Why Polyacrylamide is highly recommended in wastewater treatment?

We’re a polyacrylamide factory in central China, for 26 years, we focus on producing the anionic and cationic polyacrylamide and non-ionic types, mainly used for wastewater treatment and sludge dewatering. Premium performance at competitive price.

Polyacrylamide is highly recommended in wastewater treatment due to its unique properties and effectiveness in various applications. Here’s why it stands out:

1. ‌Superior Flocculation Performance‌

Polyacrylamide is widely used as a flocculant in wastewater treatment. It works by causing smaller particles to coalesce into larger flocs, which can then be easily separated from water through sedimentation or filtration‌5. This process is crucial for removing suspended solids, organic matter, and even some heavy metals from wastewater.

2. ‌Biocompatibility and Safety‌

Unlike some chemical flocculants, polyacrylamide is non-toxic and non-biodegradable, making it safe for use in water treatment systems‌1. Its inert nature ensures minimal environmental impact, and it does not produce harmful byproducts during the treatment process.

3. ‌Versatility and Efficiency‌

Polyacrylamide is effective across a wide range of wastewater types, including industrial effluents and municipal sewage. It can be tailored to specific needs by adjusting its molecular weight and charge, enhancing its ability to target different pollutants‌5. This adaptability makes it a preferred choice for both large-scale and specialized treatment applications.

4. ‌Longevity and Cost-Effectiveness‌

Polyacrylamide-based treatments are known for their durability, often requiring less frequent reapplication compared to other flocculants‌1. This reduces operational costs and maintenance efforts, making it a cost-effective solution for long-term wastewater management.

5. ‌Environmental and Regulatory Compliance‌

With increasing regulatory scrutiny on water quality, polyacrylamide’s safety profile and efficiency help facilities meet stringent environmental standards‌3. Its use aligns with sustainable practices by enabling the recovery and reuse of treated water.

In summary, polyacrylamide’s combination of effectiveness, safety, and adaptability makes it a highly recommended choice for modern wastewater treatment systems.

PAC+PAM chemical———-PAC quality and price

Dear friends, this is Rita from a 26-year experienced Polymer factory in China, selling PAM +PAC chemicals for wastewater treatment.

Today I’d like to share some about PAC.

PAC products are widely used coagulant, but color, valid content may be varied at different price.

For the same industrial Grade, if the weight varies, then:

  • light cargo, valid content a bit lower, can only load 20-21 tons;
  • heavy cargo, valid content higher, can load 25-26 tons;
  • valid content differ will lead to more dosage of chemical; If you can accept this cost, then it’s ok to buy lower price products.
  • But for international business, the freight is expensive esp. for PAC chemical. In my view, it’s better to use high content chemical with more container loadability. Freight per ton V.S. chemical price margin per ton

For the PAC products, is it always better to have low basicity?

Today let’s talk about something about the basicity of Polyaluminum Chloride(PAC) products. We all know, for the PAC products, basicity is also an important element in determining the final price. Then is it always better to use the low basicity PAC?

Well, basicity should be determined based on the specific application scenario; there’s no absolute “high” or “low” for best. The following are key criteria for determining effectiveness:

Application Scenario Determines Advantages and Disadvantages
Wastewater Treatment:
Highly turbid wastewater (such as printing and dyeing, and chemical wastewater) is more suitable for products with higher basicity, as they offer a more effective flocculation effect.

Using high-basicity products for low-turbidity water (such as drinking water) may cause turbidity, so a low-basicity product should be selected.

Production Cost:
Higher basicity reduces raw material consumption and reduces production costs. However, drinking water-grade products have higher environmental requirements, which can increase raw material costs.

Industry Standard Reference: The basicity of industrial-grade polyaluminum chloride is typically around 85-90%, while that of drinking water-grade products is around 45-60%.

Selection Principles
Water quality determines salinity: For high turbidity water, choose a high-basicity PAC; for low turbidity or drinking water, choose a low-basicity PAC.

Economic Considerations: High-basicity PAC offers lower costs, but a balance must be struck between effectiveness and stability.

Experimental Verification: Before practical application, the optimal salinity should be determined through pilot tests to avoid theoretical deviations.
