Product Water Treatment

Polyaluminum Chloride (PAC)

High-performance inorganic polymer coagulant for clarification and turbidity reduction in drinking water, wastewater, and industrial process water. Designed for fast floc formation, broad operating tolerance, and repeatable performance for continuous procurement.

Formats: liquid or powder (grade-dependent)
Packaging: bags / drums / IBC / bulk (as applicable)
Documentation: SDS / COA / TDS on request
Lead time depends on lane, origin, and volume

Commercial overview

PAC is a widely used coagulant for municipal and industrial water treatment because it can reduce turbidity quickly, improve settling/filtration, and support stable operation across variable raw-water conditions.

Why buyers choose PAC

Strong clarification efficiency, often lower dose vs. conventional alum (case-dependent), and reliable floc formation for continuous operation.

Procurement-friendly

Multiple grades and packaging options for repeat orders. We align concentration, basicity, and impurity limits to your spec and provide COA/SDS/TDS with each lane.

Applications fit

Drinking water clarification, wastewater turbidity reduction, and industrial process water treatment where consistent suspended solids removal is needed.

Note: performance depends on raw water chemistry (alkalinity, organics), temperature, mixing energy, and downstream solids separation. Jar testing is recommended to finalize dosing and polymer aid selection.

Applications

Typical usage patterns and where PAC is commonly specified. Tell us your process and constraints and we’ll align the right grade.

  • Drinking water clarification (turbidity, color reduction support)
  • Wastewater turbidity reduction (primary/tertiary treatment support)
  • Industrial process water (make-up water, recycling loops, pretreatment)
  • Sludge dewatering support (as part of a coagulant + polymer program)
  • Phosphate removal programs (often paired with optimized pH and solids separation)

Technical guidance

Use this as an engineering starting point for trials. Final operating conditions should be confirmed in jar testing and commissioning.

Quality & documentation

Dosage (trial starting range)

Start with an incremental jar-test range (example: low-to-high steps) and optimize for turbidity removal, floc strength, and sludge volume. Actual dosing is site-specific and may vary widely by influent chemistry.

Tip: test with and without a polymer aid to optimize settling/filtration run-time.

Mixing & contact time

Apply rapid mixing for immediate dispersion, then gentle mixing for floc growth. Over-shearing can break flocs and reduce settling. Validate mixing energy in your flocculator/pipework.

pH & alkalinity

PAC is often used across a broader operating range than some conventional coagulants, but raw-water alkalinity and target pH still influence performance. If pH correction is required, define it as part of the chemical program.

Feed preparation

Liquid grades are dosed via metering pumps. Powder grades typically require dissolution and aging per site SOP. Use compatible wetted materials and keep lines flushed to prevent deposits.

Downstream separation

Clarifiers, DAF units, and filtration all respond differently to coagulant selection. Optimize for stable solids removal, filter headloss, and sludge handling based on your unit operations.

Compatibility & handling

PAC is typically acidic/corrosive. Specify storage and dosing equipment compatible with acidic inorganic coagulants. Always follow SDS guidance for PPE and safe handling.

Typical specifications & formats

Values depend on grade and customer requirements. Use these ranges for initial alignment; confirm the exact specification on quotation and COA.

Quality & documentation

Forms supplied

Liquid PAC for direct dosing programs; powder PAC for customers that prefer lower freight cost per active content or on-site dissolution.

Active content (grade-dependent)

Al content and basicity are tuned per application (drinking water / wastewater / industrial). We align to your target performance and any impurity/insoluble limits.

Packaging

25 kg bags / big bags (powder) • drums / IBC / bulk (liquid)

Documentation pack

SDS + COA standard on request • TDS and packing list available • label support for shipments

Performance notes

Rapid floc formation and clarification efficiency are commonly cited advantages; final results depend on water matrix and unit operations.

Quality options

Treatment-grade options available; if you have a tender spec, share it and we will match the closest compliant grade and origin.

Typical range guide (illustrative)

Final values depend on supplier grade and are confirmed on the COA for each batch.

Parameter Liquid PAC (typical) Powder PAC (typical) Notes
Appearance Yellowish to amber liquid Light yellow powder/granules May vary by iron/impurities and grade
Al2O3 (w/w) ~10–18% ~28–31% Specify your target active content
Basicity ~40–70% ~40–70% Higher basicity can influence pH impact and floc behavior
pH (1% solution) ~3.5–5.0 ~3.5–5.0 Confirm with TDS/COA
Insolubles ≤0.1% (typical) ≤0.3% (typical) Tighter limits available per grade
Packaging Drums / IBC / bulk 25 kg bags / big bags Select for your receiving and storage capability
Important
If your project is drinking water, share any regulatory/tender limits so we can propose the most appropriate grade and documentation set.

Specifications may vary depending on batch, origin, and packaging selection.

Supply, logistics & commercial terms

We coordinate PAC supply as a repeat procurement lane: consistent grade matching, documentation readiness, packaging alignment, and shipment coordination to your destination.

  • Common shipment options: EXW / FOB / CFR / CIF (as agreed)
  • Sampling: reference samples or pre-shipment samples (per lane)
  • Quality pack: SDS + COA; TDS and labels on request
  • Packaging customization: palletization, liners, labeling (volume-dependent)
  • Consolidation: combine lanes when it improves landed cost

MOQ & lead time

MOQ and lead time vary by origin, concentration, and packaging. Share your target volume and delivery window for an accurate offer.

Stability & storage

Store sealed in a cool, dry area. Protect from contamination and extreme temperatures. Typical shelf-life is grade-dependent and specified on documentation.

Receiving checklist

Verify packaging integrity, batch/lot labels, and COA alignment to your spec. For liquid, confirm density and appearance; for powder, confirm moisture and free-flowing condition.

FAQ

Quick answers buyers typically ask before trials or repeat procurement.

Liquid vs. powder: which should I choose?

Liquid is simplest for dosing and reduces on-site preparation. Powder can reduce freight per active content and may fit sites that already have make-down systems. Choose based on your equipment, receiving constraints, and total landed cost.

Will PAC change pH?

Like many coagulants, PAC can influence pH depending on alkalinity and dose. In many cases it is used successfully without major correction, but final behavior is water-matrix dependent—confirm via jar testing.

Do you provide COA and SDS?

Yes—SDS and COA are available on request, and we can provide a TDS and packing documentation set for procurement, receiving, and audit readiness.

Can it be used with polymer aids?

Often yes. A polymer aid may improve floc strength, settling speed, and filtration run time—especially under high turbidity or variable influent conditions. Dose optimization should be done in jar tests.

What packaging is available?

Powder: 25 kg bags and big bags (lane-dependent). Liquid: drums and IBC, and bulk deliveries where applicable. Tell us your unloading and storage limitations.

How do you quote?

We quote based on grade (Al2O3/basicity), form (liquid/powder), packaging, volume, destination, and documentation requirements. This helps avoid mismatched offers and shortens the procurement cycle.
