ALUMINUM
Very effective in removing soluble aluminum. Adsorption influenced by pH and retention time. Best results at ph 7 or above.
ARSENIC
Largely dependent upon form
of arsenic (ie. AsIII or AsV). pH has considerable influence. At low pH
almost no adsorption occurs. Affected by Protonation.
CADMIUM
Bone char is better than
conventional precipitation and/or coagulation processes. Superior
results in soft water. Retention time on par with aluminum.
CHROMIUM
Much dependent upon form present, ie. cation or anion, and valency (chrome III or chrome VI). Chrome III adsorbs well.
COPPER
Adsorption dependent upon pH and retention time.
IRON
Dependent upon form of
iron. Better results with organic iron than with inorganic. Inorganic
results dependent upon valency. Short retention times suffice.
LEAD
Very effective with short retention time (ie. 1 minute or less)
MANGANESE
Very effective. Pilot results good. Competition from other methods of oxidation.
MERCURY
Best with organic mercury.
Inorganic mercury is dependent upon valency (mercury I and II).
Although similar, the higher charged monatomic mercury II has a greater
affinity for Bone Char than mercury I.
NICKEL
Adsorption best at higher pH. Requires high retention time. At 5 pH almost no adsorption.
SILVER
Quite rapidly adsorbed.
Better at low concentrations in solute. High deposits of silver on bone
char inhibit adsorption. Adsorption better at pH 5.
ZINC
Efficiency dictated by contact time and pH. Both pilot plant and full scale plant performance good.
ADSORPTION of NON-METALS
BROMINE
Bone Char is effective in
removing free bromine. Bromine form is important too. In presence of
potassium and sodium adsorption decreases.
CHLORINE
CHLORAMINES
Bone Char is minimally effectively in reducing chlorine or chloramine.
COLOR
Retention time required is
usually about 6 – 15 minutes, dependent upon chemical make up of color.
Can be used in slow sand, rapid gravity or pressure filters.
FLUORIDE
Adsorption onto Bone Char
is good, but influenced by pH – better at 6.5 or lower. Concentrations of
fluoride present also influences performance. Activated carbons do not effectively
adsorb fluoride.
PESTICIDES
Good at removing organo-chlorine pesticides (ie. Dieldrin, septachlor, etc.). not very good at atrazine, etc.

HEAVY METAL & FLUORIDE REMOVAL
BONE CHAR 20x60 (fine granular bone charcoal) is produced from aged bones. It’s surface area and base material lends itself to the adsorption of a range of toxic heavy metals including lead, aluminum, manganese, silver as well as non-metals including fluoride and bromine. View LINKS below.
Rinse off any charcoal dust before application.
Fine Mesh Size: 20 x 60 (See Size Chart below)
