Should I choose coal‑based or coconut shell GAC?

Coal‑based GAC costs 30‑50% less and has a stronger mesopore structure, making it ideal for large‑scale industrial water treatment. Coconut shell GAC offers higher hardness (≥98%) and lower ash (<3%) for drinking water and high‑value applications. For budget‑sensitive, high‑volume projects, coal‑based is the recommended choice.

How long does a 1100 iodine GAC bed last?

Typically 1‑3 years for drinking water and 6‑12 months for industrial wastewater, depending on influent contaminant load. Monitor effluent quality and replace before breakthrough.

Which mesh size should I choose for coal‑based granular activated carbon?

8×30 mesh is the most versatile for general water treatment. Coarser sizes suit high‑flow, low‑pressure‑drop filtration; 12×40 or 30×60 mesh suits applications requiring high contact area and fine filtration.

Do I need pre‑treat new GAC before filling?

For water‑phase applications, soak and rinse with clean water to wash off surface fine powder, preventing blockage of filter tank and downstream pipelines. For gas‑phase systems, GAC can be loaded directly without pre‑washing.

How to get samples? What is MOQ for coal‑based GAC?

Free samples are available; freight cost shall be borne by buyer. Minimum order quantity is 1 ton for trial runs for process validation.

Can coal‑based granular activated carbon be acid‑washed or impregnated?

Yes. Acid washing reduces ash to below 3% and adjusts pH to neutral. Impregnation with KOH, iodine, or sulfur enhances targeted removal of gases such as H₂S and mercury vapor.

Can spent coal‑based GAC be thermally regenerated?

Yes. Thermal regeneration at 800‑900°C restores 85‑95% of adsorption capacity, typically for 3‑5 cycles. For small systems, direct replacement is often more economical.

What payment terms do you accept for bulk activated carbon orders?

T/T (30% deposit, balance against B/L copy) and L/C for bulk orders; T/T and PayPal for sample orders.

Coal-based granular activated carbon (GAC) in various sizes

Commoda Clavia

High iodine number — stronger adsorption

With an iodine number up to 1100 mg/g and surface area up to 1200 m²/g, this GAC delivers significantly higher adsorption capacity for chlorine, organics, odors, and trace contaminants than standard 600–800 iodine products — meaning longer bed life and lower cost per ton of water treated.

Low ash — cleaner effluent

Ash content controlled at 8% or below (≤12% standard, ≤3% acid-washed), preventing carbon fines from raising effluent turbidity — critical for drinking water and high-purity water systems.

High hardness — lower operational loss

Hardness ≥95% resists abrasion and breakage during backwashing and bed loading, keeping pressure drop stable and reducing carbon makeup consumption.

Full mesh range — in stock

Standard 8×30, 12×40, and 30×60 mesh available from stock. Custom sizes such as 50×80 mesh can be produced to match your flow rate, contact time, and pressure-drop requirements.

Structura pororum aequilibrata — applicabilitas late diffusa

Micropori aequilibrati (moleculae parvae) et mesopori (moleculae organicae magnae) permittunt eliminationem efficacem materiae organicae naturalis (NOM), residuorum pesticidarum et compostorum odoriferorum.

Quaestiones Frequenter Rogatae

Q1: Utrum carbones activati ex carbone minerali an ex testa cocos eligere debeam?

Carbon activatus ex carbone minerali pretium 30–50% minus habet et structuram mesoporosam fortioris, ideo idoneus est ad tractationem aquae industrialis magnae scalae. Carbon activatus ex testa cocos dura (≥98%) et cinerem minorem (<3%) praebet, ergo aptus est ad aquam potabilem et applicationes de alto valoris. Pro proiectis sensibilibus ad pretium et magni voluminis, carbon ex carbone minerali optio praecipua est.

Q2: Quam diu durat lectus carbonis activati cum indice iodi 1100?

Typice 1–3 annos pro aqua potabili et 6–12 menses pro effluenti industriali, secundum onus contaminantium in influente. Qualitatem effluentis observa et carbonem ante punctum breakthrough substitue.

Q3: Quam magnitudinem reticuli eligere debeo?

reticulum 8×30 est maxime versatilis pro communibus applicationibus tractationis aquae. Reticula crassiora pro filtratione alti fluxus et minimi decrementi pressionis idonea sunt; reticula 12×40 aut 30×60 pro applicationibus quae magnam superficiem contactus et finem filtrationem postulant.

Q4: Necesse estne praetractare novum carbonem activatum antequam in vas infundatur?

A: Pro applicationes in phase aquosa, immersere et lavare cum aqua pura ut pulverem finem superficialem auferas, impedens obstruptionem tanki filtrantis et tuborum post filtros. Pro systematibus in phase gaseosa, GAC directe imponi potest sine praevia lavatione.

Q5: Quomodo exemplaria obtinere possumus? Quae est MOQ?

A: Exemplaria gratuita disponibilia sunt; onus fructus ab emptore sustinendum est. Quantitas minima ordinis est 1 tonna pro experimentis ad conformationem processus.

Q6: Quod est MOQ?

1 tonna pro ordinibus experimentalibus. Pretia volumina pro magnis ordinibus disponibilia.

Q7: Potestne carbo lavari acido vel impregnari?

Ita. Lavatio acida cinerem ad minus quam 3% reducit et pH ad neutrum regit. Impregnatio per KOH, iodinum aut sulfur emendat eliminationem specificam gasorum ut H₂S et vapor mercurii.

Q8: Potestne GAC exhausta regenerari?

Ita. Regeneratio thermalis ad 800–900°C capacitatem adsorptionis ad 85–95% restituit, saepe pro 3–5 cyclis. Pro systematibus parvis substitutio directa saepius aequius pretium habet.

Q9: Quae condiciones solutionis accipitis?

T/T (30% depositum, reliquum contra copiam B/L) et L/C pro ordinibus magnis; T/T et PayPal pro ordinibus exemplarium.
