Granular Activated Carbon — Iodine 1200
1,279.13mg/g iodine, lab-testedOur highest-adsorption grade, independently measured at 1,279.13 mg/g iodine.
Bogor, West Java—Tested to SNI 06-3730-1995
Custom iodine grades, thermally activated at our own plant in Bogor. Coarse, medium or fine mesh, made to order.
We manufacture granular activated carbon at our own facility in Tanjungsari, Bogor, West Java. Our carbon is produced for two demanding duties in particular: purifying water, and capturing dissolved metals from industrial process streams.
Iodine number is the figure that decides whether activated carbon is right for your application, so we build each grade around the number you need — below 1,000, above 1,000, or 1,200 mg/g — rather than asking you to work around a fixed catalogue.
We serve small trial quantities and large recurring contracts on the same terms of quality, and we publish our independent laboratory figures openly so you can compare before you commit.

Why Mega Karbon
Every attribute below is a measured value from an independent Sucofindo report, not a marketing adjective.
Three iodine grades, each traceable to its own laboratory report. Any grade is available in all three mesh fractions.
Our highest-adsorption grade, independently measured at 1,279.13 mg/g iodine.
High-grade carbon for demanding purification, tested at 1,137.27 mg/g iodine.
A cost-efficient working grade for everyday filtration, tested at 929.27 mg/g iodine.
Size Options
Granule size sets the balance between contact time and pressure drop in your filter bed. Tell us the duty and we will recommend the fraction.
Mesh 4x8
Largest granule. Low pressure drop — suited to high-flow filter beds.
Mesh 6x12
The general-purpose fraction, balancing contact time against flow resistance.
Mesh 8x30
Highest surface area per bed volume for demanding adsorption duty.
Independent Lab Results
Three production batches analysed by IDSurvey / PT Sucofindo to SNI 06-3730-1995. Not a summary and not a picture of a certificate — the actual numbers, side by side, in text you can copy.

Removing colour, odour, chlorine and dissolved organics from drinking water, process water and wastewater streams.
Adsorbing dissolved metals from industrial process liquids — one of the two applications our carbon is produced for.
General-purpose adsorption duty where high pure-carbon content and a clean, dust-free granule matter.
Packaging
Activated carbon adsorbs moisture from the air, so packing is part of the specification — not an afterthought.

Woven sacks with a sealed inner liner, so ambient moisture never reaches the pore structure in storage or transit.

Every bag is weighed as it is filled, so net weight per sack stays consistent across the batch.

Sealed sacks stack flat and travel palletised — tell us your handling equipment and container plan and we pack around it.
Production
We would rather show you than tell you. Buyers and partners are welcome at our Tanjungsari facility to walk the production line, watch a batch being activated, and see how quality control is run before carbon is packed.
Plain-language explanations of the numbers buyers are asked to compare.
Self-declared specs are claims, not proof. How independent Sucofindo testing works, and how to use lab reports to compare suppliers.
