| Summary: | The environmental assessment of the industrial effluents generated by the mineral fertilizer factory
complex, Fertial (ARZEW), which discharges into the seacoast its liquid effluents loaded with organic and
inorganic pollutants without adequate treatment [1] have revealed concentrations intense of suspended mater
(SM). Wastewater treatment is a multi-step process to remove contaminants. In the first place, large solid
particles are removed by sedimentation, flotation and filtration. In a second step, the biological treatment
aggregates the smaller particles, forming so-called flocs. These flocs can be easily removed by sedimentation. This
investigation investigates the separation of flocs from water in a circular secondary decanter. A mixing model is
used to model the multiphase turbulent flow in the reservoir.
