Abstract
[Display omitted]
The purpose of compiling this manuscript is to draw attention of young researchers on portable devices that yield drinkable water. The various techniques for potable water collection include solar stills, water distiller/condenser from air using radiative technique or desiccant material, bio-sand filter and steam generation by solar absorber materials are discussed in detail. The main vital parameters like solar radiations, type of material used, thickness of glass cover and its inclination, type of filter, diameter in case of nanoparticles, depth of water, pH of water, evaporation rate are under considerations for determining the performance of unit. Conventional desalination processes are not enough to fulfil remote area water requirements, so the utilization of solar energy is perceived solution using portable devices. Subsequently economic analysis of portable device is also presented for determining the performance of unit.
