TATA. Review on Tata Swach Ultima Ro +Uv Water Purifiers

The Tata Swach is a water purifier developed by Tata Chemicals, a part of the Tata group in India. Swach was designed as a low cost purifier for Indian low-income groups, who lack access to safe drinking water.The product is sold in three variants as Tata Swach, Tata Swach Smart and Tata Swach Smart Magic. Tata Swach was designed by Tata Research, Development and Design Centre ( TRDDC) and Tata Chemicals with contributions from other Tata group companies. In 2004 the company developed a water purifier called Sujal. Tata Consultancy Services deployed thousands of these filters in the Indian Ocean Tsunami disaster of 2004 as part of its relief activities.

Sujal was a very basic low-cost model which used rice-husk ash ( produced from heating rice husk in combination with pebbles and cement) . Activated silica and carbon is present in the ash; silica can reduce the turbidity of water, while activated carbon binds with and adsorbs non-polar impurities ( such as pesticides and fertilisers) .

However, the purification system did not have bacteriostatic or bactericidal properties and it was incapable of removing impurities such as lithium, alcohols, ammonia, strong acids and bases or inorganic substances like sodium, lead, iron, arsenic and nitrates.Dr. Muraly Sastry, Chief Scientific Officer of Tata Chemicals, confirmed that even though Sujal could successfully remove the odour, colour and particulate matter from impure water, many pathogens could not be eliminated.
