Different types of flocculants are utilized in many industries for waste and water treatment and separation processes of solid-liquid. As its huge demands it classified to some main types of flocculants which commonly used in industries based on the provided sources:
- Inorganic Flocculants: Inorganic salt are primarily aluminum and poly aluminum chloride (PAC) and iron salts FeCl3 , are widely used in many industries due to their effectiveness and broad applications.
- Organic Synthetic Polymer Flocculants: These type of flocculants needs a small dosage requirement, typically less than 2%, and are known for their superior ability to form large, strong flocs that are resistant to breaking. They are categorized into
- Anionic PAM
- Cationic PAM
- non-ionic PAM
- Composite Flocculants: this type is new type of flocculant which achieved by combine different flocculant types to overcome limitations of using a single flocculant. They are more effective in a wide range of conditions (pH salinity temperature …) and applications, offering good water purification and faster sludge removal performance. but, it has complex synthesis and its expensive production process caused they used as secondary pollution.
