CASCADE-TYPE SOLAR DISTILLER FOR BRACKISH WATER POTABILIZATION

Solar distillers are excellent means of obtaining fresh water and this studypresents the results of using a cascade-type solar distiller to remove salts andimpurities from groundwater. Using this model, a maximum hourly productivity of269.23 mL.m-2and an accumulated productivity per distillation unit area of 3,025.40mL.m-2.day-1 were achieved. Furthermore, all the physical-chemical parametersanalyzed showed significant reductions, falling below the maximum values permittedby national and international legislation. Therefore, the model presents itself as agood alternative for obtaining fresh water for isolated communities, with low cost,easy operation and high yield.
