    Improvement of Commercial Active Carbon for Use in an Adsorption Cooling System by B. Buczek, L. Czepirski, E. Komorowska-Czepirska

    Published 2003-02-01
    “…The porous structures of two series of active carbons modified by the successive removal of the external layers from the particle surface, one by abrasion in a spouted bed and the other by subsequent demineralization of the abraded particles, were evaluated on the basis of nitrogen and methanol adsorption data. The porous structure parameters for these two sorbate series agreed reasonably well and allowed the D–R approach to be usefully applied for the characterization of these systems. …”

    Application and Development of Bio-sand Filtration Technology for Processing Drinking Water in Rural Areas by ZHANG Kexuan, LI Jie, XIAO Juqiang

    Published 2022-01-01
    “…It has been a focus for researchers to study how to ensure the safety of drinking water in rural areas.Bio-sand filtration (BSF) technology has advantages including convenient construction,low water production costs,low energy consumption,and stable and reliable operation,and thus it is more suitable for promotion in rural areas than that in cities.Considering the water shortage and drinking water safety issues,this paper introduces the removal effects of BSF on pollutants such as turbidity,organic pollution,nitrogen and phosphorus,bacteria,and metals,and the advantages and disadvantages of BSF are compared.Moreover,the future application prospects of BSF technology are discussed.…”
