CRAB DISTILLATION SYSTEM

To fulfil the portable water requirement of a family, the CRAB DISTILLATION SYSTEM solar still was constructed. It has rectangular central basin and four rectangular step basins attached on it four sides. The central basin has corrugated basin liner. Each rectangular basin on the sides of the central basin has five trays and trays are arranged in a step-wise pattern. The still was position at different angles and the position that produced the maximum distillate was determined. In the same way, the optimum basin was depth, heat storage material, wick material was also determined. External mirrors were used to focus additional solar radiation into the still. Finally the experiment was conducted by placing the still in optimum position and using the most productive water depth. Heat storage material and wick material. The distillate production from the still was 22.75 litters per day this sufficient to meet the entire portable water requirement of the family.
