What is Activated Carbon Filter?
Activated Carbon Filter is widely accepted system in water filtration techniques. The treated water is free from chloramines (chlorine and ammonia mixture) and organic compounds; therefore, best for discharge and production use. Activated Carbon Filter is also utilized in pre-treatment for ro water plant and dm plant as the treated water keeps these systems safe from oxidation or organic fouling.polyacrylamide
Activated Carbon Filter Working Principle
An activated carbon filter (ACF) works on the principle of adsorption; filter medium adsorbs or reacts with a pollutant molecules then filtered water is drained out. Activated carbon which is used as medium to remove contaminants is natural material derived from coconut shell, lignite, bituminous coal etc. further, activated by chemical or steam under absence of oxygen with high temperature around 1000°C. Specific contaminants can be removed by employing blends of various carbons.
Limitations of Activated Carbon Filter
There are some limitations of activated carbon filters (ACF); uses are limited to wastes with low organic concentrations (< 5%) and very low inorganic concentrations (< 1%). Removing highly soluble organics or those with low molecular weights are also out of their capabilities. An activated carbon filtration system is unable to remove all of contaminants; such as, microbes, sodium, fluoride and hardness from water; however, special activated carbon water treatment is necessary for removing lead and other heavy metals. In addition, disposal process of contaminated carbon is complicated if not regenerated.
Which Activated Carbon is Right For You?
There are two types of activated carbons available, Granules Activated Carbon (GAC) and Powdered Activated Carbon (PAC); choosing which one is best suitable for your application is not a difficult task. In general, Granule Activated Carbon is made by steam activation of coal and is widely used in purifying drinking water, whereas Powdered Activated Carbon is produced by steam activation of lignite coal under carefully controlled conditions and is used in treating (remove toxic organics along with BOD, COD and TOC) industrial wastewater, process water and highly contaminated municipal wastewater.buy polyacrylamide water treatment
