“…Survey reveals that approximately 79% of available water is salty, 20% is brackish, and only 1% is fresh. Therefore, solar energy being free and in abundance is being utilized for the purpose of desalination of brackish water to produce drinking water [1,2].…”

An experimental investigation on a solar still with lauric acid as phase change material (PCM) is carried out to examine the effect of both the mass of PCM and basin water on the daily distillate productivity and efficiency of the system under outdoor condition. Basic energy balance equations are written to predict the water and glass temperatures, daily distillate productivity and instantaneous efficiency of the single slope solar distillation system with PCM. It is found that the higher mass of PCM with lower mass of water in solar still basin significantly increases the daily productivity and the efficiency. Therefore, the distillate productivity at night and on day for solar still with PCM increased by 127% and 30-35% respectively than without PCM one. Shukla et al. approach of the use of inner glass cover temperature for productivity prediction which has also been investigated, and the prediction shows relatively better agreement with the experimental data than outer glass cover temperature.

“…An analysis [58] discussing a technical and economic analysis of an MED plant, with a capacity of 80 m 3 /d, powered by a low-temperature geothermal source and installed in Kimolos, Greece showed that high temperature geothermal desalination could be a viable option. A study [59] presented results from an experimental investigation of two polypropylene-made HD plants powered by geothermal energy [60]. Recently, a study [61] discussed the performances of a hybrid system consisting of a solar still in which the feed water is brackish underground geothermal water.…”

“…A black-painted basin, sealed tightly with a transparent cover, stores the saline water. As the sun heats the water, the basin water evaporates and vapor comes into contact with the cool glass ceiling where it condenses to form pure water (Bouchekima 2002). The water is drained from the solar still for potable use.…”

E nergy is needed in various stages of desalination. Energy consumption directly affects the cost-effectiveness and feasibility of using desalination technologies for drinking water production. This chapter presents energy types, use, methods of conservation, and the potential use of renewable energy resources for desalination. Some of the information provided in this chapter may not be applicable to today's desalination energy issues. However, the information provides a comparison between costs associated with various energy sources as applied to desalination worldwide, and can be used as a reference for future energy development and use for desalination. Energy Needs and ConsumptionEnergy is needed in various stages of desalination. Desalination technologies use pumps in various stages of desalination, i.e., feedwater intake, treatment process, and discharge of product water and concentrate. Pumps consume a significant amount of energy. RO plants use pumps to pressurize feedwater passing through the membranes. Ion exchange plants use pumps to pass the feedwater over the resin, and use backwash pumps to clean and recharge resin beads. In electrodialysis, pumps pressurize feedwater to generate flow across the surface of the membranes. The amount of energy pumps consume depends on the type of process, the TDS concentration in the feedwater, the capacity of the treatment plant, the temperature of the feedwater, and the location of the plant with respect to the location of the intake water and concentrate disposal site.Each desalination technology is unique in design and mode of operation and it is rather difficult to compare energy consumption for different types of desalination technologies. Table 1 is a generalization of typical energy consumption for various technologies.The energy consumption for reverse osmosis plants depends on the salinity of the feedwater and the recovery rate. Seawater reverse osmosis plants require higher amounts of energy due to the higher osmotic pressure of seawater compared to brackish water reverse osmosis plants. The osmotic pressure is related to the TDS concentration of the feedwater. Electrodialysis plants use electric energy to desalt the water. For electrodialysis, the energy required is directly related to the TDS concentration in the water. Electrodialysis is economical only for brackish waters (TDS < 4000 mg/L). Energy Conservation and RecoveryA system's ability to conserve or recover energy is critical for implementing an economical desalination technology. The section below describes various energy conservation and recovery techniques. Methods of Energy ConservationPelton impulse turbines (PIT) and hydraulic turbochargers (HTC) are the most widely used devices for energy conservation in desalination plants (Manth et al. 2003). Reverse running pumps may be found in older facilities, but these pumps are least effective for energy conservation. Figure 1 shows the integration of a PIT with a reverse osmosis plant. Normally, the motor uses electric energy to drive the feed pum...
