About Crystallizers
Crystallizers are machines used to convert wastewater into solid crystals and clean water. Crystallization is a solid-liquid separation technique in which solid crystals are formed from a liquid solution. Crystallizers can eliminate liquid wastes to create zero liquid discharge (ZLD). Crystallization is divided into two stages: primary nucleation and secondary nucleation. Primary nucleation involves the growth of new crystals. Secondary nucleation perpetuates growth and is the main stage that causes the mass production of crystals. There are three types of crystallization processes: concentration, cooling (under vacuum or with a heat exchanger), or by reaction or equilibrium displacement.
Selecting crystallizers requires an analysis of application requirements. For example, a salt crystallizer processes wastewater and produces both solid salt crystals and clean water. A resin crystallizer allows for the crystallization of flake or amorphous resin pellets. A vertical continuous cooling crystallizer (VCCC) is used to crystallize highly viscous and extremely slowly crystallizing fill masses. Other application-specific crystallizers are also available.
