A crystallizer is processing equipment used to transform wastewater into solid crystals and pure water. Solid crystals are created from a liquid solution through crystallization, also known as a solid-liquid separation process. Liquid waste may be eliminated by crystallizers, resulting in Zero Liquid Discharge (ZLD). Primary nucleation and secondary nucleation are the two steps in the crystallization process. New crystals development is called primary nucleation. Secondary nucleation is the major stage that leads to the bulk formation of crystals and is what keeps growth going.
