often used. Nevertheless, the high water content in the sludge makes sludge management costly and can stand for up to 65% of the total operating costs at paper mills.19 Paper mill sludges are basically composed of organic matter (mainly cellulose fiber from wood or recycled paper) in which organic compounds are added to the paper or pulp while
2004/12/13/ · This chapter is focused on the problem caused by the effluent discharges from paper and pulp mills. At present, three aspects should be considered in paper and pulp wastewater management: (1) the toxicity and high BOD5 of whitewaters and effluents; (2) the lack of knowledge on specific compounds responsible for the toxicity of the liquid and solid
2024/4/30/ · The relevant studies will provide new sights into sludge fermentation and guidance for sludge disposal. We are inviting research papers and reviews about novel insights on sludge fermentation. The aim of this Special Issue is to provide an insight into the latest findings of sludge fermentation, including the biologically volatile fatty acids
2022/1/5/ · Sludges from pulp and paper mills represent a major ecological and environmental cost, and anaerobic digestion represents a method of waste reduction and
2024/1/2/ · Paper mill sludge (PMS) mitigated inhibitory effect of furfural in black liquor (BL). • PMS improved H 2 yield from the BL by 8.3-folds and accounted for 2.1 mol/mol glucose.. e – eq transferred to H 2 was 9.3% in the PMS:BL, 7.4% in PMS, and 1.27% in BL.. Acinetobacter degrading furfural (6.1%) was abundant with PMS addition.. Bacilli (8.9%)
2023/7/15/ · The implementation of a side-stream sludge fermenter (SSSF) has been identified as a possible solution to improve the performance of an anaerobic/anoxic/aerobic (A 2 O) configuration when treating low COD wastewater. This study systematically evaluated the effects of incorporating a SSSF into an A 2 O configuration (side-stream enhanced
Previously paper mill sludge was not suitable for biogas production due to its cellulose content. The material caused crust formation in biogas digesters and hard to digest cellulose did not release enough nutrients for biogas production. According to pilot studies, it is clear that 60% of the organic matter in the paper sludge is converted ...
2021/6/1/ · The study aims to investigate the feasibility of anaerobic co-landfilling of effluent treatment plant sludge (ETPS) from paper mill and municipal solid waste (MSW) in prismoidal shaped simulated anaerobic landfill bioreactors. Both ETPS and MSW were co-disposed in 0:100 (R1), 25:75 (R2), 50:50 (R3) and 75:25 (R4) ratios.
2021/1/20/ · Paper mill sludge (PMS) is a cellulosic by-product typically used on animal bedding and land spreading. The material has been dissolved in an ionic liquid - 1-ethyl-3-methylimidazolium diethyl phosphate - with the aid of a co-solvent dimethyl sulfoxide (DMSO) - and spun into continuous filaments for textile production .
2024/1/26/ · Due to the organic content, the landfilled paper mill sludge is subject to aerobic and anaerobic decay. Theoretically, when landfilling 1 ton of low-ash paper mill sludge (<30% ash), approximately 2.69 tons of CO 2 and 0.24 tons of CH 4 are released into the environment . SPS volumes are lower than those corresponding to the PS, since most of
2019/7/15/ · Characterization of solid wastes is an important to analysis of the final disposal. •. Chemical, thermal, mineral, physical and environmental conditions were evaluated. •. Waste from the paper industry is classified as non-inert non-harmful; •. The best disposal methodology from the paper industry waste is sanitary landfills.
2024/2/1/ · Source and primary characteristics of waste sludge. The raw sludge used in the experimental tests was obtained from a SPTs in Nanjing, China, and was filtered by 1 mm sieve and quickly transferred to 4 °C for storage before further experiment. The primary characteristics of the raw sludge were determined (Table 1). Experimental procedure
2016/3/1/ · The mill sludge accounts for the main waste from pulp and recycled paper production. Pulp and paper mill sludge is an organic residual generated from wastewater treatments (Faubert et al. 2016
2011/9/29/ · Background Ethanol production from paper sludge (PS) by simultaneous saccharification and fermentation (SSF) is considered to be the most appropriate way to process PS, as it contains negligible lignin. In this study, SSF was conducted using a cellulase produced from PS by the hypercellulase producer, Acremonium cellulolyticus C-1 for PS
2021/8/1/ · Experimental studies are conducted with streams from three different pulp and paper mills (virgin pulp mill (VP), corrugated recycling mill (CR), tissue printed recycling …
