Sludge during the Thermal Compression Process
Sewage sludge proves to be difficult to dewater due to its composition and biological nature, and it is unsuitable for disposal with high moisture content. In the present work, sewage sludge is dewatered by the thermal compression, which shows unique separation advantages of various materials, and the effects of applied temperature and pressure on the dewatering performance are investigated. Th...
متن کاملImprovement of Anaerobic Digestion of Sewage Sludge, Using Combined Hydrogen Peroxide and Thermal Pre-Treatment
The present study investigates the influence of individual and combined hydrogen peroxide and thermal pre-treatment of waste activated sludge on anaerobic digestion. For so doing, it employs anaerobic batch reactors in the mesophilic conditions. For comparison, soluble fractions of organic matter, biogas production, biochemical methane potential, removal of chemical oxygen demand (COD), and vol...

متن کاملInvasion of Tomato Roots and Reproduction of Meloidogyne incognita as Affected by Raw Sewage Sludge.
The antagonistic effects of raw sewage sludge on infection of tomato by Meloidogyne incognita were tested in greenhouse pot experiments. Sludge was mixed with the soil or added on its surface before and after inoculation of tomato plants with nematode eggs. Juvenile penetration was determined 1 and 10 days after inoculation, and 6 weeks later root systems were assessed for nematode reproduction...
متن کاملThermal Gasification of Densified Sewage Sludge and Solid Waste
Disposing of sewage sludge in an economical and environmentally acceptable manner is a problem for all communities that have wastewater treatment plants , Similarly , many com munities are having to dispose of increasing quantities of solid waste. These problems could be solved by co-disposal of sludge and solid waste in a common facility. This study , .‘nvnH .. -- au &LLnAE -' .‘maLnH .. o...
