Impact of Conditioning Substances and Filtration Pressure on Dewatering Efficiency of Sewage Sludge
نویسندگان
چکیده
Sludge dewatering is a key element in sludge’s processing and management. Solid-phase separation, sludge volume reduction the separation of high-quality supernatant are main tasks devices. The effectiveness this task, turn, results from selection method conditioning before dewatering. aim research was to determine influence substances (polyelectrolyte, fly ash zeolite) on efficiency at variable filtration pressure. use polyelectrolyte solution that increased process. On contrary, structure-forming (fly slows process but reduces hydration filter cake. same trends were obtained dual combining dosing or zeolite. It also shown conditioned with these two different (ash same. zeolite independent important for quality supernatant.

Impact of sewage sludge conditioning and dewatering on the fate of nonylphenol in sludge-amended soils.
The fate of (14)C-labelled p353-nonylphenol (NP) in soils amended with differently treated sludges originating from the same precursor sludge was assessed. The effects of commonly applied conditioning and dewatering techniques were investigated. Nonylphenol was degraded considerably faster in soils amended with liquid sludge, while a significant portion of it remained intact and extractable by ...
متن کاملEnhancing the MTE dewatering of sewage sludge by conditioning with brown coal
Dewatering of sewage sludge is an important part of proper sludge management practice. It is becoming a more challenging issue for water industries as new regulations on sludge disposal are being imposed. In this paper, the application of mechanical thermal expression (MTE) to dewater sewage sludge and the conditioning of sludge by mixing with brown coal are investigated. Raw sludge, sludge flo...
متن کاملDewatering 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...
