TL;DR: Of all the low cost adsorbents used in the study, saw dust is found to possess greater adsorption efficiency for all metals, than rice husk under identical experimental conditions.
Abstract: In this paper, a comparative study of removal efficiency of heavy metals [copper Cu(II), Manganese - Mn(II), Iron - Fe(II), Nickel - Ni(II), Lead - Pb(II) and Zinc -[Zn(II)] from aqueous solution by adsorption on non-conventional materials and on chemically activated non-conventional materials, is presented. It is found that the adsorption potential varies as a function of contact time, concentration, particle size, pH and flow rate. Of all the low cost adsorbents used in the study, saw dust is found to possess greater adsorption efficiency for all metals, than rice husk under identical experimental conditions. Chemically activated saw dust could remove 98.28% of Cu(II); 100% of Mn(II); 96.72% of Fe(II); 96.72% of Cd(II); 75% of Cr(VI); 80% of Ni(II); 95% of Pb(II) and 93% of Zn(II), from the corresponding metal solution taken one at a time.

TL;DR: A laboratory-scale study was conducted to evaluate the efficiency of a fluidized bed reactor operated under anaerobic condition with bioaugmentation to treat the cephalexin containing pharmaceutical factory effluent to show that bioaumentation could be used to promote biological treatment to applications where conventional operation might be difficult or unfavourable.

TL;DR: The viability of treating high‐concentration antibiotic wastewater by an anaerobic membrane bioreactor with enhanced biodegradation using the bioaugmentation technique was studied using submerged flat sheet membrane.
Abstract: The viability of treating high‐concentration antibiotic wastewater by an anaerobic membrane bioreactor was studied using submerged flat sheet membrane. The objective of the study was to determine the effect of organic loading rate and hydraulic retention time on the removal of cephalosporin derivative, viz. cephalexin, and the intermediates 7‐amino‐3‐deacetoxycephalosporanic acid (7‐ADCA) and acyl group (phenyl acetic acid) in an anaerobic membrane bioreactor with enhanced biodegradation using the bioaugmentation technique. The pharmaceutical industry is looking for alternatives to either direct disposal of 7‐amino‐3‐deacetoxycephalosporanic acid and phenyl acetic acid, or further degradation and disposal, which will essentially require additional costs and maintenance. The present regulatory standard, implemented at a global level, does not allow for such disposal alternatives and hence the present study was aimed at the complete removal of the intermediates 7‐ADCA and phenyl acetic acid prior to discharge.
