That is added in a concentration of mercury in waste water containing 12% of non-metallic reducing agent is sodium perborate, and then put into the base (water pH = 9 ~ 11) mixture to produce mercury particles (diameter about 10 microns), Hydrocyclone Separation Recycling. The mercury remaining in the overflow is separated by water and gas and trapped by a filter having a pore size of 5 μm. The mercury vapor in the exhaust gas is washed with dilute nitric acid and returned to the original wastewater tank for recycling. The method has been used in industrial production in the United States, and the amount of residual mercury in the discharged wastewater is less than 0.01 mg/L. The process flow is shown in the figure below. Latex Balloon ,Emerald Green Balloons,Metallic Gold Balloons,Rubber Balloon NINGBO YAOTU TRADING COMPANY , https://www.zjnbyaotu.com
