Polyacrylamide (PAM), a truly extraordinary linear polymer, is a standout performer in the realm of wastewater treatment, thanks to its exceptional attributes. Boasting a high molecular weight that spans from 8 to 18 million, PAM exhibits outstanding water solubility and exceptional flocculation capabilities. Its prowess in enabling the rapid settlement of suspended particles is achieved through mechanisms such as electric neutralization and adsorption bridging. This versatile polymer demonstrates remarkable resilience in various environments, offering salt and acid resistance with stable performance across a wide pH range of 3-10. Crucially, PAM is environmentally friendly, meeting rigorous REACH and ISO standards to ensure minimal residue and seamless integration with ecological systems. Its applications are vast and diverse, playing essential roles in industrial wastewater treatment processes, including sand washing, papermaking, and textile printing and dyeing. PAM's utility further extends to municipal sludge dewatering, the effective settling of mining tailings, and enhancing oil recovery through thickening. Discover the transformative power of PAM-your pathway to efficient and eco-conscious wastewater treatment.
PAM can be elegantly classified into four categories based on its ionic properties:
| Anionic polyacrylamide |
Carrying negative charge, suitable for flocculation and sedimentation of high suspended solids wastewater, such as mining tailings treatment. |
| Cationic polyacrylamide |
Carrying a positive charge, mainly used for sludge dewatering and organic wastewater treatment. |
| Non-ionic polyacrylamide |
Non charged, suitable for acidic or high salt wastewater systems. |
| Amphoteric ion polyacrylamide |
Simultaneously containing positive and negative charges, used for complex water quality conditions. |
The Core Characteristics of PAM
Efficient Flocculation: Through the remarkable effects of "adsorption bridging" and "charge neutralization," suspended particles are rapidly aggregated to form cohesive flocs.
Solubility: It requires dissolution in cold water, with higher molecular weights resulting in longer dissolution times, typically ranging from 30 to 90 minutes.
Stability: The performance remains stable within the pH range of 3-10, although degradation occurs at high temperatures (>60 ºC) or in the presence of strong oxidants.
Safety: The polymer itself is non-toxic, but careful control of the residual monomer PAM amount is necessary, keeping it below 0.05%.

Dissolve configuration
To achieve unparalleled efficiency in wastewater treatment, we recommend crafting a 0.1% - 0.3% aqueous solution. This is done by dissolving 1-3kg of our top-tier Eco-Friendly Rapid Settlement Flocculant per ton of water. Introduce the powder gently while ensuring a constant stir to avoid any clumps. Maintain stirring for 40-60 minutes to guarantee complete dissolution. For enhanced performance, let the solution rest for an additional 30 minutes to fully unleash its power.
Investment method
For precise and effective treatment, administer the prepared solution into the sewage reaction tank using a metering pump to ensure uniform distribution. For superior results, consider pre-mixing with inorganic coagulants like PAC before application. In instances of high turbidity wastewater, a dosage increase of 20% - 30% may be beneficial. Tailor the mixing sequence in response to the water quality observed, ensuring optimal outcomes every time.
Recommended dosage
When addressing municipal sewage, apply 2-5g per ton for optimal results. Sand washing or mining wastewater demands 5-10g per ton. For paper manufacturing, along with printing or dyeing wastewater, employ 3-8g per ton, while food processing wastewater requires 1-3g per ton using food-grade variants. Small-scale testing is essential to pinpoint the exact optimal dosage, finely tuned to your distinct requirements.
Precautions
Prioritize safety and effectiveness by avoiding direct mixing with high-priced metal salts. Dissolve the product at water temperatures not exceeding 60 ºC. Store it in a cool, dry place, ensuring it is tightly sealed after opening to avert moisture exposure. For peak performance, utilize the prepared solution within 24 hours to maximize its potent effectiveness.
