The survey revealed the fact that in India, alum is used for the improvement of effluent quality but the work on alum recovery and reuse is fragmentary. Therefore this work emphasized on recovery of alum from sludge and its reuse for waste water treatment. Various methods have been reported for treatment and disposal of alum sludge. Use of alum sludge or recovered alum as tried in Sanchi dairy waste water treatment has gained significant acceptance.
