1. Anionic polyacrylamie, It is the white powder. The APAM with the molecular weight of 4 -22 million has good water solubility, and it can be dissolved in water by arbitrary proportion but not in organic solvents. It has the characteristics of high-polymer electrolyte in the neutral and alkaline medium, and it is sensitive to the electrolyte salt. And it can be cross-linked into insoluble gel with the high valence metal ions.
Use:
(1) Industrial waste water treatment:
For the neutral or alkaline waste water with pH value of 7-14, large suspended particles and ions of positive charge, it has the best treating effect, such as the waste water from iron industry, electroplating factory, metallurgical industry, coal washing, etc..
(2) Drinking water treatment:
When the drinking water still does not meet the standard after the treatment of the precipitation and filtering, then the APAM can be used as the flocculant. Its dosage is 2%-5% of that of the inorganic flocculants, but the effect of former is dozens of times of that of latter.
(3) It can be used for the recycling of the loss of brewers' grains in the alcohol plant and starch in the starch factory.
(4) It can be used as the water block agent in the oil field, and also the oil-displacing agent during the tertiary recovery.
(5) It can be applied in the paper-making industry. It can be used as the dispersant, retention aid, etc. in the long fiber paper-making, and also the flocculant for the waste water from the paper-making.

2. Cationic polyacrylamide is the white powder with the molecular weight from 5million to 18 million The CPAM with the icon degree from 20% to 80% has good water solubility, and it can be dissolved in the water by the arbitrary proportion but not the organic solvent. Besides, it has the characteristics of high-polymer electrolyte, and it can be applied in the treatment of waste water rich in organics with negative charge.
Use: (1) Sludge dewatering.
(2) Domestic and organic water treatment: It is positive in charge in the acid, neutral and alkaline medium.
(3) The intensifier in the paper –making industry.
(4) It can be used as the additive chemicals in the oil field.

1. Industrial Waste Water Treatment
It has the best effect in particular in processing sewage water with suspended particulate,thicker size, high concentration, positive charge particle, neutral or alkalescence water PH value,
waste water of iron and steel plants, waste water of electroplating factory, metallurgy waste water,
coal washing waste water and other waste water.
2. Drinking Water Treatment:
Water sources of many tap water factories in China come from rivers, the sand and mineral
contents are higher, water is muddy, the water still can not achieve demands although passing
through sedimentation and filtration, and flocculating agent needs adding; however huge adding
amount generates increased mud amount and bad effect. The adding amount is only 1/50
of inorganic flocculating agent if anionic-polyacrylamide is adopted as flocculating agent, but the
effect is several times better than the organic flocculating agent, and even dozens of times.
If the river water with severe organic matter pollution can be matched with anionic-polyacrylamide
for use, the effect will be better.
3.As a flocculating agent:
Mainly used in industrial solid-liquid separation process, including settlement,
to clarify,concentrate and sludge dewatering processes,applications for all the major sectors are: urban
sewage treatment.Paper plant ,food processing,petrochemical,metallurgical, processing, dyeing and the
sugar and all kinds of industrial wastewater treatment.
