An important note: all types of wastewater are unique in composition. We develop a unit for a specific type of wastewater. The technology combines well-known and tested wastewater treatment methods, such as:
Precipitation of hardness salts by liming/soda-liming in clarifier.
Concentration at a flash evaporator. Over 30 units based on this technology have been developed for various purposes.
Evaporation and crystallization of highly-concentrated wastewater in a conventional vertical evaporator with forced circulation. This technology is commonly used as a typical solution for salt solutions.
