The viscosity of polyacrylamide solution mainly reflects the internal friction resistance generated by the flow or relative movement between liquid molecules. The internal friction resistance is related to the structure of the polymer, the properties of the solvent, the concentration of the solution, and the temperature and pressure. The larger its value, the greater the …
(PAM) polyacrylamide is a general term for acrylamide homopolymer or polymers copolymerized with other monomers. (PAM) polyacrylamide is one of the most widely used varieties of water-soluble polymers. (PAM) polyacrylamide is widely used in oil extraction, papermaking, water treatment, textiles, medicine, agriculture and other industries. According to statistics, 37% of the total global (PAM) polyacrylamide …
Reason 1: The influent volume suddenly increases, the retention time of the secondary sedimentation tank is shortened, and the activated sludge flows out of the secondary sedimentation tank before it can settle, resulting in sludge running. At the same time, the increase in influent concentration will lead to the enhanced activity of activated sludge, which …
1. The impact of pH value on sewage treatment PH value is an important indicator to measure the acidity and alkalinity of sewage, and has an important impact on the sewage treatment process. Overly acidic or overly alkaline sewage will have adverse effects on treatment facilities and the environment. Overly acidic sewage will cause corrosion …

Polyacrylamide (PAM) is a linear polymer with the chemical formula (C3H5NO)n. Physical properties: At room temperature, polyacrylamide is a hard glassy solid that can be dissolved in water in any proportion to form a uniform transparent liquid. Its products are in various forms, including glue, latex, white powder, translucent beads and flakes. Polyacrylamide has …
Polyacrylamide treatment of sand washing wastewater Sand washing wastewater refers to wastewater containing suspended matter, heavy metals and other pollutants generated by the washing of sand and gravel in construction sites, quarries, mines and other places. This kind of wastewater will have a great impact on the environment and human health. In order to solve …

Classification of polyacrylamide Polyacrylamide can be divided into nonionic, anionic and cationic polyacrylamide. Non-ionic: (NPAM), neutral, uncharged. ① Neutral or acidic sewage is more commonly used, such as mineral processing wastewater, stone factories, engineering mud, and printing and dyeing factories. ② The flocculation effect mainly relies on a large number of molecular groups on the …
Micro-electrolysis technology is currently an ideal process for treating high-concentration organic wastewater, also known as internal electrolysis. In a nutshell, it uses the 1.2V potential difference generated by the micro-electrolysis material filled in the wastewater to electrolyze the wastewater without electricity, so as to achieve the purpose of degrading organic pollutants. When the system is …
Coagulants and flocculants for algae removal Adding aluminum sulfate as a coagulant can remove turbidity and algae at the same time. When the number of algae in the effluent is less than 1000/mL, the amount of coagulant required is much greater than the amount required when the turbidity is less than 3 NTU. The reason …
