Powdered Activated Carbon
Powdered activated carbons (PAC) are defined by the ASTM as particles passing through an 80-mesh sieve (0.177 mm) and smaller. Hytech Carbons manufactures many types of powdered activated carbon products, each specifically engineered to provide a unique pore structure and adsorption properties. By varying manufacturing conditions, internal pore structures are created by imparting unique adsorption properties specific to each product type. The choice of product for a specific application will vary due to differing impurities and proprietary process conditions.
The adsorptive capacity of Hytech Carbon’s powdered activated carbon (PAC) makes it ideal for removing a variety of contaminants from water, air, liquids and gases.
