the emerging contaminants are commonly derived from municipal, agricultural, and industrialwastewater sources and pathways. these compounds are polar and poorly biodegradable. the dynamicremoval of atenolol from aqueous solutions by activated carbon in fixed bed column systems was investigated. as far as we know, this is the first study reporting the decontamination by adsorption in fixed bed o...

the contamination of water by toxic heavy metals is a world-wide environmental problem. discharges containing cadmium, in particular, are strictly controlled due to the highly toxic nature of this element and its tendency to accumulate in the tissues of living organisms. low concentration (below 5 mg`/l) of cadmium is difficult to treat economically using chemical precipitation methodologies. i...

A sampling protocol was developed to examine particles released from granular activated carbon filter beds. A gauze filter/Swinnex procedure was used to collect carbon fines from 201 granular activated carbon-treated drinking water samples over 12 months. Application of a homogenization procedure (developed previously) indicated that 41.4% of the water samples had heterotrophic plate count bact...
