In the process of sewage treatment,
polyacrylamide and
polyaluminum chloride are called golden partners, which occupy a very important position in the sewage treatment process. Polyacrylamide and polyaluminium chloride can be used separately or in combination. Henan Xinhuan Water Treatment Materials Co., Ltd. is a powerful polyacrylamide manufacturer in China. Next, we will introduce the difference between polyacrylamide and polyaluminum chloride and the matters needing attention when using them together. Polyacrylamide is a kind of polymer linear polymer, which can flocculate the fine particles with charge in water into larger flocs, and precipitate at the bottom of the sewage to clarify the wastewater. It can be used as coagulant aid in water treatment to improve the coagulation effect. Polyaluminum chloride can be distinguished from colors, including brown, yellow and white. To some extent, the product with yellow color has superior performance, while the white polyaluminum chloride is food grade, which is often used for the treatment of drinking water. In general, flocculant can be used. The combined use of polyacrylamide and polyaluminum chloride not only has better sewage treatment effect, but also can save the cost of pharmaceutical use, because the addition of polyaluminum chloride can save the amount of polyacrylamide, and the comprehensive cost and effect are better than the use of single product. Additive sequence : In the process of industrial wastewater treatment, if a variety of reagents are needed, we need to add them in batches. In general, inorganic flocculants, such as polyaluminum chloride, are first added, and then polyacrylamide is added. Can it be mixed : according to the experience of xinhuan technology, the two reagents cannot be mixed. In the process of use, polyacrylamide is used as a coagulant, and polyaluminum chloride is used as a coagulant aid. When the two reagents are directly mixed, flocculation reaction will occur. Dosing distance : In addition to the dosing distance of polyacrylamide and polyaluminum chloride, it is also necessary to pay attention to the dosing time of the two. Generally speaking, the interval of 20 seconds is better to add.
Dosage : In the process of sewage treatment, it is necessary to add a small amount of polyacrylamide and polyaluminum chloride. On the one hand, it is determined according to the amount of water treated, and on the other hand, it is also determined according to the two properties. Generally speaking, the dosage of polyaluminum chloride is more than 20 times that of polyacrylamide, and the dosing ratio needs to be determined by a small test of products.
