网页2022年12月15日 · A new technology is described that enables us to completely exclude liquid discharges during production of drinking water from surface sources. The proposed described technological scheme separates the natural water into a stream of purified drinking water and dewatered sludge. The sludge moisture has a value of 80 percent.
网页A novel free-standing and flexible electrospun carbon–silica composite nanofibrous membrane is newly introduced. The characterization results suggest that the electrospun composite nanofibers are constructed by carbon chains interpenetrated through a linear network of 3-dimensional SiO2. Thermogravimetric analysis indicates that the presence of
网页2018年8月7日 · Membrane-sample Compatibility It’s easy to overlook membrane compatibility when picking out your filter or device for your sample filtration.
