MKC Group of companies uses the technology of double-block vacuum distillation with mechanical steam compression, without external heat supply. Today, it is an innovative, unique development that has significant advantages in terms of energy efficiency and productivity in comparison with analogues. The key advantages of the technology are as follows: low specific energy consumption; low cost of the distillate produced; no external steam supply; the possibility of obtaining environmentally friendly fresh water; the possibility of regulating the processes depending on operation conditions.

Brief description of the UVV-2 block of the desalination UnitPre-filtered seawater heated in heat exchangers is supplied to the evaporator input. The vacuuming block creates a discharge in the stages, the water evaporates. In each subsequent stage, the steam condenses, giving off its heat to form the secondary steam, which goes to the next stage, producing distilled water. The non–evaporated seawater (the concentrated brine) is sent to the second block of the desalination plant – to the DCS.
Brief description of the DCS 2000 desalination unit
At the first stage, water evaporation to 70% wet concentrate takes place. At the second stage, the salt solution can be concentrated to a humidity of 30-40%. The vacuum use in the unit makes it possible to achieve a liquid boiling process at a temperature significantly lower than under the normal atmospheric pressure.
