Prior to nitrogen adsorption experiment to determine surface properties, ACC sample was degassed at 130°C under vacuum (up to 10 torr) for 12 h. The adsorption data were obtained at the Central Laboratory of Middle East Technical University (METU) with a Quantachrome Autosoib-l-C/MS apparatus over a relative pressure ranging from 10" to 1. The BET specific surface area, total pore volume, micropore volume, mesopore volume, and pore size distribution, PSD, of ACC were yielded by using the software of the apparatus.

Biomass obtained from the wastewater treatment plant of Middle East Technical University (METU) was used as seed in the experiments. In the acclimation of MOs to HMs, maximum concentrations of Cu2+ and Zn2+ reached during acclimation were decided from previous work [17,21], The literature showed that when these metals were present individually in the system, ASP failed to operate at steady state values of 15 mg/L for Cu2+ and 90 mg/L for Zn2+, respectively [5], Therefore, one-third of threshold concentrations of these metals (that is, 5 mg/L for Cu2+, and 30 mg/L for Zn2+) were used to constitute the combined threshold concentration for mixtures of copper and zinc ions. Acclimation experiments were performed by gradually increasing the concentrations of Cu2+ and Zn2+ to two, three and four times their combined threshold concentration. The optimum condition for a successful acclimation providing the growth of healthy MOs, as observed from the increase in turbidity values, was obtained at the concentrations corresponding to twice their combined threshold concentration [21],...
