Determining the degree of reducing power multi-walled carbon nanotubes (MWCNTs) and granular activated (GAC) enables their effective application in various fields. In this study, we estimate (CNTs) GAC by measuring reduction compounds with different potentials. MWCNTs materials can reduce Cr(VI), Fe(III) PMo12O403−, where potentials range from +1.33 V to +0.65 V. However, no reduced forms PW12O...
BACKGROUND The primary role of granular activated carbon (GAC) in water treatment is to adsorb organic compounds that could potentially harm humans or impart tastes and odors. Several hundred water utilities in the United States and Europe use GAC for this purpose. While the GAC is in service, however, it can also accumulate metals, either by precipitation or by adsorption of metal-organic comp...
• Estimating the expansion of granular activated carbon (GAC) in water is complex. The incipient porosity GAC much higher compared to rigid particles. Combining fluidisation and characterisation experiments enables modelling. modelling complex but possible. Granular filtration an important unit operation drinking treatment. widely used for its adsorption capabilities as a barrier undesired orga...
Background : Nitrogen-containing ions such as nitrate and nitrite occur widely in a variety of water sources. This pollutant causes health problems such as the blue-baby syndrome, and possible formation of carcinogenic compounds in the digestive tract. Thus, removing them from water sources seems necessary. Biological denitrification is a method used in the treatment of nitrate contaminated wat...
