Correct Dosage of Drinking Water Grade Polyaluminium Chloride in Various Types of Sewage Treatment
drinking water grade polyaluminium chlorideIt has been widely used to treat various types of sewage, such as: treatment of printing and dyeing factory sewage, treatment of coal mine sewage, treatment of mineral processing sewage, treatment of papermaking sewage, treatment of aquaculture sewage, treatment of chemical industry sewage, etc., has become a common water treatment agent. However, at present, some users are still mistakenly using drinking water grade polyaluminum chloride, which hinders the full play of its efficacy, and also causes the waste and excessive consumption of drinking water grade polyaluminum chloride.
In different sewage treatment,drinking water grade polyaluminium chlorideThe dosage is also different, and the exact dosage can be obtained according to the experimental results. Precautions during the experiment: Willdrinking water grade polyaluminium chlorideThe solubility is controlled at 5%-10%, because the solubility of drinking water grade polyaluminum chloride is also different, the content is high and the solubility is low. When drinking water grade polyaluminum chloride is added to sewage, the dosage can be from less to more, from1‰ increased in turn until the treatment effect was achieved. Do not use too much, otherwise it is easy to increase the cost of sewage treatment.
in different water qualitydrinking water grade polyaluminium chlorideDosage usage:
1. In low turbidity water, the ratio of drinking water grade polyaluminum chloride to water can be1：4, and use tap water to dilute, stir until completely dissolved before adding.
2, in the domestic sewage, can be added first30KGAbout the product to each ton of water, in order to make the use of better, can be used in conjunction with polyacrylamide.
3. In industrial sewage treatment, it can be allocated according to the proportion of low turbidity sewage. If possible, high-content polyaluminum chloride products can be selected.
