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).

在电凝、生物、吸附和生物吸附过程中，哪一种处理方法对偶氮染料的去除效果最好?

几十年来，“哪种治疗方法是最好的?”一直是全世界许多研究人员的首要问题。因此，本研究旨在利用帝国竞争算法(ICA)优化处理模型，以去除酸性橙7 (AO 7)和酸性红18 (AR 18)为例，对生物、吸附、电凝(EC)和生物吸附工艺进行技术经济比较。膜测序间歇反应器(MSBR)、颗粒活性炭(GAC)和GAC-MSBR分别作为生物、吸附剂和生物吸附工艺。最便宜的是MSBR(0.02 ~ 0.08美元/立方米)，其次是GAC(0.03 ~ 0.63美元/立方米)。虽然MSBR渗透膜的质量可能不理想，但GAC和GAC-MSBR渗透膜的质量最好。除EC的运行成本高(≥1美元/立方米)外，电极在多次使用后需要更换，其成本约为550美元/立方米。本研究中，GAC-MSBR工艺对AR - 18的去除率为80-100% (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
