Exploitation of solar energy collected by solar stills for desalination by membrane distillation

摘要

The aim of this work was to evaluate the technical feasibility of producing portable water from simulated seawater by integrating a membrane distillation module with a solar still. The relatively hot brine in the solar still was used as a feed to the membrane module. The syner- gistic action of the solar still and the membrane module in the production of potable water was quantified. For this purpose, two types of experiment were conducted, indoor experiments and outdoor experiments. The sensitivity of the permeate flux tot he brine temperature, flow rate, salt concentration and solar irradiation were all investigated.
