Powdered Activated Carbon
Powder activated carbon represents a finely ground form of activated carbon, characterised by its minute particle size. Typically, powder activated carbon particles measure below 0.2mm (200 microns), distinguishing them from the larger granules of granular activated carbon (GAC). This finely powdered state enhances its surface area, augmenting its adsorption efficiency and reaction kinetics, rendering it ideal for specific purification tasks.

Powdered Activated Carbon offers several benefits:
●PAC adsorbs micropollutants efficiently.
●It can be added during coagulation, forming larger flocs that settle faster.
●PAC reduces sludge volume and improves solid–liquid separation.
●PAC enhances taste and odor removal in treated water.
●PAC improves membrane performance and helps control biofouling.
●PAC provides cost advantages compared to some cleaning methods.
Applications of Powdered Activated Carbon:
●Treating drinking water (surface water during blooms or groundwater to reduce humic substances).
●Removing organic compounds, such as COD or AOX, in wastewater treatment.
●Decolorizing chemical and food products.
●Removing dioxins, furans, and mercury from gases generated during the thermal treatment of waste.
1.By Raw Material
●Coconut shell PAC – Best for small molecules (gold recovery, gas masks)
●Wood-based PAC – Ideal for decolorization (sugar, chemicals)
●Bamboo-based PAC – Cost-effective for wastewater
2. By Iodine Number (Adsorption Capacity)
●Low (400–600 mg/g) – Basic odor control
●High (900–1,100 mg/g) – Toxic chemical removal
3.By Application
●Drinking water – NSF/ANSI 61 certified
●Food-grade – FDA-compliant PAC
How to Use Powder Activated Carbon
Dosing
Typical range: 5–100 mg/L (varies by contaminant)
Mixing
Stir 15–30 minutes for maximum adsorption
Filtration
Remove PAC via settling, sand filters, or membranes
Packing&Delivery
