Abstract :
As is generally known, water could purify to its natural substances by performing basic wastewater treatment (WWT). Despite many WWT technologies available nowadays, experts have difficulty selecting the most suitable technology due to so many criteria that governed the selection. The paper aims to identify the most suitable WWT technology using the multi-criteria decision making technique, fuzzy simple additive weighting (FSAW). Three decision makers which is knowledgeable in WWT technologies are appointed to evaluate and provide information regarding the WWT technologies and its affiliated criteria. Decision makers were asked to rate the criteria for every WWT technology within the framework of FSAW. The seven-step algorithm of FSAW has successfully identified anaerobic digestion as the most suitable technology in WWT. An implication of these findings is that both potential WWT technologies and criteria should be taken into account when considering the most suitable technology that could bring benefits to community.
