How to Maximize The Use Effect of Polyaluminum Chloride

Polyaluminum chloride is divided into plate frame, spray, roller three types. The market application is more plate frame and roller, spray, less.So How Do You Use Polyaluminum Chloride?

⒈ According to the different conditions of raw water, you can do a small test before use to obtain the best dosage. In order to facilitate the calculation, the configuration of the small solution is based on the weight ratio (W/W), generally 2-5 is better. For example, with 3 solutions: called polyaluminum chloride solid 3g, put into the washed 200ml cylinder, add water about 50ml, to be dissolved and then dilute to 100ml scale, shake well.

⒉ The supplier can mix and dissolve according to the weight ratio of polyaluminum chloride solid: water = 1:9 to 1:15 (1:2 to 1:5 for liquid products). The solution with alumina content lower than 1 is easy to hydrolyze, which will reduce the use effect, and the concentration is too high to add evenly.

⒊ add medicine according to the best dosage obtained from the trial, and pay attention to the adjustment in the operation. If the sedimentation tank alum flower is less, the turbidity is large, the dosage is too small; If the sedimentation tank alum is large and upturned, the turbidity is high, the dosage is too large, should be adjusted appropriately.
