Abstract
For decades, “Which treatment process is the best?” has been the primary question for many researchers worldwide. Therefore, this study aims to optimize the treatment models using the Imperialist Competitive Algorithm (ICA) to achieve a techno-economical comparison of biological, adsorption, electrocoagulation (EC), and bio-adsorption processes as examples in Acid Orange 7 (AO 7) and Acid Red 18 (AR 18) removal. Membrane Sequencing Batch Reactor (MSBR), Granular Activated Carbon (GAC), and GAC-MSBR were selected as biological, adsorbent, and biological-adsorption processes, respectively. MSBR was the cheapest (0.02–0.08 US$/m3) followed by GAC (0.03–0.63 US$/m3). Although MSBR permeates may not be of desirable quality, GAC and GAC-MSBR permeate offer the best quality. In addition to high operating costs in EC (≥1 US$/m3), the electrodes should be changed after several usages, which cost approximately 550 US$/m3. In this research, GAC-MSBR, as an effective process, had 80–100% AR 18 removal efficiency (0.14–0.16 US$/m3).
期刊介绍:
Water Resources and Industry moves research to innovation by focusing on the role industry plays in the exploitation, management and treatment of water resources. Different industries use radically different water resources in their production processes, while they produce, treat and dispose a wide variety of wastewater qualities. Depending on the geographical location of the facilities, the impact on the local resources will vary, pre-empting the applicability of one single approach. The aims and scope of the journal include: -Industrial water footprint assessment - an evaluation of tools and methodologies -What constitutes good corporate governance and policy and how to evaluate water-related risk -What constitutes good stakeholder collaboration and engagement -New technologies enabling companies to better manage water resources -Integration of water and energy and of water treatment and production processes in industry
