2023/10/1/ · However, no studies are available investigating paper mill lime waste addition in MSW landfilling scenario. Lime sludge (LS) from paper mill has exclusively high pH (∼10.5 – 12.4), highly alkaline, fine powdered, low dense (density ∼ 0.74 g/mL) by-product of causticization process of alkali recycling step performed in a paper mill (Haile
2019/6/1/ · In this study, four bioreactors, including a sequencing batch biofilm reactor (SBBR), a stirred-tank reactor (STR) and two submerged aeration reactors (SAR) were used to treat secondary effluent from a recycled paper mill respectively. The results indicated that chemical oxygen demand (COD) was increased by SAR2 treatment and COD removal
2022/12/1/ · The treatment plant's return sludge pipeline is where the biomass was obtained [28]. Utilizing Peristaltic Pump Silicone Tubing by Longer Pump, influent PPIW was constantly fed into the reactors at a rate of 5 L/d. Pulp and paper industry effluent generation and its treatment in a bench-scale ASBS is depicted in Fig. 2. Long-term aeration was
2010/1/23/ · Paper mill sludge is a solid waste material composed of pulp residues and ash generated from pulping and paper making processes. The carbohydrate portion of the sludge has chemical and physical characteristics similar to pulp. The sludge was loaded into the bioreactor that the initial glucan content in the reactor becomes 1% (w/v). Sludges ...
2017/4/15/ · Paper mill sludge (PMS), a lignocellulosic waste from paper industry, is an ecological burden of environmental concern. Present study explored PMS as substrate for prodigiosin production in solid state fermentation (SSF) and concurrent source of cellulose for Cellulose nanocrystals (CNCs) preparation, using Serratia marcescens NITDPER1.
2022/8/13/ · Even, industrial organic sludges have potential for enhancing co-degradation of MSW and such wastes. Paper mill sludge (PMS) could increase degradation rates and bioenergy production through anaerobic co-disposal in landfill bioreactors (Srivastava and Chakma 2021b). However, maximum bioenergy generation and co-degradation relies on co
2021/8/11/ · Pulp and paper mill sludge (PPMS) represents a large part of the industrial waste and contains a high portion of the organic matter (Elliott and Mahmood, 2012a).Sludge waste is produced from both virgin and recycled paper production processes (Simão et al. 2018).However, this substrate is usually undesirable and needs to be treated or disposed of
2014/1/1/ · In this study, the start-up performance of treating recycled paper mill wastewater using a modified anaerobic inclining-baffled bioreactor (MAIB-R) has been studied.
2015/4/28/ · RECOMMENDED TREATMENT PROCESS OF PULP AND PAPER MILL EFFLUENTS. The treatment of effluents from pulp and paper mills has become an essential
2024/4/26/ · A pioneering solution has been developed to convert cellulose fibre-rich waste from pulp and paper mill operations into ethanol using a specialised fermentation process. Ethanol is a versatile starting material that finds diverse application in the production of industrial chemicals, bio-based plastics and sustainable aviation fuel.
Zwain and Dahlan Biological Treatment of Recycled Paper Mill Wastewater Using Modified Anaerobic Inclining-Baffled (MAIB) Bioreactor . 75 . the anaerobic reactor is accounted for by the methane
2022/11/9/ · The various other critical issues related to bioreactors remain unanswered, which we are highlighting in subsequent sections. For example; investigated the effect of anaerobic co-landfilling in simulated BLs on leachate strength obtained from a mixture of paper mill-based ETPS (effluent treatment plant sludge) and MSW. The results indicated
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
2021/4/29/ · A wide variety of biomass is available all around the world. Most of the biomass exists as a by-product from manufacturing industries. Pulp and paper mills contribute to a higher amount of these biomasses mostly discarded in the landfills creating an environmental burden. Biomasses from other sources have been used to produce different …
