Tell us your target issue (taste/odor, color, TOC, specific organics) and unit process; we’ll align a grade and a trial plan that leads to stable operating cost.
What PAC does in treatment trains
Powdered activated carbon is an adsorbent added directly to water to remove dissolved organic compounds and nuisance contaminants (taste/odor compounds, color bodies, TOC fractions, and various organic micropollutants). PAC is typically dosed as a slurry and then removed with clarification/filtration (e.g., coagulation + sedimentation + filters, DAF, membrane pretreatment).
Broad-spectrum adsorption
Targets many dissolved organics; performance depends on pore structure and contact time.
Infrastructure-friendly
Adds adsorption capability without installing fixed-bed vessels (process dependent).
PAC vs GAC (practical guidance)
Choose the operating strategy that matches your plant.
- PAC: flexible dosing, good for seasonal/events, removed with solids separation
- GAC: fixed beds for continuous polishing, higher capital but steady performance
- PAC often supports upstream control; GAC often supports final polishing
If you share your contact time and where you can dose (rapid mix, floc basin, filter), we’ll recommend which strategy is better and why.
Applications
Typical usage patterns. Tell us your process and constraints and we’ll align the right grade (base material + pore structure + PSD).
- Taste & odor control (seasonal algae-related compounds, raw water events)
- TOC and UV254 reduction (organic load management; process dependent)
- Color removal and trace organic adsorption
- Industrial wastewater polishing (select organics; trial verified)
- Membrane pretreatment support where organics drive fouling (case dependent)
How PAC is typically used
A practical view of dosing and removal (plant specific).
Dose point
Often added at rapid mix or upstream of flocculation to increase contact time before separation.
Contact time
More contact improves adsorption. PAC can work with minutes to hours depending on target compounds.
Removal
Removed with floc/solids via clarifier/DAF and captured on filters (or equivalent separation).
We can support a jar-test plan: dose range, mixing protocol, and target KPIs (TOC/UV254, color, odor panel, or specific analytes).

Technical selection guide (quick)
Choose the grade that matches your target compounds and unit operations.
Micropollutants / taste-odor
Higher micropore capacity often correlates with higher iodine number (confirm by trials).
Color / larger organics
Mesopore development is often reflected in methylene blue or related indicators (confirm by trials).
Plant handling
PSD influences wetting, slurry stability, dusting, filter loading, and adsorption kinetics.
Handling, slurry prep & storage
PAC is typically prepared as a slurry for dosing. Good wetting and consistent mixing reduce floating carbon, improve dose accuracy, and stabilize performance. Handling should follow SDS guidance, especially for dust control and housekeeping.
Slurry prep
Use clean water, controlled addition, and adequate agitation to wet PAC and prevent clumping.
Feed strategy
Dose where you can maximize contact time and ensure capture downstream (clarifier/filters).
Storage
Keep dry, sealed, and away from strong oxidizers; follow SDS for safe storage and PPE.
Common troubleshooting
Fast fixes for typical PAC issues.
- Floaters / poor wetting: improve wetting sequence, mixing energy, or use a different PSD
- High filter loading: adjust PSD/dose point, optimize coagulation/flocculation, verify capture
- Inconsistent removal: confirm contact time, dose control, and raw water variability
- Dust issues: improve handling, sealed transfer, and housekeeping per SDS
FAQ
Quick answers for operations, engineering, and procurement.
What specs should we specify in procurement?
Common specs include iodine, methylene blue (or equivalent), moisture, ash, PSD/mesh, bulk density, and documentation requirements.
Will PAC affect turbidity or filters?
PAC can increase solids loading; performance depends on dose, PSD, dose point, and downstream capture/filtration.
How do we choose base material?
Coal/wood/coconut grades differ in pore structure. The best match depends on your target compounds and contact time—verify by trials.
Is PAC used continuously?
Yes, it can be continuous or event-based. Many plants use PAC seasonally for odor episodes or raw-water events.
What documentation do you provide?
SDS and TDS are available on request. COA availability depends on grade and lane.
How do we start without over-spending?
Start with a controlled dose range and measure KPI improvement vs dose; choose the grade/PSD that hits targets at the lowest stable dose.
