ClearWastewater Treatment in Central Asia: Treatment Alternatives for Safe Water Reuse
This review examines wastewater treatment challenges in Central Asia, where treated wastewater is increasingly reused due to water scarcity despite inadequate treatment infrastructure. Researchers found that current practices often fail to remove contaminants of emerging concern before effluent enters surface and groundwater used for drinking and irrigation. The study explores alternative treatment technologies, including biological systems, advanced oxidation processes, and managed aquifer recharge, aimed at improving water quality for safe reuse.
Cellulose-Based Sorbents: A Comprehensive Review of Current Advances in Water Remediation and Future Prospects
This review examines advances in cellulose-based sorbent materials for removing heavy metals and organic pollutants from wastewater. The study highlights that various modification methods such as carboxylation, amination, and oxidation can enhance cellulose's sorption capacity, making it a promising biodegradable alternative for sustainable water treatment technologies.
Integrated Recycling and The Impact of Plastic Waste from Industry and Agriculture on The Environment
This review examined the environmental impacts of plastic waste from industrial and agricultural sources and assessed integrated recycling strategies for reducing those impacts. The paper discussed how plastic waste prevention, collection, and recycling can minimize pollution and climate contributions from the growing global plastic waste stream.
New color changing sorption material for effective removal of heavy metals from wastewater
Researchers synthesized a novel zeolite-based sorbent modified with polyethylene polyamine, 1,2-pyridylazonaphthol, and ED-20 epoxy resin for removing heavy metal cations from wastewater, achieving a maximum sorption capacity of 220 mg/g. The material provides a visual color-change indicator of sorption efficiency, is unaffected by competing alkali and alkaline earth metal cations, and can be regenerated and reused across 10-12 desorption cycles using 0.20 M HCl.
ISOLATION OF MICROFIBERS IN THE PROCESSING OF POLYAMIDE FABRICS
This Russian study examined the release of synthetic microfibers during mechanical processing of polyamide fabrics — including cutting and sewing — finding that manufacturing operations are a significant but overlooked source of microplastic fiber pollution.
