GREENBMG'S Water Desalination Methods and Treatment Technology

As ecological conditions take a turn for the worse, the world is faced with issues that require fast-acting solutions. One of the issues that we are facing is fresh water scarcity. This affects arid regions that do not experience much rain such as the Middle East and parts of Africa. These regions lack freshwater resources and use energy-intensive ways to desalinate their water supply.  Another issue is the lithium shortage in the Western regions. As electric vehicle adoption is increasing, the demand for lithium is sky-rocketing. Lithium demand is expected to increase from 320,000 tones to 212% by 2025 ( link Forbes, 2021).

GREENBMG has proposed low-cost sustainable water desalination methods to produce desalinated water from seawater, while simultaneously separating the salt in order to acquire raw materials such as lithium and magnesium. There are two ways to generate enough thermal energy for the water desalination plant: 1) Creating a solar farm of atmospheric vacuum tube heaters and combining that with GREENBMG’s reflecting tracking mirrors to concentrate the light energy. 2) Solar concentrated hybrid PV-thermal collectors.

In the proposed desalination plant, a multistage thermal process is considered that may be

combined in series with reverse osmosis. A few solid sea salt basin-extraction points would be

selected for the purpose of separating out a salt grade for further processing and obtaining marketable by-products such as magnesium, lithium.

GREENBMG’s patent-pending system simultaneously solves the issues of freshwater scarcity and the shortage of raw materials such as magnesium and lithium. By using this method, two big issues in opposite regions can move towards being solved in a sustainable way.
