EVAPORATORS

EVAPORATORS





Traditional efficientprocessing systems for the treatment and disposal of waste water arecost-intensive and not sufficiently effective.

Vacuum evaporator to wastewater processing shows that it is possible to produce goods (e.g. in the galvanizationprocess) and to reduce the volume of waste water while at the same time cuttingthe burden on the environment.

The use of a vacuumevaporator is an advantage for the environment, and in practice results in areduction of current or expected residue disposal costs.

Vacuum evaporationtechnology is a process that has been used for decades by the chemicalindustry.

However, traditional distillationsystems require extremely complex installations and very high energy costs,which is why the evaporation process is uneconomical in most cases. On theother hand, vapour compressors are obliged to operate at high temperatures,leading automatically to corrosion and encrustations on the heat exchangers inthe absence of pretreatment, which again involves costs.

The structure of vacuumevaporators is based on the tried and tested technology of the heat pumpcombined with a vacuum, using an innovatory arrangement on the boiling andcondensation side to ensure an even more gentle distillation process, a higher yieldfrom the water, a higher degree of concentration and a significantly lowerconsumption of energy as compared with other products.

As is well known, waterboils at approx. 100u00b0C;the lower the ambient pressure, the earlier water will boil and evaporate,since the air resistance is lower. Under a vacuum (residual pressure) ofapprox. 40 mbar, the boiling point of water is only approx. 30u00b0C.

Boiling temperature plays amajor role in chemistry, the lower it is, the lower is the risk ofdecomposition in the case of many products. At the same time, encrustation isconsiderably cut back
