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.
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…
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…
The analysis, published in Discover Chemical Engineering, compares ozonation and catalytic ozonation with the Fenton process as a representative advanced oxidation process, and uses response surface methodology to distil generalized optimization trends from the published literature. By ranking the sensitivity…
A laboratory study finds that ball-milled wood biochar reduces silver ions to silver nanoparticles only under weakly alkaline conditions, driven by superoxide radicals. Nano-biochar turns toxic silver ions into nanoparticles only when pH rises Silver ions are among the more…
Under optimised conditions, the equilibrium adsorption data were best described by the Langmuir isotherm model. The maximum adsorption capacities reached 356 milligrams per gram for PFOA and 225 milligrams per gram for PFUnDA, indicating that the material took up both compounds efficiently,…
A magnetically recoverable fungal biomass composite modified with copper ferrite nanoparticles and the MOF ZIF-67 removed up to 99.17 percent of cadmium from synthetic solutions and 70.2 to 82.6 percent from real industrial wastewaters.
A batch adsorption study reports that a locally engineered powdered activated carbon removed 69.4% of COD and 73.7% of BOD5 from Kumasi Abattoir effluent at 25 g/L.
Separation processes and materials: membranes, adsorbents, filtration and distillation, desalination and the technology of treating water and wastewater.
