About Poly Aluminium Chloride (PAC)
Poly Aluminium Chloride PAC is an inorganic coagulant used to destabilise suspended solids and help form stronger flocs with lower dose variability compared with simpler aluminium salts in many setups. Buyers typically evaluate the grade type, concentration basis, basicity range, and how the product behaves with their raw water or paper process chemistry. COA, MSDS, and specification points can be shared on request during quotation, subject to availability.

Applications
Water treatment
- ♦PAC is used for clarification, where stable coagulation can reduce turbidity swings and improve settling or filtration consistency. Technical teams usually care about dose response, residual aluminium control targets, and how the grade behaves across raw water variability. Acceptance criteria can be aligned during quotation as per the buyer's specification.
Paper Mills
- ♦PAC is used in process water treatment and may be evaluated for performance impact on retention, drainage, and deposit control depending on the mill chemistry. Buyers typically focus on consistency, compatibility with existing polymers and wet end additives, and residue risk in the system. Grade selection can be discussed during quotation, subject to availability.
Safety & Handling
- ♦Follow the MSDS for the supplied batch and your site EHS procedures.
- ♦Avoid dust exposure for powder grades and avoid contact with eyes and skin for all grades.
- ♦Use appropriate gloves and eye protection, and maintain good housekeeping around dosing areas.
- ♦Store sealed in a dry, well-managed area for bags and in suitable closed tanks for bulk supply, away from incompatible chemicals as per MSDS.

Common Questions About Reaching Us
Pricing typically depends on grade type, concentration basis, quantity, delivery location, and current market movement. Use Get a Quote with your monthly requirement and packaging preference so pricing and availability can be confirmed during quotation, subject to availability.
Experts usually decide based on basicity and aluminium basis because performance can shift when raw water changes. Share your raw water range, temperature, and target turbidity with the best chemical supplier in India so a suitable grade option can be discussed during quotation, subject to availability.
Basicity influences hydrolysis behaviour and can change dose response, floc formation, and residual aluminium risk depending on raw water alkalinity. If you are optimising for stable turbidity removal, share your raw water profile and control targets. Grade alignment is discussed during quotation, subject to availability.
Choice usually depends on dosing infrastructure, handling preference, and how the grade interacts with your wet-end program. If your focus is retention, stability or deposit control, share your current chemistry and pain points. Suitable options can be discussed during quotation, subject to availability.
COA, MSDS, and specification details can be shared on request during quotation, subject to availability and internal process. SGS & Company is a chemical supply and distribution company based in Vadodara, and you can include your QA checklist and delivery location so the response aligns to your release needs.
Many QA teams align to aluminium content basis, basicity range, appearance, pH range, and insoluble matter, plus any impurity limits tied to process sensitivity. Share your acceptance limits and test method preference. What can be supported is confirmed during the quotation based on available batch documentation, subject to availability.
Compatibility depends on concentration, temperature, tank material, gasket type, and dosing pump design. Share your tank and line materials, seal types, and operating conditions. Practical guidance can be discussed during quotation as per MSDS and your site SOP, subject to availability.
