When a sewage treatment plant is treating wastewater, the commonly used coagulants mainly fall into two categories: inorganic coagulants and organic coagulants. Inorganic coagulants include polyaluminium chloride (PAC), poly硫酸 ferric chloride, ferrous sulfate and basic aluminum chloride， etc. While organic coagulants include polyacrylamide (PAM)， chitosan coagulants and cationic polyamines， etc. The effectiveness of these coagulants …

Why do we need to select a type of polyacrylamide (PAM)? The types of sand are different, the types of mud are different, and the drugs are completely different. Gravel sand, machine-made sand, river sand, mountain sand, the amount of mud content, the fineness of the slurry, the flocculation effect varies greatly. Without selecting the …

I. Composition of Flocculant Raw Materials Flocculants are mainly composed of two types of raw materials: natural polymers and synthetic polymers. The natural category includes traditional materials such as alum and starch, while the synthetic category is represented by polyacrylamide. These raw materials work through charge neutralization and adsorption bridging to cause suspended particles in …

In the mining and beneficiation fields, polyacrylamide (PAM) is mainly used as an efficient flocculant. It helps achieve high solid-liquid separation, treat wastewater, recover resources, and protect the environment. Main functions Solid-liquid separation: During the beneficiation process, a large amount of wastewater containing slag will be produced. Polyacrylamide can cause the sludge and impurities in …

Polyacrylamide is a linear polymer. The following precautions should be taken when storing it. Storage Instructions 1. Dry Environment: Store in a dry, well-ventilated warehouse to prevent moisture. High humidity can cause polyacrylamide to clump, affecting its performance. 2. Suitable Temperature: The recommended storage temperature is 5°C - 30°C. Excessively high temperatures can accelerate product …

The process of aggregating colloidal particles and tiny suspended solids in water through some method (such as adding chemicals). Coagulation includes two processes: coagulation and flocculation. Coagulation mainly refers to the process in which colloids destabilize and form tiny aggregates, and flocculation mainly refers to the process in which destabilized colloids or tiny suspended solids …

(1) Expanded sludge The performance of activated sludge settling and flocculation can be understood by measuring the sludge volume index (SVI). Generally, the sludge volume index (SVI) is above 200mL/g, and the concentration of the sludge layer in the graduated cylinder changes from 5g/L to pressure. The dense phase sludge is called bulking sludge, one …

Biological contact oxidation method The biological contact oxidation method is used to treat wastewater, that is, the biological contact oxidation process is used to fill the biological reaction tank with fillers. The oxygenated sewage immerses all the fillers and flows through the fillers at a certain flow rate. The filler is covered with biofilm, and …

Activated sludge is a floc with strong adsorption and decomposition capabilities. The core of activated sludge lies in the word "living". As we all know, natural rivers have self-purification functions. This is because a group of microorganisms live in the water. The microorganisms eat the pollutants, so the water body will return to cleanliness. Therefore, …
