Sourcing Aluminum Sulfate (Non-Ferric Alum)? ChemicalDekho connects you with major domestic manufacturers like Grasim and diverse specialized producers. Access high-efficiency coagulants for municipal water and paper industries.
Aluminum Sulfate (CAS 10043-01-3) is the workhorse of water clarification. It destabilizes suspended particles, allowing them to clump and settle out. In the paper industry, 'Non-Ferric' Alum is critical for sizing to improve ink resistance. Listings cover Lumps (for slow dissolution) and Kibbled/Powder forms for automated dosing.
The platform distinguishes between Ferric Alum (cheaper, containing iron) and Non-Ferric Alum (pure white, iron-free <0.01%) to suit your technical needs.

Causes serious eye irritation. May be corrosive to metals. Acidic solution (pH ~3). Dust may irritate respiratory tract.
Non-Ferric is pure white and 'iron-free' (<0.01% Fe). It is required for drinking water and white paper to prevent staining. Ferric Alum is yellow/grey and used for wastewater where iron content doesn't matter.
It acts as a 'flocculant'. It binds to fine dirt particles that the filter misses, creating large 'flocs' that settle to the bottom for vacuuming.
Phitkari is usually Potassium Alum. Aluminum Sulfate is 'Filter Alum'. They are both alums and coagulants, but Aluminum Sulfate is more common for large-scale industrial water treatment.
It acidifies the soil. Gardeners use it to turn Hydrangeas blue (they turn pink in alkaline soil).
