Method and apparatus to avoid Aeration when downloading two mutually separable Solutions of the Liquid / liquid extraction from a separator comprising a Box type Landfill Pit (DivisionAl sol. 708 - 97).

摘要

The Invention relates to a method for adjusting the boundary Surface between two mutually separable Solutions in a liquid-liquid extraction.At the discharge end of the separation part, i.e. the Decanter, and to avoid the Aeration of the solutions when they are discharged from the Separation,So that the height of the Overflow of the lighter Sedimented Organic Solution, is kept Constant.To adjust the boundary Surface between the mutually separable Solutions.The height of the Overflow of the aqueous solution is adjusted by driving the heavier aqueous solution decanted from the bottom up through tubular Elements.The effect of height of the Overflow Pipe can be adjusted.The Aeration of the Solutions, when downloading the sedimentationThe Solutions are Avitan Driving Pipe transfer through boxes of landfill Wells covers, which are Deeper than the discharge End.The Invention also relates to a device with which the surface boundary between solutions can be adjusted and the Aeration can be avoided.
