Flocculant is a type of substance that can reduce or eliminate the precipitation stability and polymerization stability of dispersed particles in water, and make dispersed particles coagulate and flocculate into aggregates for removal.
 
Generally speaking, inorganic flocculants have the characteristics of easy availability of raw materials, simple preparation, low price, and moderate treatment effect, so they are used in water treatment.
 
According to chemical composition, flocculants can be divided into three categories: inorganic flocculants, organic flocculants and microbial flocculants.
 
Inorganic flocculants include aluminum salts, iron salts and their polymers.
 
Organic flocculants can be divided into anionic, cationic, non-ionic, amphoteric, etc.
 
According to their sources, they can also be divided into two categories: artificial synthetic and natural polymer flocculants .
 
Traditionally used inorganic flocculants are aluminum salts and iron salts.
 
Aluminum salts mainly include aluminum sulfate, alum, and sodium aluminate. Iron salts mainly include iron trichloride, ferrous sulfate and iron sulfate.
