Abstract


The present paper deals with the assessment of water treatment capacity of solar system designed with special features. Taking stock of the situation in respect of portability of water in a sample water distressed state of India, it is noticed that the TDS in available water is mostly above the limit of tolerance for drinking purpose. Thus the capability of designed solar system in reducing TDS content as well as in managing the other water contaminants in the region under study has been investigated.  The paper studies the energy and exergy efficiencies of the solar collector and those of the solar stills. Moreover, study is conducted in cases of coupled flat plate- solar still system and standalone solar still designed for the present experimentation to qualitatively assess the efficacy of the solar water treatment system in addressing the concern for deterioration of water in respect of increase in TDS due to unwarranted mixing of RO rejects with major water resources. A critical study on the adoptability of newly designed evaporation technique is reported in the present paper. It is observed that the presently designed solar water treatment can efficiently purify the contaminated water. The results have shown the coupled system bears a slight edge in treating the polluted water over the stand-alone system.
