ANDRITZ Dedert crystallizers: Waste reduction

We provide evaporative crystallizers which produce solids from a wide range of process and waste solutions. Applications include precipitation and/or purification of crystalline solids, cost-effective volume reduction of waste streams, and Zero Liquid Discharge (ZLD) systems in chemical, pharmaceutical, food, utility, and pollution control operations.

ANDRITZ Dedert forced circulation crystallizer

We provide evaporative crystallizers, which produce solids from a wide range of process and waste solutions. Applications include precipitation and/or purification of crystalline solids and cost-effective volume reduction of waste streams in chemical, pharmaceutical, food, utility and pollution control operations. In the ANDRITZ Dedert forced circulation crystallizer, feed continuously mixes with a circulation slurry of precipitated solids suspended in liquid. This slurry flows through the heat-exchange tubes of a chest while condensation occurs on the outside the tubes, providing the heat required for evaporation. The same energy sources utilized for evaporators are also relevant for crystallizers.
