How to use polyaluminum chloride

1.Before use, take water samples and chemicals for a small test based on the actual water quality to determine the optimal amount of water to be treated. Pay attention to observation and adjustment during operation. If there are few alum flowers and high turbidity in the sedimentation tank, add The dosage is too small; if the alum flowers in the sedimentation tank are large and turned up, and the turbidity is high, the dosage is too large and should be adjusted appropriately.

2.It is best to prepare the polyaluminum chloride solution as it is used. How much is used and how much is prepared. Before use, the polyaluminum chloride dissolving device and chemical output control device (made of corrosion-resistant materials) must be installed. Polyaluminum chloride must be dissolved with clean water and cannot be dissolved with sewage or oily wastewater.

3.Mix the solid product and water at a ratio of 5% and stir for about 10 to 30 minutes.Use the medicine after it is completely dissolved into liquid.

4.When the source water turbidity is 100-500mg/L, the dosage is 5-10mg, that is, the dosage per thousand tons of water is 5-10kg. It is best to conduct a small test based on the water quality characteristics before use. Pick the best value and put it to use.

5.The amount of chemicals added should be well controlled and change based on the results of preliminary small tests and actual changes in water volume and quality on site.
