KNL PRO NF20 AR Blue NF (Nano Filtration) water purifier with SS 304 UV, with Alkaline regulator, for input TDS up to 200 ppm, Reduces TDS (15-25)%, no TDS controller, tank 10 liters + TDS meter

Features

• Water purifier cabinet & Accessories ABS/Food grade material including all spares, wall mount/table top, storage (transparent black) 10 liters, transparent black storage tank 10 ltrs., with three separate white led indicators, insects proof, strong and super finished built quality. Easy to clean storage tank, operate and maintain, 6 filters rear side space.
• Stage 1 & 2. Pre Filter (Common in each case) [Fitted with polypropylene (PP) Spun 10", pore size 5 micron] Captures all particles larger than 5 microns (clay, sand, rust, colour, heavy metal etc.). Sediment Filter (Common in each case) [absolute 5 microns] The filter captures suspended particles such as sand, silt, loose scale, clay and organic material then goes to activated block carbon filter.
• Stage 3. Activated Carbon Block Filter (Common in each case) [1000 IV] Made from activated carbon in solid cylindrical block, absorbs harmful chemicals, toxic substances, iodine, chlorine etc., removes odor, and enhances water taste. We the KNL uses only activated block carbon over charcoal granules. As the granules performance is very less compare to block carbon.
• Stage 4. KNL NF20 Membrane. BARC licensed, 100 GPD, pore size 0.0015 microns. The membrane reduces TDS around 20% with variation of ( 5%) from feed water and maintain all essential minerals around 80% with variation of ( 5%) in drinking water naturally. Flux rates around 35 liters per hour. The membranes remove arsenic, mercury, lead, cyanide, bromide, pesticides, herbicides, VOCs, bacteria, protozoa, viruses, germs, microbes, color, smell and all other contaminants from feed water and flushes them through rejected water. The UV cannot eliminate these impurities and TDS controller allows these impurities back in your drinking water.
• Stage 5. Activated Post Carbon (common in each case) [Coconut shell] the post carbon, half part is filled with coconut granules & half part is inbuilt UF filter. Coconut granules is antibacterial agents and therefore inhibits the bacterial growth and enhances drinking water taste.
• Stage 6 - AAA Filter - [PH Cartridge] the filter is used to enhance pH of membrane treated water. The filter adds up to pH 3.0 and a little necessary minerals too. The pH cartridge contains different kind of ceramic balls (basically natural stones) and coconut shell charcoal granules. These stones are enriched with essential minerals and contains high pH value too. Therefore when water passes through the cartridge, the pH getting enhanced. There is no chemical but all are natural. We use regulator here to achieve range between pH 7.5 to pH 8.2 which is ideal and best. Acceptable range is pH 6.5 to max pH 8.5.
• Stage 7 - SS 304 UV Chamber. Steel does not react with water but aluminium leaches aluminium oxide which contaminates drinking water. Aluminium oxide causes brain related health problem in a long run. The UV lamp emits radiation that kill the germs of the water. The NF/RO membrane is sufficient enough and does the job, however, UV is added for further peace of mind.
