Rectification measures. If there is a significant change in the seepage water body of the reverse osmosis equipment, a comprehensive analysis of the water body related to the source water should be carried out. If there is no standard chemical laboratory, it is also advisable to seek relevant departments or brother companies with standards as much as possible to send water quality samples and help with comprehensive analysis and testing of water bodies. Based on the test results, identify the relevant chemical substances that cause an increase in conductivity, and take effective technical measures in the preparatory treatment.

If the total silicon content increases, a silicon removal strategy can be adopted. Before coagulation, appropriate Lingkutu magnesium oxide or aluminum sulfate or coagulants can be added. Polyaluminum chloride can reasonably remove silicon and colloidal silicon from the raw water. If the total silicon content in the raw water is between 10-15mg/L and the dosage is controlled around 5-10mg/L, the silicon content in the raw water can be reduced to below 0.3Mg/L, which can reasonably reduce colloidal silicon environmental pollution and water conductivity. If the iron content in the raw water is high, the quartz sand cushion layer of the filtration device or activated carbon filter can be replaced with a part of the manganese sand filter material, which can reasonably remove the iron content in the water. Alternatively, a certain amount of potassium permanganate solution can be added to the raw water before coagulation to oxidize the divalent iron air in the water to trivalent iron, which can be removed by coagulation filtration, and can reasonably reduce the environmental pollution of colloidal iron Fe (OH) 2 in the water.
