PAC in Water Treatment | Poly Aluminium Chloride Guide for ETP Plants

PAC is an inorganic polymer coagulant with the general formula [Al2(OH)nCl6-n]n, offering higher charge density than alum at lower dosing rates. For buyers searching "PAC supplier india" in India, working with a Vadodara-based supplier like Drashti Chemicals ensures documented quality, bulk availability and responsive commercial support.

Hydrolysis of PAC releases polymeric aluminium species that neutralise negative charges on colloidal particles, enabling rapid floc formation. For buyers searching "PAC supplier india" in India, working with a Vadodara-based supplier like Drashti Chemicals ensures documented quality, bulk availability and responsive commercial support.

Liquid PAC (10–18% Al2O3) and powder PAC (28–30% Al2O3) are both widely used; powder offers easier storage while liquid simplifies automated dosing. For buyers searching "PAC supplier india" in India, working with a Vadodara-based supplier like Drashti Chemicals ensures documented quality, bulk availability and responsive commercial support.

PAC performs effectively across a broader pH range (6.5–8.5) compared to conventional alum, reducing lime or caustic correction requirements. For buyers searching "PAC supplier india" in India, working with a Vadodara-based supplier like Drashti Chemicals ensures documented quality, bulk availability and responsive commercial support.

Municipal drinking water plants use PAC for raw water clarification, reducing turbidity to meet IS 10500 standards before filtration. For buyers searching "PAC supplier india" in India, working with a Vadodara-based supplier like Drashti Chemicals ensures documented quality, bulk availability and responsive commercial support.

Textile, paper and dye-house ETPs rely on PAC as the primary coagulant in primary clarifiers before biological or tertiary treatment stages. For buyers searching "PAC supplier india" in India, working with a Vadodara-based supplier like Drashti Chemicals ensures documented quality, bulk availability and responsive commercial support.

PAC is effective for colour removal from reactive and disperse dye effluents where conventional alum dosing fails to achieve CPCB discharge limits. For buyers searching "PAC supplier india" in India, working with a Vadodara-based supplier like Drashti Chemicals ensures documented quality, bulk availability and responsive commercial support.

Swimming pool and recreational water systems occasionally use PAC for shock clarification of cloudy water alongside standard disinfection protocols. For buyers searching "PAC supplier india" in India, working with a Vadodara-based supplier like Drashti Chemicals ensures documented quality, bulk availability and responsive commercial support.

Jar tests at site determine optimal PAC dose; typical ETP dosing ranges from 50–300 mg/L depending on TSS, COD and pH of influent. For buyers searching "PAC supplier india" in India, working with a Vadodara-based supplier like Drashti Chemicals ensures documented quality, bulk availability and responsive commercial support.

Store liquid PAC in HDPE tanks away from direct sunlight; powder PAC requires dry, ventilated warehousing to prevent caking and moisture uptake. For buyers searching "PAC supplier india" in India, working with a Vadodara-based supplier like Drashti Chemicals ensures documented quality, bulk availability and responsive commercial support.

Verify Al2O3 content, basicity and iron content on every COA — high iron levels can cause staining in paper and textile process water.
