“…It should be noted that many of the criteria adopted by them were more recently used in sewage treatment systems selection processes employing multiobjective analysis techniques (KARIMI et al, 2011;KALBAR et al, 2012;HUNT, 2013;CORNELLI (2014); MOLINOS-SENANTE et al, 2015). Thus, for Cr01 to Cr09 criteria, the alpha and beta values required to calculate the indifference and preference thresholds were, respectively, 0.05 and 0.00; and 0.15 and 0.00.…”

However, in sanitation management context with focus on water resources protection, it is necessary to adopt a methodology based on watershed territorial cut.…”

In order to determine required wastewater treatment plants (WWTP's) efficiencies, several methodologies have been proposed to assist the sewage treatment systems process selection, usually aiming to achieve economic objectives. However, in water resources problems solving, search involves multiple and conflicting objectives. This work used, for Pardo's river basin (Espírito Santo State, Brazil), water quality simulation model, optimization technique and multiobjective analysis for selecting sewage treatment systems, taking into account Brazilian environmental effluents Biochemical Oxygen Demand standards, imposed by CONAMA Resolution 430/2011. After proposing an optimization model that allowed the estimation of minimum organic matter removal efficiencies, a multiobjective analysis was applied by using the ELECTRE III method, which selected sewage treatment systems for localities responsible for domestic wastewater disposal in Pardo's river basin. The results indicated that keeping the effluents standards can produce treatment plants overestimation and inadequate allocated financial resources distribution for sewage treatment plants implementation. Treatment systems such as Submerged Aerated Biofilters (with Nitrification), Wetlands and Facultative Ponds were the most selected, considering different contexts appreciated in this work.

“…The MCDA approaches have been developed and applied to management, economics, social sciences and environmental sciences (Kalbar et al 2012). Among them, analytical hierarchy process (AHP) is useful for handling multiple criteria and objectives in the decision making process developed by Saaty (1977).…”

“…Among them, analytical hierarchy process (AHP) is useful for handling multiple criteria and objectives in the decision making process developed by Saaty (1977). AHP (subjective method) is used to select a preferred alternative using pairwise comparisons of the alternatives based on their relative performance against each criterion (Kalbar et al 2012). Another method is the technique for order preference by similarity to ideal solutions (TOPSIS), which evaluates the performance of alternatives through the similarity with the ideal solution developed by Hwang and Yoon (1981) (Mond and Rosinger 1985).…”

This study proposed a multi-objective environmental reservoir operation methodology (MOEROM) and applied the new methodology to the Three Gorges Reservoir (TGR) in China. The MOEROM directly incorporated the statistical water quality models in the objective functions to reflect the response relationships between reservoir operations and water quality in three tributaries (the Xiangxi River, the Daning River and the Xiaojing River). A real-coded genetic algorithm with self-adaptive crossover operators was employed to solve the environmental reservoir operation model. And four different MCDA approaches (AHP, TOPSIS, Fuzzy AHP, and Fuzzy TOPSIS) were proposed to evaluate the optimal operational schemes. The results showed that TOPSIS and AHP were more suitable for selecting the schemes than the others because of the larger fluctuations. To demonstrate the advantage of MOEROM, the environmental operation schemes were compared with traditional and practical operation schemes in 2013. The advantages of the environmental operation scheme over the others were that it would help reach a compromise between economic benefit, flood control and water quality improvement. In the future, more water quality indices, uncertainties in water environmental information, and more efficient algorithms would be further considered and researched.Water Resour Manage (2016) 30:3553-3576 DOI 10.1007/s11269-016-1370-2 Electronic supplementary

“…These findings are proof that South Africa's wastewater treatment systems are inadequate to meet the effluent required standards. This has resulted in the urgent need for the development and implementation of innovative systems to resolve the wastewater treatment constraints (Kalbar et al, 2012a). It is for this reason that interest has been sparked into the investigation of alternative wastewater treatment technologies for the treatment of wastewater.…”

Wastewater treatment will always pose problems if there are no new alternative technologies in place to replace the currently available technologies. More recently, it has been estimated that developing countries will run out of water by 2050. This is a course for concern not only to the communities but also a challenge to the scientist to find new ways of wastewater recycling. Water losses can be avoided through implementation of easy and inexpensive technologies for wastewater treatment. Environmental concerns over insufficiently performing septic systems and high expenses in the construction of sewer systems as well as their operations with centralized water purification systems have spurred investigation into the appropriateness of the use of wetland technology for wastewater treatment. Constructed wetland efficiency and potential application in wastewater treatment has been reported decades ago. However, the logistics and research for their commercial applications in wastewater treatment has not been documented in details. Research has shown that wetland systems can achieve high treatment efficiencies with regards to both organic and inorganic nutrients as well as pathogen removal if properly managed and efficiently utilized. This can have a profound effect in the management and conservation of our scarce and yet depleting water resources.
