Desalination of highly concentrated salt water

A new process for the purification of very highly contaminated saline water, which often occurs in the Middle East and the Gulf States.
Drinking water is an increasingly scarce resource in many parts of the world. The standard technology for desalinating seawater is reverse osmosis (RO). This technology works, but it is very complex and too expensive. It cannot be used with high salt contents. That's why we thought about it and developed a technology that manages about half the costs of RO.
So far, this technology has only been successfully tested in the laboratory. However, it incorporates a standard technology that has been used successfully for decades and is therefore already equipped with a proof of concept. This technology have been recently registered for a patent in Germany (DPMA Munich).
This water can also come from petroleum processing, in which case the groundwater is additionally contaminated. The process substitutes reverse osmosis (RO), which is a standard process for converting seawater / ocean water to drinking water, but cannot be used for very high salt contamination. Our technology kicks in when RO has given up, as high salt concentrations cannot be handled with RO. Moreover, the cost factor is much lower with the new technology. One can assume up to 50% of RO costs as operating costs, depending on the case.
RO has about up to one third loss of water and the falling liquid retentate is waste and can only be processed with electrocoagulation (EC).
The process consists of two interlocking cycles that work more economically than reverse osmosis (RO). The technology can be classified under the title "Zero-Waste / Zero-Liquid-Discharge". There is no fraction in liquid form as retentate as with RO, but salt in solid form. Therefore, there is no water loss, which can often be up to one third with RO.
The operating costs are low - only an investment in the process equipment is necessary, which has to be made of stainless steel. The process can handle very high mass flows / volumes (m³/h) and already delivers drinking water quality in the process itself. It can therefore also be used on offshore islands in the shelf sea.
Since water scarcity is likely to increase in the coming years, we consider this technology a key technology for drinking water production.
