PP Pleated Filter Cartridges can assist the water purifier to filter out more than 100 kinds of impurities in water, including some heavy metals in water, sediment and rust, residues of chemical fertilizers and pesticides, bacteria and viruses in water, etc., which are only a part of them. For more information about the PP Pleated Filter Cartridges, please read the following words.
What are the structural components of PP Pleated Filter Cartridges?
How do PP Pleated Filter Cartridges work in the filter cartridge shell?
What is the working process of the PP Pleated Filter Cartridges?
PP Pleated Filter Cartridges structure: filter cloth, filter screen, filter disc, sintered filter tube, wire wound filter element, meltblown filter element, etc. Due to the different filter materials, the filter pore size is also different. Precision filtration is a kind of filtration between sand filtration (coarse filtration) and ultrafiltration, and the filtration pore size is generally in the range of 0.5~120μm. The same form of filter material can be divided into different specifications according to the external size.
The filter cartridge shell is generally made of stainless steel, and the interior uses PP Pleated Filter Cartridges, wire wound, folded, titanium filter elements, activated carbon filter elements and other tubular filter elements as filter elements. Meet the water quality requirements. Under the action of pressure, the stock solution passes through the filter material, the filter residue remains on the tube wall, and the filtrate flows out through the filter material, so as to achieve the purpose of filtration.
The purpose of PP Pleated Filter Cartridges is to prevent the large particles in the water from entering the reverse osmosis membrane and ensure the normal operation of R0. The security filter is a vertical columnar device with a built-in PP spray filter with a filtration accuracy of 5μm. Colloidal and particulate fouling can seriously affect the performance of reverse osmosis components, such as greatly reducing water production and sometimes system salt rejection. The initial symptom of colloidal and particulate fouling is an increase in system pressure drop.
The sources of sludge and colloids in reverse osmosis feedwaters vary considerably and typically include corrosion products from bacteria, clay, colloidal silica, and iron. Pretreatment flocculants used in clarifiers or media filters, such as polyaluminum chloride, ferric chloride, cationic polyelectrolytes, will combine with tiny colloids and particles to aggregate into large-scale flocs, which are easy to be filled with media or filter elements. This type of flocculation reduces the pore size requirements for media filters and PP Pleated Filter Cartridges and still provides excellent filtration performance.
