DISTILLATION TECHNOLOGY FOR INDUSTRIAL WASTEWATER TREATMENT AND PROCESS WATER RECOVERY
MVR Evaporators can be described as mechanical vapour compression technology. MVR is a qualified technology that provides significant energy savings with the re-use of the vapour again. In the early 1960s, Germany and France used MVR technology in the fields of chemicals, foodstuffs, paper industry, pharmaceuticals, seawater desalination and wastewater treatment. In the MVR evaporation system, water vapour with compressor compresses under pressure and temperature. By the way, enthalpy is increased and the efficiency of the system is achieved by increasing the thermal capacity required for the system. It is the best solution for areas where electrical energy is cheap. Because the amount of steam used is reduced. 90% of water saving in a cooling system. This is a much more cost-effective method than multi-effect steam energy.
Evaporation or distillation is a kind of separation process from other pollutants by taking advantage of its physical properties.
The wastewater containing the pollutants is brought to the boiling point at low temperature and under appropriate vacuum and the evaporation is initiated only for the water. Pollutants are not allowed to evaporate (boiling points are usually very high)
The steam compressor used as a vacuum source compresses the vapour absorbed from the system to approximately atmospheric pressure. This raises the temperature of the compressed steam (~ 120 ͦ C)
The energy (latent heat) required for continuous evaporation is transferred to the evaporator for recovery. The compressed steam, which loses its energy, becomes condensed into distilled water. While distilled water is drawn out (~ 85 ͦ C) from the system, it contributes to the performance by heating the wastewater entering the system by means of a heat exchanger.
The only energy consumption required to operate the system is the engine of the steam compressor. A very large percentage (95%) of the latent heat required for evaporation is uniquely reduced.
Such systems using mechanically compressed vapour are commonly referred to as MVR evaporators.
What is MVR (Mechanical Vapor Recompression)?
It is intended to recover the energy carried by the mechanical compression of the steam formed in the evaporator during water evaporation under vacuum and to use the recovered energy in the evaporation again.
Therefore, very low energy consumption is possible with a unique efficiency (30-50 Kw / ton distilled water)
MVR evaporators are suitable for low-temperature condensation for milk, glucose, organic acid, VC, xylopyranose, chemicals like copper sulphate, ferrous sulphate, zinc sulphate, chemical crystallization process, biologicals, environmental protection, wastewater treatment projects.
