Most water purifiers use a polypropylene sediment removal filter cartridge for the first stage of the filter element.

The first stage of the filter element is not only directly affects the water quality but also affects the subsequent secondary or tertiary filtration effect and the life of the filter element. Therefore, the quality of the PP filter is especially important for water purifiers.

If the RO system is not equipped with a polypropylene sediment removal filter, the raw water directly enters the RO membrane.

Excessive particles, precipitates, microorganisms, and bacterial viruses that are not treated will block in the RO membrane, and the life of the RO membrane will be shortened, which will also affect the quality of the final water.

The function of the polypropylene sediment removal filter cartridge filter is to separate substances or particles from the liquid.

The cartridge filter is a medium to filtrate a substance that flows with liquid. Cartridge filter in this project focuses on a water filtration system that usually used at houses and small-scale industries. The volume flow rate relates to the pressure of the water that flows through the pipe system.

Cartridge filters function as a media that reduced pressure from the water flow and call pressure drop. Sediment sand particles function as particles that flow with the water and will filtrate with a cartridge filter. Sediment sand makes contact on the surface of the cartridge filter depend on the volume flow rate of water.

This situation makes the filtration system has different pressure on the entrance and the exit of the cartridge housing. Different pressure call pressure drop represents the pressure drop of the cartridge.

The pressure drop can relate to the volume flow rate and determining the life span and maximum condition of the cartridge filter.
