What does Polypropylene (PP) filter cartridge do in water filtration?

The function of cartridge filter is to separate substance or particle from liquid. Cartridge filter is a media to filtrate substance that flow with liquid. Cartridge filter in this project focus for water filtration system that usually used at houses and small scale industry. Volume flow rate relate with pressure of the water that flow through pipe system. Cartridge filter 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 cartridge filter. Sediment sand make contact on the surface of cartridge filter depend on the volume flow rate of water. Cartridge will clogged because of sediment sand clog on the surface of cartridge filter when tried to enter the cartridge filter. This situation make filtration system has different pressure on the entrance and the exit of cartridge housing. Different pressure call pressure drop represent the pressure drop of the cartridge. From the pressure drop can relate with volume flow rate and determined life span and maximum condition of the cartridge filter. Maximum clogging condition happen because of pressure of cartridge filter does not increase anymore and cartridge filter has fully clogged with sediment sand.

What do carbon filters remove from water?

Water purification removes harmful contaminants from water. Filtration, which physically blocks or chemically removes contaminants, is a different purification technique from reverse osmosis, which filters water through a semi-permeable membrane, and distillation, which vaporizes water to separate it from the contaminants. Carbon filtration is a relatively cheap and efficient way of to purify water.

How Carbon Filters Work

Carbon filters work so well because of their large surface area. According to the Home Water Purifiers and Filters website, one pound of carbon has a surface area of approximately 125 acres. This allows carbon to physically absorb a large amount of chemicals and substances that pose serious dangers to the normal domestic water supply. Many of these substances can cause cancer, neurological problems and other health risks if ingested in large quantities.

Types of Carbon Filters

There are generally two types of carbon filtration: granular activated carbon and block carbon. Activated carbon has a slightly positive charge so it can attract impurities, but block carbon has a higher contaminant removal ratio. However, there are many factors that affect this rate, including the amount of carbon in the unit, the flow of water, the length of time contaminants spend in contact with the carbon and the particle size. Carbon can remove particles 50 micrometers to 0.5 micrometers in size.

What Carbon Filters Remove

Carbon filters are very effective at removing a number of deleterious chemicals, reports the Home Water Purifiers and Filters site. These include chlorine, benzene, radon, solvents trihalomethane compounds, volatile organic chemicals such as pesticides and herbicides and hundreds of other man-made chemicals that may come into contact with tap water as it proceeds through the system. In addition, filters remove bad tastes and odors from the water.

What Carbon Filters Don't Remove

Carbon filters are not particularly successful at removing dissolved inorganic contaminants and heavy metals such as minerals, salts, antimony, arsenic, asbestos, barium, beryllium, cadmium, chromium, copper, fluoride, mercury, nickel, nitrates, selenium, sulfate, thallium and other contaminants, which may require a reverse osmosis system or distiller instead. Carbon block filters can remove some large, dangerous microorganisms, such as giardia and cryptosporidium, that can cause a number of diseases and epidemics, but nothing less than the size of the carbon itself. Viruses are too small to be removed by carbon, as they usually range between 20 and 400 nanometers in size, according to the University of Oregon.

Considerations

Carbon filters are even more effective if you ad physical or chemical absorption to the mix. Iron, manganese and hydrogen sulfide can be removed by high quality carbon filters, but a manganese iron reduction filter is generally more effective at removing these particles, especially at higher concentrations. A sediment pre-filter is better at removing sediment and particulate material, and extends the life of the carbon filter by preventing clogs, according to Home Water Purifiers and Filters.
