Polyacrylamide – PAM - Water Treatment Agents
Polyacrylamide(PAM), often referred to as “polymer” or “flocculant”. It is a long chain, linear organic polymer made up of individual monomer units with the molecular formula of C3H5NO and molecular weights ranging from 3,000,000 to 30,000,000 Daltons. PAM is a dry white or light yellow powder similar in shape to table salt.
In the treatment of the domestic sewage, there are two types of the water flocculants: the PAM (Polyacrylamide) and the PAC (Polyaluminium Chloride). The domestic sewage is the waste water which is directly discharged by the residents in the daily life, the major component is the stool and the washing waste water.
Application of polyacrylamide flocculants for water treatment
Polyacrylamide (PAM) is a water-soluble polymer that is widely used as a flocculant in sewage treatment. The accumulation of PAM affects the formation of dewatered sludge and potentially produces...
PAM polyacrylamide and its application in water treatment The polyacrylamide (PAM) has a very important role in the field of water treatment. In our country is very poor water resources area, average annual water resources total 2.8 trillion cubic meters, ranking sixth in the world, but the amount per capita only 271 cubic meters, equivalent to the world average amount per capita quarter, ranking No. 88 in the world.
How the PAM works with PAC in water treatment - Polyacrylamide
One kind usually when sewage treatment flocculants, some water, a single effect is not up, you must use the combination of the two, in the use of inorganic flocculants PAC and polyacrylamide flocculant sewage treatment complex will achieve better results but when a drug-free to pay attention to the order, the order is not correct, but also reach the effect.
High molecular weight (10 6 –3 × 10 7 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction...

Cationic polyacrylamide(PAM) is most often used to increase the viscosity of water (creating a thicker solution) or to encourage flocculation of particles present in water and allow rapid settlement of finely suspended solid
Anionic polyacrylamide(PAM) for water treatment
Anionic polyacrylamide, is a white powder water -soluble polymer with varying molecular weight and charge density. It generate a good flocculation and can decrease the resistance between liquids. It is most often used to increase the viscosity of water (creating a thicker solution) or to encourage flocculation of particles present in water and
Polyacrylamide and its co-polymers are used as flocculants or coagulants in industrial wastewater treatment .Homo-polymer is used in this application and can be either nonionic, cationic or

These results suggest that the use of PAM reduces the amount of flocculant required for the treatment and lowers the cost of the coagulation–flocculation process. The optimum dosages obtained by the C-PAM are 3.5 mg l −1 with Organopol 5415 and Chemfloc 1515C (92% of COD reduction) and 10 mg l −1 with Organopol 5020, Organopol 5470 and
- Can polymeric iron sulphate be used for industrial effluent treatment?
- The combination of PFS with other chemicals or natural coagulants has high potential in treating water or wastewater. This is due to their greater effectiveness and cheaper cost compared to inorganic coagulants and organic flocculants . Previous studies of composite polymeric iron sulphate for different industrial effluent treatments
- Does polyferric sulphate remove algae?
- Preparation and uses of polyferric sulphate, US Pat., 5,785,862, 1998. Search in Google Scholar Jiang, J. Q., N. J. D. Graham, and C. Harward. Comparison of polyferric sulphate with other coagulants for the removal of algae and algae-derived organic matter.
- Why are PFS coagulants better than ferric sulphate?
- Therefore, as the PFS coagulants consist mainly of polymeric species, they exhibit better coagulation behaviour. It is worth noting that for a 90% removal efficiency, only 20 mg/l of PFS are required, whereas the respective dosage of ferric sulphate in this case is much higher, i.e. 30 mg/l.
- How effective is PFS in removing phosphate ions from municipal wastewater?
- PFS is highly efficient in removing the phosphate ions from biologically pre-treated municipal wastewater. Moreover, PFS samples exhibit a significantly better coagulation performance, than the respective conventional coagulant, i.e. ferric sulphate, in treating such a wastewater under the applied experimental conditions.
