Forced Circulation Crystallizer for ZLD

Forced Circulation Crystallizer for Water and Wastewater Zero Liquid Discharge (yasa.ltd)

A Zero Liquid Discharge system consists of three main stages:
 
(1) pre-concentration;
 
(2) evaporation;
 
(3) crystallization stage.
 

 
Different membrane-based and thermal-based technologies, including reverse osmosis, brine concentrator, forward osmosis, electrodialysis, and humidification-dehumidification, are utilized in various stages of the ZLD approach.
 

 
One of the common components used in the third stage of ZLD wastewater treatment is the crystallizer, where the crystallization process occurs. The crystal production process or crystallization is a liquid-solid separation method in which the solute is separated from the liquid solution and forms a pure crystalline solid phase.
