Synthesizing polyethersulphone membranes with hybrid iron/nickel nanoparticles for dyes removal: An efficient biogenesis approach

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Industrial wastewater contamination by azo dyes poses a significant environmental challenge. This study reports the green synthesis of bimetallic iron/nickel (Fe/Ni) nanoparticles using moringa leaf extract, which acted as both a reducing and capping agent, and their incorporation into polyethersulphone (PES) membranes to produce eco‐friendly ...

Microplastics and nanoplastics in water: Improving removal in wastewater treatment plants with alternative coagulants

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
The contaminant removal performance of a conventional coagulant, alum, and alternative coagulants, aluminium chlorohydrate (ACH) and ACH + pDADMC, are compared in challenging wastewater treatment conditions (pH >7.8). The interactions of each coagulant with a negatively charged surface are depicted based on quartz crystal microbalance with dissipation ...

Economic and environmental implications of the development of UASB reactors in Mexico for sustainable industrial wastewater treatment

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The objective of this work is to demonstrate that the inclusion of an up‐flow anaerobic sludge bed (UASB reactor) within an industrial wastewater treatment plant reduces the plant's investment and operating costs compared to a system based solely on conventional complete‐mix activated sludge (CMAS), operating under the same design principles ...
