The Advantage of Mixed Salt Crystallizers in Zero Liquid Discharge Wastewater Treatment Systems

摘要

The crystallization process has long been used in the manufacture of commodity chemicals . However, unlike commodity production where only one salt precipitates, reducing industrial waste to dryness involves crystallizing multiple salts. A mixed salt crystallizer requires significantly different design parameters to avoid foaming and scaling. This paper will examine four types of mixed salt crystallizers used to reduce industrial wastewater to dry solids.
