Concentrated solar systems can help the Middle East and North Africa make sure they have enough water.
This solution aims to provide long-lasting, cost-effective, strong, and easy-to-use technology that cleans and distills wastewater and other water sources that can’t be used or are contaminated to make clean, pure, and safe water for places that need it. Concentrated Solar Multi Effect Distillation & Dewatering Systems (CSMED) use solar thermal energy to clean water from a variety of sources, such as agriculture, industry, mining, or municipal wastewater, brackish bore and hyper-saline water (including salt lakes), seawater, and even mine tailings dams. The clean, safe water can then be used again in agriculture, mining, and industry. This takes pressure off of freshwater sources, which are becoming more and more scarce. It can also be used to provide safe drinking water or to add to it when needed. It can also be used by the government and local businesses, or it can be put back into the natural landscape. Reclaiming, cleaning, and reusing water reduces the chance that contaminated wastewater will leak into soils, waterways, groundwater, or the ocean.
Positive facts about CSMED
Each CSMED unit can supply around 10,000,000 litres of distilled water p.a to where there is need from otherwise unusable sources, reducing stress on available fresh water sources.
Each CSMED unit can provide enough distilled water per day at source and off grid for in excess of 3,000 kg of green hydrogen production
The CSMED units utilisation of Solar Energy as the primary source is estimated to result in 180MT – 350 MT of CO2e savings p.a. per unit when compared with fossil fuel powered alternatives
The CSMED Dewatering system can provide Zero Liquid Discharge (ZLD) solutions that can eliminate environmental impact of concentrated brine discharge into the environment
At Scale, CSMED Levelised Cost of Water is calculated to be in line with current costs of tap water in some regions
In some cases, for example, in remote communities, the CSMED cost of water can be up to 70% cheaper when compared with current supply practices
In some regions the CSMED units used to process contaminated water on site can save customers around 90% on their current clean water supply costs
