Our state of the art technology is based on the simple principle of separation of materials due to boiling point deviations. The industrial wastewater is evaporated. All substances having higher boiling points than water stay in the evaporation residue. This includes heavy metals, salts as well as oils, fats and tensides. Because the clean water evaporates, the evaporation residue volume is reduced to anywhere between 0.5 and 5 percent of the original wastewater volume. The emerging vapor is practically free of impurities. After condensation it can be used as process water in the production process.
Some substances cannot be completely separated by this principle. Thus the distillate of conventional evaporators is often turbid and of poor quality, requiring post treatment. In recent years we could introduce many innovations setting benchmarks on the market regarding optimization of the separation process. Thus the VACUDEST process, compared to other conventional evaporators, guarantees crystal clear distillate with outstanding quality. Our Clearcat condensation system for instance allows COD reduction (COD: Chemical oxygen demand, a measurement for the degree of pollution with organic substances) of up to 99 percent.
There is not any heating element used in the device. On the contrary, there is a multistage recovery of thermal energy used. An extremely economical operation is a consequence.
