Coconut Shell Specialization
Selected coconut shells support high hardness, low ash, micropore structure, and attrition resistance for premium activated carbon.
Consistent Quality
Quality control starts at raw material selection and continues through activation, sizing, packing, and final assurance.
Application-Specific Grades
Granular, powder, impregnated, and catalytic formats are matched to contaminant profile, contact time, and operating conditions.
Supply Reliability
Company-owned manufacturing, 35000 metric tons annual capacity, and final quality assurance before shipment support consistent coconut activated carbon supply.
Technical Support
Sales and technical teams review application conditions, target contaminants, mesh size, activity, and compliance requirements before recommending a grade.
Certifications & Compliance
NSF 42, NSF 61, and California Prop 65 compliant. Ready for regulated and food-grade applications.
CATCARB for chloramine and H2S reduction
Surface-modified coconut shell catalytic carbon for water-treatment systems that need faster chloramine and hydrogen sulfide decomposition.
- Built for chloramine-heavy drinking-water programs
- Also suited for hydrogen sulfide decomposition
- Maintains the hardness and attrition resistance expected from premium coconut shell carbon
Controlled from coconut shell selection to final shipment
Black Opal works from selected coconut shell feedstock through controlled activation, sizing, and final quality checks so each grade is built for repeatable adsorption performance.
Grades can be customised by mesh size, adsorption level, pH adjustment, washing, and impregnation requirements instead of forcing every application into the same carbon.
Resources and brand updates
Technical notes and brand notices stay tied to the same products, facilities, and support channels buyers already work with.
Name Change Press Release
Black Opal announced the completion of its transition from INDOCARB AC to Black Opal Carbons as part of a broader global branding effort.
Brand updateCatalytic Carbon
Technical notes on catalytic activated carbon performance, chloramine reduction, and specialty water-treatment use cases.
