Coconut shell activated carbon specially used for water purification is a high-efficiency water purification material made from coconut shells as the main raw material through elaborate processing. Coconut shells undergo complex processes such as carbonization and activation to form black granular or powdered activated carbon with a rich porous structure. This kind of activated carbon can effectively remove various pollutants in water, including organic pollutants, odors, residual chlorine, heavy metal ions, etc., thereby significantly improving water quality. It is an excellent choice in fields such as drinking water purification and sewage treatment.
Specific parameters:
Iodine value: The iodine value is relatively high, generally ranging from 800-1200mg/g. The iodine value is an important indicator to measure the adsorption capacity of activated carbon for small molecular substances. A high iodine value indicates that it has a strong adsorption capacity for small molecular organic pollutants in water (such as pesticide residues, benzene series, phenols, etc.).
Particle size: The particle size of granular activated carbon is usually between 0.5-2.0mm, which is convenient for filling into various water purification equipment, such as filters and adsorption towers, and can form a good filter layer; most powdered activated carbon can pass through 80-200 mesh sieves (particle size less than 0.18-0.075mm). The small particle size allows the activated carbon to disperse quickly in water and make more sufficient contact with pollutants.
Specific surface area: The specific surface area is relatively large, usually between 1000-1500m²/g. The huge specific surface area provides a large number of adsorption sites for pollutants in water. Whether it is macromolecular colloids, microorganisms, or small molecular soluble harmful substances, they can be effectively adsorbed on the surface of activated carbon.
pH value: The pH value range is roughly between 4-10. Within this acid-base range, activated carbon will not cause significant changes in the acidity and alkalinity of water, can adapt to the treatment environment of most drinking water and industrial wastewater, and ensure the stability of the water purification process.
Ash content: The ash content is relatively low, generally between 3%-8%. A lower ash content means that the activated carbon has a higher purity, which can reduce secondary pollution to water quality during the water purification process and ensure the water purification effect.
Uses:
Drinking water purification: It can remove residual chlorine in water and improve the taste of water. Residual chlorine is a substance remaining in the tap water disinfection process. Long-term drinking of water containing excessive residual chlorine may have adverse effects on human health. Coconut shell activated carbon can effectively adsorb residual chlorine, making the taste of water fresher.
It can reduce the content of organic pollutants in water. It can adsorb organic pollutants such as pesticide residues, polycyclic aromatic hydrocarbons, and halogenated hydrocarbons in water. These substances may come from agricultural non-point source pollution, industrial wastewater discharge, or tap water pipeline pollution. Through adsorption, their concentration in water is reduced, and the safety of drinking water is improved.
It can adsorb heavy metal ions in water, such as mercury, lead, cadmium, etc. Although the content of heavy metal ions in water is usually low, long-term accumulation may cause serious harm to the human body. Coconut shell activated carbon can adsorb these heavy metal ions and reduce their content in water.
Sewage treatment: In industrial wastewater treatment, it is widely used in chemical, pharmaceutical, printing and dyeing, electroplating and other industries. For chemical wastewater, it can adsorb various organic synthetic raw materials, intermediates and products; drug residues and antibiotics in pharmaceutical wastewater; dyes and auxiliaries in printing and dyeing wastewater; heavy metal ions in electroplating wastewater, etc. Through adsorption, it reduces indicators such as chemical oxygen demand (COD), biochemical oxygen demand (BOD), chromaticity, and heavy metal content of wastewater, so that the wastewater meets discharge standards or is convenient for subsequent advanced treatment.
In domestic sewage treatment, it is used for advanced treatment after secondary biological treatment to further remove residual organic matter, ammonia nitrogen, phosphorus and other pollutants in water, as well as disinfection by-products and odors, and improve the recycling value of sewage. For example, the treated sewage can be used for urban landscape water, road cleaning, industrial cooling water, etc.
