Water scarcity and solar desalination systems in the Eastern Mediterranean region: a case of Northern Cyprus
Water is definitely physically scarce in the Middle East and North Africa (MENA) and the Mediterranean region with less than 1000 m3/capita/year. Water scarcity in these regions is a function of both water supply and water demand as both applies in most of the countries. Using the Falkenmark indicator the Mediterranean region will see increased deterioration in the availability of renewable ...

Technical and economic evaluation of an off-grid solar desalination system in Myanmar
Myanmar is a unique country where the majority of the people live in rural areas, away from grid electricity and reliable water supplies. The penetration of grid electricity in rural areas is minimal and even then it is often erratic. This paper focuses on the challenges of transitioning from an electricity-poor country to a renewable energy based-economy augmented with photovoltaics (PV). ...

The Desolenator – Turning sunshine into water
As resources go, water is probably the most vital resource we have in the whole world. Unfortunately, one of the most prominent problems in the world is that not everyone has access to it. This is where the team behind the Desolenator are hoping to make an impact, by turning sunshine into fresh, clean drinking water. The Desolenator is the first easy to use, low cost, solar powered desalination ...

Naturally endowed oxide nanoparticles from carbon ash in Saudi Arabia
Chemical analysis of carbon ash powder obtained from water desalination plants in Saudi Arabia has revealed that 84.3% of the ash is pure carbon while the remaining percentage is combinations of oxide materials, mainly silicon and aluminium. These oxides were extracted by sintering the ash powder at 900°C. Shape and size of the obtained oxide powder were determined by transmission electron ...

Experimental evaluation of a low pressure desalination system (NF-PV), without battery support, for application in sustainable agriculture in rural areas
Desalination driven by solar energy represents an appealing solution for agricultural irrigation in remote areas. In this work, a desalination system based on a photovoltaic-powered nanofiltration (NF-PV) membrane is studied. The experimental work explored the effect of the influent concentration and solar radiation on permeate production, energy consumption, recovery rate and quality of the ...

Feasibility investigation of coupling a desalination prototype functioning by Aero-Evapo-Condensation with solar units
The rural regions of south Mediterranean countries suffer from problems of drinking water supply. However, the majority of these regions have important resources of brackish salt water. Thus, brackish water desalination on a small scale presents a potential solution to this problem. For this reason, a number of small desalination prototypes are being developed worldwide. Bourouni et al. have ...

Greenhouse based desalination for brackish water management using bittern evaporative cooling technique
The Arab region is characterized by arid and semi-arid conditions with very limited renewable water resources. Most of the surface water comes from transboundary streams and most of the groundwater resources are fossil in nature. Water quality degradation and excessive use of pesticides and herbicides in agriculture pose severe environmental and health risks. The underlying research is a joint ...

Micro, Small, and Medium Enterprises: Key Players in Climate Adaptation
In most developing economies, Micro, Small, and Medium Enterprises (MSMEs) employ up to 78 percent of the population and account for approximately 29 percent of the national GDP. Their presence in communities throughout the world– big and small, rural and urban – allows them to get products and services to hard-to-reach populations. This market concentration and high level of ...

Can saltwater quench our growing thirst?
An increasingly water-stressed world takes a new look at desalination. It seems simple enough: Take the salt out of water so it’s drinkable. But it’s far more complex than it appears at first glance. It’s also increasingly crucial in a world where freshwater resources are progressively strained by population growth, development, droughts, climate change and more. That’s ...
