Evaporator with ascending film : simple effect

DESCRIPTION   This unit is designed to separate a solid (solute) from a solvent or to raise the concentration of solute in the solution. This separation occurs through the complete or partial evaporation of the solvent. The unit can be set up to operate automatically. Practical examples that can utilize this unit include increasing the concentration of fruit juices, milk or for the desalination of sea water or brackish water. In order to operate semi-automatically, data collected by the unit is sent to a command box, which in turn transmits it to a PC containing the required software. (This software is an optional extra)
