— This is also one of the significant uses of power boiler fly ash for treating the pulp and paper mill wastewater. In the case of using fly ash as an adsorbent, the metal salts get hydrolyzed in the presence of natural alkalinity to form metal hydroxides. The multivalent cations present in the fly ash can reduce the zeta potential value, while ...

 — The fly ash was derived from an electrostatic precipitator of a fluidized bed boiler in the co-combustion (55% bark and wood residues,45% peat) process at pulp and paper mill in Northern Finland. The accuracy of the leaching procedure was tested using a certified reference material SRM 1633b (Coal Fly Ash).

 — A Canadian study assessing the potential of ash residue as an amendment for road construction found considerable benefits in both laboratory and field tests when fly ash from a pulp and paper mill was added at a rate of 10% by weight (Zhou et al., 2000). With this addition rate in the lab tests, the unconfined compressive strength increased ...

modified pulp and paper mill fly ash can be environmentally and economically advantageous over commercial coal-based fly ash in various sustainable applications.

 — The inorganic solid waste generated in pulp and paper industries called pulp mill fly ash (PFA) is a potentially valuable resource as supplementary cementitious material.

 — Fly ash (FA) is the principal industrial waste byproduct from the burning of solid fuels. FA is a powdery solid that is constituted mostly of unburned carbon (UC), metal oxides (Si, Fe, Ca, and Al), and other inorganic substances. ... press mud, cow and farmyard manure, sewage and paper factory sludge, and crop residues (Sajwan et al., …

 — Fluoride removal from aqueous solution by adsorption using fly ash cenospheres (FAC)modified with paper mill lime mud (LM)as composite adsorbent had been investigated.

 — Supplies of commonly applied SCMs such as fly ash and blast furnace slag are becoming limited, and therefore the search for alternative SCMs is of high significance. The present research investigates the viability of four paper mill ashes collected at different stages from the same incineration process as SCMs at different cement substitution ...

 — The present study deals with the use of poly aluminium chloride (PAC) as a coagulant and bagasse fly ash (BFA), which is generated in sugar mills, as an adsorbent for the removal of chemical oxygen demand (COD) and colour of pulp and paper mill effluents. Under optimal conditions of pH 3 and initial PAC dosage of 3 g/l, about 80% COD …

Annually, due to the incineration of large amounts of biomass, a considerable amount of total ash (fly-ash and bottom ash) is generated from mill operation and disposed to …
