Aluminum profile processing and cleaning water filtration
Working Principle
The most practical, cheapest and basic type of water filtration is a carbon filter to clean water. Carbon filters have a multitude of applications including filtering drinking water and keeping a fish aquarium’s water from getting murky. While it can remove some particles that cloud the water, reduce nasty chlorine residue and can even help to reduce odors, thus improving the general taste and clarity of water, it does have its limitations when it comes to microbe and bacterial removal.
In the process of filtering water, activated carbon is often used to remove contaminants and impurities. Carbon is probably the most absorbent material known to man, and it is uniquely efficient because of thousands of tiny pores that can absorb. For example, a pound of activated carbon provides 125 acres of filtering surface area. The carbon is positively charged to attract negatively charged impurities such as chlorine, chemicals and volatile organic compounds.
Most carbon water filters are either made with granular activated carbon (GAC), or powdered block carbon material. Those with carbon block are the most effective, since there is a larger ratio of activated carbon surface area to water, and also because the powdered block form is denser and water travels through it more slowly. The larger surface area created by the block carbon, and the more time the water is in contact with the carbon, the more contaminants are removed.
The active carbon filter
- High efficiency;lower operating expense;lower maintaining charges;lower one-time investment;lower head loss;lower requirement for inflow water quality;stable effluent quality;brilliant filtration,easy to reorganize & expand,smaller land covering,good appearance
- The residual clorine in the water after being filtered by active carbon filter is no more than 0.1PPM
- The performance to remove the odar,organics,colloid,iron and residual clorine is outstanding;
- It’s conductive to lower the turbidity,chroma,water quality purification and to reduce the pollution to follow-up systems
