Mechanical vapor recompression vacuum evaporators are designed to effectively treat industrial waste effluents from production processes and discharge from water treatment plants (brines), all with low energy costs. The high-efficiency is due to the use of a centrifugal fan or volumetric pump that increases the latent heat by the mechanical action of volumetric compression, with small electric consumption of the motor that activates the compressor. The compressed vapor heat transfers through a heat exchanger to heat the effluent to be evaporated and thus enables vapor condensation to produce distilled water. Under vacuum conditions, resulting from a centrifugal fan or volumetric pump, boiling and vapor temperatures go from 60ºC to 90ºC.
At Condorchem Envitech we offer three types of vacuum evaporators with mechanical vapor compression:
Modular configurations with several equipments working in parallel to treat larger volumes can be used.
Some of the main sectors and applications for these types of equipment are: Metal-mechanic and automotive supplies industry (superficial treatment baths, washers, finished glass washing baths, compressor blow downs, floor washing water, oil emulsions) and metals and light alloys injection casting (mould-releases, glycols, etc.). Chemical industry (production reactors washing). Leachates from MSW. Power generation plants (rejects from WTP, chemical room discharge, etc).
