Looking for a Jacobi AquaSorb alternative? Yihang Carbon's coal-based granular activated carbon matches AquaSorb 1000 and 2000 grade-for-grade — iodine up to 1100 mg/g, ash as low as 8%, hardness ≥95%, in 8×30, 12×40 and 30×60 mesh. Acid-washed grades available with ash ≤3%. This guide cross-references every AquaSorb coal grade to its Yihang equivalent, compares specs side by side, and explains test-method differences honestly. Factory-direct pricing, 1-ton trial orders, free samples, SGS-tested COA per batch, and export delivery in 3–15 days. Request a matched spec sheet and test sample within 24 hours.

Quick Answer
Yes — Yihang Carbon's coal-based granular activated carbon is a direct alternative to Jacobi's AquaSorb coal GAC line. Yihang's high-iodine coal GAC (iodine up to 1100 mg/g, ash ≤8–12%, hardness ≥95%) covers the performance band of AquaSorb 1000 (iodine ≥850 mg/g) and AquaSorb 2000 (iodine ≥1000 mg/g) at factory-direct pricing, with the same mesh cuts (8×30, 12×40, 20×50), 25 kg / 500 kg packaging, and third-party SGS testing. Jacobi's AquaSorb HS is coconut-shell based and acid-washed — for that duty, request Yihang's acid-washed grade (ash ≤3%).
1. An Honest Note Before the Comparison
One thing up front, in the interest of a fair comparison: Jacobi publishes full datasheets per grade, and its specs are legitimate and well-controlled. We are not claiming Yihang carbon is "better" — we are showing that it matches the published duty of each AquaSorb grade at a lower landed cost. Jacobi specs below come from its published technical datasheets; Yihang figures come from our published product page and SGS test reports. For any grade, request both TDS documents and compare line-by-line before switching volume.
2. Jacobi AquaSorb Grade → Yihang Carbon Cross-Reference Table
AquaSorb is Jacobi's flagship water-treatment GAC family — a deep line split by activity level, mesh, and washing treatment. The table below maps every major coal-based AquaSorb grade to its Yihang equivalent.

What we do not claim to match one-for-one:
AquaSorb HS is a coconut-shell carbon — a different raw material class from coal. If your specification mandates coconut shell with ≤1% ash (e.g., semiconductor or dialysis water), tell us your conductivity and silica limits and we will confirm whether our acid-washed grade fits, rather than stretching a match.
3. Head-to-Head: AquaSorb 2000 vs Yihang High-Iodine Coal GAC
AquaSorb 2000 is Jacobi's workhorse high-activity coal GAC and the grade most buyers ask us to match. The table below puts it side by side with the Yihang grade we recommend as its replacement. Jacobi figures are from its published datasheet
; Yihang figures are from our published specifications and SGS testing.

