Emulsion Flow Through an Electric Filter

The obtained dependences can be used to determine the duration of emulsion treatment in the electric field necessary to achieve a required volume concentration of the disperse phase at the settler exit. 

The process can be described in terms of filtering of the disperse phase by a system of mesh electrodes. The primary goal is to determine the amount of residual water in the oil product at the filter exit. The volume concentration of water Woui at the exit depends on the volume concentration at the entrance Wi , disperse structure of the emulsion, electric field strength, construction parameters of the device, and physico-chemical properties of the emulsion. 

Define the ablation factor of one filter section volume concentration of water in the emulsion at the exit divided by the concentration at the entrance  

to determine the volume concentration of water at the exit from the filter, Wout = KWi , we must know the ablation factor of each filter section. Take all sections of the filter to be identical and consider the process occurring in one section. 

Suppose the emulsion consists of a non onducting continuous phase and a conducting disperse phases in the form of identical small spherical drops of radius R carrying a constant charge q. The drops move between two parallel flat mesh electrodes. On a large distance from the electrodes, drops move perpendicularly to the mesh plane. Assume that drops acquire the charge as a result of collisions with electrodes. Then, according to [98],
