With the improvement of living standards, more and more people pay attention to the health of their drinking water, so many people like to install a water purifier on the water pipes of their homes during the renovation time to ensure the health of their drinking water, hard water The problem can be said to be a problem that plagues the entire water purification industry. The hard water we often drink is a limestone containing a large amount of alkaline substances, a bicarbonate content greater than 100mg/L (CaCO3), and a hardness greater than 150mg/L (CaCO3). of water. Because such water does not contain a large amount of calcium and magnesium particles, although hard water does not directly cause harm to the human body, it will bring a lot of inconvenience to our lives, such as scale. Hard water is usually invisible to the naked eye, and we only know it when we drink it. The harder the water, the more inconvenience it causes to our lives. Therefore, if you want to turn your drinking water into soft water, you must be able to go through a series of methods, and some of the current water purifier products have this function, which can Soften hard water and turn it into clean water suitable for drinking. There are many kinds of filter elements in water purifiers. There are two categories: compressed activated carbon filter, bulk activated carbon filter. 1. Compressed activated carbon filter element adopts coal-based activated carbon with high adsorption value and coconut shell activated carbon as filter material, and is sintered and compressed with food-grade binder. The inside and outside of the compressed activated carbon filter element is wrapped with a layer of non-woven fabric with filtering effect, to ensure that the carbon core itself will not drop carbon powder. Both ends of the carbon core are equipped with soft nitrile rubber gaskets, so that the carbon core can be loaded into the filter cartridge. Has good sealing. 2. Bulk type activated carbon filter packs the required activated carbon particles into a special plastic shell, and welds the end caps on both ends of the shell with welding equipment. Filter, pp filter manufacturer ensures that the carbon core will not drop carbon powder and black water when it is in use. According to the needs of customers, the shell end cover can be made into different types of connection ports. Interface methods are: flat pressure type, pipeline type. 2. PP filter element PP filter element is also called PP melt-blown filter element. The melt-blown filter element is made of polypropylene ultrafine fibers by thermal fusion entanglement. The fibers randomly form a three-dimensional microporous structure in space. It integrates surface, deep and fine filtration, and can retain impurities of different particle sizes. The filter element has a precision range of 0.5-100μm, and its flux is more than 1.5 times that of the same precision peak room filter element. Different types of end cap joints can be configured to meet the needs of various engineering installations. 3. Ceramic filter element The ceramic filter element is a new type of environmental protection filter element, which is prepared by using diatomite mud as raw material and using a special technology molding method. Its average pore size is only 0.1μm, which is the filter element with the current filtration precision. At present, Katadyn in Switzerland mainly adopts this water purifier filter element technology. The purpose of the ceramic filter element is to remove the liquid medicine, plating solution and solid particles in the tap water in the water, and the carbon filter element removes the organic impurities in the liquid. During filtration, the solution is pushed by the pump and flows through the filter cartridge and the filter element, and the particles are isolated in the filter element, and the filtered solution is returned to the electroplating tank or solution tank through the core tube. It is true that the filter paper can also filter out particles, but the function is different from that of the filter element. The filter paper relies on the surface to isolate the particles, while the filter residue of the filter element is hidden between the yarns, and its surface area is much larger than that of the filter paper. 4. Resin filter element Resin preferentially binds cations with strong charges, and the charge of calcium and magnesium ions is stronger than that of sodium ions. The displacing sodium cations then pass down the resin bed and out of the softener, so that the softener sends out soft water. Finally, all resin exchange sites are occupied by calcium and magnesium, and no work can be done anymore.
Professional water filter cartridges also understand that when you're working with water filters product, it's important to understand that quality of water filter cartridges supplier always matters.
As manufacturers we are determined to be the very best in water filter cartridges supplier, regardless of the size, pedigree or inclinations of our competitors.
Though the cost of these sustainability initiatives as water filter cartridges supplier can be high, harnessing the power of an ethical supply chain to appeal to conscientious consumers can be a smart move both ethically and financially.
