Based in Liyang, Jiangsu, Sanniu Activated Carbon has spent over a decade specializing in adsorption materials, evolving from a single-product activated carbon manufacturer into a full-chain environmental materials service provider integrating R&D, production, sales, technical service, and self-managed export. The company offers a complete portfolio spanning coal-based, coconut shell, wood-based, bamboo-based, and fruit shell activated carbon, and has independently developed high-efficiency physical adsorption activated carbon and low-impurity plant-based activated carbon. Through targeted modification processes, its products are precisely tailored to diverse applications including ternary lithium cathode material purification, black mass recovery, water treatment, gold refining, food and pharmaceutical use, VOC waste gas treatment, and desulfurization and denitrification. Distinguished from ordinary raw material suppliers, Sanniu delivers customized purification solutions for the non-ferrous metals, water treatment engineering, pharmaceutical and food, thermal power, and chemical industries, and with its import-export qualifications serves both domestic and overseas environmental protection markets. From a glass of clean water to compliant industrial exhaust, and from local plants to overseas projects, Sanniu delivers the purifying power of Chinese manufacturing through core materials technology.

PRODUCT FORMS
Block and pelletised activated carbon
Extruded or crushed block carbon with low pressure drop for deep beds, gas-phase service and installations where dust must be kept low.
Powder activated carbon
Fine powder for batch dosing, decolourisation and short contact-time treatment, where the adsorption rate matters more than bed life.
Granular activated carbon
Granular media for fixed-bed adsorption and filtration. Compare particle size, pressure drop and handling needs.
APPLICATIONS
Water treatment
Activated carbon selection for water polishing, colour and odour control. Share the water analysis and treatment targets.
Food, beverage and refining
Decolourisation and purification in sugar, syrup, edible oil and beverage processing, where colour bodies and off-flavours have to be removed.
Air and gas purification
Odour control, solvent recovery and flue gas treatment, where the carbon has to hold up in the gas phase rather than in a water column.

Coconut Shell Activated Carbon for Gold Recovery in CIL/CIP Circuits
Coconut shell activated carbon for gold recovery in CIL and CIP circuits, where hardness and a defined particle cut support screening and slurry duty. This granular series is offered with iodine value, methylene blue adsorption, bulk density and ball-pan hardness ranges that help buyers compare grades. Published values describe the series; the actual batch certificate and test method are confirmed before quotation, so plants can check figures against incoming material.
Low Dust Activated Carbon for Clean Air and Water Treatment
Low-dust activated carbon made from hard coconut shell yields strong granular carbon for air and water treatment, where fine particles matter: a screened, low-fines product supports cleaner refill work, steadier flow and less load on downstream filters. Share your medium, flow or concentration, target specification, mesh fraction and quantity, and we will confirm the suitable grade, batch values and documents before quotation.
Activated Carbon for Wastewater Treatment: Granular Coal-Based Grade for Color and COD Reduction
Granular coal-based activated carbon helps wastewater treatment plants reduce colour, COD and dissolved organic load in packed beds and filters. Its hard, dense grains suit backwashing, while a developed pore structure adsorbs colour bodies and residual organics. Batch samples are confirmed against references such as iodine value of at least 900 mg/g before quotation. As effluent chemistry, contact time and mesh affect performance, share your water analysis, target COD and flow for a specification review.
Activated Carbon for Mercury Removal: Selecting the Right Grade for Flue Gas and Process Streams
Mercury removal from flue gas and process streams calls for more than one adsorption number. Coal, coconut, wood, nutshell and bamboo series offer a range of pore structures and particle sizes to compare against your gas conditions and target duty. Selection starts with micropore development, surface area, hardness and particle size. Series references such as iodine value, BET and CTC are shown here; batch figures, packing and documents are confirmed before quotation.
Activated Carbon for Food and Beverage Processing: Coconut Shell Grades for Purification, Decolorization and Taste Control
Coconut shell activated carbon is a practical choice for food and beverage purification, decolorization, and taste control. Its hard, dense structure gives a micropore-rich network that captures small dissolved organics while resisting breakdown in fixed beds. This grade suits sugar syrups, edible oils, beverages, and process water. Share your treatment target, flow rate, contactor type, and particle size needs, and we will confirm the suitable grade and batch specification before quotation.
Coconut-shell activated carbon for filtration
Coconut-shell activated carbon combines a microporous structure with high hardness. It is commonly considered for drinking-water and terminal filtration, subject to application evaluation.
