Polyaluminum chloride (PAC) is a commonly used water treatment agent, commonly used for purifying and purifying water sources. It is mainly used to remove suspended solids, colors, flavors, and dissolved organic substances from water. The following are the basic usage methods of polyaluminum chloride:
Dilution: PAC is usually supplied in solid or liquid form. If you are using solid PAC, you need to dilute it into liquid form, usually within the concentration range of 10% -30%.
Mixing and stirring: Add diluted PAC liquid to water, usually in a water treatment equipment. Before adding PAC, ensure that there are no excessive impurities and precipitates in the water to ensure the effectiveness of PAC.
Adjusting pH value: The performance of PAC is usually better in acidic or neutral environments. Before using PAC, it may be necessary to adjust the pH value of the water to ensure the optimal effect of PAC. Under acidic conditions (pH below 7), it is usually more suitable for the use of PAC.
Dosing and stirring: Add the diluted PAC liquid evenly to the water and stir thoroughly to ensure that the PAC is fully mixed and reacts with pollutants in the water.
Precipitation and filtration: PAC reacts with pollutants in water to form sediment. Usually, the treated water undergoes a sedimentation and filtration process to remove sediment from the water and obtain a clear water source.
Monitoring and adjustment: After using PAC for water treatment, it is necessary to regularly monitor the water quality to ensure the effectiveness of PAC use. Based on the monitoring results, it may be necessary to adjust the dosage or frequency of PAC to meet water quality requirements.
The specific usage method and dosage should be adjusted based on the characteristics of the water source, water quality requirements, and the situation of the treatment equipment. It is recommended to consult a professional water treatment engineer or water treatment company before using PAC for water treatment to obtain the best usage advice.
