The present paper reveals results of research for cost-effective removal of chemical oxygen demand (COD) contained in industrial paper mill effluent. Not only process efficiency but also wastewater treatment costs are discussed. Different pre-treatment processes are applied aiming to investigate the COD removal before discharge to the municipal sewage network. The objective of this paper… Continue reading Cost-effective removal of COD in the pre-treatment of wastewater from the paper industry
Different pre-treatment processes were applied to investigate the removal of chemical oxygen demand (COD) from paper mill effluent. The objective of this paper is to find the optimal operating conditions for coagulation process. The effect of key operational parameters, including the type of coagulant, initial pH, temperature, and coagulant dose, on the percent removal of… Continue reading Cost-effective removal of cod in the pre-treatment of wastewater from paper industry
Abstract: Odor emissions are one of the major environmental impact generated by wastewater treatment plants (WWTPs) perceived by exposed population. Consequently, the control of odor emissions is a relevant aspect that must be considered in the management of the WWTPs. Any efficient strategy for odor control was based on direct and/or indirect monitoring and characterization… Continue reading A novel tool for odor emission assessment in wastewater treatment plant
