Drinking water desalination using low-cost Tubular Solar Still

Experimental Study on a Compound Parabolic Concentrator Tubular Solar Still Tied with Pyramid Solar Still

Indirect Solar Desalination: Value Engineering and Cost Benefit Analysis

This study examines the feasibility of indirect solar desalination in oil producing countries in the Middle East and North Africa (MENA) region. It relies on value engineering (VE) and costbenefit with sensitivity analyses to identify optimal coupling configurations of desalination and solar energy technologies. A comparative return on investment was assessed as a function of water costs for va...

A new method for water desalination using microbial desalination cells.

Current water desalination techniques are energy intensive and some use membranes operated at high pressures. It is shown here that water desalination can be accomplished without electrical energy input or high water pressure by using a source of organic matter as the fuel to desalinate water. A microbial fuel cell was modified by placing two membranes between the anode and cathode, creating a ...

Effect of air flow on tubular solar still efficiency

BACKGROUND An experimental work was reported to estimate the increase in distillate yield for a compound parabolic concentrator-concentric tubular solar still (CPC-CTSS). The CPC dramatically increases the heating of the saline water. A novel idea was proposed to study the characteristic features of CPC for desalination to produce a large quantity of distillate yield. A rectangular basin of dim...

Low Cost Solar Water and Space Heating Systems

Market penetration studies indicate that in the absence of tax credits, large reductions in the costs of active solar water/space heating systems will be necessary. A number of potential means for equipment and labor cost reductions are presented. The use of drainback systems with polybutylene pipe and a variety of low-cost collector concepts is discussed. The pros and cons of the various drain...
