How many types of Coagulant?

Organic Coagulants

1 Polydadmac (PDADMAC)

Polydadmac (PDADMAC) is widely used as a flocculant in drinking water treatment, wastewater treatment and mining processes. Through charge neutralization and adsorption bridging mechanisms, PDADMAC destabilizes and flocculates suspended particles and negatively charged aqueous substances in water. It has remarkable effects in decolorization, algae killing and removal of organic matter. Similarly, the PDADMAC with NSF certification can be used for drinking water treatment.

2 Polyamine (PA)

Poly(EPI-DMA), namely Polyamine (PA), is also an organic flocculant with excellent performance. When PA is used as a flocculant, its mechanism is electro-neutralization and adsorption bridging. Similarly, PA flocculants with NSF certification have a wide range of applications in drinking water treatment, especially with Polyaluminum Chloride (PAC).

Inorganic Coagulants

Inorganic flocculants are usually made of metal salts and have strong electrolytic reaction ability. When these flocculants dissolve in water, they release charged ions that neutralize the charge of the particles suspended in the water, thus encouraging the particles to aggregate into larger flocs. Common inorganic flocculants include Polyaluminum Chloride (PAC), Aluminum Sulfate, Ferric Chloride and so on.

Polyaluminum Chloride (PAC) is an efficient inorganic flocculant, which is widely used in water treatment. It can effectively remove suspended matter, colloidal matter and organic pollutants in water through powerful electrolytic action and excellent flocculation performance. Polyaluminum chloride chemical is suitable for the treatment of drinking water, industrial wastewater, sewage and swimming pool water, with the advantages of low dose, high efficiency and environmental friendliness.

Aluminium Chlorohydrate (ACH),

similar to PAC, has superior charge neutralization ability and is a powerful coagulant and flocculant.

Aluminum Sulfate (Alum): Alum is a traditional flocculant that has been used for decades. It is effective in treating drinking water and wastewater, but its use has declined due to the availability of more effective alternatives.

Ferric Chloride: This inorganic flocculant is commonly used in wastewater treatment plants. It also effectively removes phosphates and heavy metals from water.
