Application:

Spent Acid is mainly used for manufacture of various fertilizers like SSP (Single Super Phosphate), DCP (Di Calcium Phosphate)
It is used in manufacturing of various Industrial Chemicals like Alum (Ferrous Sulphate) & Dyes & Pigments
It is also used in neutralizing Alkaline effluent in the E.T.P. Plants of Textile Processing Industries for re-cycling of water
It is also used in extraction of Lignin precipitate from the Black Liquor generated in processing of pulp of paper
