Polyacrylamide (PAM) is a linear polymer. It has the characteristics of high molecular weight (8-18 million), good water solubility, and strong flocculation ability. Its efficient flocculation performance can quickly settle suspended particles through electric neutralization and adsorption bridging, salt and acid resistance (pH 3-10 stable), low residue, and environmental safety (in accordance with REACH/ISO standards). It is widely used in industrial wastewater treatment (sand washing, papermaking, printing and dyeing), municipal sludge dewatering, mining tailings settling, and oil recovery thickening.

Dissolve configuration
It is recommended to prepare a 0.1% -0.3% aqueous solution (1-3kg/ton of water) and slowly add the powder under stirring conditions to avoid clumping. Continue stirring for 40-60 minutes until completely dissolved, and let it stand for 30 minutes for better results.
Investment method
Inject the solution into the sewage reaction tank through a metering pump, or use it in combination with inorganic coagulants (such as PAC) first. For high turbidity wastewater, the dosage can be appropriately increased by 20% -30%, and the mixing sequence can be adjusted according to the actual water quality.
Recommended dosage
Municipal sewage: 2-5g/ton; Sand washing/mining wastewater: 5-10g/ton; Paper making/printing and dyeing wastewater: 3-8g/ton; Food processing wastewater: 1-3g/ton (requiring food grade products). The specific dosage needs to be determined through small-scale testing to determine the optimal value.
Precautions
Avoid direct mixing with high priced metal salts, and dissolve at a water temperature not exceeding 60 ºC. Store in a dry and cool place, seal and prevent moisture after opening. It is recommended to use the solution within 24 hours to ensure effectiveness.
Application and advantages
Efficient water treatment
Application: Widely used in industrial wastewater treatment (such as electroplating, printing and dyeing, papermaking) and municipal wastewater treatment, quickly floccules suspended solids, and improves water quality clarity.
Advantages: Strong adsorption bridging ability, fast settling speed, significantly reducing sludge moisture content.
Mining tailings dewatering
Application: Suitable for mining washing, tailings concentration, accelerating solid-liquid separation, and improving the utilization rate of return water.
Advantages: Resistant to high salt, acid and alkali, adaptable to complex slurry environments, and reduces metal loss.
Oil extraction and oil displacement increase efficiency
Application: As a tertiary oil recovery and displacement agent, it increases the viscosity of injected water and improves petroleum recovery rate.
Advantages: Adjustable molecular weight, strong shear resistance, and effective expansion of oil displacement area.
Paper and textile auxiliaries
Application: Used as a retention aid in papermaking and to remove color from wastewater in textile printing and dyeing.
Advantages: Low residue, avoiding equipment blockage, improving product whiteness and uniformity
Food grade environmental protection treatment
Application: Purification of food processing wastewater, some high-purity models can be used for drinking water treatment.
Advantages: FDA/NSF certified, non-toxic and residue free, safe and reliable.

Q1:What is the application area of your product?
A:They are mainly used for water treatment, such as textile, printing, dyeing, papermaking, mining, ink, paint, etc.
Q2:What should be noted when storing PAM?
A:Moisture proof sealed storage, avoid direct sunlight (shelf life of 2 years).Anionic/non-ionic PAM is acid and alkali resistant, while cationic PAM should avoid long-term contact with iron containers.
Q3:How to judge the quality of PAM?
A:It can be verified through the following indicators:
Molecular weight: The higher the molecular weight, the stronger the flocculation ability (our APAM molecular weight can reach over 18 million);
Dissolving speed: High quality PAM dissolves without particles or wire drawing;
Flocculation effect: Take a small sample of wastewater and observe the size and settling speed of flocs.
Q4:What is your minimum order quantity?
A:Usually 1 MT, but for trial orders, the acceptable quantity is relatively small. The price of large orders can be discounted.
Q5:Do you provide free samples?
A:Free samples are open for collection, and you only need to be responsible for the transportation process (mailing or self pickup).
