Protein Extraction from Secondary Sludge of Paper Mill Wastewater and Its Utilization as a Wood Adhesive
In this study, secondary sludge (SS) from a kraft paper mill was used as a source of biomass to recover protein and investigate its potential use as a wood adhesive. The process of protein recovery involved disruption of the floc structure in alkaline medium to disintegrate and release intercellular contents into the aqueous phase followed by separation of soluble protein. Finally, the soluble ...
متن کاملTreatability Studies on Hybrid Up - Flow Anaerobic Sludge Blanket Reactor for Pulp and Paper Mill Wastewater
In India, Pulp & paper industries have been large uses of portable water and consequently large generator of waste water. Anaerobic treatment of paper processing waste water has a distinct advantage of recovery of inherent energy in the form of methane gas with much less sludge production. A hybrid reactor that capitalizes on the positive features of anaerobic filter(AF) and up-flow anaerobic s...

متن کاملCharacteristics and disposal options of sludge from a steel mill wastewater treatment plant
In the present study, sludge from a steel wastewater treatment plant (SWWTP) was analyzed regarding its physicochemical characteristics and metal contents, and disposal options. For these purposes, grab sampling was used to collect 18 slurry and 18 cake sludge samples in 6 mouth (May-October 2012). Mann-Whitney U test, one sample T-test and Wilcoxon signed rank test were applied to analyze the ...
متن کاملEffect of Metal Salt Coagulants on Treatment of Activated Sludge Effluent in Sulfite Mill Pulp and Paper Plant
Pulp and paper effluents are considered as serious environmental hazards and their treatment, because of multiplicity of impurities and complexity of their chemical structures, is one of the most difficult and inconvenient industrial processes. As the most pulp and paper mill work on kraft process, there are few studies in literature on the treatment of neural sulfite semi chemical (NSSC) p...
