What we supply
PAC is the coagulant that has largely displaced alum in Indian water treatment, and for practical reasons: it works across a wider pH band, needs less alkalinity correction, produces less sludge and performs better in cold water. Plants that switch from alum usually find they dose less and de-water more easily.
Velora supplies both the liquid, normally around 10% Al₂O₃, and the spray-dried powder at around 30%, which is the sensible form when the plant is far from the source and paying freight on water makes no sense. A high-concentration 17% liquid grade is also available where a plant wants fewer tanker movements but still doses as a liquid.
Grades & packing
These are the formats we most commonly supply. Other grades, packing sizes and pack marking are available — ask at the enquiry stage.
| Product | Formula | Grade | HSN | Packing |
|---|---|---|---|---|
| Poly Aluminium Chloride | PAC | 10% & 17% liquid · 30% powder | 2827 32 00 | Road tanker · 25 kg bag |
No tested values are published here. The certificate of analysis for the batch actually loaded travels with the despatch documents, and a representative COA and the safety data sheet go out before any commercial discussion.
Applications
Primary coagulant for potable water clarification.
Coagulation ahead of clarification in ETPs and CETPs.
Colour and COD removal from dye-house discharge.
Retention and drainage aid on the paper machine.
Turbidity removal ahead of RO and process use.
Conditioning ahead of de-watering.
Handling & storage
Worth reading before you order rather than after. If any of this is a problem at your site, tell us — it usually changes what we would quote.
Price
PAC is made from aluminium hydroxide and hydrochloric acid, so it moves with both. The real commercial decision is liquid versus powder: 10% liquid is cheaper per tonne but is roughly 75–80% water, and the powder runs about three times its strength, so beyond a few hundred kilometres the powder usually lands cheaper per unit of Al₂O₃. Tell us your location and monthly tonnage and we will run that comparison for you.
Questions
For most water and effluent duty, yes — it works across a wider pH range, needs less alkalinity correction, generates less sludge and performs better in cold water. Alum is still cheaper per tonne, so for a plant with easy pH control and cheap sludge disposal it can still make sense. Compare on total cost, not on the drum price.
Liquid if you are close to the source and have bulk storage. Powder if you are far away, because you stop paying freight on water, or if you have no tank. Send us your delivery point and monthly quantity and we will tell you which one lands cheaper.
That has to come from a jar test on your actual water — it varies with turbidity, alkalinity, temperature and what else is in the stream. Anyone quoting you a dose without seeing the water is guessing.
PAC is quoted per kg or per tonne, landed. Powder costs more per kg than liquid but carries far more alumina and much less water, so compare on alumina content delivered, not on the headline rate.
Yes — 30% PAC powder in 25 kg bags, as well as 10% and 17% liquid by tanker.
The HSN code for poly aluminium chloride (PAC) is 2827 32 00 (Chlorides of aluminium). PAC is most commonly classified here in Indian trade; depending on the exact product it can also be argued under 2827 49 00 (chloride hydroxides) or, for a formulated coagulant, 3824 99 00. Confirm the heading with your own tax adviser. Source: the Indian customs tariff as listed in the GST HSN directory, checked September 2026.

| Representative COA | A producer’s representative certificate of analysis for the grade you specify, obtained at enquiry stage so your QC can assess poly aluminium chloride against your own specification | Before commercial terms |

We do not publish blank certificates to download. A certificate of analysis belongs to a batch, so a generic one tells you nothing about the material on your vehicle — and the safety data sheet is the producer’s document for the grade actually quoted. Ask and both are emailed, usually the same working day.
