water purification [′wȯd·ər ‚pyu̇r·ə·fə′kā·shən] (civil engineering) Any of several processes in which undesirable impurities in water are removed or neutralized; for example, chlorination, filtration, primary treatment, ion exchange, and distillation. ...
A water filtration article has a filtration layer of thickness no larger than 10 microns including porous polytetrafluoroethylene coated with a hydrophilic coating comprising uncrosslinked ethylene-vinyl alcohol copolymer. Methods include water filtration using and manufacture of such a water filtration ...
Filtration –filtration is achieved by passing wastewater through screens which contain openings to let the water pass through (leaving behind any large solids present in the water). Disinfection –microorganisms are killed using a range of methods. For example, the addition of chemicals such as chl...
crossflow filtration A water filtration process in which a semipermeable membrane is used to separate waterborne contaminants from the water. The bulk solution flows over and parallel to the filter surface, and under pressure, a portion of the water is forced through the membrane filter. ...
The aim of this work was to synthesize a green nanoparticle SnCuO@FeO nanocomposite core–shell to break oily water emulsions during petroleum-enhancing production processes as an alternative to chemical and physical processes. In this study, eight bacte
Water is essential for human life. Why not take back control of your taps? A Water Filtration System Can Work Wonders Our water is now safer than it was at any point in history. But as our infrastructure ages, weather patterns change, and we learn more about what lives in our water sup...
of the earth to the groundwater table is called the aeration zone, within which water seeps from the surface. In the aeration zone, during periods of groundwater recharge, certain rock interlayers with a lower filtration capacity temporarily accumulate subterranean water known as leakage water. ...
, after 20 min filtration reaction, the degradation products were reduced drastically. P8 disappeared, and P11 (not harmful product) dominated the final degradation products. As such, it can be concluded that the Co-TiOxmembrane-based angstrom-confined catalysis not only efficiently removed water ...
Filtration and concentration of EPC-secretome EPC-secretome obtained by LSP (HD-CM and SP-CM) or HSP (CM), and fresh protein-free EBM (control) were filtered through a 0.22-μm vacuum filter to remove cells and debris. Centricon Plus-70 filters (3 kDa Ultracel-PL membrane—Millipore) we...
1. A smoking article comprising a rod of smoking material, a filter and wrapping paper means extending about said filter, adhesive anchoring said wrapper means being water susceptible adhesive and said filter comprising water-disintegratable paper filtration material, said paper filtration material being...
