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
2004/2/1/ · Moreover earlier studies of invessel composting of paper mill sludge required long time for the composting process and varied between 121 days to 28 days (Jackson and Line, 1997;Das et al., 2001).
MBR is used in the paper industry as end-of-pipe technology as well as process integrated measure for the reduction of the concentration of detrimental substances in the water circuit. Especially in terms of effluent quality and economical aspects a MBR is a sustainable technology for the industrial wastewater treatment. 3FM technology.
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
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
2013/7/23/ · Abstract. Economically viable and environmentally acceptable to recycle organic wastes are needed by the pulp and paper industry. We assessed the potential for composting the Virginia Fibre Corporation's (VFC) combined primary and secondary dewatered paper mill sludge (PMS) and evaluated the suitability of the finished product as
2023/7/28/ · Paper mill sludge (PMS), a waste product generated in significant quantities by pulp and paper mills, is one potential organic amendment that should be explored. PMS is a mixture of organic matter, inorganic matter, and water. It is generated during paper production, with approximately 40–50 kg of dry sludge produced per ton of
This work aimed to reveal the differences of nitrogen (N) transformation between animal-derived and plant-derived biochar during paper mill sludge composting. Three treatments were established, including CK (no biochar), ABC (animal-derived biochar), and PBC (plant-derived biochar). Results showed t
2000/1/1/ · Paper mill sludge (PS) generation in Wisconsin increases approximately 5% per year, and 70% of all PS generated currently (740,000 dry tons) is land filled (Wisconsin Paper Council, 1998; pers
Pulp and paper mill sludges are produced from primary and secondary treatment of wastes derived from virgin wood fiber sources, recycled paper products, and non-wood fibers. Sludges and sludge composts may be utilized in agriculture to increase soil organic matter, improve soil physical properties, provide nutrients, and increase soil pH. Positive effects of
Pulp and paper mill sludge (PPMS) is the main organic residual material generated from the wastewater treatment of pulp and paper industry. The properties of PPMS depend on the type of raw material, paper and pulp making process and wastewater treatment (Pervaiz & Sain 2015). In Vietnam, most of PPMS generated from the wastewater
Agronomy 2022, 12, 13 2 of 19 from the paper, food, wood and agricultural industries is currently unlimited [9,10]. Con‐ verting waste rich in organic matter and elements into composts is the
The metal zinc has the highest concentration in the sludge results at 68.90 ppm compared to the sludge standard at 2800 ppm. Figure 8 is a graph of the sludge results against the Department of
1999/12/1/ · Abstract. Wastewater treatment sludge and power boiler fly ash were combined and composted in mixed and static windrows 50 m long, 4 m high and 6 m wide. Moisture content was maintained above 50%. The final compost had a pH of 8.5, contained high concentrations of specific nutrients, and an average C:N ratio of 43:1.
