Contribution to wastewater treatment using a numerical study of a secondary clarifier under Comsol Multiphysics
Journal Title: PhytoChem & BioSub Journal - Year 2018, Vol 12, Issue 1
Abstract
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.
