Mathematical Modeling of Motion of the Solid Particles in the Filter-Coalescer Wastewater Treatment

Abstract

The purpose of this article is to describe the method of calculation of the motion of particles in the filter-coalescer wastewater treatment based on the mathematical description of the motion of the cleaning fluid and the particles in the channel coagulator. It is found that fine particles in the coagulator move in a stream so that the process of consolidation and coalescence occurs at specific sites in the gap between the cones, with little flow velocity vector changes in direction and magnitude that the process provides an efficient aggregation of particles. The length of this section should be sufficient to ensure that the bulk of the particles reach a critical size. This allows the particles to migrate subsequent channel sections coagulator holding particles in the flow, and eliminating such deposition of particles on the internal surfaces of the device even when moving within the annular gap. The scheme of the electromagnetic filter of the coagulator, the two-dimensional scheme of the magnetic coagulator, the scheme of epure of speed vectors in the canal of the coagulator and the scheme of particle interaction in the canal of the coagulator are given too.
