Experiments performed with two different configurations: feed solution is circulated at constant temperature of 49 °C (A); the feed solution line is broken down in two crystallization stages working at the same concentration factor but different temperature: 31 °C and 44 °C (Tx: temperature probes; Kx: conductivity probes; Px: pressure sensors; PPx: peristaltic pumps; HEx: heat exchangers; CnTR/PC: programmable logic controller connected to a PC) (B).
