In the competitive landscape of industrial water treatment, the efficacy of your filtration system hinges on the raw materials you select. Our premium bulk activated charcoal for water filters is engineered to meet the rigorous demands of municipal, commercial, and industrial filtration projects. Sourced from select raw materials and processed through advanced activation techniques, this media offers a superior solution for removing contaminants, improving taste, and ensuring water safety. This page provides a comprehensive technical overview for procurement managers and water treatment engineers seeking reliable, high-volume filtration media.
Our bulk activated charcoal for water filters is a high-porosity, adsorptive media produced from select grades of bituminous coal, coconut shells, or wood. Through a controlled thermal or chemical activation process, we develop a vast network of internal pores, creating a material with an exceptionally high surface area. This structure physically and chemically binds with a wide range of organic compounds, chlorine, and volatile organic chemicals (VOCs). Available in granular (GAC), powdered (PAC), and extruded pellet (EAC) forms, this media is the industry standard for deep-bed filtration, point-of-entry systems, and high-flow industrial applications. Each batch is processed to ensure uniform particle size, minimal dust, and consistent adsorption kinetics.
The following table outlines the standard specifications for our most common granular activated carbon (GAC) grade. Custom specifications (e.g., iodine number, mesh size, pH) are available upon request for OEM projects.

| Methylene Blue Adsorption (mg/g, min) | 200 - 250 | ASTM D2330 |
| Moisture Content (as packed, max) | 5% | ASTM D2867 |
| Ash Content (max) | 5% | ASTM D2866 |
| Hardness (min) | 95% | ASTM D3802 |
| Bulk Density (kg/m³) | 450 - 550 | ASTM D2854 |
| Mesh Size (Standard) | 8x30 / 12x40 / 20x50 | ASTM D2862 |
| pH (of slurry) | 6.5 - 8.0 | ASTM D3838 |
This bulk activated charcoal for water filters is versatile enough to serve a wide range of industrial and municipal applications:
Choosing the right media directly impacts operational costs and system longevity. Our bulk media offers distinct advantages:
As a leading supplier of bulk activated charcoal for water filters, we differentiate ourselves through technical expertise and supply chain reliability:
A: Granular Activated Carbon (GAC) has a larger particle size (typically 0.2-5mm) and is used in fixed-bed columns or pressure filters. Powdered Activated Carbon (PAC) is a fine powder (typically <0.18mm) used in batch treatment processes, such as direct dosing into clarifiers or mixing tanks, where it is later removed by sedimentation or filtration.
A: The correct mesh size depends on the flow rate, pressure drop limitations, and the specific contaminant. For general water filtration, 12x40 mesh is a common standard. For high-flow or low-pressure systems, 8x30 may be preferred. We recommend consulting our technical team to calculate the optimal Effective Bed Contact Time (EBCT) for your application.
A: Yes, our coal-based and coconut-based GAC can be thermally regenerated (typically at 800-900°C in a controlled atmosphere) to restore its adsorptive capacity. However, regeneration is most economical for large-volume industrial applications. For smaller systems, replacement with fresh media is often more cost-effective.
A: When stored in a cool, dry environment away from direct sunlight and volatile chemicals, the shelf life is indefinite. However, we recommend usage within 2 years of the production date to ensure optimal moisture content and performance. Opened bags should be resealed to prevent moisture adsorption.
A: Yes, we provide free samples (typically 1kg or 5kg) for qualified buyers. You only need to cover the shipping cost. Please contact our sales team with your application details and target mesh size to request a sample.
A: The MOQ for standard bulk activated charcoal for water filters is typically 1 metric ton (40 x 25kg bags) or a 20-foot container (approx. 20 MT). For custom specifications (e.g., specific mesh or acid-washed), the MOQ may be higher. Please inquire for specific project requirements.
