What is Polyaluminum Chloride (PAC) for water treatment?
Polyaluminum chloride is a pre-polymerized aluminum coagulant family whose performance and identity depend on aluminum concentration, chloride content, basicity and physical form.
Selection depends on the exact commercial form, incoming-water chemistry, process objectives, treatment train, materials of construction, residual limits, operator controls and jurisdiction. This page supports procurement qualification and is not a dosing instruction.

Procurement checklist
How to source Polyaluminum Chloride (PAC) in bulk
Use these procurement questions when comparing a China supplier, manufacturer source, distributor, sample or bulk quotation.
Quotation and delivery basis
Compare source-specific specification, concentration basis, packing, transport classification, Incoterm and delivery.
Application and process requirements
Share water analysis, process objective, materials, operating envelope, discharge limits and validation plan.
Technical and quality documents
Request current SDS, specification or TDS, representative COA, batch COA, traceability and applicable certification.
Application screening
Polyaluminum Chloride (PAC) water-treatment application guide
These are technical screening areas—not universal approvals, operating directions, efficacy claims or guaranteed outcomes.
Drinking-water clarification where certified
Qualify the exact grade using representative source water. Compare settled and filtered turbidity, residual metal or polymer requirements and the applicable product certification; include seasonal water changes in the trial plan.
Municipal and industrial wastewater coagulation
Use samples that represent changes in suspended solids, pH and organic load. Compare clarification and downstream separation with the current treatment, and record sludge production as well as chemical consumption.
Turbidity and color-removal programs
Define whether the target is apparent color, dissolved color, turbidity or an organic-load measure. Compare results using the appropriate analytical method and verify performance after the plant's separation stage.
Phosphorus-removal treatment trains
Define the phosphorus target and the treatment stage before screening a grade. Measure phosphorus after the actual solids-separation step and assess pH, residual metal and additional sludge together.
Technical selection
Questions to resolve before approving Polyaluminum Chloride (PAC)
Liquid or powder and aluminum basis
Specify liquid or powder and state whether the assay is expressed as aluminum or Al2O3. Compare alternatives on the same supplied-product and active-content basis.
Basicity, chloride, density and insolubles
Evaluate basicity together with chloride content, density and insolubles. The best grade depends on the source water and process rather than on one isolated specification value.
Iron content and dissolution behavior
Request iron limits and assess dissolution for the offered powder or liquid grade. Check residue and preparation requirements against the site's feed system.
Jar testing, residual aluminum and certification
Use representative jar tests to compare clarity and residual aluminum through the treatment train. Require exact-grade certification where potable-water use is intended.
Private technical documentation
Request the current Polyaluminum Chloride (PAC) product specification
Bespring Chemical does not publish product specifications for this water-treatment chemical online. Contact sales for the current source-specific specification or TDS and confirm its revision, methods and acceptance criteria.
Product documents
Request the current signed specification or TDS, SDS, analytical methods, representative COA and batch COA.
Safety and logistics
Confirm classification, UN transport information where applicable, compatible packing, storage segregation, shelf life and emergency controls.
Authoritative context
Review US EPA drinking-water regulations, WHO Guidelines for Drinking-water Quality and NIH PubChem. Final approval depends on the exact product, water application and jurisdiction.
Water-use note: A raw-material identity does not establish potable-water approval, disinfectant efficacy or a safe universal dose. Treatment must be designed and validated from water data, monitored for relevant residuals and by-products, and operated under applicable product approvals and regulations.
Storage and handling
Handle Polyaluminum Chloride (PAC) under the current SDS
- Source instructionsFollow the current SDS and specification for temperature, ventilation, segregation and shelf life.
- IncompatibilitiesPrevent contact with incompatible chemicals, moisture, heat or contamination as identified for the exact product.
- Engineered controlsUse suitable closed handling, ventilation, containment, PPE, labeling and trained emergency procedures.
Water-treatment buyer questions
Polyaluminum Chloride (PAC) FAQ
What is Polyaluminum Chloride (PAC) used for in water treatment?
Polyaluminum chloride is a pre-polymerized aluminum coagulant family whose performance and identity depend on aluminum concentration, chloride content, basicity and physical form. Suitability must be established for the exact treatment system and intended water use.
Which Polyaluminum Chloride (PAC) identity should buyers specify?
Basic aluminum chloride polymer; common CAS 1327-41-9; Liquid or powder; basicity and Al basis required. State the exact commercial form, concentration, grade and source-specific requirements.
Why is there no public specification?
Bespring Chemical does not publish specifications for this water-treatment chemical online. Contact sales for the current source-specific specification or TDS, methods and representative COA.
Can Polyaluminum Chloride (PAC) be used for drinking-water treatment?
Only where the exact product is approved or certified for that application and the treatment is designed, validated, monitored and operated under applicable rules. This raw-material page does not establish potable-water approval.
What should the RFQ include?
Provide the exact identity, form or concentration, water application, source-water or system data, critical limits, quantity, packing, destination, documents, Incoterm and delivery date.
