This work aims to design and evaluate a large-scale seawater RO desalination plant using a commercial computer software. Key design parameters and operating conditions of the seawater RO plant are considered, selected, and inputted into the software. The performance indexes of the RO plant when operating under the design parameters and conditions are obtained and analyzed.

From ancient times, water has always been considered an important resource that played crucial roles in the rise and fall of human civilizations. For its essential and irreplaceable parts on the health, dignity, and prosperity of people, the access to water has been recognized by the United Nations as an important human right, and could significantly affect the realization of other fundamental human rights.

In this preliminary study, black spinel-carbon nanocomposite was synthesized and investigated for improved solar radiation absorbance aimed for the solar-driven integrated MD seawater desalination process. The black spinel-carbon nanocomposites were based on black spinel CuCr2O4 doped with various Fe3+ content. The black spinel-carbon nanocomposite was synthesized using the hydrothermal method and was characterized with respects to structural morphology and radiation absorbance properties.

Desalination is one of the several ways which have been used to mitigate this problem, and Reverse Osmosis (RO) is generally taking over as the preferred technique of desalination because of its generally higher efficiency and better quality of water produced using generally lower energy.

The width of the air space was controlled by the change in the number of plastic mesh in the permeability chamber. The results showed that the quality of permeate solution was identical with the quality of normal distillate water and the desalination efficiency of AGMD module strongly depended on the feed temperature, air-gap. The optimum condition found was 60 °C of feed temperature and air-gap width of 5 mm, then the water recovery flux reached 2.5 L.m-2 .h-1 .

The conversion of inefficient agricultural and forest land to rice - shrimp farming model in the Mekong Delta in general and Ca Mau province in particular has brought remark benefits in terms of economic development. However, the introduction of salt water into some freshwater regions have created environmental problems, which is not only impact on shrimp farming but also on many other agricultural ecosystems.

Although Egypt has already reached the water poverty limit, it possesses a high potential of brackish groundwater available from different aquifers. All Arab countries lie in the best sun-belt region in the world and Egypt has the highest number of sun hours all year round. Solar energy for groundwater desalination is an independent infinite energy resource; it has low running costs and reduces the contribution of greenhouse gases (GHG) to global warming.

The current water shortage in Egypt is 13.5 Billion cubic meter per year (BCM/yr) and is expected to continuously increase. Currently, this water shortage is compensated by drainage reuse which consequently deteriorates the water quality. Therefore, this research was commenced with the objective of assessing different scenarios for 2025 using the Water Evaluation and Planning (WEAP) model and by implementing different water sufficiency measures. Field data were assembled and analyzed, and different planning alternatives were proposed and tested in order to design three future scenarios.

The average water capture efficiency was 80.5%, the salt elimination efficiency of the system was about 99.99%, and the salinity of the output water was below 2 ppm. The results are still far from ideal, but they indicate a potential solution for coping with the shortage of fresh water in coastal areas.

The connection between operating temperature and membrane scaling/cleaning during an air gap membrane distillation (AGMD) process of seawater has been systematically elucidated in this study. Experimental and mathematically simulated data demonstrate the profound influences of feed salinity and membrane scaling on water flux at various operating temperatures.
