Thesis (Ph.D.)--University of Delaware, 2004.

This research focuses on Pb(II), Zn(II), Co(II), Cd(II), Ni(II), Cu(II) sorption kinetics and equilibrium by anaerobically digested sludge. The aim of this study is to understand the fate and transport mechanisms of heavy metals in wastewater treatment plant is important to the development of heavy metal control strategies, the operation and the design of sludge management systems.Subjects--Topical Terms:

520 $a This research focuses on Pb(II), Zn(II), Co(II), Cd(II), Ni(II), Cu(II) sorption kinetics and equilibrium by anaerobically digested sludge. The aim of this study is to understand the fate and transport mechanisms of heavy metals in wastewater treatment plant is important to the development of heavy metal control strategies, the operation and the design of sludge management systems.
520 $a Field studies were conducted at four participating wastewater treatment plants (Wilmington WWTP, DE, Baltimore - Back River WWTP, MD, Philadelphia - Northeast WWTP, PA, and Washington - Blue Plains WWTP, D.C.) in the Mid-Atlantic region. Wastewater samples and sludge particulates were characterized. For sludge particulates samples, the following chemical properties were determined: pH, major cations (K<super>+</super>, Na<super>+</super>, Ca<super>2+</super>, Mg<super>2+</super>, Fe<super>2+</super> and Fe<super>3+</super>), major anions (Cl<super>−</super>, SO<sub>4</sub><super>2−</super>, NO<sub> 3</sub><super>−</super> and S<super>2−</super>), and, DOM (dissolved organic mater), total metals. In addition the sludge physical properties such as the specific surface area, surface charges and zeta potential, were also being investigated.
520 $a For all of the metal anaerobically digested sludge systems studied using batch metal experiments, the developed uptake and release expression provided the best fitting kinetic model. In general the kinetic experimental result shows the order of Log Ks as follows: Pb(II) > Cu(II) > Cd(II) &cong; Ni(II) > Co(II) > Zn(II). Metal uptake by sludge particulate is a rapid process; generally uptake occurs rapidly, in a matter of minutes, upon contact between heavy metal and sludge particulates followed by a slowly progressing step.
520 $a In case of equilibrium aspect, the developed equilibrium expression also accommodated metal sludge relationship. Different affinity of metal uptake into sludge in equilibrium experiment in general order of Log Ks is as follows: Cd(II) &cong; Pb(II) > Cu(II) > Zn(II) > Ni(II) &cong; Co(II). Higher stability constant theoretically represents higher uptake capability.
