There is a strong need to look at various possible designs that can be implemented to improve the single slope solar still performance through increasing the production rate of distilled water. Design modifications were introduced to the conventional solar still, involving the installation of reflec

The solar photocatalytic decolorization and degradation of Maxoline Navy 2 RM 200% basic dye in aqueous solution with TiO2-A (pure anatase) as photocatalyst in slurry form have been investigated using solar light. The removal of the dye was strongly enhanced by the addition of electron acceptors suc

Nowadays, in dry and rural areas, solar-powered membrane distillation (SPMD) technology is considered a feasible means for the production of pure water from brackish water. Prior to the design and construction of a SPMD pilot plant, there is a need to predict its performance theoretically by means o

In this paper, an attempt has been made to study a single stage solar desalination system to get a daily yield of 10 l of potable water. The experimental system consists of a flat plate collector, an evaporator, a single stage vacuum pump and a condenser. The input parameters such as solar irradianc

A parametric investigation was theoretically performed for the vertical multiple-effect diffusion-type solar still, which consists of a number of vertical partitions in contact with saline-soaked wicks with narrow gaps between the partitions, coupled with a heat-pipe solar collector. The proposed st

A basin-type solar still integrated with an inverted absorber asymmetric line-axis solar compound parabolic concentrator (CPC) is presented as a potential option for high-temperature solar distillation. A simple transient analysis of the system was carried out. Explicit expressions were obtained for

Solar distillation is one of the important methods of utilizing the solar energy for the supply of potable water to small communities where the natural supply of fresh water is inadequate or of poor quality, and where sunshine is abundant. Solar energy utilization in two different types of solar sti

Technology for solar desalination has been studied for a long time as a process friendly to the environment and also energy saving. We found a new aspect by diverting attention from industrial mass production systems to the consumer’s life-style and resource recycling problems. Thus, desalting solar

This work presents a computer program developed for sizing and simulating a solar-powered desalination station using the SMCEC principle. This is motivated by the absence of such software in this area. The computer package includes mathematical models for different compartments of the desalination u

a process flow sheet and a plan view are given. A preliminary study on further R&D actions and possible measures to enhance plant economy are also discussed.
