Coconut Activated Carbon for Water Purification | Food Grade Acid Washed Coconut Shell Carbon Manufacturer

Yihang Carbon is a professional manufacturer with 30 years of experience in activated carbon production. We have an independent in-house quality inspection department to strictly control product quality throughout all production procedures, supplying high-purity and stable coconut shell activated carbon for water purification industries.

Our product is made of premium coconut shells imported from Southeast Asia through sophisticated processes including high-temperature carbonization and steam activation. It is widely applied in municipal drinking water treatment, household water purification and bottled water filtration. We also supply food-grade deeply acid-washed granular coconut activated carbon for high-end pure water production and other demanding sectors.

This carbon features highly developed microporous structures with large specific surface area and outstanding adsorption capacity. It boasts superior mechanical strength, great wear resistance and low dust generation during operation, effectively preventing filter clogging and black water discoloration. Optimized specifically for drinking water treatment, it efficiently removes residual chlorine, discoloration, pungent odors, natural organic matter, trace heavy metals, disinfection by-products and other contaminants from water. It delivers clean, mild and sweet-tasting water, fully meeting strict standards for direct drinking water, pure water and bottled water.

Benefiting from consistent product quality and reliable supply chain, we have established long-term strategic cooperation with well-known brands including Nongfu Spring and Coca-Cola. Our products are sold across domestic markets and Southeast Asian countries, making them the preferred filter media for residential water filters, commercial water treatment systems and municipal water supply projects.

Ash Content	≤4% (≤2% for acid-washed grade)	Deep acid washing reduces impurities and inorganic salt precipitation to keep water crystal clear
pH Value	6.5~8.5	Compliant with drinking water standards, mildly conditions water and improves drinking taste
Apparent Density	0.45~0.55g/mL	Uniform packing density, excellent water permeability and low water flow resistance
Heavy Metal Content	Far below national drinking water standards	Food-safe raw material with no harmful substance leaching, suitable for direct drinking water treatment

Application Scenarios

Application Scope of Coconut Activated Carbon for Water Purification

Our coconut shell activated carbon serves full-range water purification scenarios with drinking water treatment as the core, covering four major sectors: household, commercial, municipal and beverage production, compatible with diverse equipment and water sources.

Uses of Coconut Shell Granular Activated Carbon.jpg

1. Household Water Treatment

Household water filters, integrated compact water purifiers, water filter pitchers and all types of filter cartridges as core filter media. It eliminates residual chlorine, pipeline odors and impurities in tap water, upgrades daily drinking taste and safeguards household water safety.

Household Water Filters & Cartridges – Improves taste, removes chlorine and odor
Under-sink & Countertop Water Purifiers – Enhances water quality for daily drinking

2. Commercial & Beverage Production

Applied in purified water manufacturing, bottled drinking water, barreled water and beverage production filtration. It is a widely adopted filter medium for water treatment procedures of famous brands including Nongfu Spring and Coca-Cola, stabilizing beverage flavor and product quality.

Bottled Water & Purified Water Production – Ensures consistent purity and flavor
Reverse Osmosis (RO) Systems – Post-carbon filtration for final polishing

3. Municipal Water Supply

For urban municipal tap water, surface water treatment and advanced groundwater purification. It removes microcystins, bacteria, parasites, endocrine disruptors, disinfection by-products and other contaminants to meet official safe drinking water standards.

Municipal Drinking Water Treatment – Removes organic pollutants and residual disinfectants
Groundwater & Well Water Purification – Reduces iron, manganese, and organic contaminants

4. Engineering Supporting Projects

Centralized residential water supply, large-scale water purification systems for schools, hotels and office buildings, groundwater impurity removal and quality improvement. Combined with ion exchange and other processes, it jointly eliminates inorganic water pollutants and fits large-volume water treatment working conditions.

Point-of-Use (POU) & Point-of-Entry (POE) Systems – Tailored for small to large-scale applications

Universal Specification Tip

Common mesh sizes used: 12×40 mesh and 8×30 mesh, delivering balanced optimal flow rate and adsorption efficiency.

FAQ

1. How to choose between 8×30 mesh and 12×40 mesh?

8×30 mesh features larger particles with fast water flow and low pressure drop, ideal for large water treatment equipment, municipal water supply, groundwater treatment and commercial pure water production lines.

12×40 mesh has medium-sized particles with larger contact adsorption area, delivering superior fine removal of chlorine and odor. It is the top choice for household water purifiers, compact water machines, filter cartridges and bottled water filtration. Both are standard mainstream sizes widely used in the water purification industry.

2. Is this coconut shell activated carbon safe for direct drinking water treatment?

Yes.

Our carbon adopts coconut shells imported from Southeast Asia and deep acid washing technology, classified as food-grade activated carbon for water treatment. We operate an independent QC department to test every single batch. The contents of heavy metals, ash and harmful impurities all comply with national safe drinking water standards without secondary contamination, suitable for high-standard scenarios such as direct drinking water and bottled water.

Our coconut activated carbon is specifically designed for drinking water purification, including household filters, bottled water, and municipal systems. It effectively removes chlorine, bad taste and odor.

3. What advantages does coconut shell carbon have over coal-based carbon for water purification?

Coconut shell activated carbon owns more developed micropores, offering stronger adsorption capacity for residual chlorine, odors and small-molecule organics in water. It has high mechanical strength and low dust output, so filter clogging rarely happens during long-term operation. With excellent chemical stability and acid & alkali resistance, it produces odor-free water with better taste. It is the premium dedicated filter medium for drinking water treatment and enjoys a longer service life than regular coal-based activated carbon.

4. What are the benefits of acid-washed coconut shell activated carbon?

Deep acid washing efficiently cuts ash and heavy metal content, preventing black water and white suspended solids during operation. It adjusts water pH to a comfortable range for drinking and greatly improves water taste. Additionally, it protects RO membranes and ultrafiltration membranes inside water equipment to extend their service life.

5. What mesh size do you recommend for household water filters?

We recommend 12×40 mesh for standard household water filters, and 8×30 mesh for systems requiring higher flow rates. Both sizes deliver outstanding adsorption performance with low pressure drop.

6. Do you supply well-known large beverage and water brands?

Yes. We maintain long-term stable cooperation with Nongfu Spring (China) and Coca-Cola, which fully proves the stable quality and reliable performance of our products.

7. Can you customize mesh sizes and packaging solutions?

Absolutely. We provide customized mesh specifications, packaging options including woven bags, iron drums and bulk shipments, plus professional technical support tailored to your actual application demands.

8. How does your factory guarantee stable product quality?

We have an independent in-house quality control department conducting full inspections for every production batch. We can provide official COA (Certificate of Analysis) for each shipment and support third-party laboratory testing upon clients’ requests.
