Solar still

This paper aims to investigate the different parameters that affect solar still productivity when the solar still productivity is very low compared with other desalination systems, such as other thermal processes or membrane processes. These parameters include environmental, design and operational p

The aim of this study is to investigate analytically and experimentally the effect of using an induced atmospheric air, water heaters, external reflector and weather condition on the performance augmentation of humidification– dehumidification (HDH) system. This novel HDH system is a modified solar stil

Solar still desalination systems offer sustainable tools for fresh water production. However, their widespread application is often hindered by their relatively low production rates compared to other desalination methods. In this study, a simple amendment, in the form of a slowly-rotating hollow cyl

In this paper, we present a geometrical model to calculate the radiation reflected from an external reflector inclined backwards and then absorbed onto a basin liner of a basin type still. The effect of the inclination of the external reflector on the distillate productivity of the still with both t

There is a strong need to improve the single slope solar still thermal performance and increase the production rate of distilled water. Different types of absorbing materials were used to examine their effect on the yield of solar stills. These absorbing materials are of two types: coated and uncoat

This paper presents a theoretical analysis of a one step azimuth tracking tilted-wick solar still with a vertical flat plate reflector. The still is assumed to be rotated manually just once a day at southing of the sun. We performed numerical analysis of heat and mass transfer in the still to determ

Water scarcity and pollution pose critical situation in all walks of life especially in the developing countries. Among the available purification technologies, solar desalination process proves to be a suitable solution for resolving this existing crisis. This renewable energy technology operates o

A solar still is a simple desalination unit, but typical configuration is a sealed box with an angled glass top. Sunlight shining into the box heats water or liquid, causing it to evaporate. The moisture condenses on the relatively cool glass cover and runs down the sloped surface for collection. In

Single basin solar still is a popular solar device used for converting available brackish or waste water into potable water. Because of its lower productivity, it is not popularly used. Numbers of works are under taken to improve the productivity of the still. The still productivity depends on param

A sun tracking system was deployed for enhancing the solar still productivity. A computerized sun tracking device was used for rotating the solar still with the movement of the sun. A comparison between fixed and sun tracked solar stills showed that the use of sun tracking increased the productivity
