Hard Skills
IntermediateClarifier Process MonitoringThe systematic observation and adjustment of sedimentation tanks to separate alumina liquor from red mud residue using physical and chemical parameters.
IntermediateFlocculant Dosing OptimizationThe precise application of chemical polymers to enhance the settling rate of suspended solids within the clarifier.
IntermediateDistributed Control System (DCS) OperationThe use of computerized interfaces to monitor flow rates, temperatures, and rake torque across the clarification circuit remotely.
AdvancedUnderflow Density ManagementRegulating the discharge rate of concentrated mud from the bottom of the clarifier to maintain optimal solids-to-liquid ratios.
IntermediateHazardous Material Handling (Caustic Safety)Strict adherence to safety protocols when working with hot, corrosive caustic soda solutions used in alumina refining.
IntermediateEquipment TroubleshootingIdentifying and diagnosing mechanical or process failures, such as pump cavitation or rake torque spikes, before they cause system failure.
