The results of studying the reuse of sedimented coagulant in the processes of chemical water dephosphotation

Summary

The results of a research study of possible reusing sedimented aluminium-based coagulant in the processes of chemical wastewater dephosphotation are presented. The experimental findings on determining the actual dosage of coagulant – polyoxychloride of aluminum – for chemical phosphorus removal. Empirical data are presented confirming the high repeated effect of dephosphotation while using previously sedimented coagulant. Possible reusing the coagulant in order to increase the efficiency and reduce the costs of wastewater treatment in general is experimentally confirmed.

Key words
