What we supply

Poly Aluminium Chloride in bulk, against a written specification.

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.

Applications

Where poly aluminium chloride earns its place.

Municipal water

Primary coagulant for potable water clarification.

Effluent treatment

Coagulation ahead of clarification in ETPs and CETPs.

Textile effluent

Colour and COD removal from dye-house discharge.

Pulp & paper

Retention and drainage aid on the paper machine.

Industrial water

Turbidity removal ahead of RO and process use.

Sludge treatment

Conditioning ahead of de-watering.

Handling & storage

What to get right before the load arrives.

Site notes

  • Liquid PAC is acidic and corrosive to metals — store in HDPE or FRP, never mild steel. The powder is far less troublesome to store but must be kept dry, because it is hygroscopic and will cake.
  • Dilute the powder properly before dosing. Under-dissolved PAC dosed as a slurry gives poor floc and blocks dosing lines, and the plant then wrongly concludes the chemical is weak.
  • Transport classification depends on the grade. Most water-treatment PAC — the powder and the higher-basicity liquid — is not regulated, which makes it simpler to move than the mineral acids. Low-basicity and high-strength liquid grades run acidic enough to be classified UN 3264, Class 8. Work from the safety data sheet for the specific grade being shipped rather than assuming. Standard chemical PPE at the dosing point.

Price

What actually moves the poly aluminium chloride 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

Poly Aluminium Chloride — what buyers ask us.

Is PAC better than alum?

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 or powder?

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.

What dose should I use?

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.

What is the poly aluminium chloride price?

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.

Do you supply PAC powder?

Yes — 30% PAC powder in 25 kg bags, as well as 10% and 17% liquid by tanker.

What is the HSN code for poly aluminium chloride (PAC)?

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.
