Washed activated carbon is a specially processed activated carbon product that has undergone a water washing treatment to remove most impurities and ash content, making it purer and suitable for applications that require high purity. It can effectively remove organic matter, chlorine, oil, colorants, odor, heavy metals, and other pollutants in water, and it also has wide applications in gas purification, food processing, pharmaceutical industry, and other fields.

Acid-washed activated carbon is made of selected anthracite or coconut shell raw materials, and is refined through more than ten processes including activation, crushing and screening, fine washing and dust removal, and acid washing. The acid washed activated carbon granular has very little floating powder, greatly reduces the turbidity of the outlet water, and multiple rinses to ensure the product is pure, safe and reliable, and is cleaner and lower in ash than the activated carbon on the market.

Wood granular activated carbon selects high-quality hardwood chips, coconut shells, etc. as raw materials, and is made through crushing, mixing, granulation, drying, carbonization, and activation. The unique production process of Heika makes the product have the characteristics of large specific surface area, strong decolorization ability and developed pore size. Wood based granular activated carbon have Well-developed mesopore structure and specific surface area,high adsorption capacity and fast filtration speed. High strength and low ash, reasonable pore size distribution; high ignition point.

Coconut granular activated carbon is a charcoal made from high quality coconut shell, which is thermally activated in an atmosphere with highly reducing characteristics. Being of vegetable origin, it does not contain metals or other contaminants present in mineral coals. Coconut shell granular activated carbon goes through carbonization, steam activation, sieving and other processes, has a large surface area and high microporous density. Coconut shell carbon is used in water treatment, gold recovery, food & beverage, catalyst carrier, pharmaceuticals and so on.

Coal based granular activated carbon is an activated carbon material made from coal as raw material. Coal-based activated carbon is mainly used for high-end air purification, waste gas treatment, waste incineration, high-purity water treatment, wastewater treatment, sewage treatment, aquaculture, desulfurization, denitrification, and can remove impurities and pollutants in gases and liquids to a limited extent, as well as various gas separation and purification. It can also be widely used in the adsorption and recovery of various low-boiling point substances, deodorization and oil removal, etc. That coal based granular activated carbon bears fully developed porous structure, large specific surface area (especially large micropore volume), and great hardness, which leads to an extremely adsorption ability to organic substances and free chlorine in water and harmful components in air as well.
