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 کاملEffect of electrolytes content on the electro-osmotic dewatering of agro-industrial sludge
The agro-industrial sludge, tested in this work, comes from a biscuit factory (France). Initially, it contains 3 % w/w of dry matter. The actual treatment by centrifugation dewaters it to 13 % w/w of dry matter. Electroosmotic dewatering under pressure (EOD) was investigated, as an alternative technology of mechanical treatment, to improve dewatering. This electrical treatment efficiency depend...
متن کاملImpact 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 کاملEffects of Cationic Polyacrylamide Characteristics on Sewage Sludge Dewatering and Moisture Evaporation
The effects of the molecular weight (MW) and charge density (CD) of cationic polyacrylamide (CPAM) on sludge dewatering and moisture evaporation were investigated in this study. Results indicated that in sludge conditioning, the optimum dosages were 10, 6, 6, 4, and 4 mg g(-1) CPAM with 5 million MW and 20% CD, 5 million MW and 40% CD, 3 million MW and 40% CD, 8 million MW and 40% CD, and 5 mil...
متن کاملthe effects of planning on accuracy and complexity of iranian efl students’ written narrative task performance
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
