Optimization of the flocculation process of industrial waste water treatment
Keywords:flocculation, aggregation, strength of aggregates, deposition rate, optimization, hydromechanical destruction of floccules
The influence of the concentration of the solid phase and the flow rate of the flocculant on the change in the sedimentation rate of the solid phase and the strength of the floccules is studied. A technique is proposed for optimizing the parameters of aggregation and increasing the strength of floccules after hydromechanical influences, taking into account the concentration of the solid phase and the flocculant flow. It is found that the optimal conditions for aggregation can be achieved by minimizing the hydromechanical effects on floccules, as well as creating the best conditions for flocculation. Among the ways to optimize the process, the ways of influencing these factors due to the technological features of the introduction of the process are analyzed, such as concentration adjustment, transport rate of flocculed sludge, mixing time
