With people's attention to the quality of drinking water, water purification system began to enter thousands of households. The filter element of different water purification equipment is different, and the filtration effect is different. Know filter <a href="https://www.lyfilter.com/customized-polypropylene-pp-melt-blown-filter-cartridge" rel="noopener noreferrer" target="_blank"><a href="https://www.lyfilter.com/customized-polypropylene-pp-melt-blown-filter-cartridge" target="_blank">PP fiber filter element</a></a> Function: The melt-blown filter core is made of polypropylene micro-fiber hot-melt entangle, the fiber randomly forms three-dimensional micro-pore structure in space, and the pore size is gradient distribution along the filtrate flow direction. It integrates surface, deep and fine filtration into one, and can hold back impurities of different particle size, remove suspended matter in water, sediment, rust, etc. The filtration accuracy is 1μm. Application: used for primary filtration of groundwater/surface water, pre-filtration of water purifier, used as the primary filter element of water purification equipment. Activated carbon filter element Function: The main function is adsorption, generally speaking, the larger the surface area of carbon particles, the stronger the adsorption, the higher the filtration accuracy, the better the filtration effect. In water treatment can be used to remove residual chlorine, organic matter, heterochromic, peculiar smell and part of heavy metal ions in water. Purpose: pre-activated carbon adsorption organic matter, residual chlorine, heavy metals, etc., activated carbon after adjusting PH value to change the taste of water. KDF(copper, zinc alloy) filter element Function: Remove chlorine and heavy metals from water by electrochemical REDOX (electron transfer), and prevent bacterial growth. Application: Mixed with activated carbon for filter element, increase the life of activated carbon. Resin filter Function: soften hard water by ion exchange and remove calcium and magnesium ions. Application: household soft water, reverse osmosis pre-treatment, etc. Microfiltration (MF) -- ceramic filter element Function: Ceramic filter element is sintered from natural diatomite, there are numerous small holes in the internal gap, the porosity is as high as 80-90%, the pore size of the filter element is less than 0.2μm. Filter out suspended solids, microorganisms, bacteria, rust, etc. Ultrafiltration membrane (UF) Function: bacteria and colloid, rust, suspended matter, sediment, macromolecular organic matter which are much larger than bacteria can be trapped by ultrafiltration membrane, generally used in the third stage of water purifier. The filtration accuracy is up to 0.01μm. Nanofiltration membrane (NF) Function: Nanofiltration membrane is a functional semi-permeable membrane that allows the penetration of solvent molecules or some low molecular weight solutes or low ion. So named because the size of the material that can be trapped is about nanometers. The filtration accuracy can reach 0.001μm. <a href="https://www.lyfilter.com/ro-plant-20-30inch-1um-3um-high-flow-filter-cartridges" rel="noopener noreferrer" target="_blank"><a href="https://www.lyfilter.com/ro-plant-20-30inch-1um-3um-high-flow-filter-cartridges" target="_blank">Reverse osmosis membrane (RO)</a></a> Function: The pore size of RO membrane is five parts per million of a human hair, and bacteria and viruses are 5,000 times larger than it. Therefore, only water molecules and some mineral ions can pass through. Filtering accuracy up to 0.0001μm. When should the filter element be replaced? The obvious decrease of the water flow indicates that the filter element is blocked. The filter element should be cleaned in order to restore the normal flow. After cleaning, the flow is still very small, and it is necessary to replace the new filter element for the water purifier. The taste of the effluent drops and is close to that of the tap water. The residual chlorine taste of the tap water cannot be removed, indicating that the activated carbon filter is saturated with adsorption and the activated carbon is invalid. Generally speaking, the filter element has a replacement cycle, but the specific filter element replacement time varies according to the water quality of the user and the net amount of water used. How long is the replacement cycle of <a href="https://www.lyfilter.com/products" rel="noopener noreferrer" target="_blank">filter element</a>? PP filter element is commonly used as the primary filtration of various household water purification equipment, mainly for the pretreatment of tap water and the role of ultrafiltration (or RO) membrane protection. The filter element is easy to be blocked and needs to be replaced frequently. The general replacement cycle is 3 to 6 months. Activated carbon filter can effectively remove the residual chlorine in the water, odor, heterochromatic, etc., but also can effectively adsorb some organic macromolecules in the water, can change the taste of water, the general replacement cycle of 3 to 6 months. The purification principle of ceramic filter is similar to that of activated carbon, but the filtration effect is relatively good and the life is relatively long. The filter slag of the filter element is hidden in the yarn, which needs to be rinsed with a brush and polished with sandpaper. The general replacement cycle in half a year to a year. Ion exchange resin filter core can ion exchange with calcium, magnesium and other cations in water and anion sulfate radical, to achieve hard water softening and deion, the general replacement cycle in half a year. The water purified by reverse osmosis filter can be directly drunk, but because the pore size of reverse osmosis membrane is very small, it is easy to be blocked by impurities and lose its function. In order to extend the service life of RO membrane, pp cotton, activated carbon and other filter pretreatment should be carried out. RO membrane is generally used in the fourth stage. The general replacement cycle is one to two years. Ultrafiltration membrane filter core long service life, filtered water can be raw drink, large water output, no need to add electricity, pressure, low purification cost, can be repeatedly rinsed recycling use. The general replacement cycle is 10-12 months. After grasping the functional characteristics and replacement cycle of different filter elements, the filter elements of household water purifier can be better protected and the service life of water purifier can be extended.
