Introduction In many industrial and daily – life processes, the formation of foam can be a troublesome issue. Foam is a dispersion of gas in a liquid, which is stabilized by surface – active substances. Excessive foam can lead to problems such as reduced production efficiency, inaccurate metering, and even equipment damage. Defoamers, also known …
Polyacrylamide (PAM) dosing conditions Dissolution conditions: ○ Water quality: The water used to dissolve PAM should be clean, neutral, and free of salt impurities. Avoid using water containing iron ions or other impurities that may react with PAM. ○ Temperature: It is usually recommended to dissolve PAM between 5℃ and 60℃. Too low a temperature …
Coagulation and 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 is …
Polyaluminum sulfate usage effects: 1. Significant water purification effect: As an inorganic polymer coagulant, the principle of water purification is mainly through agglomeration, adsorption and bridging, etc., so that small suspended particles and colloids in the water agglomerate to become larger and heavier, thus Settling down. This process can not only effectively remove suspended solids, …

Polyacrylamide (PAM) Polyacrylamide is a synthetic polymer with a wide range of applications in various industries. 1. Chemical Structure and Properties Chemical Formula: The general formula of polyacrylamide is . It is a linear polymer that is formed by the polymerization of acrylamide monomers (). Solubility: It is water – soluble, which is …
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 …
