This study aims to eliminate the issue of scheduled power interruptions by integrating Distributed Generation (DG) sources based on the available energy sources, which are Waste-To-Energy (WTE), in addition to the Photovoltaic (PV) sustainable source. The proposed system is simulated using the Open Distribution System Simulator (OpenDSS). The AutoAdd Optimization (AAO) technique was adapted to determine the optimal placement and size of the distributed generators. The findings indicated that the integration of WTE generation with solar PV plants result in power generation that is adaptable to variations in solar irradiation and fluctuations in demand, meeting roughly 50 % of the power demand in the Al-Gharab network throughout the day. This led to a 50 % decrease in the amount of electricity sourced from the national grid.

Polymer-based membranes offer a promising solution due to their potential for high selectivity and energy efficiency. However, achieving optimal gas separation performance often requires overcoming the limitations of individual polymers through modifications such as polymer blending. In this study, PSf/P84 blended membranes with low P84 content were fabricated using the phase separation technique with a mixture of N-methyl-2-pyrrolidone and tetrahydrofuran as solvents. The effect of varying the mass ratio of PSf to P84 on membrane characteristics and gas separation performance was investigated. Characterization techniques included FTIR, XRD, SEM, TGA, Water Contact Angle (WCA) measurement, and mechanical property testing. Gas permeation tests were conducted with single gases at room temperature and 1 bar pressure. The results revealed that the addition of P84 increased membrane thickness, Young's modulus, and thermal stability, while decreasing d-spacing, dense layer thickness, hydrophilicity, tensile strength, and elongation. The F<sub>index</sub> values, indicating the competence of the blended membranes compared to the ideal quality, demonstrated the positive impact of P84 addition on gas separation performance compared to pure PSf membranes.

It proposed using aerobic biological treatment for the first effluent containing tetramethyl ammonium hydroxide and chemical-physical processes for the other two streams having fluorides, phosphates, nitrates and acetic acid. The novel integrated process significantly reduced environmental impacts by an average of 50 % compared to current disposal methods. The economic analysis indicates a 30 % reduction in treatment costs for the first effluent and lesser reductions for the other two effluents. The study revealed that treating all three effluents in an integrated manner is cost-effective, reducing investment and operating costs.</p></div>","PeriodicalId":34388,"journal":{"name":"Case Studies in Chemical and Environmental Engineering","volume":"10 ","pages":"Article 100854"},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666016424002482/pdfft?md5=bc22da73a025c5e8ed567abfb8abb705&pid=1-s2.0-S2666016424002482-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141847199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
