How many levels of purifier of filter water?
4, RO reverse osmosis pure water machine is the best water purification product to treat the water effect of rural water and ground water. It has three stage pre filtration, one stage reverse osmosis membrane, precise filtration and one stage post filtration. The filtered water is free of bacteria, viruses, heavy metals, pesticides, organic matter, minerals, and distinctive odor. It is a pure water, which can be drunk without heating. This kind of reverse osmosis pure water machine belongs to the top-grade water purification product, each price is between 1000 yuan and 5000 yuan.
2 、 multistage filter water purifier. The water purifier has two stages of coarse filtration and a set of fine filtration, and the fine filtration adopts a hollow fiber filter element, and the filtered water can be directly drunk. Multi stage filter water purifier belongs to the mid-range water purification product, each price is between 300 yuan and 500 yuan, which can be accepted by the working class, and the family use more.3, UF ultrafiltration nanofiltration membrane water purifier, multi-stage pre filtration and ultrafiltration, the vast majority of bacteria, which can remove harmful substances, is the most commonly used separation, filtering effect is one of the most common direct drinking water purifying device, while retaining beneficial minerals and trace elements, and then take advantage of KDF and activated carbon can effectively inhibit the bacteria in the water, fungi breeding and the removal of color, smell, to ensure that the use of filtered water more safety and health. Moreover, the production of water is relatively large, and the waste water discharge is small, so that it is more convenient and convenient to use in the kitchen of the family, and it does not need to wait for a long time. Belong to popular consumer goods, according to different requirements, each price range from 200 yuan to 5000 yuan.
Floating water purifier is the function of filter water, heavy metals, bacteria and viruses are removed, it has higher filtering technology, usually five filters, the first stage is also known as the second grade PP cotton filter, granular activated carbon, the third level for the precision compression of activated carbon, the four level for reverse osmosis the membrane or ultrafiltration membrane, the five grade activated carbon. Mainly used to improve taste1, the water purifier structure is different, the water purification effect is also different. Generally speaking, the primary filter water purifier has simple structure, mainly activated carbon, and its filtration capacity is limited. It can only be used as coarse filtration. The filtered water is best boiled and boiled. Most of the water filters with primary filtration are of low grade water purification products, and each price ranges from 10 to 150 yuan.
Water purifier according to different purification principle and process, can be divided into many kinds. General RO (reverse osmosis filtration precision in 0.00001 micron), nanofiltration (0.001-0.00001 microns filtration) ultrafiltration membrane (filtration accuracy of 0.01-0.001 microns), fine filter (filter accuracy of 0.01 microns or less, such as ceramic filter, PP cotton filter etc.).
