Product Overview
Buy PAC powder 28–30% Al₂O₃ and liquid PAC from Drashti Chemicals, Vadodara — 25 kg HDPE bags, COA + MSDS, jar-test support, and WhatsApp bulk quotes within 4 business hours. Poly Aluminium Chloride (PAC, CAS 1327-41-9) is a pre-hydrolysed inorganic polymer coagulant — formula [Al₂(OH)ₙCl₆₋ₙ]ₙ — supplied as powder (~28–30% Al₂O₃) and liquid (10–18% Al₂O₃). Basicity in the 40–70% range handles high-turbidity textile and dye-house influent without the sludge volume spike typical of alum at equivalent dose. Request COA showing Al₂O₃ content and basicity before locking your annual tender — batch consistency matters more than headline purity on the label.
Grade selection hinges on your raw-water alkalinity and target effluent TSS. Low-basicity PAC (30–40%) works when pH is already elevated; mid-basicity (45–55%) covers most Gujarat municipal and industrial mixed effluent. High-basicity PAC (60%+) suits cold-season operation and low-alkalinity streams where alum would demand excessive lime correction. Drashti stocks multiple basicity bands — share your jar-test data and we match the right powder grade rather than pushing a single SKU.
Dosing typically runs 50–200 mg/L as product for primary clarification, but jar tests on your actual composite sample remain mandatory. Dissolve powder PAC in a 2–5% stock solution using a dedicated day tank with mechanical agitation; undissolved lumps pass through screens and foul DAF nozzles. Meter the stock solution via diaphragm pump into the flash-mix zone — never dose dry powder directly into a pipeline. Drashti provides dosing guidance with every bulk dispatch.
Packaging: 25 kg laminated HDPE bags, 50 kg drums, and 1 MT jumbo bags for plants consuming above 5 MT/month. MOQ starts at one pallet; bulk quote on request for tanker-adjacent powder silo refill programs across Anand, Bharuch, and Vapi industrial belts. MSDS and COA ship with each lot. GST invoice under 24AGLPC6288M1ZX. Same-day dispatch from Vadodara warehouse for standing PO accounts.
Choose PAC powder over liquid alum when freight distance exceeds 200 km or when your storage area lacks bunded liquid tanks. PAC also wins against ferric chloride where colour removal is secondary and sludge disposal cost per kg is tracked — PAC sludge dewaters faster in belt presses common at Gujarat textile ETPs. Switch to ferric only when sulfide, phosphate, or heavy-metal precipitation is the primary objective alongside turbidity reduction.

PAC Grades We Supply
Drashti Chemicals stocks powder and liquid Poly Aluminium Chloride (CAS 1327-41-9) matched to your Al₂O₃ and basicity requirement — the same grade bands Indian ETP and municipal buyers specify on tender COAs.
Powder PAC 30 — Medium Basicity
~29% Al₂O₃ (±1%), basicity ~40% (±5%). Yellow powder in 25/50 kg HDPE bags. Best for general ETP primary clarification and plants upgrading from alum.
Powder PAC 30 — High Basicity
~29% Al₂O₃ (±1%), basicity ≥64%. Higher charge density for cold / low-alkalinity raw water and high-colour textile effluent with lower sludge volume.
Liquid PAC 10 / 14 / 18
10–18% Al₂O₃ liquid grades for pump-and-dose systems. Supplied in HDPE carboys, drums or bulk tanker. Ideal when automated dosing and fast response matter more than powder storage.

Frequently Asked Questions
Is PAC powder 28–30% in stock in Vadodara?
Yes. Drashti Chemicals stocks PAC powder 28–30% Al2O3 at our Vadsar, Vadodara warehouse. Typical dispatch is 24–48 hours to Gujarat GIDC estates (Makarpura, Savli, Halol, Waghodia, Nandesari) with batch COA and MSDS.
What is the full form of PAC powder?
PAC full form is Poly Aluminium Chloride (also written polyaluminum chloride). It is an inorganic polymer coagulant used in ETP, STP and drinking-water clarification. Industrial powder grades are typically 28–30% Al₂O₃.
What is the chemical formula of PAC?
PAC is commonly written as [Al₂(OH)ₙCl₆₋ₙ]ₙ. Buyers should confirm Al₂O₃ % and basicity on the batch COA — powder and liquid grades are not interchangeable kg-for-kg.
What is the HSN code for PAC powder?
PAC powder is classified under HSN 28273200. The same code is used on GST invoices and export documents. Confirm on the commercial invoice for your shipment.
What pack sizes are available for PAC powder?
25 kg HDPE bags, 50 kg bags, and 1 MT jumbo bags. Minimum order is 25 kg. Mixed truck loads with polyelectrolyte, alum or caustic are available.
Do you provide batch COA and MSDS with PAC?
Yes. Every lot ships with batch COA and MSDS. Sample COA can be shared on WhatsApp before you raise the PO.
What is the CAS number for PAC powder?
Poly aluminium chloride (PAC) powder is CAS 1327-41-9, typically 28–30% Al₂O₃ for industrial ETP and municipal water treatment.
PAC vs alum — which should I buy for ETP?
PAC often needs a lower dose and produces less sludge than alum on coloured textile effluent, but jar tests decide. Drashti stocks both PAC and alum in Vadodara so you can trial either grade with COA.
PAC vs ferric chloride — which coagulant for colour or phosphate?
Ferric chloride is usually stronger on phosphate and some dye colours; PAC is usually the better daily coagulant when sludge volume and chloride TDS matter. Many plants stock both. See PAC vs Ferric Chloride, then WhatsApp your inlet notes.
How should PAC powder be stored?
Keep bags dry and off the floor. PAC powder is hygroscopic and cakes in monsoon sheds. Use 25/50 kg laminated bags, first-in-first-out, and dissolve to a stock solution — do not dose undissolved lumps.
