How to calculate the dosage of polyaluminium chloride water purification agent

Our common water purification agents are polyacrylamide, polyaluminium chloride and other products. In use, how do we calculate the dosage of polyaluminium chloride water purification agent? First, a small test to dissolve polyaluminium chloride We first need to take the raw water to do a small test according to the different conditions of the raw water, and then the amount of dosage to be obtained before the use of the machine. In the experiment, in order to facilitate the calculation, the configuration of the small test solution according to the weight ratio (W/W), generally 2-5% configuration is good. For example, to configure 3% of the solution, weighing polyaluminium chloride solid 3g, put into a washed 200ml container, add about 50ml of water, wait for it to dissolve and then add water to dilute to 100ml, shake well. Second, on the machine to run the ratio of polyaluminium chloride According to the polyaluminium chloride solid, water = 1:9 to 1:15 weight ratio, the liquid polyaluminium chloride using 1:2 to 1:5 weight ratio, mixing and dissolving can be. Here we should note that when the content of alumina is less than 1%, the solution is easy to hydrolysis, which will reduce the effect of use; on the contrary, when the concentration is too high, it is not easy to add the average. Third, calculate the dosage in the machine dosing, according to us in the small test when the amount of dosage, and in the operation of the attention to check the adjustment. If there are few precipitation alum flowers, turbidity is big, then it means that the dosage is too small; if there are big alum flowers in the precipitation pool and upturned, the turbidity is high, it means that the dosage is too big, and it should be reduced immediately and appropriately. In fact, how to correctly add the dosage of polyaluminium chloride, the above calculation is just a preliminary measurement, in the actual use, but also according to the actual situation of the site to add.
