Activated carbon

Endocrine disrupting chemicals and pharmaceuticals represent two classes of emerging contaminants that are ubiquitously present in municipal wastewater effluents. Some of these contaminants have been shown to impact aquatic organisms at trace concentrations (i.e., ng/L). Moreover, the public has exp

The objectives of this research were to evaluate two different processes using for wastewater reclamation in a hightech industrial park area in Taiwan. The major units of the first AC–RO–IE system included sand filter, an activated carbon (AC) bed, microfiltration module, a reverse osmosis (RO) memb

A reuse system for carwash water with a cellulose acetate (CA), hollow-fiber-type ultrafiltration membrane with the aid of flocculation and activated carbon treatments was proposed. The multi-blended flocculating agent containing bentonite, Al2(SO4)3, sodium alginic acid and a cationic polyacrylamid

The investigation was undertaken to evaluate the effectiveness of using activated carbon (AC) in conjunction with ultrafiltration (UF) in the removal of methylene blue (MB) from aqueous solutions. The combination of activated carbon with UF in this work was to exploit the high adsorption capabilitie

Studies were carried out on the treatment of water for potable purposes using ceramic and capillary membranes. The studies involved the processes of unit microfiltration and ultrafiltration as well as hybrid processes. In the hybrid processes, adsorption on activated carbon and membrane separation w

Fine particles of photoactive anatase-type TiO2 were loaded on activated carbon and carbon spheres through the hydrolysis of titanium oxysulfate under autogenous hydrothermal conditions. Their photoactivity and adsorptivity were evaluated separately by the measurements of relative concentration of m

Environmental transformations caused by the economic human activity generate rapid changes in surface water quality. The application of activated carbon in conjunction with microfiltration/ultrafiltration processes is an emergency technology for the removal of organic compounds from water for consum
