Abstract
One of the methods to treat open-pit wastewater is coagulation, which is carried out by continuous introduction of coagulants to form a suspended mixture that contains aggregates of polluting particles. Suspension separation and removal of the dispersed phase can be effectively performed using a hydrocyclone. Stability of the hydrocyclone operation and the high efficiency of the separation process are ensured by calculation and selection of the hydrocyclone design parameters, as well as by automatic regulation of technological variables of the separation process. An automation scheme of the coagulation process is proposed. An automatic control system (ACS) of the main technological parameter, i.e. pressure in the hydrocyclone – is studied. A structural automatic pressure control system is designed, and the transfer functions of ACS elements are obtained. Parameters for the automatic pressure controller are calculated. Analysis of the ACS modelling results using the Simulink Matlab application tools has shown the efficiency of applying the PID-law for pressure control in the hydrocyclone.
Keywords
