People widely use chemical filter in water filtration. About Chemical filters working principle or chemical filters working condition, there are different ways to "chemically" treat the water including ion exchange, adsorption, chemical bonding, and molecular destruction. Also you can use many different media in the chemical filter and in different applications. These applications include zeolite, peat moss, calcium hydroxide, poly adsorption pads and other chemically treated media. Among them, one types of widely used chemical filter is carbon filter. The carbon filter working principle is what we mainly talk about here.
As one type of chemical filter, carbon filter is used known as activated carbon. In order to know the chemical filters working principle, you have to know the activated carbon at first. Activated carbon is a kind of carbon dealt to have small, low-volume blowholes that improve the surface area available for adsorption or chemical reactions. Because of its high level of micro porosity, just one gram of activated carbon has a surface area beyond 500 m2 as Wikipedia said. Activated carbon is widely used in gas purification, gold purification, metal extraction, water purification, medicine, sewage treatment. Activated Carbon Filters quality changes hugely.
About the chemical filters working principle, the activated carbon in the surface of the motes shapes into a layer of balance surface thickness and then absorbs the organic material into active carbon, which can make sure its high adsorption effect at the early stage. But the active carbon adsorption ability will ease off finally, as well as the adsorption effect. There are several factors affect the effectiveness of activated charcoal. The pore size and distribution varies based on the source of the carbon and the manufacturing process. Large organic particles are taken in better than smaller ones. Adsorption tends to improve as pH and temperature reduce. Contaminants are also deleted more effectively if they keep in touch with the activated charcoal for a longer time, so flow rate through the charcoal has impacts on filtration. If the water quality in aquicolous box is cloudy and the organic matter content in water is high, activated carbon will soon waste filter function. So, we should regularly clean or replace activated carbon. The main function of activated carbon filter is withdrawing macromolecular organic matters, iron oxide and residual chlorine. It is easy for organic matter, residual chlorine and iron oxide to make ion exchange resin poisoning.
After learning chemical Filters working condition and principle, you must have understood chemical filters well. For more information about chemical filters working condition, please visit the website through the link with www.hefilter.com.
