Frequently Asked Questions

Here are some quick answers to common questions about APS polymers, flocculants, and stormwater testing. For more details, visit our full FAQ page.

What does Applied Polymer Systems (APS) do?
APS develops and supports polymer-based solutions for erosion and sediment control during construction.

🔗 Learn more about APS
What makes APS different from other erosion control suppliers?
APS focuses on testing, technical support, and correct polymer selection rather than one-size-fits-all products.

🔗 APS technical support approach | Polymer performance testing
Who typically works with APS?
APS works with engineers, contractors, inspectors, and regulators involved in construction-phase stormwater compliance.

🔗 Industries served

What are flocculants?
Flocculants help fine sediment particles bind together so they can settle and be captured within BMPs (Best Management Practices).

🔗 Learn more about flocculants
Why are flocculants used in construction stormwater management?
They address fine silts and clays that traditional sediment controls struggle to capture.

🔗 Fine sediment and turbidity control solutions
Do flocculants replace erosion and sediment controls?
No. Flocculants enhance the performance of BMPs, not replace them. They work best in combination with properly designed and maintained basins, ditches, and inlet protection.
What is APAM?
APAM stands for Anionic Polyacrylamide, a polymer flocculant commonly used in construction stormwater applications.

🔗 Anionic PAM overview
Is all APAM the same?
No. Molecular weight and charge density vary, affecting how the polymer interacts with different soils.

🔗 Polymer selection and matching

Why does the charge of a flocculant matter?
Polymer charge affects how it interacts with sediments and aquatic life.

🔗 Polymer chemistry and performance
Why is anionic PAM preferred for stormwater applications?
Anionic PAM carries a negative charge that does not readily bind to fish gills or aquatic organisms when used correctly.

🔗 Environmental considerations for polymer use
Why are cationic polymers not used in construction stormwater?
Cationic polymers carry a positive charge and can bind strongly to fish gills, making them unsafe for stormwater applications.

🔗 Proper polymer selection guidance
How does APAM reduce risk to aquatic life?
When properly tested and applied, APAM binds fine sediment particles together so they settle and can be captured within BMPs, reducing turbidity and minimizing interaction with aquatic organisms downstream.
