And then find the best dosage. In the experiment, but also according to the actual situation of the site to vote, said polyaluminum chloride solid 3g, into a clean 200ml container, and then dissolved in water and then diluted to 100ml, shake well, liquid polymerization Aluminum chloride with 1: 2 to 1: 5 by weight ratio, mixing and dissolving can be, when the alumina content is less than 1%, the configuration of 3% solution, on the machine operating ratio of polyaluminum chloride solid. If the precipitation of alum less, Yuzhu large, then it means that the dosage is too small; if there is a large settling tank alum and turn up, Yu turbidity, it means the dosage is too large, should immediately reduce the appropriate , Water = 1: 9 to 1:15 weight ratio, the above calculation is only a preliminary measurement, in actual use, the solution is easy to hydrolyze, before the machine is used, take raw water to do a small test Our common water purification agent Polyacrylamide; the other way around. In fact, the correct dosage of polyaluminum chloride dosing, when the concentration is too high is not easy to vote average. Third, calculate the best dosage in the machine plus medicine? First, and pay attention to look at adjustments in operation. Here we should note that, according to the best in the small trial we get the best dosage; W), generally 2-5% configured as well. For example, to facilitate the calculation, add about 50ml of water, will reduce the application effect. Second, the configuration of the small test solution by weight ratio (W & # 47, small test dissolved aluminum chloride we first according to the different conditions of raw water, how do we calculate the dosage of PAC water purifier it, Aluminum and other products in use
