Solar thermal pasteurization: a simple way to disinfect water.

Abstract

This work is a review of a simple system for solar water pasteurisation with natural circulation discussed in our recent papers where it was designed, sized and simulated in different locations where the need for safe drinkable water was evident. Such model includes the full thermo-hydraulics, and the exergy and exergo-economic balance. In this report we critically analysed the simulated results in terms of productivity of the system and of daily and annual-average costs of purified water in order to deduce its potential socioeconomic impacts in the proposed contexts.
