Abstract
Microfiltration (MF) and ultrafiltration (UF) membrane filtration and separation of insoluble particles and dissolved solid in water, aerosolization, and subsequent sizing and counting of airborne particles were used to determine the number concentration of insoluble particles (#/ml) and mass concentration of dissolved solids (ppm) in water. By using a variety of solutions and their mixtures, we determined the penetration of insoluble particles and dissolved solids via the MF and UF membranes, as well as established a relationship between particle quantity in water and air. Both sub-500 nm insoluble particles and most dissolved solids passed through the MF membrane, while only dissolved solids passed through the UF membrane, enabling separation of waterborne insoluble particles and dissolved solids. Accordingly, we estimated the submicrometer particle number concentration and dissolved species mass concentrations via the proposed technique with 15% and 16% accuracy, respectively. Further, we examined the ...
