Laundry detergent production machine ( 2) REDOX process, divided into chemical reduction method, the ferrite method and electrolysis method. ( 3) Solvent extraction separation process. Reverse osmosis water treatment making machine ( 4) Adsorption method. Laundry detergent packing machine ( 5) Membrane separation technology. Liquid detergent production machine ( 6) The ion exchange method. Washing powder production machine ( 7) Biological treatment techniques, including biological flocculation method, biological adsorption method, chemical method, and the method of phytoremediation. But there are certain defects or serious irrationality. Detergent production factory house, the previous: the source and harm of electroplating wastewater
