The water available in nature contains numerous contaminants such as physical, chemical, and microbiological that make it unfit for human consumption, so the task of water purification is to make the contaminated water safe to drink.
Water purification is a complex process and highly dependent on the nature and level of contaminants in it. Water purification in which reclaimed, contaminated, suspicious, and polluted water is processed and cleaned to make it suitable for reuse for drinking or home use. Some of the contaminants may pose health hazards while others may impact their smell, taste, and appearance.
Various international organizations like EPA and WHO provide standard levels of impurities in the drinking water. To comply with the standard requirements, the number of water purification technologies [reverse osmosis, electro-deionization—EDI, sedimentation, ultrafiltration, ion exchange, biosorption, and ultraviolet (UV) light] were used for many decades.
These purification technologies remove particles and give a clear appearance to water in addition to the improvement in its smell and taste.
Earth Power Group has been researching and developing the new principles, functioning, and the selection suitability for water purification technologies and presents best and natural possible methods.
Our distillation concept imitates the same natural process of the water cycle of our planet but enhances it with technology. Nature's water cycle depends on water molecules to become excited and dissipate into the atmosphere to ultimately return as precipitation.
The key to our systems is the use of solar technologies that provide both electrical energy (7kWe) and thermal energy (18kW) (per hour 24/7) as a standalone CHP power system with thermal storage, this way our systems work and produce freshwater in remote locations of our planet.
The second piece is a Forced Rapid Evaporation System that is the system we developed, let ultrasound and nanobubbles utilized in combination first-ever for the best purification cycle.
The system delivers up to 500,000 liters freshwater over a 24-hour-period. i.e., the energy cost is 0.036 watts of thermal energy and 0.014 watts of power per liter freshwater. The water source can be high salinity, brackish, chemically contaminated, and even petroleum-contaminated. The system also removes nano and microplastics.
Competing technologies that use some of the similar ideas, such as ultrasound, to fracture the water into smaller molecules. However, our systems use both ultrasound and nanobubbles in combination and derive all energy needed from the Sun, as a standalone CHP power system with thermal storage, hence, the system works and produces freshwater in remote locations.
The increased water quality, and low maintenance costs, thus higher socio-economic impact and improved sustainability, are significant advantages of our systems.
