The resource management with value engineering technique: case study water distillation RMUTL-tak campus

Abstract

Pure water was consumed and insufficient that causes from the population continuous increasing. The water was contaminated with some pollutants. The most of science laboratory produced only the distillation water for experimental learning. In present, distillation technology was released a lot of wastewater. Therefore, a research group interested in applies to use value engineering for water resource management. This research collected the data, analysis of distillation water process, and designed of renewable wastewater for cooling process. The results shown that before improve system a distillation water and wastewater were found 3.7 l/h, and 140.3 l/h, respectively. For after improve system a distillation water was found only 3.82 l/h, and without wastewater. Furthermore, economical study found that the cost of water and electric were saved 394.23 bath/month when compared with old system. And the payback period was 114.16 month (9 years 6 months 3 days). Hence, the applied value engineering for water resource management could be saved wastewater 100 percent.
