Application range of polyacrylamide

The problem of sewage has always received much attention. Different treatment agents will be selected for different sewage, and the chemical reaction between them will be used to produce the effect of treating sewage. It can be said that polyacrylamide (PAM) is a kind of more suitable for treating various sewage A medicament can not only effectively treat sewage but also have no secondary pollution. What are the scope of polyacrylamide?

1. The function of polyacrylamide

        (1). Used for sludge dewatering According to the nature of the sludge, the corresponding model of this product can be used, which can effectively carry out sludge dewatering before entering the filter press. During dewatering, the flocculation is large, and the filter cloth is not sticky. Scattered, thick mud cake, high dehydration efficiency.

   (2). For the treatment of domestic sewage and organic wastewater, polyacrylamide shows positive electricity in compatible or alkaline media, so as to flocculate the sewage with negatively charged suspended particles in the sewage.

  (3). Reinforcing agent for papermaking and other auxiliary agents. Improve the retention rate of fillers and pigments, and the strength of paper.

   (4). Used in oilfield economics auxiliaries, textile sizing agent, stable slurry performance, low fabric breakage rate, less sizing, and smooth cloth surface.

2. Scope of use of polyacrylamide

   (1). The pollutants of printing and dyeing wastewater are mainly the dirt on textile fibers such as cotton wool, salts, oils and lipids. Generally, polyacrylamide PAM and polyaluminum chloride PAC combined flocculant are used for advanced treatment of printing and dyeing wastewater.

   (2). The removal effect of organic coagulant is better than inorganic coagulant. After the addition of PAM, when the amount of polyaluminum chloride PAC is small, the color and organic matter can achieve a better removal effect, saving the amount of PAC. Because PAM is an organic polymer flocculant, it can enhance coagulation through the adsorption of its chain molecules and effectively increase the floc particle size. Through the function of bridging flocculation and network flocculation, the floc is closely combined, and the sedimentation speed of the particles is accelerated, so that the color and organic matter removal rate can be improved.


The main role of polyacrylamide is to treat various industrial wastewaters and restore the water to a clear state. Its role is no less than that of some water treatment equipment, so its use range is mainly in some industries that often produce wastewater because of water pollution. The problem has aroused the attention of many people, so it is time to choose the right water treatment agent for sewage treatment and protect the ecological environment.
