Application
* Water effluent treatment system It's used for purification of drinking water and wastewater treatment by settling
of impurities by means of precipitation and flocculation.
* 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.
* Textile Industry It used for color fixing in Naphthol based dyes for cotton fabric.
* Other Uses Leather tanning, lubricating compositions, fire retardants; decolorizing agent in petroleum, deodorizer;
food additive; firming agent; dyeing mordant; foaming gent in firefighting foams; fireproofing cloth; catalyst; pH control;
waterproofing concrete; aluminum compounds, zeolites etc.
