The Performance of Trapezoidal Glass Cover Solar still during Monsoon Period of Tropical Environment

Seawater or brackish water desalination process using Reverse Osmosis as one of the current treatment technologies is expensive. A cheaper alternative is by using solar still. The paper presented the performance of solar still under tropical environment during monsoon period. The solar still was constructed using black stainless steel basin. Measurement of temperatures, solar intensities and distillate produce were recorded in the month of November and December, 2013, between 8 am and 6 pm. It was found that the distillate production rates obtained varied from 1.88 kg/m2/d to 2.26 kg/m2/d with efficiency of 37.7 %.
