When sourcing high‑performance granular activated carbon (GAC) for water treatment, air and gas purification, food & beverage, chemical, or pharmaceutical applications, choosing the right manufacturer or supplier is critical. Sri Lanka has emerged as a major global hub for activated carbon, especially coconut shell–based GAC, thanks to its abundant raw materials and strong export infrastructure. At the same time, many international buyers also look to leading Chinese producers like Guangdong Tongke Activated Carbon Co., Ltd. for reliable, cost‑effective, and fully customizable granular activated carbon solutions.
This guide introduces the top granular activated carbon manufacturers and suppliers in Sri Lanka, with a special focus on Guangdong Tongke as a premier global partner for industrial GAC projects.
Granular activated carbon is one of the most widely used forms of activated carbon, valued for its high surface area, excellent adsorption capacity, and mechanical strength. GAC is typically produced from coconut shell, coal, or wood and is used in fixed‑bed filters for:
- Municipal and industrial water treatment (removal of chlorine, organics, taste, odor, VOCs, pesticides, etc.)
- Air and gas purification (odor control, solvent recovery, VOC abatement, mercury removal)
- Food and beverage processing (decolorization, purification of sugar, edible oils, alcohol, soft drinks)
- Chemical and pharmaceutical manufacturing (catalyst support, purification of intermediates and APIs)
- Gold and precious metal recovery (carbon‑in‑pulp, carbon‑in‑leach processes)
Because GAC performance depends heavily on raw material, activation method, particle size, and quality control, selecting a reputable granular activated carbon manufacturer or supplier is essential for long‑term process efficiency and compliance.
Guangdong Tongke Activated Carbon Co., Ltd., based in Dongguan, Guangdong Province, China, is a professional granular activated carbon manufacturer and supplier with over 20 years of experience in the activated carbon industry.
