RO(Reverse Osmosis) water purification systems waste a large portion of the water that runs through its system. More than 80% of water is rejected or wasted in a household RO system leaving only 20% or less for consumption.
Using a RO water purifier for low TDS input water, say less than 200 ppm, may be detrimental to your health in the long run, as the water is stripped of essential minerals and salts.
UV water purifier kills bacteria and viruses but does not remove dissolved impurities such as pesticides, rust, arsenic, fluoride etc. It does not convert hard water to sweet, soft water.
There are two terms commonly associated with UV water filtration systems: dosage and UVT. Dosage refers to the amount of ultraviolet energy needed to destroy contaminants and micro-organisms in the water. According to industry standard, a frequency of 254 nanometers is used to achieve disinfection. UVT, ultraviolet transmittance, is often used when discussing the amount of UV light needed to penetrate water flow.
•No need to handle potentially dangerous chemicals (chlorine)
•Virtually immediate disinfection (no contact tanks like chlorine)
•Low power consumption Environmentally friendly (no disinfection by-products)
•No moving parts to wear out or replace UV does not change the taste or odour of the water
•Lower equipment investment verses other disinfection options Simple maintenance (with proper pre-treatment).
•Chemical vs. Physical Disinfection of Contaminated Water
