Lack of clean drinking water in rural areas is a huge problem during the occurrences of floods and other environmental disasters. Often, it takes a long time to transport potable water to these areas resulting in health issues for the residents. In this research, a solar power-based water purification system using PCM to produce clean drinking water in flood-affected areas or remote areas where potable water is difficult to obtain is proposed. Purification reduces the concentration of particulate matter including suspended particles, parasites, bacteria, algae, viruses, and fungi as well as reduces the concentration of a range of dissolved and particulate matter. The purification system available is not easy to get for poor people. So we are using a different technique for water purification system is solar distillation technique, which is very cheap and convenient. These Thermosyphon purification system is a modification of conventional solar still but the efficiency achieved is much higher then the conventional solar still. There are 5 major components in our design consists of Upper basin, Lower basin, Thermosyphon system, Diffusion still, and PCM chamber. The dirty water inlet is taken into Lower basin, upper basin, and diffusion still. Initially the temperature of water in the lower basin is low, so to increase the temperature of the water, thermosyphon loop system is connected with the lower basin. The energy from the lower basin is transferred to the condensing cover and the side walls of the tank which is been wasted to surroundings will be captured by upper basin and diffusion still. In diffusion still, there will be a successive plate, so energy from sidewalls will be evaporated and will be diffuse in a thin gap and it will get condense of the facing surface and that water will be collected in the outlet. We will be adding phase-changing material, which helps the purification to work on in absence of sunlight. So our basic design of the project is to increase the rate of evaporation and condensation process.
