Abstract:
In the paper were established the optimum conditions of aluminium removal from residual industrial waters. In the frame of
the experimental study the parameters of the initial water have been determinate. In the situations in which the residual effluents
volume is small, the proceeding being discontinuous it’s applied the physical – chemical independent treatment of this. The
precipitation agents used in classic mod are lime milk, sodium hydroxide or sodium carbonate. The neutralisation process of the
effluent must be lead in the pH limits = 6.5 – 8.5 in accordance with the indicators of the waste waters quality evacuated in sewerage
system.
