Design Specifications
The TATA Swach filter is comprised of two parts. The upper part contains reservoir where the untreated water enters and is pre-filtered via the top mesh – TATA Swach MF membrane – which is a micro-mesh systems that remove the visible impurities. The lower middle portion has the TATA Swach Bulb to which the cartridge can be attached. The primary filtering component of the Tata Swach Smart water-purifier is the TATA Swach Bulb. The TATA Swach bulb is densely compacted with processed rice husk ash impregnated with activated silica coated with silver nanoparticles that destroys harmful bacteria and viruses from water. Another reservoir is placed at the lower end, which collects clear water. The whole system acts on gravity and electricity or constant flow of water is not required. The upper chamber can be easily cleaned. Depending on the quality of water about 1500 Litres can be filtered after which the cartridge can be replaced. Once purifying capacity is exhausted the Swach bulb fuses and prevents water from passing. The lower storage container has a maximum capacity of 15 Litres.The flow rate of the filter is 3-4 litres per hour. Total weight 1.7 kgs (3.75 lbs)
