The RO technology uses a semi-permeable membrane for the purification purpose that allows only water molecules to pass through it, while blocking the dissolved and suspended impurities. RO technology is used for purifying water that has high content of salt. The UV technology is basically used for making water germ free and fit to drink. The UV purification kills virus, bacteria and other waterborne disease causing germs. The process involves a UV bulb fitted inside the water purifier that throws ultraviolet rays everywhere, effectively killing all the germs and other microorganisms. Finally, the ultra-filtration (UF) technology uses threads of fibers in order to remove extra hardness from water. The process involves passing water through microfiber threads, thereby removing excess salts.
When to use RO+UV+UF water purifiers?
Choosing the most appropriate water purifier for your home or office is not as simple as it sounds. First of all, it is important to know what the TDS level of your water supply is. It means total dissolved solid, which water contains in the form of dissolved salts, impurities and heavy metals like lead, arsenic and mercury. TDS is essentially a measure of combined impurities. The TDS level of 50-150ppm is excellent, and above 1200 is just unacceptable. Therefore, RO+UV+UF water purifiers should be used when the water has high TDS levels (1000-2000ppm).
Moreover, rivers are the major source of water in Indian households and these are getting contaminated with each passing day due to factory-wastes and sewage disposals. These contaminants pose serious health issues in India like Cholera, Hepatitis, Jaundice, Typhoid etc. Water treatment plants must meet certain quality standards but despite that, many harmful bacteria and viruses slip through the cracks and contaminate the water supply to our homes.
The groundwater is also an important source of drinking water in our homes. It is also increasingly getting polluted because of the excessive use of pesticides (Endrin, Heptachlor, Lindane, and Pentachlorophenol), fertilizers (Urea and Sulfates) and Radio-nuclides (Radium, Uranium). It is also very hard due to the presence of unwanted heavy metallic compounds like, Fluorides, Arsenic, Mercury, and Lead. Because of all these factors, the water needs powerful RO+UV+UF purification.
The RO+UV+UF technology can even work with very muddy, dirty, and turbid water. The super treated RO+UV+UF filtered water has various industrial applications as well: boiler feed water for power generation, pharmaceutical, food & beverage, semiconductor, and metal finishing.
