Safe drinking water and more important prciplof water pufiHo
Water is the source of life. The quality of drinking water quality is closely related to peoples health. According to the World Health Organization (WHO) survey showed that 80 percent of the worlds disease and 50% of child deaths are related to poor water quality and drinking water. After many years of propaganda and popularization of drinking water and health knowledge, people have gradually understand the impact drinking water quality on human health. Therefore, water purification than other electrical home appliances, the development momentum can be described by leaps and bounds. But, you know exactly how much water purifier to purify the principle of it?
water purifier filter what you are? Household water purifier filter stages are generally 4 or 5 level filter filtration. Wherein a filter is also known as PP cotton, granular activated carbon of the second stage, the third stage is a precision compressed activated carbon, reverse osmosis membrane Zi four or ultrafiltration membrane, after five Zi activated carbon. If the filter is four, then the last layer to improve the taste or to the activated carbon filter may be omitted.
2, What is reverse osmosis?
reverse osmosis technology, is the most advanced and most energy efficient membrane separation technology. The principle is higher than the osmotic pressure of the action, based on other substances through the semipermeable membrane can not these substances and water separated. Since the reverse osmosis membrane pore size is very small (only about 1OA), it is possible to effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. (removal of up to 97% -98%). Reverse osmosis is a high water equipment most widely applied desalination technology, it is the object of separating the ions in solution and the molecular weight range of a few hundred organics; reverse osmosis (the RO), ultrafiltration (the UF), a microporous membrane filtration ( MF) and electrodialysis (EDI) techniques belong membrane separation technology.
3, filter replacement cycle is how long?
The water purification filter products of different raw materials used, the effects and the filter quality is different, a common barrier material is primarily adsorption and filtration functions, such as PP cotton filter and activated carbon filter. With the use of time, impurities in the water will clog the filter, activated carbon filter adsorption saturation will generally PP filter needs to be replaced three months, six months carbon filter needs to be replaced. Both filter can not effectively remove bacteria and organic contaminating microorganisms. After the failure of saturation is not easy to find.
a hollow fiber, nano-ceramics are purely physical barrier filtration. Their filtering accuracy can be reachedTo 0.1-0.01um, can effectively filter out bacteria and harmful substances, the use of two filter water filtration water purification products can be directly consumed. Since the hollow fiber can not be cleaned, it is generally placed at the rear end PP cotton and use of activated carbon, or relatively easily clogged, water purification equipment as a terminal sterilization using general 1--2 years needs to be replaced.
Because the use of nano-ceramic sintering natural diatomaceous earth, better filtration, 100% removal of bacteria and impurities. When too many impurities will decrease the water flow filter, easy to grasp cleaning time filter due to the high strength, can be repeated brushing using 50-100, and each cleaning effect of the filter cartridge can be seen, the best is the most security, use the longest direct drinking water filter products.
