Open flow UV+UF water purifier, it's on open ss high quality stand without tank storage. you can use it with any other storage, water cooler, tank etc. This purifier is most usable for area where TDS below 500 ppm( as per WTO guideline 500 ppm TDS water is drinkable for human health). this filter is very effective in rain water because rain water TDS around 200 ppm only, but due to dirt, dust, soil, organic, inorganic content, Bactria, virus etc. include in this water so this water is not suitable for drinking. this filter removes all impurities and give a pure water for drinking. Procedure of water filtration:- 1. PP Spun:- 5 micron spun remove, dust, dirt and soil particle from water. 2. A filter with granular activated carbon (GAC) is a proven option to remove certain chemicals, particularly organic chemicals, from water. GAC filters also can be used to remove chemicals that give objectionable odors or tastes to water such as hydrogen sulfide (rotten eggs odor) or chlorine. 3. CTO:- cartridges, are made with coconut shell based carbon which creates what many believed to be sweeter tasting water. The unique structure of this carbon is well suited for chemical adsorption, including VOCs, while reducing chlorine and chemicals that contribute to taste and odor. Polypropylene non-woven pre-filtration media and will operate effectively in most installations without pre-filtration. 4. Philips UV:- Ultraviolet water purification is the most effective method for disinfecting bacteria from the water. Ultraviolet (UV) rays penetrate harmful pathogens in your home’s water and destroy illness-causing microorganisms by attacking their genetic core (DNA). This is extremely efficient in eliminating their ability to reproduce. UV systems destroy 99.99% of harmful microorganisms without adding chemicals or changing your water’s taste or odor. 5. UF:- Ultra Filtration Membrane that can remove up to 99.99% of microbial pathogens and filter out undissolved impurities. The UF membrane has a filtration fineness of 0.1 micron.which allows water to pass through the blocking microbial pathogens and contaminants.
