Five unit groups configured to the process stage #
Industrial process liquids, raw materials, and intermediates often contain large amounts of water and impurities or require concentration. Yuan Chang organizes filtration, thickening, dosing, dehydration, and drying equipment into five groups that can be used individually or integrated into a treatment system.
