Pulp and paper mill Industries produce large amounts of waste which is disposed in landfills. One of the greatest sources of landfill waste in the pulp and paper mills is green liquor dregs whose amount is usually 5 - 20 kg/ADt pulp. Due to the high pH level green liquor dregs, it …

waste streams from pulp and paper mills include wastewater treatment sludges, lime mud, lime slaker grits1, green liquor dregs2, boiler and furnace ash, scrubber sludges and wood processing residuals. In terms of volume, most solids or liquids are those from the treatment of effluents, although waste from wood is also produced in large quantities

Major identified sources of waste in pulp and paper industry are from: a) separator b) washing tank c) bleaching stages d) paper machine. The bleached pulp is then sent for the paper mill where the final product paper is produced. A small volume of waste water is also produced when the bark is removed from the raw water and later is reduced to chips by wet process.

The pulp mill would be located in the department of Durazno on the southern side of Rio Negro, 4-5 km downstream from the city of Paso de los Toros and Centenario village World-class single line pulp mill with proven environmental performance and Best Available Techniques (BAT) would have a production capacity of approx. 2 million tonnes of ...

average mill waste generation of 100 kg per air dried metric ton (ADMT) pulp, the waste generated at kraft pulp mills amounts to be 14 million metric tons globally. The majority of the waste consists of sludge from wastewater treatment, ash from biomass combustion, green liquor dregs, lime mud, and slaker grits from causticizing.

Diagram of a pulp mill treatment plant with activated sludge as biological treatment. The removal efficiencies reached vary according to the wastewater residence time and the operating conditions. Normal efficiencies figures are between 85 and 98% BOD 5 removal and 60–85% for COD removal. For AOX, the reduction is about 40–65%, 40–85% for ...

Wood received at a pulp mill may be in several different forms, depending on the pulping process and the origin of the raw material. It maybe received as bolts (short logs) of roundwood with the bark still attached, as chips about the size of a half-dollar that may have been produced from sawmill or veneer mill waste or pre-chipped from ...

At our Slave Lake Pulp mill in Alberta, we make energy from the by-products of our pulping process, namely the pulp mill effluent (wastewater) that many people think of as a waste product. After we have refined wood chips and recovered the pulp…

The pulp and paper mill wastewater is mostly deficient in dissolved oxygen and associated with extreme values of BOD and COD. The high BOD is caused due to suspended low molecular weight solids. Chakravarty et al (1995) reported that in most cases, the BOD of pulp and paper mill effluent varied between 1200 to 1800 mg/l.

to its final product sometimes produces wastes that are difficult if not impossible to re-pulp with conventional technology. For example, many paper products are laminated with plastic. Many mills either process laminated waste paper into pellets for boiler fuel or pay to have the wastes land filled.
