Tratamiento de aguas residuales industriales mediante evaporación al vacío


Oferta Tecnológica
Una empresa austríaca ha desarrollado un proceso de purificación de aguas residuales industriales y reutilización de la materia prima. La instalación del sistema de evaporación en naves industriales permite reducir considerablemente el volumen de aguas residuales. El sistema consiste en una cámara de ebullición hermética. La evaporación y condensación de aguas residuales mediante una bomba de calor o mediante la recuperación de calor residual se realizan al vacío, lo que permite separar las partículas residuales del agua. El uso de un circuito de refrigeración mantiene el equilibrio correcto de las temperaturas de forma eficiente. Una vez que se ha completado el proceso de filtración, el 97% del agua puede ser reutilizada. La empresa busca socios industriales con el fin de establecer acuerdos de licencia o comercialización con asistencia técnica.


Industrial wastewater treatment through vacuum evaporation
An Austrian company has developed a process for the purification of industrial wastewater and the reuse of the raw material. The installation of the evaporator system into industrial facilities allows a considerable reduction of volumes of sewage to dispose. The company is looking for industrial partners through license agreement or commercial agreement with technical assistance.
An Austrian company with more than 30 years of experience in engineering of wastewater systems for industrial applications has developed a concentration system through vacuum evaporation.

The invented system for purification of industrial wastewater consists of a hermetic boiling chamber, maintained constantly under vacuum, in which the boiling of the water occurs and the condensation of water vapors. Evaporation and condensation of the wastewater through an integrated heat pump or through recovery of waste heat takes place in a vacuum, allowing for fresh water and waste particles to be separated. A refrigeration circuit allows to keep the correct equilibrium of the temperatures in an efficient way. Once the filtering process is complete, 97 percent of the water can be reused. The system does not require any chemical material.

- Completely automatic, continuos operation
- Evaporation and condensation through an integrated heat pump
- Parts in contact with the product (waste) are made of stainlesss steel
- Vertical or horizontal boiling chamber
- Piping made of PVC or PP (polypropylen) or stainless steel
- Inspection glass with LED light and washing device with internal sight-glass wiper
- Level adjustment through reed-contact switches or vibration forks
- Switch cabinet with integrated Siemens PLC built in accordance with the CEI/VDE norms
- Siemens Operator Panel or on request synoptic panel
- Possible use of other materials or special components
- Standard systems cover a production from 50 up to 50.000 litres of distillate per day

The Austrian company is looking for industrial partners from various sectors who are interested in implementing the vacuum evaporation system for the treatment of their wastewater under commercial agreement with technical assistance. And they are also seeking industrial partners as licensees who want to add the technology to their product portfolio and sell the product under license agreement.
Advantages and Innovations:
The innovative vacuum evaporator structure, unlike traditional systems, uses a novel placement of the boiling and condensation elements allowing even more delicate distillation, a greater separation of water, with a higher degree of concentration and a lower energy consumption. The system is versatile and can be customized according to the effective needs of each customer.

Further advantages:
reduce the volume of sewage and therefore costs
autonomous and controlled running of the system
no chemicals needed
control of working parameters with PLC (Programmable Logic Controller)
24/7 operation
low maintenance costs
