Drinking Water Purification Coconut Shell Carbon

Many water treatment plants and users of water purification equipment often encounter a puzzling question: Why does the taste of the water after using activated carbon still not improve? Or, after using it for a short period of time, "black water" appears and the pressure difference rises sharply?
Drinking Water Purification Coconut Shell Carbon from Huajing provides the answer. Unlike coal-based carbon which has high ash content and a single pore structure, coconut shell carbon originates from natural coconut shells. Its surface is extremely hard and the pores are mainly micropores (with a pore diameter of 2nm or less), which precisely match the molecular sizes of residual chlorine, small organic molecules, and some heavy metal ions. After more than 20 years of production, we have accumulated real data: After treating tap water with Huajing coconut shell carbon, the removal rate of residual chlorine can reach over 99%, the odor threshold can be reduced by more than 80%, and the turbidity of the effluent can be stably controlled below 0.5 NTU.

Technical Specifications

Core advantage

Safety
Food-grade safety, worry-free drinking water: The raw materials are natural and the purification process is strict. They comply with the standards of GB/T 12496 and GB 17323. Heavy metals such as arsenic, lead, and cadmium are far below the limit, and they can be used for direct drinking water terminal filtration.

Efficient
Rich in micropores and with strong purification ability: Specific surface area ≥ 1000 m²/g, iodine value ≥ 1000 mg/g. It can quickly remove residual chlorine (removal rate ≥ 95%), odor, off-color, organic matter, pesticide residues and heavy metals.

Durable
Highly resistant to water flushing, non-fouling: Mechanical strength ≥ 97%. No disintegration during backwashing / long-term immersion. Low dust, clear water output, long filter element lifespan (8–12 months).

Stable and durable
Chemically stable, wide adaptability: Drinking Water Purification Coconut Shell Carbon is resistant to acids and alkalis, corrosion-resistant, suitable for various water sources such as municipal tap water, groundwater, well water, etc., and maintains stable performance within the pH 6–9 range.

Typical application scenarios:

Domestic / Commercial Water Purification Equipment: Water purifiers, pure water machines, central water purifiers, filter cartridge filling for drinking water machines, improving taste, removing residual chlorine and odors.
Deep treatment in water treatment plants: Filter beds / filter tanks filling, removing trace organic matter, disinfection by-products, color and odor, improving the quality of water leaving the plant.
Direct drinking water stations in residential areas / schools: Terminal fine filtration to ensure safe direct drinking water, sweet taste.
Food and beverages / bottled water: Water purification, decolorization and deodorization, meeting food hygiene standards.
Swimming pools / aquariums: Removing organic matter, odors, trace chlorine from water, improving water transparency and odor.
Years of service experience show that Drinking Water Purification Coconut Shell Carbon needs to be matched with corresponding mesh numbers in different scenarios: Domestic filter cartridges commonly use 12–30 mesh; Filter beds in water treatment plants commonly use 6–12 mesh; Small direct drinking machines are recommended to use 20–40 mesh. Our company can provide free selection and filling schemes based on water source quality, flow rate and equipment type to avoid blind purchasing.

FAQ

Q1: Is it necessary to clean the Drinking Water Purification Coconut Shell Carbon before use?
A: It is recommended to rinse with clean water or soak for 1-2 hours to remove the very small amount of powder produced during transportation. If used in a large filter, backwashing can be performed until the drainage is clear.

Q2: How often should it be replaced?
A: This depends on the water quality and flow rate. Generally, water treatment plants recommend replacement every 6-24 months; for household water purifiers, it is recommended every 6-12 months. Regular testing of residual chlorine and COD in the effluent can be conducted. When the removal rate drops below 60%, replacement is necessary.

Q3: Will harmful substances be released?
A: No. Huajing has passed the water-related hygiene safety license and has undergone tests for heavy metals, arsenic, lead, etc. (attached is the test report page), and complies with the GB/T 13803.2-1999 standard.

Q4: Do we have food-grade qualifications?
A: Yes. Huajing holds the "National Industrial Product Production License" and the "Water-related Hygiene Safety License Approval Document", and is a famous brand product in Hebei Province.
