A multipurpose organometallic pyridyl Schiff base-modified poly(divinylbenzene) matrix for the catalytic removal of nitrophenols and polycyclic pollutants J. Water Process. Eng. (IF 6.3) Pub Date : 2024-09-10 Junhu Zhao, Ming Li, Jiajia Jiang, Wusheng Rao, Pier-Luc Tremblay, Tian Zhang
Widespread organic pollutants in wastewater include toxic nitrophenols and polycyclic molecules. Here, we aim to develop a single multipurpose catalyst capable of degrading these structurally dissimilar contaminants by preparing a pyridyl Schiff base-functionalized poly(divinylbenzene) porous organic polymer displaying Ag complexes (PDVB-PA@Ag). PDVB-PA@Ag hydrogenated 4-nitrophenol (4-NP) efficiently

Synergistic electro-thermal enhancement of nitrogen removal in an iron-based Anammox system at low temperatures J. Water Process. Eng. (IF 6.3) Pub Date : 2024-09-10 Fei Xie, Xiaogang Li, Philip Antwi, Li Ji, Muhammad Ehsan Danish, Bowei Zhao
In this study, a novel AC-stimulation technology was explored by synergistic electro-thermal enhancement for nitrogen removal in a Fe-based Anammox at low temperatures. Highest total nitrogen (TN) removal efficiency achieved by the AC-stimulated Anammox system was 73.59 % at 0.45 mA/cm AC densities, compared to 45.72 % TN removal efficiency realized in the control (non-AC-stimulated) Anammox system

Advancing sustainability: The role of epiplastic microalgae and their enzymatic pathways in freshwater plastic biodegradation J. Water Process. Eng. (IF 6.3) Pub Date : 2024-09-10 Antony Prakash Rejoy P, Sagaya John Paul Joseph, Nagaraj Subramani
Plastic pollution in freshwater ecosystems is a critical issue due to low recycling rates and improper disposal. While plastics are valued for their durability, they significantly contaminate water bodies, threatening aquatic biodiversity and ecosystem health. Microplastics account for about 3.5 % of total plastics produced, with synthetic textile industries releasing over 1100 tons of fibers annually

Microplastics as vectors for antibiotic resistance: Role of pathogens, heavy metals, and pharmaceuticals and personal care products J. Water Process. Eng. (IF 6.3) Pub Date : 2024-09-10 Linjun Wu, Jiao Dong, Zhiqiang Shen, Yuexi Zhou
Microplastics have become ubiquitous in the environment due to the uncontrolled usage of plastic products. During their migration, microorganisms colonize their surface, forming what is known as plastisphere. The presence of human pathogenic bacteria on the plastisphere presents new opportunities for the spread of diseases during its extensive migration. Additionally, the plastisphere has been found
