Walnut Shell Activated Carbon
What Is Walnut Shell Activated Carbon?
Walnut Husk Active Carbon is a strong, natural, active carbon that comes from the tough outer skin of walnuts – a rich farm by-product that comes from the processing of nuts in the food-and-oil-extracting sector. The production process starts with a controlled carbonation of the purified walnut husk at elevated temperatures and then the formation of a highly porous interior structure that is optimized for absorption.
Walnut shell is one of the toughest and most structurally flexible nut shell raw materials used in active carbon production. Due to its unique physical composition, it has a balanced meso- and micro-pore distribution, providing versatile adsorption capacity across both liquid and gas phase applications. This wider pore profile – as opposed to the pure micropore structure of coir or almond – allows PAC to be particularly efficient at catching bigger organic molecules, suspended solids, and oil pollutants. Coupled with its extraordinary hardness and wear resistant properties, it has been a candidate for filtering systems that require both cleaning accuracy and mechanical durability.
Why Choose Walnut Shell Activated Carbon?
- Outstanding Hardness and Abrasion Resistance — The inherent density of the Walnut casing results in an active carbon with industry leading hardness values that minimise the deterioration of the particles, the formation of the fine, and the loss of the medium in the high flow or the back of the filter system.
- Balanced Meso- and Micropore Distribution — Different from the strict micro-porous carbon, the wider pore profile of the PECC allows efficient absorption of low and middle molecular mass pollutants, thus broadening the scope for efficient use.
- Superior Performance in Oil and Grease Removal — The Mesoporous Structure is especially suited to the removal of hydrocarbons, oil residues, and nonpolar organic matter from the industrial waste water and the generated water flow.
- Excellent Backwash and Regeneration Stability — Walnut Casing Carbon has a strong mechanical tenacity that enables it to endure multiple back cleaning cycles with no major degradation in the medium, thus increasing the lifetime of the product and lowering the overall filter system cost.
- Versatile Across Industries — From urban wastewater treatment and waste disposal to the production of water-treated products in the field of petroleum and natural gas production, CPAC provides uniform performance over a broad range of challenging circumstances.
Industry Challenges About Walnut Shell Activated Carbon
Seasonal Raw Material Availability
The fact that the supply of walnut shells is linked to the year’s crop cycle and is concentrated in a particular area of production, may result in a lack of consistency in the procurement process and a delay in the delivery of large quantities.
Higher Cost vs. Coal-Based Carbon
Competition from Coconut Shell Carbon
Batch-to-Batch Variability
Limited Mesopore Development
Why Use Our Walnut Shell Activated Carbon
High Adsorption Capacity
Generally 900-1100 meters per gram of BET, it is effective in eliminating chlorine, organic pollutants, VOCs, colours, and smells in the air and water flow in a consistent, quantifiable manner.
Superior Mechanical Strength
The naturally dense, fibrous structure of almond shells produces a hard, abrasion-resistant carbon with low dust generation — ensuring longer service life and reduced replacement frequency in filtration systems.
Outstanding Backwash Durability
It is highly dense and structurally complete so that it can endure multiple backwashing cycles with no major break-down – keeping the bed performance and minimizing the loss of the media in the PWR.