Product advantages:
Excellent ability to remove odors and odor compounds: The main advantage of using coconut shell-based media is that it is dominated by micropores (diameter < 2nm). The size of this structure is very suitable for capturing specific organic molecules that cause earthy, musty or chemical tastes in tap water, such as geosmin and 2-methylisoborneol (MIB). Compared with coal-based alternatives, our coconut shell activated carbon has a higher removal efficiency for these trace pollutants per unit volume. This efficiency enables point-of-use (POU) filter manufacturers to design compact filter cartridges for excellent taste improvement. As an experienced manufacturer of coconut shell activated carbon, we 深知 that sensory quality is a key performance indicator for our customers in the bottled water and household filtration fields.
High hardness, durability and renewability: Operating costs are a major concern for water utilities. Our products have high mechanical strength and wear resistance, which stems from the dense cell walls of coconut shells. This durability is crucial during the "backwashing" phase of water treatment, when the carbon bed is fluidized to remove trapped particles. Low-quality carbon may wear during this process, leading to media loss and increased turbidity. Our granular activated carbon can withstand these physical forces, ensuring a longer service life. In addition, for large-scale users, the high integrity of the particles makes thermal regeneration a viable option, supporting sustainable operation strategies and reducing total cost of ownership.
Broad-spectrum pollutant control capability: Although specifically targeted at micro-pollutants, our activated carbon also provides protection against various water quality problems. It can effectively reduce chemical oxygen demand (COD) and, when treated or given sufficient contact time, can adsorb specific heavy metal ions such as lead and mercury. The material acts as a multifunctional barrier in multi-stage treatment systems, protecting sensitive ion exchange resins or reverse osmosis membranes from organic pollution and chlorine oxidation. This versatility makes us the preferred supplier of coconut shell activated carbon for integrated water resource management projects, able to provide media that can solve multiple water quality problems simultaneously.
High iodine adsorption capacity, effective removal of chlorine and organic matter: Our water purification activated carbon is specially made from high-quality coconut shells, with attention to density and purity in material selection. Through high-temperature steam activation (800-1000°C), we produce materials with an extremely developed microporous structure, with an iodine value of 800-1200 mg/g. This high specific surface area (1000-1500 m²/g) is the technical basis for its excellent performance in capturing small molecular pollutants.[1] It is particularly effective in adsorbing residual chlorine, disinfection by-products (DBPs) and volatile organic compounds (VOCs) that affect the taste and safety of drinking water.[1] For buyers evaluating coconut shell activated carbon suppliers, our products have the high adsorption capacity required for high-end filtration applications, ensuring that the filtrate meets strict drinking water standards without introducing unpleasant tastes or odors.
Optimized particle morphology to improve hydraulic efficiency: To ensure compatibility with various filter vessels, our coconut shell activated carbon is processed into precise particle morphology, usually with a particle size range of 0.5mm-2.0mm (standard mesh sizes are available). This particle size distribution is carefully designed to balance adsorption kinetics and hydraulic flow rate. In fixed-bed filters, uniform particles allow water to pass with minimal pressure drop while maximizing contact time with the carbon surface. The natural hardness of the material prevents it from breaking under the hydraulic stress of backwash cycles. Unlike softer media that may fragment and cause channeling or clogging, our granular activated carbon maintains the integrity of the filter bed, reliably blocking pollutants in both household water purifiers and large industrial filter columns.
Purity and safety, suitable for food-grade applications: Safety is crucial in water treatment. Our production process includes strict screening and cleaning stages to minimize ash content (usually 3-8%) and remove floating impurities. The resulting high-purity activated carbon will not leach heavy metals or phosphates into the treated water. The pH value is maintained between 4-10 to ensure that it does not significantly change the water chemistry of the effluent.[1] These specifications make it ideal for the food and beverage industry, where water quality directly affects the final product. By controlling raw materials and activation environment, we ensure that our activated carbon is a clean, renewable filter medium that protects both downstream equipment (such as reverse osmosis membranes) and consumers.
