Powder activated carbon (PAC) stands as a pivotal purification agent renowned for its exceptional adsorption capabilities, serving a myriad of applications across liquid and gas phases. As a counterpart to granular activated carbon (or GAC), powder activated carbon boasts distinctive properties and utilities, making it a cornerstone in various purification processes.
What is Powder Activated Carbon?
Powder activated carbon represents a finely ground form of activated carbon, characterised by its minute particle size. Typically, powder activated carbon particles measure below 0.2mm (200 microns), distinguishing them from the larger granules of granular activated carbon (GAC). This finely powdered state enhances its surface area, augmenting its adsorption efficiency and reaction kinetics, rendering it ideal for specific purification tasks.
Powder Activated Carbon Manufacture and Composition
Similar to granular activated carbon, powder activated carbon is crafted from premium-grade carbonaceous materials such as bituminous coal, coconut shells, or select wood types. These raw materials undergo a meticulous activation process, wherein they are subjected to high temperatures in a carefully controlled environment, resulting in the formation of a highly porous structure conducive to adsorption.
How Does Powder Activated Carbon Work?
The efficacy of powder activated carbon (PAC) lies in its high surface area and intricate pore structure, comprising microscopic voids and channels invisible to the naked eye. As the powder activated carbon interacts with a contaminated fluid, impurities are ensnared within these minuscule pores via a process known as adsorption. This mechanism facilitates the removal of a diverse array of contaminants, including odours, tastes, colours, heavy metals (e.g. mercury) and dissolved chemicals, thereby purifying the fluid stream.
Applications and Utilities
Powder activated carbon (PAC) finds extensive utility across an array of industries and purification processes, owing to its versatile adsorption properties. Common applications encompass the treatment of drinking water, wastewater remediation, groundwater treatment, liquid chemicals and gas-phase purification tasks, particularly the removal of mercury, dioxins and furans in flue gas treatment systems at energy-from waste facilities. Indeed, the treatment of flue gas streams with powder activated carbon has been identified in the recent EU BREF as the Best Available Technique for the removal of mercury and VOCs at EfW facilities, and Puragen is a leading supplier of powder activated carbon for this application.
Advantages and Disadvantages of Powder Activated Carbon
The fine particle size of powder activated carbon facilitates rapid adsorption kinetics, ensuring swift and efficient contaminant removal. Powder activated carbon is different from granular activated carbon in that cannot be used in mobile carbon filters. It is designed for single-use only, meaning powder activated carbon is not a sustainable option as it cannot be recycled via thermal reactivation, unlike granular activated carbons (GAC).
