Sediment PP cartridges are the basic filters which can remove small particle such as sand, mud, asbestos, silt, and turbidity from the water. They are made from melt brown PP fibers.
Normally speaking, sediment PP cartridges are used to remove all types of sedimentary particles as per the required micron rating. PP pore sizes are divided to 1 micron, 5 micron, 10 micron and 20 micron.
These materials are cheaper compared to the materials used with other cartridges and it is where sediment PP cartridges got its other name of low-cost infiltration cartridges. Also, PP cartridges prevent pressure difference during the filtration. These materials are rather preservative, safe, and inexpensive and have good filtering rates. Sediments PP cartridges are equipped for the first stage cartridge in water filters and RO systems.
There are three types of PP cartridges which are melt blown, wound filter and pleated filter. Although the melt blown cartridges’ filtering rate and service life are lower compared to other PP filters and it is the cheapest one among their kinds. Melt blown filter is also the standard one in water filters in the market.
On the contrary, the pleated filter has the best filtering rate but has the most expensive price. Furthermore, the wound filter has both high quality filtering rate and competitive price.
In addition, it is recommended to replace the PP cartridges once in 2-3 months. After using these materials for 2-3 months, you could find them discolor due to the sediments and rust. Although PP’s price is quite affordable, people should be avoided purchasing bad quality products.
If the production process is poor, this would cause the pore size too big. Plus, poor production would lead the PP to deform once contacting with high water pressure. Above situations would certainly affect the filtering rate. At result, the sediments might flow to the following filters and result in clogging.
It is suggested that you press the sediments PP cartridges to check if it is firm before purchasing. Also, you could buy from ALYA which has released high quality filtering materials to bring you clean and safe pure water.
