Microplastics and heavy metals are increasingly found together in agricultural soils, where they threaten crop productivity and raise concerns for human health. The researchers set out to test whether biochar modified with calcium oxide nanoparticles, abbreviated NBC, could blunt the…
A new review maps how solar-powered membrane distillation can move from promising laboratory demonstrations to credible field-ready desalination through integrated system design.
Researchers green-synthesized silver-doped nanoparticles from Moringa oleifera seeds, optimized their removal of methylene blue dye, and tested them on real textile effluent.
A greenhouse pot study found that fresh chitosan-functionalized biochar cut soil-available arsenic by 21.1 percent and root arsenic by 48.1 percent in rice, while six months of natural aging shifted the material toward iron-mediated sequestration. Chitosan-Modified Biochar Cuts Arsenic in Rice, Aging…
A new review argues that amine-based biphasic absorbents, which split into CO2-rich and CO2-lean phases after capturing carbon dioxide, can cut regeneration energy by 30 to 85 percent compared with conventional MEA solvents, though laboratory results remain largely unvalidated at pilot scale.
Powdered activated carbon is one of the most effective catalysts ever tested for destroying stubborn organic pollutants with ozone, but a cloud of fine carbon particles swirling through a wastewater reactor is an engineer’s nightmare. The powder is hard to…
Waters supersaturated with sparingly soluble salts are encountered in RO/NF (reverse osmosis/nanofiltration) membrane-based water treatment processes, cooling water discharge, and produced water from oil and natural gas operations. Thermodynamically driven de-supersaturation results in salt precipitation causing strongly adherent…
A laboratory column study found that amending saturated sand with 10 percent malt spent rootlets biochar raised E. coli removal from 17.8 to 94.1 percent.
Newswise — Researchers from Minzu University of China, et al. have conducted a study entitled “Quantitative temporal-based contribution of key foulants to fouling proceeding in direct membrane... Quantitative Temporal-Based Contribution of Key Foulants to Fouling Proceeding in Direct Membrane Filtration for…
Researchers built a single-piece cellulose membrane with one hydrophobic and one superhydrophilic face that separates oil from water under gravity, retaining up to 95 percent of oil at fluxes above 3300 liters per square meter per hour. Article Title: Design of a…
Turning chemistry into processes: process design and scale-up, separations and membranes, reactors and process intensification, and cleaner chemical plants.
