“…Energy recovery: Organic matter in wastewater can be used as a short‐term renewable carbon energy source. Minimization of waste sludge: Treating sludge as a resource rather than waste can reduce its environmental impacts and the demand for other non‐renewable sources of nutrients, organic matter, and energy (Oji et al, 2018; Sodamade et al, 2020; Srivastava & Singh, 2021).…”

The disproportionate populace progression in Lagos, Nigeria, and industrial undertakings have augmented the region's quantity and quality of waste. The magnitude of waste has initiated a disparaging alteration in the ecosystem of Lagos. Combining the population and volume of industrial waste has overwhelmed the city's existing wastewater management system (WWMS). This study offers an exploratory review of contemporary scholarship, which has reconnoitered sustainable WWMS as a conduit for significant interventions. The qualitative data was extracted from secondary and primary sources. Key informant interviews were conducted with the Lagos State Wastewater Management Office officials. A non‐participant observation approach was used to retrieve the Ogba Industrial Estate data in Ikeja. A plastic manufacturing plant in Amowo Odofin and familial residences in Bariga and Surulere served as empirical observation sites. The analysis embraced a sustainability framework, countenancing the construction of a holistic approach inclusive of environmental, political, economic, and social culpability. While the study established associated legal statutes, lawful compliance with WWMS was deficient. Verification includes frustration with multiple taxations, unpredictable government guidelines and scarce land. Derisory prioritization on environmental impact, scant infrastructure and inadequate technical knowledge are rationalizations for non‐compliance with WWMS in Lagos. The study has identified the urgent need for practical, sustainable WWMS to meet an explosive urban population's needs. The realization of cost‐effective WWMS promises to deliver social and environmental benefits while augmenting socio‐economic and health prospects in Lagos.

“…For technology supplementation to existing ASP-based STPs in the city to obtain e uent for inland surface water augmentation, WP in combination with micro ltration (MF) and reverse osmosis (RO) is suggested. Thus, the developed model may be used as a decision-making tool for planning a reuse-focused water reclamation program or for upgrading existing STPs as per resource availability and target reuse objectives (Srivastava Singh, 2022).

The objective of the present study was to compare the two systems of electrical coagulation and chemical coagulation in the treatment of waste water in cardboard industries. These two wastewater treatment methods were investigated with the help of analytical hierarchy process”(AHP). First, the research criteria were determined. These criteria included Economic, Efficiency, Energy consumption and Operation. Some criteria also had sub-criteria. After pairwise comparison and normalization of criteria, research options were weighted. The efficiency of these two methods to remove COD, TSS was investigated. The results showed that electric coagulation is higher than chemical coagulation in terms of efficiency with a weight of 0.75, economy with a weight of 0.737, Energy consumption with a weight of 0.667 and operation weight with a weight of 0.8. Finally, the electrical coagulation system was chosen as the final option with a weight of 0.74 and chemical coagulation as the second option with a weight of 0.26. In the treatment of cardboard waste, the consumption of chemicals is very high, so the electrocoagulation method can be very cost-effective. Also, operator error in this system was very low and work efficiency was higher.

“…For this purpose, they firstly provided the comprehensive review of the state-of-the-art in WWT. Srivastava and Singh [14] established a decision support model for the selection of most suitable WWTT from multiple criteria perspective in which the criteria weights are determined through Full consistency method. Salamirad et al [15] proposed an integrated decision support system using the best worst method and the behavioral Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS).…”

“…[47], Hezam et al [46], Rani et al [48]) have developed the extensions of classical MAIRCA method from fuzzy, intuitionistic fuzzy, interval-valued neutrosophic, Pythagorean fuzzy perspectives, but the these methods cannot deal with IVIF information in which the alternatives' information is represented in terms of intervals rather than the crisp numbers. ▪ In the literature, some authors (Ullah et al [13], Srivastava and Singh [14], Salamirad et al [15], Pennelilini et al [16], Ćetković et al [17]) have proposed different MCDM methods for solving WWTTs assessment problem. As an extension of IFS, the theory of IVIFS has the advantage that both membership and non-membership degrees are interval values and can used to characterize the uncertain information more flexibly due to its constraint condition.…”

Effective wastewater treatment has significant effects on saving water and preventing unnecessary water scarcity. An appropriate wastewater treatment technology (WWTT) brings economic benefits through reuse in different sectors and benefits the society and environment. This study aims to develop a decision-making framework for evaluating the sustainable WWTTs under interval-valued intuitionistic fuzzy set (IVIFS) environment. The proposed MCDM framework is divided into two stages. First, a new Hellinger distance measure is developed to determine the degree of difference between IVIFSs and also discussed its desirable characteristics. Second, an interval-valued intuitionistic fuzzy extension of multi-attribute ideal-real comparative analysis (MAIRCA) model is developed using the proposed Hellinger distance measure-based weighting tool. Further, the proposed model is implemented on an empirical study of sustainable WWTTs evaluation problem. Sensitivity and comparative studies are made. The results indicate that odor impacts, sludge production, maintenance and operation are the most effective sustainable factors and Microbial fuel cell (MFC) technology is the best WWTT followed by natural treatment methods.
