Simulation and evaluation of water sterilization devices

Abstract

Treatment of water before consumption is needed to ensure that water quality and purity is achieved. Consuming untreated water can lead to waterborne diseases (such as diarrhea, cholera, and typhoid fever, etc.). It is unbelievable to know that a higher volume of earth water is unsuitable for human consumption because of naturally occurring activities (such as an earthquake, hurricane, and typhoon, etc.) or some human activities (such as throwing sewage, industrial waste, harmful fertilizer, and litter, etc.). This study aims to analyze water sterilization devices using the fuzzy PROMETHEE multi-criteria decision-making method. This method aid the therapist to obtain the most efficient and outstanding therapy that best address the symptoms shown by the patient. The method imple-ments groundwork for constituting a decision-problem, recognizing and evaluating its differences and co-action, and further features the leading alternatives and the reason behind it. The method is applied while evaluating and comparing several criteria such as safety, cost, efficiency, capacity, maintenance, and power consumption. To successfully implement this method, weight, and preference functions were utilized. The weight is set based on the importance of each criterion. With the decision lab, visual PROMETHEE program, the result indicating the most preferred device is gotten. The result shows ultraviolet sterilizer as the most preferred water sterilization device based on the assigned weight and criteria. This decision can, however, be adapted furthermore by assigning different weights and criteria of choice. With this study, it is important to note that the technique used is an efficient tool in multiple criteria decision making for water safety.
