Exploring Water Purification Techniques

Water Scarcity Challenge
Water Scarcity Challenge
Approximately 2.2 billion people lack access to safely managed drinking water. Water scarcity affects every continent, highlighting the need for effective water purification methods.
Nature's Filtration System
Nature's Filtration System
Nature cleans water through the hydrological cycle using evaporation, condensation, and precipitation. Wetlands, mangroves, and forests serve as natural filters, trapping sediments and absorbing pollutants.
Innovative Solar Purification
Innovative Solar Purification
Solar water disinfection (SODIS) harnesses UV light to kill pathogens in contaminated water. Transparent plastic bottles filled with water are exposed to sunlight for 6 hours, effectively improving water quality.
Graphene Revolution
Graphene Revolution
Graphene-based filters, just one atom thick, can effectively remove nanoparticles, organic molecules, and even salt from seawater, potentially transforming desalination and water purification processes.
The Role of Plants
The Role of Plants
Plants like the water hyacinth, with its vast root system, are used in phytoremediation to absorb toxins and heavy metals from polluted waters, offering a sustainable cleanup strategy.
Electrocoagulation Breakthrough
Electrocoagulation Breakthrough
Electrocoagulation introduces electric currents to water, causing contaminants to coagulate and be removed more easily. This method is effective against a variety of pollutants, including industrial effluent.
Fog Harvesting Technology
Fog Harvesting Technology
In arid regions, fog harvesting systems collect water droplets from fog, using large nets. This innovative approach can provide fresh water without the need for groundwater or rain.
