Bone Char 8x24 Mesh is a coarse granular bone charcoal media sold by the pound for water filtration applications.
Bone char is commonly used in water filter designs for fluoride reduction and for adsorption of certain organic and inorganic species, including color bodies and many heavy metals. It can be used in numerous bone char water filter designs and in combination with standard granular activated charcoal filters.

Bone Char Media Information
Bone Char 8x24 Mesh is a carbonaceous adsorbent manufactured from the treatment and carbonization of selected grades of animal bone.
Bone char differs from activated carbon because it contains both carbon surface area and hydroxyapatite lattice surface area.

| Metal | Capacity (mg/g) | Linear Velocity (m³/hr) | Removal Efficiency |
| Aluminum | 24 | 1 | > 80% |
| Arsenic III | 30 | 0.5 | > 80% |
| Arsenic V | 26 | 0.5 | > 80% |
| Cadmium | 15 | 0.5 | > 80% |
| Chromium III | 15 | 0.5 | > 80% |
| Chromium IV | 8 | 0.5 | ≈ 50% |
| Copper | 50 | 3 | > 90% |
| Iron | 30 | 3 | > 80% |
| Lead | 151 | 3 | > 90% |
| Manganese | 50 | 3 | > 80% |
| Mercury | Undetermined | 0.5 | ≈ 50% |
| Nickel | 45 | 3 | > 90% |
| Silver | Undetermined | 0.5 | ≈ 50% |
| Zinc | 37 | 3 | > 90% |
Capacity for mercury and silver is undetermined due to the nature of adsorption. Removal efficiency for mercury and silver is highly dependent on other species in the stream. All figures are subject to ongoing research and updating.
Adsorption of Metals
- Aluminum: Very effective in removing soluble aluminum. Adsorption is influenced by pH and retention time. Best results at pH 7 or above.
- Arsenic: Largely dependent upon the form of arsenic, such as AsIII or AsV. pH has considerable influence. At low pH, almost no adsorption occurs.
- Cadmium: Bone char is listed as better than conventional precipitation and/or coagulation processes. Superior results are listed in soft water.
- Chromium: Performance depends upon the form present and valency, such as chrome III or chrome VI. Chrome III adsorbs well.
- Copper: Adsorption is dependent upon pH and retention time.
- Iron: Performance depends upon the form of iron. Better results are listed with organic iron than inorganic iron.
- Lead: Listed as very effective with short retention time, such as 1 minute or less.
- Manganese: Listed as very effective, with good pilot results.
- Mercury: Best with organic mercury. Inorganic mercury performance depends upon valency.
- Nickel: Adsorption is best at higher pH and requires high retention time. At pH 5, almost no adsorption occurs.
- Silver: Quite rapidly adsorbed and better at low concentrations in solute. High deposits of silver on bone char inhibit adsorption.
- Zinc: Efficiency is dictated by contact time and pH.
Adsorption of Non-Metals
- Bromine: Bone char is effective in removing free bromine. Bromine form is important. In the presence of potassium and sodium, adsorption decreases.
- Chlorine / Chloramines: Bone char is minimally effective in reducing chlorine or chloramine.
- Color: Retention time required is usually about 6–15 minutes, depending upon the chemical makeup of the color.
- Fluoride: Adsorption onto bone char is good, but influenced by pH. It performs better at 6.5 or lower. Concentrations of fluoride present also influence performance. Activated carbons do not effectively adsorb fluoride.
- Pesticides: Good at removing organo-chlorine pesticides, such as Dieldrin and septachlor. Not very good at atrazine.
