Book excerpt: Pulp and Paper Industry: Emerging Waste Water Treatment Technologies is the first book which comprehensively reviews this topic. Over the past decade, pulp and paper companies have continued to focus on minimizing fresh water use and effluent discharges as part of their move towards sustainable operating practices. Three stages—basic conservation, water reuse and water recycling—provide a systematic approach to water resource management. Implementing these stages requires increased financial investment and better utilization of water resources. The ultimate goal for pulp and paper companies is to have effluent-free factories with no negative environmental impact. The traditional water treatment technologies that are used in paper mills are not able to remove recalcitrant contaminants. Therefore, advanced water treatment technologies are being included in industrial wastewater treatment chains aiming to either improve water biodegradability or its final quality. This book discusses various measures being adopted by the pulp and paper industry to reduce water consumption and treatment techniques to treat wastewater to recover it for reuse. The book also examines the emerging technologies for treatment of effluents and presents examples of full-scale installations. - Provides thorough and in-depth coverage of advanced treatment technologies which will benefit the industry personnel, pulp manufacturers, researchers and advanced students - Presents new treatment strategies to improve water reuse and fulfill the legislation in force regarding wastewater discharge - Presents viable solutions for pulp and paper manufacturers in terms of wastewater treatment - Presents examples of full-scale installations to help motivate mill personnel to incorporate new technologies

This book was released on 1976 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pulp and paper industry produces large volumes of effluent containing, among other things, dark brown lignin and lignin degradation products. The exact nature of the chromophoric (colour causing) groups in the wastes and the effects of these colour bodies on the aquatic environment are not known. However, developmental work on several processes for colour reduction has reached full scale application and colour removal is now required in many local areas for various reasons. Colour reduction can be achieved by either technical changes within the mill or by effluent treatment systems. In-plant modification can range from simple, inexpensive measures such as pulp washing and better "housekeeping" practices, to complex technological changes such as implementation of oxygen bleaching. While in-plant changes should be considered and implemented as a first preference, external treatment may often still be required. There are a large number of external treatment methods which are known to be technically feasible for colour removal from pulp and paper mill effluents.

This book was released on 2012 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: The removal of colour, organics and phosphorus from pulp and paper mill effluent and the development of colour of the wastewater were investigated. These contaminants are considered to be the most important due to their resistance over common treatment applied by the mill.Two approaches, adsorption and coagulation, were chosen for investigation of the removal of colour, organics and phosphorus from aqueous discharges of a bisulphite pulp and paper mill. Additionally, the colour generation induced by UV irradiation of the treated effluents was investigated. This study was carried out to explore the possibility of UV-induced colour development of the effluent over the long term and to characterize the colour producing species from the wastewater.Cheap and highly abundant brown coal (or lignite) was utilized as adsorbent for colour, phosphorus, and organics from the industrial effluent. Knowledge on the mechanism of brown coal adsorption, selectivity, the effect of pre-treatment and physical properties of brown coal is crucial for the future application of brown coal in the water industry. The mechanism of brown coal adsorption was investigated using various brown coal samples differing in physical and chemical composition and two model dye solutions, cationic (safranin) and anionic (alizarin red) dyes. The capacities of some brown coals (Loy Yang high Na and Yallourn) were higher than commercial coal-based activated carbon. However, the adsorption capacities of all brown coal samples for an anionic dye were very low, less than 3% of that for activated carbon. This result reveals the potential of brown coal to remove positively charged contaminants from aqueous solutions and suggests cation-exchange as the major mechanism involved. Effects of brown coal pre-treatment, drying and washing, were investigated. The equilibrium adsorption data were analysed using the two most popular adsorption isotherms, Langmuir and Freundlich. The Langmuir isotherm fitted most adsorption data of brown coal better than the Freundlich isotherm, supporting the concept of monolayer adsorption and the role of chemical adsorption in the mechanism. When applied to actual wastewater from a magnesium bisulphite pulp and paper mill, brown coal exhibited multi-component adsorption of colour, organics and phosphorus from the solution. Brown coal showed an ability to remove phosphorus from the wastewater, which could not be achieved with activated carbon; yet brown coal had significantly lower adsorption capacities for colour and organics than did activated carbon. This can be explained by the nature of organics and colour that carried negative charge in the wastewater as indicated by the zeta potential analysis. Another powerful technique for organic removal, coagulation, was then chosen to significantly reduce colour and organics content of the effluent.Coagulation using trivalent salts was selected to efficiently remove colour, organics and total phosphorus in the treated and untreated wastewater solution. Selectivity of salt-induced coagulation was achieved and showed the following trend of removal efficiency: colour ~ total phosphorus > TOC. The removal of colour and total phosphorus from concentrated pulp mill effluents were above 90%. The coagulation method was proven to be superior for the remediation of both treated and untreated effluent from pulp and paper industry. However, a small amount of colour and organics still persisted in the wastewater which may lead to colour development after treatment at the collecting discharge point.The Photometric Dispersion Analyzer (PDA) and Focused Beam Reflectance Measurement (FBRM) techniques were utilised to study the coagulation kinetics of the wastewater upon addition of salt. The involvement of fast aggregation and adsorption in the coagulation mechanism were revealed. The high critical coagulation concentration (CCC) and the significant role of trivalent salts in the coagulation process indicated the involvement of complexation reactions prior to coagulation. In coagulation, pH was also found to be a dominant factor affecting efficiency.The UV-induced colour generation of the effluent from pulp and paper industry was studied using UV-irradiation at 302 nm and 254 nm. Lignin derived compounds were suspected to be responsible for colour growth of pulp and paper wastewater. Three model compounds, lignosulfonic acid, humic acid and vanillin, were selected and studied as comparison. The yellowing rate of the wastewater solution was found to be similar to that of the model lignosulfonic acid solution supporting the occurrence of lignin compounds in the wastewater. The yellowing rate of humic acid was lower than the wastewater solution, but the yellowing rate for vanillin was significantly higher than that of the wastewater solution. The irradiation products were analysed using High Performance Liquid Chromatography (HPLC), UV spectroscopy, Electrospray Mass Spectrometry (ES-MS), Proton Nuclear Magnetic Resonance (1H-NMR) and Fourier Transform Infrared Spectroscopy (FTIR). The mechanism of wastewater yellowing upon irradiation was suspected to mimic the mechanism of photo-yellowing of paper. The result also suggested that UV-induced chemical reactions may be important in the aqueous discharge of pulp and paper mill effluent that could potentially enhance its colour.
