Solar Distillation Unit Coupled with Water Lens Concentrator

One of the main problem that the world faces today is shortage of portable water. An efficient distillation system integrated with concentrated solar collector is developed in this work. The objective of this project is to increase the yield of distillate output in cost effective manner by design an active single basin double slop solar still with water lens. Water acting as lens, which can be substitute for other solar concentrated systems in an economical way. The solar radiation is concentrated at a point by passing through the water lens. The water lens is developed by pouring water on the transparent thin sheet. The concentration of focus point depends on water lens curvature. And effectively utilize the energy from the water lens concentrated copper collector to increase the temperature of water in the still basin. The water vaporizes at pressurization temperature and these vapours are sucked using a suction pump and passed through the condenser. The condensate water outlet is the purified water from the system.
