Description and Purpose
PAM increases the soil’s available pore volume, thus increasing infiltration and reducing the quantity of stormwater runoff that can cause erosion. Suspended sediments from PAM treated soils exhibit increased flocculation over untreated soils.
The increased flocculation...
Polyacrylamide (abbreviated PAM), with the formula -[CH2CH]nCONH2-, is a polymer formed from the polymerization of acrylamide monomers.
Polyacrylamides are classified as non-ionic (NPAM), cationic (CPAM), anionic (APAM) and Amphionic (Amphionic PAM).
Polyacrylamide application:
Polyacrylamide...
1. Water treatment field
Water treatment includes raw water treatment, sewage treatment and industrial water treatment. It can be used in combination with activated carbon in raw water treatment to coagulate and clarify suspended particles in domestic water. If organic flocculant acrylamide i...
Polyacrylamide anions and cations are very different, they are polymer flocculants, anions and cations of their two different models, they can not be mixed, mixed use will react, lose the effect of the agent.
Anionic polyacrylamide is mainly used for flocculation, sedimentation and clarification of...
Acrylamide is a colorless crystalline chemical, an unsaturated amide, which is widely used in industry. It is also the main chemical raw material for the production of polyacrylamide, and is widely used in water purification treatment, pulp processing, pipeline coating and other industries.

PAM structural differences
Cationic polyacrylamide (CPAM): It is a linear polymer compound. Because it has a variety of active groups, it can form hydrogen bonds with many substances through affinity and adsorption. Mainly flocculates negatively charged colloids.
Anionic polyacrylamide...
Polyacrylamide is typically synthesized from raw materials that include:
1. Acrylamide Monomer: Acrylamide is the primary raw material used in the production of polyacrylamide. It is a small molecule consisting of a vinyl group (CH2=CH-) and an amide group (-CONH2). Acrylamide is derived from...
Polyacrylamide production in China is significant, and the country is one of the leading producers and consumers of polyacrylamide globally. China has a well-established chemical industry and a large market demand for polyacrylamide due to its wide range of applications.
Several factors contribute t...
Water treatment flocculants are chemical substances used to aid in the removal of suspended solids, organic matter, and other impurities from water during the clarification or filtration process. These flocculants promote the aggregation of fine particles into larger, settleable flocs, making it eas...
Polyacrylamide is widely used across various industries due to its versatile properties. Here are some of the widespread applications of polyacrylamide:
1. Water Treatment: Polyacrylamide is extensively used in water treatment processes. It acts as a flocculant and coagulant agent, aiding in the rem...
Polyacrylamide is a versatile water-soluble polymer that finds widespread applications in various industrial and environmental processes. It works primarily due to its high molecular weight and functional groups, specifically in terms of its ability to flocculate, or coagulate, particles and enhance...
The degree of hydrolysis of polyacrylamide refers to the extent to which the acrylamide monomers in the polymer have undergone hydrolysis. Polyacrylamide can be partially hydrolyzed, resulting in the formation of both acrylamide and acrylic acid units within the polymer chain.
The degree of hydrolys...
