Water scarcity is a global issue confronting the present generation, particularly acute in arid regions such as Palestine. Treated wastewater reuse recognized strategic solution. The challenge obtaining effluent quality that meets requirements of area how to select best treatment technology. A multi-criteria decision-making method necessary for assessing sustainability different technologies. This study selected most sustainable secondary technology could produce agricultural at Rafah plant Gaza Strip. Evidential Reasoning was applied evaluate sand filters, constructed wetlands, activated sludge, and bio-tower evaluation based on four dimensions thirty-five indicators. indicators were obtained from review related literature validated by experts. Using questionnaire, judgment local experts (professionals working project, university professors, members NGOs) used qualitatively. Data analysis done using Intelligent Decision System Expert Choice software tools. utility interval-based evidential reasoning ranking technique rank options with without ignorance follows: wetlands > filters bio-towers sludge. Constructed ranked alternative, minimum 0.7345. environmental dimension, relative weighting 60.4%, dimension greatest influence alternatives.

Urban wastewater management in rapidly growing cities presents a significant challenge. Traditional centralized systems are unable to keep pace with increasing urbanization and generation. This manuscript case study conducted Yangon, aimed at investigating the feasibility potential benefits of approaching decentralized treatment system (DEWATS) as an alternative solution. DEWATS (CWTS) cases were observed for performance, operational efficiency, environmental benefits. Field studies, interviews municipal personnel, discussions residents also conducted. Residents using Yangon value its advantages willing invest sustainability. Those who use concerned about high costs unreliability. Results from sustainability assessments showed that obtained higher total scores than CWTS. Based on Weighted Sum Methods three scenarios, ranked first has been shown be sustainable solution across environmental, social, economic, technical aspects. provides strategy urban planners decision-makers option management. The evidence could support accelerating provision plants encourage willingness pay.

Existing probabilistic hesitant fuzzy set (PHFS) measures are constructed using two information measures: hesitancy and unwrapped probabilities. We argue that unifying these semantic terms in PHFS theory is not logical. introduce a new class of for PHFSs, which address the logical wrapping sets (HFS) probability. propose several similarity use Triangular norm operator. consider relationship between entropy represent axiomatic definition measures. Finally, we case studies to demonstrate applications describe multiple-criteria decision-making algorithms. The last step devoted ranking procedures: one based on score function alternatives other relative closeness alternatives. This contribution describes uses illustrate how they can be applied processes.

RSM modelling has been applied in this study to understand the effects of inter-electrodes on performance electrochemical reactors removal pollutants. selected because it ability predict more than one parameter targeted variable. Thus, used article model spaces (IES) (4 10 mm) and treatment time (TT) (5 – 55 min) electrocoagulation (EC) cells remove phosphate from water. The results showed best was 92.5% at I-ES 4 mm TT 50 min. High agreement noticed between experimental predicted removals (R 2 = 0.984).

Current energy demand for wastewater treatment is very high and expected to increase in the next decade. As climate change poses a challenge too, renewable options this industry are needed. Studies hydropower assessment addressed governance stakeholders have shown that some mechanical might be recovered from wastewater. However, none of them applied sustainability approach. Neither decision-making level was considered. The objective work present methodology, developed case study, with novel approach, including all these considerations. After analyzing context region proposed methodology includes three dimensions sustainability: economic, environmental, social. Firstly, group 186 plants, selected according their management model. Based on technical feasibility, 34 potential sites were identified. Secondly, obtain perspective, survey suitable criteria conducted. Then, multi-criteria method, aligned existing guidelines, applied. results show that, framework, an interesting option consider decarbonization systems. could directly design methodologies adapted context.

Abstract The present study investigates the production of nano-activated carbon from banana peels mixed with nylon 6.6 and polyethene. carbonization process was carried out by mixing accurate percentages different ratios 66 a suitable amount potassium hydroxide. fusion carbonization, without solvents, used in this paper to decompose mixture, releasing amino carboxylate roots that can easily react chains. prepared characterized using technologies, including SEM, AFM, FT-IR, EDX technologies. results showed produced has spherical particles pore size 1.21 nm surface area 1,071.7 m2/gm. Additionally, it noticed, FT-IR spectrum, does not contain any active groups, which means is an inert material. X-ray analysis new made (78.57%) oxygen (21.43%).

Abstract Cement is amongst the most polluting materials utilized in building sector, contributing to a variety of hazardous pollutants, including greenhouse gas emissions. This raises health impacts related manufacture cement. As result, substitute substance for conventional cement with low environmental effects and better characteristics required. The purpose study would be look at consequences using supplementary cementitious (SCMS) concrete mix partially. employed silica fume (SF) kiln dust (CKD) as materials. Several mixtures were created by substituting combination SF CKD three proportions which that 25%, 35%, 45% within curing periods (one week four weeks); tested. ultrasonic pulse velocity (UPV) test has been used investigate mixture’s strength this study. findings show optimal proportion replacement involvement ranged from 25% 35%. specimens improves when increases percentage, while larger amounts these by-products begin lower specimens.
