Applications:

  • recovery of substances contained in circulating waste streams (profitability improvement, limiting negative influence on environment),
  • recovery of salt contained in chemical wastes (also organic),
  • systems for volume reduction of poisonous and radioactive liquid wastes,
  • neutralization of saline liquid wastes for salt recovery,
  • concentration systems for spent beer, whey (in ethanol, biofuel production),
  • crystallization of ammonium sulfate, potassium and sodium nitrate, phosphoric acid (fertilizers),
  • crystallization of lithium salt, titanium, magnesium and zinc; vanadium, molybdenum, tungsten  crystallization products, concentration of cleared aluminum oxide liquid, recovery of oxalates,
  • preliminary processing of solutions from extracted natural ores,
  • crystallization of sodium carbonate and bicarbonate, minimizing wastes and lye recovery,
