VACUDEST - Wastewater Evaporator with Energy Recycling
Energy is an expensive production resource. To save energy we've relied since 1986 on the energy efficient process of direct vapor recompression. The industrial wastewater is evaporated under a slight vacuum. This reduces the boiling temperature of the water. The emerging steam is compressed to ambient, normal pressure and heated up by means of a vapor compressor. The energy of the hot steam is recycled to evaporate the wastewater. Due to the energy recycling in the waste water evaporator no additional evaporation energy is required. The electrical motor of the vapor compressor is the sole energy consumer in the wastewater evaporator system. Thus the VACUDEST wastewater evaporator has an energy efficiency of 95 percent.
One of our goals, as we continue to further develop our VACUDEST wastewater evaporator systems, is to improve energy efficiency. We provide for optimal heat transfer from the steam to the wastewater. Also the residual heat in the distillate is used efficiently to pre-heat the wastewater entering the system. In the last 10 years we could reduce the average energy consumption in our VACUDEST wastewater evaporator systems by 28 percent. Our modern VACUDEST wastewater evaporator systems stand for highest energy efficiency and lowest operating cost.
