Tata Uses Nano Technology for Water Purifier
Tata Swach uses Rice Husk Ash (RHA) impregnated with nano (1 x 10-9) silver particles for safe and clean water. Tata Sujal also used RHA in combination with pebbles and cement. RHA, produced from heating rice husk, contains activated silica and carbon. Activated silica can reduce the turbidity of the water entering the filter and give a longer run for the system. On the other hand, activated carbon has the property to bind with non-polar materials while polar materials remain in aqueous solution.
