Powdered Activated Carbon
Classification Introduction
Product Advantages and Characteristics
- Rapid adsorption kinetics: The small particle size means a short diffusion path, so that such materials can take up contaminants in the liquid much more quickly and respond fast to moving process conditions.
- Extremely high surface area: Many process conditions may be encountered wherein it is essential that contaminants in the liquid may be adsorbed by the largest surface area possible (e.g. many impurities, organic matter, Colouring dyes; their wetted surfaces will offer the largest contact area per unit volume of impurity to the adsorbing materials being used).
- Greater flexibility of usage and control: These materials can be readily dosed into almost any stream (reactors, mixing, treatment tanks, etc.) as a slurry, and the treatment can be so easily controlled from hour to hour etc.
- Economy in batch treatments: The treatment of certain specific batches would otherwise be costly if fixed-beds have to be provided for and such type of batch treatment would exceed the cost of fixed bed.
