Product Overview
High activity coal powder carbon B-90 is a high-activity coal-based powdered activated carbon delivering an iodine adsorption value exceeding 900 mg/g for enhanced municipal and industrial water treatment. Manufactured from premium bituminous coal through steam activation, it provides superior organic removal compared to standard 800 mg/g grades.
The elevated adsorption capacity makes B-90 ideal for municipalities facing higher organic loading, industrial facilities requiring tighter effluent control, and chemical processors needing reliable impurity removal. The 8–11 pH and controlled ash content ensure compatibility with conventional treatment chemistries.
Key Application Areas
- Municipal Drinking Water — Handles higher organic loading events and provides greater safety margin for taste and odor control in surface water plants.
- Urban & Industrial Wastewater — Treats combined municipal-industrial streams and shock loads that overwhelm lower-capacity grades.
- Chemical Purification — Purifies process intermediates and final products where trace organics affect quality or catalyst performance.
- Bio-Activated Carbon Systems — Supports advanced biological-carbon hybrid processes with higher adsorption capacity for non-biodegradable fractions.
- Seasonal Algae & Organic Events — Provides rapid response to cyanobacteria blooms and natural organic matter spikes in reservoir-fed systems.

- Compatible with Conventional Treatment: pH 8–11 and controlled particle size work with standard coagulation, sedimentation, and filtration trains without process modification.
How B-90 Delivers High Activity Coal Powder Carbon Performance
Standard powdered activated carbon with 800 mg/g iodine performs reliably under normal conditions. However, during algae blooms, stormwater runoff, or industrial discharge events, organic concentrations spike beyond the capacity of standard grades. In these scenarios, lower-activity carbon may require proportionally higher dosing or extended contact times to maintain equivalent removal targets under elevated organic loading.
B-90 solves this through enhanced micropore development. The optimized steam activation protocol creates additional adsorption sites across the coal matrix, achieving >900 mg/g iodine—10–15% higher capacity than standard 800 mg/g grades. This extra margin extends treatment effectiveness during peak loading without requiring dosage increases. In municipal water plants, this means maintaining taste-and-odor control during cyanobacteria blooms. In industrial effluent treatment, it provides the safety margin needed for variable COD streams. The result is predictable high activity coal powder carbon performance even when source water quality deteriorates.
B-90 vs Standard and Premium Powdered Grades
| Model | Iodine Adsorption Value | Moisture Content | Ash Content | PH | Specific Surface Area | Particle Size <200 Mesh |
|---|---|---|---|---|---|---|
| B-80 | >800 | <10% | <15% | 8-11 | >800 | >90 |
| B-90 | >900 | <10% | <15% | 8-11 | >900 | >90 |
| B-A0 | >1000 | <10% | <15% | 8-11 | >1000 | >90 |
B-80 (>800 mg/g) provides reliable performance for standard municipal duty at the lowest cost. B-A0 (>1000 mg/g) offers maximum capacity for critical drinking water systems or high-purity chemical processing. B-60 serves industrial wastewater and flue gas applications with similar 800 mg/g specifications.
B-90 bridges this gap as the enhanced-performance tier. It provides the higher adsorption margin needed for demanding municipal and industrial applications without the premium price of B-A0. For municipalities with variable source water or industrial plants facing tighter discharge limits, B-90 delivers the optimal balance of capacity and cost as a high activity coal powder carbon. Choose B-80 for steady-state operations; select B-90 when organic loading is variable or effluent standards are stringent; reserve B-A0 for peak-demand and emergency response.
