Polyaluminum Chloride: A Review of Its Water Treatment Capabilities
1.Polyaluminum sulfate is generally an orange-yellow or light yellow powder, and its main application is in water treatment.
2.When conducting water treatment, it is necessary to first dissolve and dilute the powdered PAC.It is recommended to conduct beaker tests before actual application to determine the optimal dosing concentration and dosage.
3.After pouring into the wastewater to be treated, continuous stirring is required to ensure that the PAC solution is thoroughly mixed with the wastewater.
4.The hydrolysis of PAC in water forms aluminum hydroxide colloids, which are the key substances for adsorbing tiny impurities in water.
5.After allowing the mixture to settle for a period of time, the water is then filtered to obtain the treated water. In most cases, the water treatment process is not complete until the pH of the water is adjusted.
6.Precautions:Daily Use of Prepared Solution: It is best to use the prepared solution on the same day to avoid precipitation of the active components.
Corrosion Prevention: Although the corrosion of equipment and pipelines by polyaluminum sulfate is relatively low, it is still necessary to pay attention to the anti-corrosion measures of the storage and dosing systems.
