Some lighter foreign matters or dust will float on the water surface. The existing filter device can not effectively filter these floating foreign matters or dust. Therefore, the purpose of this study is to design a surface filtration and sterilization device, hoping to provide hot spring, massage pool and swimming pool operators with good performance in water quality management. The structure of the design content includes: the tank body, which has a movable hatch cover, a central filter pipe and a filter screen layer, the filter material structure which is detachable, and a purified water output pipe connecting the holding space and the outside, and the water outlet is arranged at the bottom of the tank body, and the filtered and sterilized pool water is led into the purified water pipe for transmission through the central filter pipe and the filter material structure through the suction of the motor And then discharged into the pool water.

Hot springs are not easy to generate, how to deal with the used hot spring water and make it recycled has become a very important topic in this industry. The purpose of this study was to develop a hot spring filtration and sterilization device, to provide hot spring industry in hot spring water quality management has good results. The problem to be solved in this research and design was to use Titanium dioxide nano silver Antibacterial cloth for antibacterial dyeing and finishing powder the filter sterilization device was made of filter material structure, aiming at the spring quality of Carbonated spring or Sodium bicarbonate spring), The hot spring pool water is filtered and sterilized and re-introduced, so that the hot spring water could be reused without the doubt of hygienic safety. In order to solve the above problems, this research and development designed department discloses a hot spring pool water filtration and sterilization device, applicable to carbonated spring or sodium bicarbonate spring Its structure included: 1. barrel 2. central filter 3. filter material structure.

To improve business performance and achieve sustainable development through the concept of hot spring resource reuse, this study investigated the antibacterial effect of alginate-coated tea tree essential oil microcapsules and the effect of alginate microcapsules on the release of tea tree essential oil. The results revealed that 450 μm alginate/tea tree essential oil microcapsules (containing 720 ppm of tea tree essential oil) prepared using microfluidic assemblies effectively inhibited total bacteria, Escherichia coli, and Staphylococcus aureus in hot spring water. For alginate/tea tree essential oil microcapsules prepared under different conditions, at a fixed concentration of cross-linking reagents, the release time increased with the cross-linking time (10 min > 5 min > 1 min). At a fixed cross-linking time, the release time increased with the concentrations of cross-linking reagents (1 M > 0.5 M > 0.1 M). When the concentrations of cross-linking reagents and the cross-linking time were the same, the release time of cross-linking reagents increased with the strength of metal activity (Ca > Zn).
