In this study, municipal wastewater effluent (MWE) as a source of water for use in the CTTPP was evaluated by determining the water quality index. 22 MWE quality parameters were considered in terms of their potential effects on cooling towers. The relative weight of the parameters is calculated by the analytical hierarchical process (AHP). The analysis of water classification was done by using the fuzzy inference system (FIS). In the fuzzy logic approach, the trapezoidal and triangular membership functions and the Mamdani inference system were used, and the final rules consist of 240 rules. The center-of-gravity method is used for the Defuzzification of the results. The values obtained from the cooling tower effluent quality index (CTEQI) based on the FIS were generally more stable than the values from CTEQI based on the traditional system. The outcomes of this study established that the quality of effluent entering the cooling towers in a Shahid Moftteh power plant in the Hamadan (effluent sampling site) is moderate to good condition (annual fuzzy index 50–90, average annual traditional index 79.52–95.99). This research result reveals that CTEQI can be counted as a general tool for evaluating the quality of effluent that use in the CTTPP and can be used with confidence for this purpose.</p></div>","PeriodicalId":23714,"journal":{"name":"Water Resources and Industry","volume":"29 ","pages":"Article 100207"},"PeriodicalIF":5.1,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48555860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, magnesium oxide nanoparticles (MgO-NPs), synthesized from low-cost and readily available magnesite, were used for the treatment of real TWW under batch laboratory conditions. The optimum treatment conditions were 90 min contact time and 10 g MgO-NPs dosage per L of real TWW, under ambient pH and temperature. Results were underpinned by state-of-the-art analytical techniques, including ICP-OES, XRD, XRF, and FIB/EDS-SEM, along with geochemical modelling (PHREEQC).

The underlying mechanism for contaminants removal is linked to the scavenging of metals by the MgO-NPs, forming complexes, in combination with alkalinity addition (through MgO dissolution) that lead to contaminants precipitation. The PHREEQC geochemical model confirmed the existence of divalent, trivalent, oxyanions, and multivalent chemical species in MgO-NPs/TWW solution, including complexes. Contaminants attenuation was achieved through precipitation, co-precipitation, adsorption, and co-adsorption, while these were removed as hydroxides, sulfides, carbonates, oxide, and oxyhydrosulfates. Overall, results highlight the great potential of MgO-NPs for the sustainable management of real TWW.</p></div>","PeriodicalId":23714,"journal":{"name":"Water Resources and Industry","volume":"29 ","pages":"Article 100205"},"PeriodicalIF":5.1,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46585109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
