Principle of operation

The process features an ingenious heat exchanger system and is based on the principle of low-pressure, low-temperature evaporation.

The salt water/dirty water contained in the tank on the evaporator side is warmed up using a heating medium and kept under low pressure until the liquid evaporates. Under the pressure conditions prevailing in the evaporator, the water already boils off at approx. 30°C.

The water vapour is fed via piping to the condenser side and by a sophisticated spray-system condensed into a salt-free distillate.

Through the use of low-temperature heat (e.g. waste heat), the plant is also cheaper to operate than traditional systems. Moreover, the energy can be employed repeatedly in thermal cascades. The condensate is circulated, cooled down externally and is used once more as a cooling medium. Large internal heat exchangers are not necessary.

Compared with other processes, the plant is insensitive to soiling (scaling) and highly efficient as far as its performance is concerned. It is self-regulating as far as pressure and temperature are concerned. The plant can be manufactured and operated in a modular manner.

The plant is simple in construction, has no metallic heat exchangers inside the tanks and can be manufactured to a large extent using cheap materials (plastic).
