Development of Cassette-Type Water Treatment Package System for Emergencies

The concept of water security has become an important social issue and the need to deploy emergency management systems of water supply has increased. This study observes the water sources available for emergency water supply and the characteristics of the pollutant leakage into each water source. The study also reviews suitable combinations of treatment processes based on the observations and presents a water treatment system for emergency water supply to manage such situations quickly. The cassette-type water treatment system developed in this study modularized the water treatment equipment manufactured by various manufacturers for a specific space so that the process could be structured selectively. Each module was designed to treat the water independently, and featured self-diagnosis, automatic operation, intelligent process selection, and communication functions. Compared to the existing emergency water supply systems, the presented system could intelligently select an operational process according to the raw water properties, and the power unit for self-generation was designed in the form of a cassette, so that it could operate for 2.0 h or longer, even under the condition of no power supply. Therefore, it could be used in case of not only a natural disaster but also an interruption of the water service.
