Review on recent progress in chitosan-based hydrogels for wastewater treatment application, Parisa Mohammadzadeh Pakdel & Seyed Jamaleddin Peighambardoust, Carbohydrate Polymers , Vol.201. Recently, chitosan has been used as a raw material for synthesis of hydrogels in a wide range of potential and practical applications like wastewater treatment, drug delivery, and tissue engineering. This review represents an overview of the application of chitosan-based hydrogels for wastewater treatment. Utilisation of natural cellulose fibres in wastewater treatment, Nur Syazwani Abd Rahman et al, Cellulose , Vol.25 (9). This review has explored the role of natural fibres as adsorbents for wastewater treatment while at the same time, for the removal of adsorbates such as oil, dyes, heavy metals, ionic compounds, and others as reported in the literature. Also investigated in this study, were the different modification types used to enhance the fibres and the mechanism of contaminant removal by the absorbents. Lastly, the physical forms of adsorbates and common types of effluents treated using natural fibres were examined and discussed. Effect of thermal sludge processing on selected components of air quality in the vicinity of a wastewater treatment plant, Robert Cichowicz et al, Chemical Papers , online. Wastewater treatment plants (WWTPs) generate considerable amounts of sewage sludge. The thermal sludge treatment system (TSTS) is therefore one of the most important technological units of a WWTP. However, due to technological processes involved in thermal sludge treatment, specific chemical, physical and biological conditions may arise that can affect air quality both within the WWTP area and in its vicinity. This study uses data from experimental measurements taken in and around a WWTP to assess the impact of thermal sludge treatment on air quality. Constructed Wetland Technology for Pulp and Paper Mill Wastewater Treatment, Satish Kumar & Ashutosh Kumar Choudhary, book chapter in Constructed Wetlands for Industrial Wastewater Treatment , Wiley. This chapter describes the characteristics of pulp and paper mill wastewater and the suitability of constructed wetlands (CWs) for wastewater treatment from such facilities. Paper sludge functionalization for achieving fiber-reinforced and low thermal conductivity calcium silicate insulating materials, Mingxu Chen et al, Journal of Thermal Analysis and Calorimetry , online. Paper sludge generated from the paper industry is classified as solid waste, comprising primarily wood fibre and calcium carbonate with low thermal conductivity. This paper is concentrated on the comparison of wood fibre and paper sludge from the structural strength and insulation property of calcium silicate insulating materials (CSIM). It can be concluded that the utilization of paper sludge presents a great potential to develop fibre-reinforced and low thermal conductivity CSIM and benefits to the development of waste management in producing sustainable CSIM. Fabrication of polypyrrole composite on perlite zeolite surface and its application for removal of copper from wood and paper factories wastewater, Ali Naghizadeh et al, Korean Journal of Chemical Engineering , Vol.35 (3). The large volumes of water used in wood and paper industries produce substantial amounts of wastewater. We studied copper removal from the effluents of a wood and paper factory by using a polypyrrole composite consisting of natural Zeolite coated on Perlite (PPy/Perlite). Evaluation of experimental information for studying the kinetics of copper adsorption by PPy/Perlite revealed that copper adsorption followed the pseudo-second-order kinetic model.
