Application of Activated Carbon Tn The Treatment of Groundwater
When groundwater is used as water source, the content of suspended solids in the water is very small, so the establishment of pretreatment is generally not considered. If sand is contained, sand removal equipment should be considered. When the water contains inactive silicon, and the boiler steam quality cannot meet the requirements after accounting, it should be removed by touch coagulation, coal-based activated carbon filtration or coagulation, clarification, and filtration. When the content of iron and manganese in groundwater is high, the method of removing iron and manganese should be adopted. When the bicarbonate iron is less than 20mg/L and the pH is greater than or equal to 5.5, the aeration-natural manganese sand filtration method can be used to remove iron. If the salt type iron is less than 4mg/L, the iron can be removed by aeration-quartz sand filtration, and the pH after aeration can be made >7 (if necessary, the water can be alkalized to pH>7). Application of activated carbon in surface water treatment: Coagulation, clarification and activated carbon filtration should be used for surface water pretreatment.When the content of suspended solids in the water is small, touch coagulation and filtration can be used. If there is a seasonal...
