EVALUATION OF SOLAR DISTILLER AT DIFFERENT TILT-ANGLE AND WATER TYPE

A solar distiller at different tilt angle was fabricated to produce potable out of fishpond water, rainwater and seawater. This study was conducted to evaluate the performance of solar distiller at different angle and water type. Fish pond water was collected at the outlet of freshwater fishpond, rainwater was collected by catching the rain water from the putter and sea water was collected from a sea water bodies and it was subjected to eleven-hour solar distillation. Data such as ambient temperature and volume of distilled water produced was collected every hour. After three trials for cach water samples, the 40° angle distiller had a mean distillation rate of 15.58 ml/hr for pond water, 13.79 ml/hr for sea water and 14.85 mL/hr for rainwater respectively. The 40° angle distiller also had the higher mean total volume of distilled water produced than to other set-ups. The performance of all setups for all of the solar distillers was affected by weather conditions, tilt-angle of the condensing glass and the hardness of the water samples. For a more reliable result, it is recommended to conduct the distillation process simultaneously for all set-ups and water samples to control the effect of the variation of the weather condition.
