Karbon Aktif Bubuk (PAC)
Wood-based, coal-based, coconut-shell and fruit-shell PAC options for rapid-contact liquid treatment and downstream separation.
Types of Powdered Activated Carbon
Coconut Shell Powdered Activated Carbon
View details
Coconut-shell PAC can be assessed for polishing process water and liquid streams where small-particle dosing, mixing and carbon removal are already built into the treatment train. Compare the finished grade on the actual feed before selecting a bulk supply specification.
Best for:
- Process-water polishing
- Taste and odor treatment trials
- Batch liquid purification
Coal-Based Powdered Activated Carbon
View details
Coal-based PAC is an option for wastewater treatment and industrial purification where dose, contact time and overall treatment cost need to be compared together. A controlled jar test helps establish the required dose and the downstream separation load.
Best for:
- Municipal wastewater treatment
- Industrial wastewater treatment
- Chemical process-liquid trials
Wood-Based Powdered Activated Carbon
View details
Wood-based PAC is commonly evaluated for color removal from process liquids. The selection should follow a real-feed decolorization trial, with attention to filtration behavior, ash and any limits required for the intended use.
Best for:
- Sugar and syrup decolorization trials
- Food and beverage process liquids, subject to grade approval
- Industrial liquid color removal
Fruit Shell Powdered Activated Carbon
View details
Fruit-shell PAC provides another raw-material option for liquid-treatment buyers. Specify the shell source where required and compare removal performance, dose and filtration under the same test conditions as other candidate carbons.
Best for:
- Alternative-feedstock procurement
- Water-treatment dosing trials
- Batch purification with downstream filtration
What Is Powdered Activated Carbon (PAC)?
Powdered activated carbon (PAC) is dosed into a liquid or process stream when rapid contact is useful and the spent carbon can be removed afterward. Raw material and processing determine which contaminants a grade handles best; particle size alone is not enough.
Purchasing Summary
| Buying brief | Share the application, required grade, particle size and acceptance tests. |
|---|---|
| Documents and packing | Identify the test report, destination-market requirements, packing and labeling needed for your order. |
| Order details | Confirm sample quantity, bulk quantity, destination and required delivery date. |
For PAC orders, state the treatment duty, target particle size, daily consumption and delivery quantity. Include bag handling and dosing requirements when requesting packing options.
Where Powdered Activated Carbon Fits in Rapid Purification
PAC disperses through the treatment volume and can be adjusted as water quality or batch conditions change. It is useful when a facility has mixing, contact and solids-separation stages. Dose, contact time and removal efficiency should be determined by trials on the real feed.
Powdered Activated Carbon (PAC) Applications
Rapid liquid treatment and decolorization
Powdered activated carbon is mixed directly with liquids to bring fine particles into contact with dissolved compounds. Water treatment, sugar solutions and process-liquid decolorization use different acceptance tests.
Batch and continuous dosing systems
PAC may be introduced into a batch tank or a designed dosing stage. Select a grade by removal targets and filterability, then validate contact time and downstream carbon separation.
Pertanyaan yang Sering Diajukan
Where is PAC used?
PAC is evaluated for water-treatment dosing, liquid decolorization and process purification where the carbon can be mixed and later separated.
How is the correct PAC dose established?
Use representative jar or process trials at planned contact time and temperature. Measure removal and downstream separation instead of assuming one universal dose.
Which raw material is best for PAC decolorization?
Wood and fruit-shell candidates may be useful for color trials; coal and coconut-shell grades suit other objectives. Compare finished grades using the same liquid.
Can PAC be loaded directly into a GAC filter?
A fixed granular bed and a powder-dosing process have different designs. Do not substitute powder without a suitable dosing and solids-removal stage.
What matters besides PAC mesh?
Review particle-size distribution, adsorption performance, ash, pH, moisture and filterability. Apply impurity limits appropriate to the intended liquid.
What should a powdered-carbon quotation include?
Send the feed liquid, target compound or color, treatment volume, contact time, temperature, separation method and required documents.
