For more than 90 years, powdered activated carbons have been used to purify a multitude of food items, water and chemicals. The many uses include public as well as point-of-use water treatment methods, catalysis, as well as de-colorization, deodorization together with toxin removal in chemical compounds, pharmaceutical products, food items and drinks.
When looking at liquid-phase filtration in batch and ongoing dosage applications, powdered activated carbon continues to be the first choice of many. Its controlled particle size generates a mixture of quick kinetics, substantial volume, great settling as well as suspension qualities and low-pressure filtration.
Easily obtainable in an assortment of grades, powdered activated carbons handle many different pore measurement distributions, surface area chemistry and purity degrees. Created by direct activation, powdered activated carbons have been expressly designed for removing an extensive array of natural and organic pollutants from drinkable, waste, and process water.
Medical and Emergency Applications
Powdered Activated Carbon has additionally played an essential role in medical care along with being an air and water purifier. The earliest recorded date of use was in 1550 BC as an antidote to poison — it is just as effective today and is a staple of emergency rooms worldwide.
Drinking Water Purification
Activated carbon is a key element for making drinking water safe. Drinking water filter systems — typically made up of activated carbon — are designed to remove oxidation, sediments, and natural and organic materials which add flavor, smell or coloring, such as chlorine and other chemical compounds.
Powdered activated carbon is a fairly small particle in size in comparison with granular activated carbons and as a result provides a sizable surface area to volume ratio. This means it is an excellent choice for removing toxins and organic material from waste water for a wide variety of industries.
Industrial Applications
In industrial settings, PAC is used in batch dosing processes where it is added directly to liquids, allowed to adsorb contaminants, and then filtered out along with its adsorbed load. This makes it particularly versatile for applications ranging from sugar decolorization to pharmaceutical API purification to effluent treatment.
