Removal of Pb(II) from aqueous solution by oxidized multiwalled carbon nanotubes.

Di Xu, +3 more
- 15 Jun 2008 - 
TL;DR: The results indicate that sorption of Pb(II) on oxidized MWCNTs is strongly dependent on pH values, and independent of ionic strength and the type of foreign ions.

Distribution of estrogens, 17β-estradiol and estrone, in Canadian municipal wastewater treatment plants

Mark R. Servos, +10 more
- 05 Jan 2005 - 
TL;DR: In this article, the distribution of female hormones, 17β-estradiol and estrone, was determined in effluents of 18 selected municipal treatment plants across Canada, and the removal efficiency compared to the operational characteristics of the plants.
Journal ArticleDOI

Mesophilic and thermophilic anaerobic digestion of primary and secondary sludge. Effect of pre-treatment at elevated temperature

Hariklia N. Gavala, +4 more
- 01 Nov 2003 - 
TL;DR: The results suggest that the selection of the pre-treatment duration as well as the temperature of the subsequent anaerobic step for sludge stabilization should depend on the ratio of primary to secondary sludge.
Journal ArticleDOI

Biological water denitrification—A review

Vít Matějů, +3 more
- 01 Mar 1992 - 
TL;DR: Different methods of biological denitrification of drinking water as well as the microbiology and stoichiometry of the process are reviewed in this paper, where the authors present a review of the literature.

Sphere Drag and Settling Velocity Revisited

Phillip P. Brown, +1 more
- 01 Mar 2003 - 
TL;DR: In this article, the Fair and Geyer equation was used to calculate the settling velocity of a small diameter cylindrical vessel in the presence of the wall effect, and two new correlations of the same forms were developed using the corrected data.
