Solar Powered Water Purification Using a Natural Coagulant

Accessing clean, safe drinking water is still a problem for many people worldwide. Numerous technologies for filtering and purifying water demand more electricity, energy, or resources. As the environment continues to change, these difficulties will only get worse. Due to the depletion of water supplies and the fear mongering surrounding environmental degradation, water treatment is currently one of the main research areas. This has forced the upgrading of conventional water treatment technologies toward recycling and reuse. They function by neutralizing the charge by polymeric bridging, an adsorption process. The work offers particular information about the coagulation properties of natural coagulants, fabricating a solar powered water purification system at lower maintenance cost, where sand, pebbles, and charcoal are used for physical impurity filtration, water is preheated using heating coils, where moringa seeds act as a natural coagulant and solar energy is used to power the heating coils and UV light source. Total Coliform bacteria causing illness were completely absent and parameters like TDS, pH, and Turbidity have reduced from 309.6 mg/L, 7.4, 10.8 NTU to 274.4 mg/L, 7.2, 1.2 NTU, respectively. This is the cheapest water purification system that can be used in rural areas with household containers, Moringa (drumstick) seeds, and solar panels. The use of natural coagulants, which are widely accessible, affordable, simple to use, biodegradable, non-toxic, environmentally friendly, efficient, and produce less volumes of sludge, is a sustainable substitute.
