APS pH Floc Log - Applied Polymer Systems, Inc

Applied Polymer Systems products harness the power of environmentally friendly materials to solve numerous water quality, erosion, and sediment challenges. Anionic polyacrylamide (PAM) is a polymer flocculant that can be used for a wide variety of erosion, sediment, and stormwater management applications. APS products bind, stabilize, and/or remove commonly problematic particles like sediment (clays, silt), metals, and nutrients to prevent erosion, clear water, and improve BMP performance. APS products are made and packaged in the United States, are drinking water quality (NSF/ANSI Standard 60 Certified), have been extensively toxicity tested by third party laboratories in accordance with EPA standards, and are safe for both terrestrial and aquatic organisms and environments.

Product Overview

APS pH Logs are water soluble floc logs that gently and passively decrease pH without dangerous acid feed systems or active treatment measures. APS pH logs work best to make small pH changes using food grade, gentle materials. APS pH logs are useful for construction, industrial, and mining applications, or any water that requires pH limits to be met for discharge.

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.

General Company and Approach

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.

Flocculants & Polymers

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 Anionic PAM Is Important

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.