The same pattern holds one tier down: AquaSorb 1000 (iodine ≥850 mg/g, ash ≤15%
) is matched by Yihang's standard 850–900 iodine grade — with materially lower ash (8–12% vs ≤15%) at the same hardness floor.
4. Iodine, Ash, and Density — What the Numbers Mean in Practice
Iodine number is the proxy buyers use for micropore surface area. AquaSorb 1000's ≥850 mg/g floor makes it an "economy medium-activity" grade
; AquaSorb 2000 steps up to ≥1000 mg/g
. Yihang's coal GAC spans 600–1100 mg/g, so a single production line covers the full AquaSorb 1000→2000 duty range — you specify the iodine band, we produce to it, and the SGS-tested COA travels with every batch.
Ash is the spec that quietly drives operating cost. Jacobi allows up to 15% ash on AquaSorb 1000 and 13% on AquaSorb 2000
. Yihang's standard band is 8–12%, and acid washing takes it below 3%. Less ash means fewer fines, faster rinse-down after bed loading, and lower risk of post-filter turbidity spikes in drinking-water duty.
Apparent density matters for vessel sizing and freight. Both products sit in the 450–550 kg/m³ band, so bed volumes and container loading calculations carry over directly.
5. Mesh Sizes and Form — Drop-In Compatibility
Jacobi offers AquaSorb coal grades in 8×16, 8×30, 12×40, 20×50, and 6×12 mesh
. Yihang stocks 8×30, 12×40,40×80。and 30×60 mesh with 4×8 and custom cuts (including 50×80) available. For the standard 8×30 and 12×40 cuts used in most municipal and industrial vessels, replacement is a direct swap with no change to underdrain settings or backwash rates — though as with any carbon change, verify effective size and uniformity coefficient against your vessel design.
6. An Honest Note on Test Methods
Jacobi's datasheets state that specifications and typical properties are produced using Jacobi Carbons' own test methods, and that sales specifications should be confirmed with its technical sales team before ordering
. The same applies to us: iodine per ASTM D4607, hardness by ball-pan/GB methods, density per ASTM D2854. Where a number is business-critical (hardness for aggressive backwash regimes, effective size for dual-media beds), ask
both suppliers for results under the
same method — or run the two carbons side by side in your own column. That is the only comparison that cannot be argued with.
7. Cost and Supply — Why Yihang Is a Practical Alternative
Jacobi Carbons (part of Osaka Gas Chemicals) is a global premium brand; its pricing reflects the brand, its global reactivation network, and its quality infrastructure. That premium is justified for some procurement processes.
Yihang Carbon is positioned differently: comparable published performance at factory-direct pricing. For plants changing tens of tons per year, the per-ton difference compounds into a meaningful annual saving.
-
Factory-direct pricing — no distributor or brand markup; coal sourced at the mine gate.
-
1-ton trial orders accepted — validate the switch on one vessel before committing volume.
-
Free pre-purchase samples — run Yihang carbon against your current AquaSorb grade under identical conditions.
-
Fast, documented delivery — 5–10 tons ships in 3 days; 10–20 tons in 5–7 days; 30–50+ tons in 10–15 days; full export documentation (COA, raw-material report, sea-freight appraisal, business license).
-
Batch consistency — every shipment with COA and SGS-supported testing; OEM/custom packaging available.

Choose Yihang if you run AquaSorb 1000/2000 (or equivalent coal GAC) in municipal, industrial, or RO-pretreatment duty and want to cut media cost without changing vessels, mesh, or process parameters.
Stay with Jacobi if your tender explicitly names the brand, or your duty is coconut-shell-class (AquaSorb HS, ultrapure water) where raw material is part of the specification.
Either way, the definitive test is a side-by-side column run: same feed water, same EBCT, same bed depth. Request matched samples and decide on your own data.
Frequently Asked Questions
Which Jacobi AquaSorb grades does Yihang Carbon replace?
Yihang's coal-based GAC covers the full coal-based AquaSorb line: the 850–900 iodine grade replaces AquaSorb 1000; the 1000–1050 grade replaces AquaSorb 2000, 5000, and 6000-class duties; the up-to-1100 high-iodine grade matches AquaSorb 9000-class applications; and the acid-washed grade (ash ≤3%) replaces AquaSorb 7000-class duties. AquaSorb HS is coconut-shell based — a different raw material — so we assess that match case by case.
Is Yihang coal GAC a drop-in replacement for AquaSorb 2000?
For standard water-treatment duty at 8×30 or 12×40 mesh, yes — iodine, hardness, moisture, density, and pH all overlap. Verify effective size and uniformity coefficient against your vessel design, and run a short parallel column test before switching full volume.
How do the ash contents compare?
Jacobi specifies ≤15% (AquaSorb 1000) and ≤13% (AquaSorb 2000). Yihang's standard band is 8–12%, with ≤3% available via acid washing — lower ash reduces fines and rinse-down time after bed loading.
Does Yihang provide certifications and export documentation?
Every batch ships with a COA; SGS and ISO 9001-related testing and certification support are available. We provide raw-material test reports, factory business license, and sea-freight transport appraisal reports for export.
What is the MOQ, and can I test samples first?
MOQ is 1 ton for trial orders. Free samples are available before purchase (buyer covers freight), typically shipped within 3–5 days.
Can the carbon be acid-washed or impregnated like Jacobi's treated grades?
Yes — acid washing lowers ash below 3% and adjusts pH to 6–8; impregnation (KOH, iodine, sulfur) is available for targeted gas-phase removal such as H₂S.
How fast can you deliver export orders?
5–10 tons ships within 3 days; 10–20 tons within 5–7 days; 30–50+ tons within 10–15 days. Other quantities are confirmed in advance. Standard packaging is 25 kg PP woven bags or 500 kg jumbo bags on export pallets, stretch-wrapped; OEM branding is supported.
