APPLICATION
It’s used for purification of drinking water and wastewater treatment by settling of impurities by means of precipitation and
flocculation.
1. Paper Industry:
It helps in sizing of paper at neutral and alkaline pH, thus improving paper quality (reducing spots and holes and improving sheet formation and strength) and sizing efficiency.
2. Textile Industry :
It is used for color fixing in Naphthol based dyes for cotton fabric.
3. Other Uses:
Leather tanning, lubricating compositions, fire retardants; decolorizing agent in petroleum, deodorizer; food additive; firming agent; dyeing mordant; foaming agent in firefighting foams; fireproofing cloth; catalyst; pH control; waterproofing concrete; aluminum compounds, zeolites etc.
