Technol., 98 (2007) Influence of pretreatment techniques on anaerobic digestion of pulp and paper mill sludge: a review. Bioresour. Technol. (2017), pp. 1206-1219,
the inoculated compost at the certain stages of the composting process. It was recommended to use thermophilic bacteria as a start inoculum to improve the PPMS composting process. Keywords: thermophilic bacteria, pulp and paper mill sludge, DGGE, API ZYM 1. INTRODUCTION Pulp and paper mill sludge (PPMS) is the main organic residual
1. Introduction. Paper mill sludge (PS) is a significant byproduct generated in the pulp and paper industry. With the increasing demand for paper and board products, the global annual production of PS exceeds 400 million tons (Feng et al., 2022).PS primarily consists of cellulose fibers, lignin, and inorganic fillers like CaCO 3 and Kaolin, thus it has a great potential for
2021/6/1/ · The research aims to inspect the potentiality of effluent treatment plant sludge (ETPS) procured from paper mill for co-disposal with MSW under anaerobic landfilling environment. Both ETPS and MSW were disposed in three different ratios (ETPS: MSW); 25:75, 50:50 and 75:25 while keeping one reactor as control, consisting only MSW.
2019/12/1/ · 1. Introduction. Citronella bagasse and paper mill sludge are the by-products of agro based industry. Cymbopogon winterianus Jowitt which is commonly known as java citronella is an aromatic, perennial, evergreen, clump-forming grass belonging to family Poaceae and cultivated commercially in several countries of the world for production of
2013/7/23/ · We assessed the potential for composting the Virginia Fibre Corporation's (VFC) combined primary and secondary dewatered paper mill sludge (PMS) and evaluated
2023/7/25/ · The composting process can recycle sludge effectively, but it still has some drawbacks. Many studies suggest that biochar addition in sludge composting can effectively improve the composting environment and overcome these drawbacks, due to its high carbon content, developed pore structure, rich surface functional groups, and adjustable
2012/12/15/ · The aim of this paper was to study the influence of four process variables (turning frequency, gas-phase oxygen level, type of bulking agent and sludge/bulking agent mixing ratio) on the performance of the sewage sludge composting process using a rotary drum pilot scale reactor, in order to optimize the thermophilic stage and reduce the
2016/6/5/ · Paper mill sludge is one of the largest underutilized organic by -products in Wisconsin. Paper mill sludge (PS) generation in Wisconsin increases approximately 5% per year, a nd 70% of all PS generated currently (740,000 dry tons) is land filled (Wisconsin Paper Council, 1998; pers. comm.). As landfill options decline for both economic and
1997/1/1/ · The feasibility of aerobic vessel composting and anaerobic digestion for the treatment of pulp and paper mill sludges were studied. The composting studies made use of primary and secondary sludge from a de-inking and paper mill. In six parallelly aerated 500 l vessels with various carbon : nitrogen (C:N) -ratios, the most optimal performance
2017/12/20/ · Article Effect of composting of paper mill sludge for land spreading was published on December 20, 2017 in the journal Nordic Pulp & Paper Research Journal
All the prepared compost samples sub-samples and sample of paper mill sludge before composting were taken, air dried and sieved through 2 mm sieved and extracts were processed for physico-chemical
Co-composting dewatered paper mill sludge (PMS) and hardwood sawdust, two readily available materials in Canada, was investigated using uncontrolled and controlled In tank processes. The composted materials were characterized for total C and N, water-soluble, acid-hydrolyzable, and non-hydrolyzable N, extractable lipids, and by Fourier
2016/3/1/ · Pulp and paper mill sludge (PPMS) is an organic residual generated from the wastewater treatments. PPMS management involves economic, environmental and social …
