PROCESS FOR THE REDUCTION OF THE CONCENTRATION OF SALTS IN AN AQUEOUS STREAM CONTAINING THEM
摘要
Process for the reduction of the concentration of salts in an aqueous stream containing them comprising the following steps : production of ice by continuous crystallization in suspension obtained by the partial freezing of said aqueous stream, effected by means of indirect heat exchange with a cold fluid having a temperature lower than or equal to -2°C; separation between the ice produced and the concentrated brine obtained by partial freezing and subsequent washing of the ice in one or more steps; melting of the separated and washed ice to obtain an aqueous stream with a reduced concentration of salts.
