Coconut shell
One of the four bases used for this grade, alongside apricot, peach and walnut shell.
Shortlisting a fruit shell activated carbon manufacturer for a municipal, industrial or point-of-use water project comes down to three decisions: which shell base and mesh fit the filter bed, how the carbon behaves under backwash and regeneration, and how quickly a production-lot sample can reach your port. Tianyuan refines coconut, apricot, peach and walnut shells into granular and powder grades on one carbonization and activation line, then publishes the iodine, BET, strength and regeneration data buyers need to compare grades side by side. Use this hub to screen a fruit shell activated carbon supplier against those numbers, then send a quotation request that already names the mesh, iodine value, packaging and destination port.
Supply landscape
Fruit shell activated carbon reaches the market through shell-based producers, trading houses and resellers. The headline iodine value can look identical on three quotations while the shell sourcing, process control and replacement-batch behaviour differ completely. Screen the supply channel first, then spend your time on specifications.
| Sourcing question | Shell-based manufacturer | Trader / reseller |
|---|---|---|
| Shell source | Names the coconut, apricot, peach or walnut shell lots it feeds | Sells "fruit shell carbon" as one generic category |
| Process control | Screening, low-temperature carbonization at 500–700 °C, high-temperature activation at 800–1000 °C and purification | Resells finished stock; no process window to adjust |
| Grade change | Re-runs the line to shift mesh or iodine value | Limited to what is already in the warehouse |
| Custom treatment | Pickled, water-washed, modified and silver-loaded options | Usually not available |
| Sample | Production-lot sample cut alongside the quoted batch | Stock sample from an earlier import |
Two answers of "we would have to check with the plant" are normal. Five of them mean you are talking to a reseller.
Grade matrix
Two grades can share a mesh range and still behave differently in service, because bulk density, pore split and mechanical strength move together. Start from the published envelope below, then narrow to a model.
| Model | Indicators (customizable) | Published applications |
|---|---|---|
| TY-YKL1 | 10–24 mesh; 1050 mg/g; 95%; 6–8; 10% | Boiler / condensed water, semiconductor high-purity water |
| TY-YKL2 | 20–48 mesh; 900–1000 mg/g; 95%; 0.1 | Water purifier filters, food, high-purity water |
| TYK-TKL | 20–40 mesh; 950 mg/g; 95%; 7–9 | Wine decolorization, bitterness removal |
| TY-YKF | 150–325 mesh; 6–12 ml/0.1g; 90–95%; 10% | Drinking water, food |
Indicator values are shown as published on the product page; the line is customizable according to customer requirements.
One of the four bases used for this grade, alongside apricot, peach and walnut shell.
Fuller granules and the strongest published figure: 96% mechanical strength.
Slightly sharper edges than the other bases, with no obvious edges overall.
Particle integrity ≥96%, wear rate ≤2.5% after mechanical vibration testing, dry non-greasy feel.
Application selector
The same shell carbon is sold into drinking water plants, purifier cartridges, high-purity loops and sugar houses. Each duty stresses a different property, so read the card that matches your line and note the single fact you must confirm with the supplier.
Granular 12–24 mesh packed beds remove residual chlorine, odours, halogenated hydrocarbons and trace pesticide residues. Published outlet quality is ≤0.05 mg/L residual chlorine with odour below 20 odour threshold units, meeting GB 5749-2022, and organic adsorption runs 20–30% higher than coal-based activated carbon.
Confirm: residual chlorine removal above 99.5% target and strength ≥94% at a backwash intensity of 10–15 L/(m²·s).
24–48 mesh fine granular carbon is used as the core filter material, with a single cartridge published as processing 2–5 m³ of water.
Confirm: that the cartridge design accepts 24–48 mesh without excessive fines, and the mesh batch matches your filling equipment.
Fined and graded granular carbon serves boiler and condensed water duties, semiconductor high-purity water and power plant industrial pure water.
Confirm: the iodine value your loop requires and the strength the bed can lose before change-out, then check the TY-YKL1-style 10–24 mesh range.
