碩士 / 國立交通大學 / 工學院工程技術與管理學程 / 100 / In Taiwan, natural water resources are more difficult to be held and the problem of industrial water supply is getting serious due to the influence of unusual weather condition recently and its varied topography. Seawater is easy to get and endless supply in Taiwan. Hence, the utilization of desalination of seawater can provide not only desalinated fresh water in people’s livelihood but also industrial water in factories. The aim of this study was to investigate the distribution of usage of water resources in central Taiwan and to analyze the practicability of substitution of desalinated water for industrial water supply in industrial parks. The work was based on method of inquiry and model of a small-scaled seawater desalination factory. The operating data of the experiment factory was collected and the effectiveness of technology of reverse osmosis (RO) process in desalination of seawater was evaluated.
The investigation results revealed that the percentage of required industrial water supply is about 80.2 in 2016 if the growth of economic achieves presume goal and even more vigorous in Taiwan. Moreover, the shortage of water supply in 2021 is roughly 19 tons per day in central Taiwan. The simulation results revealed that the operating cost in a desalination factory is about 59% in power, 19% in general operating, and 22% in chemicals. The average operating cost is near 17.27 NT dollars per unit, and it is currently near twice of fresh water in livelihood and still non-tolerable. Moreover, the correlative coefficient R was about 0.49 of the generated desalinated water to the required power supply. The value was not higher enough to indicate the physical relationship between these two factors resulting in some uncertain factors, such as conditions of desalinated operation, quality of seawater, training of operators, performance of equipment, or frequency of testing, et al. Notable, the simulation results indicated a fact that the more the amount of generated desalinated water the more the required power supply.
