Elemental Water Makers
Elemental Water Makers has developed a solar-driven mini desalination plant suitable for use in off-grid rural areas. The plant is delivered in a container for speed and ease of installation and maintenance. Different sizes are available. Water production ranges from 5,300 to 40,000 liters a day. The process utilizes reverse osmosis technology. By reusing residual energy from the brine (the saltier water flow), energy input and number of solar panels can be reduced. The company also provides a desalination technology that uses solar or wind energy to pump seawater into a tank positioned high on a hill. This is so that the system may use gravity to provide pressurized seawater for the reverse osmosis process. As this process is designed for continuous operation, storing water inside an elevated tank has an advantage with regard to fluctuating renewable energy technologies by providing a flow of seawater that is constant.