Powder grades handle sugar industry decolorization: a 0.2–0.4% dosage removes caramel pigments and melanoidin and lifts whiteness above 92%. In wine production the carbon clarifies yellow rice wine and fruit wines, extending shelf life by 6–12 months, while juice and tea lines use it to lift astringency and tannic bitterness.
Confirm: powder or granular, depending on whether your plant runs a filter press or a packed bed.
Sewage treatment and fish farming water treatment are also listed application fields for this grade.

|---|---|---|
| Batch-to-batch consistency | 15% | Iodine value, mechanical strength and bulk density reported for the actual production lot |
| Raw material and process control | 12% | Named shell base, plus carbonization and activation inside the supplier's own process |
| Specification match | 15% | Mesh and iodine value aligned to your filter bed, cartridge or press |
| Mechanical durability | 12% | Strength ≥94% (walnut ≥96%); breakage below 1% at 10–15 L/(m²·s) backwash |
| Regulatory and food-grade fit | 10% | GB/T 12496-2015 for food-grade lots — arsenic ≤5 mg/kg, lead ≤20 mg/kg, mercury ≤0.1 mg/kg |
| Custom treatment capability | 10% | Pickled, water-washed, modified or silver-loaded processing |
| Packaging and logistics | 8% | 25 kg bag or ton bag, palletisation and terms at your destination port |
| Sample turnaround | 10% | Production-lot sample at the mesh and iodine value you intend to buy |
| Regeneration support | 8% | Steam regeneration data: 350–450 °C, 80–85% capacity recovery, 5–8 cycles |
Commercial terms
The line is stated as customizable according to customer requirements, with mesh options from 1–2 mm and 2–4 mm granules through 4–8, 6–12, 8–16, 8–30 and 20–40 mesh up to 200 mesh powder, and iodine grades of 600, 800, 900 and 1000 mg/g.
Standard packing is 25 kg/bag or ton bag. Confirm bag type, palletisation and whether you need the load split across mixed mesh grades.
Fruit shell carbon can be pickled, water-washed, modified and silver-loaded. Name the treatment in the RFQ — it changes the process route, not just the label.
Ask for the batch figures behind iodine value, mechanical strength and bulk density, the food-grade compliance reference for drinking water and food projects, and a packing list against your destination port.
Scenario to specification
Use this as the starting line of your RFQ rather than the finish. Starting points follow the published applications of each model; the mesh and iodine value still need confirming against your own bed or press.
| Your duty | Published starting point | Confirm before ordering |
|---|---|---|
| Removing residual chlorine, taste and odour at a water plant | Granular 12–24 mesh packed bed | Backwash intensity 10–15 L/(m²·s) and strength ≥94% |
| Point-of-use or household purifier cartridge | 24–48 mesh fine granular | Cartridge throughput target of 2–5 m³ and mesh fit to your filler |
| Boiler, condensed water or semiconductor high-purity loop | 10–24 mesh at a higher iodine value | Fines tolerance in the loop and the strength your bed allows |
| Sugar or syrup decolorization | Powder 150–325 mesh | Dosage in the 0.2–0.4% range and whiteness target above 92% |
| Wine, fruit juice or tea clarification | 20–40 mesh for packed beds | Whether you need decolorization, de-bittering or both |
| Aquaculture or tertiary sewage polishing | Granular 8–30 mesh | Steam regeneration or single-use cycles — regeneration recovers 80–85% of capacity across 5–8 cycles |
Request for quotation
The fastest quotations come from requests that already contain the duty, the specification and the commercial frame. Send these three blocks and a supplier can quote a specific batch instead of a range.
Name the use case — drinking water, ultra-pure and industrial water, food and beverage, aquaculture — plus your flow rate or bed volume and the contaminant you are targeting.
State mesh or particle size, iodine value, form (granular or powder) and any custom treatment: pickled, water-washed, modified or silver-loaded.
Give first-order and annual volume, packaging preference (25 kg bag or ton bag), destination port, required documentation and the date you need the production-lot sample in hand.
Send your duty, specification and volume together and ask for a production-lot sample quotation.
