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 700 Series BioBlend Floc Logs are a group of soil-specific, tailored gel logs that contain blends of anionic plant-based biopolymers and polyacrylamide for water clarification. They remove fine suspended particulates such as silt and clay from water and are safe for the environment and sensitive aquatic organisms. BioBlend Floc Log has the effectiveness of traditional Floc Logs but incorporates sustainable and rapidly degradable plant-based polymers.

Primary Applications

  • Mine tailings and waste pile ditches
  • Stormwater drainage from construction and building sites
  • Road and highway construction runoff ditches
  • Ditch and treatment system placement for all forms of highly turbid waters (less than 4% solids)
  • Dredging operations as a flocculent

Features and Benefits

  • Removes solubilized soils and clay from water
  • Prevents colloidal solutions in water within ditch systems
  • Binds cationic metals within water, reducing solubilization
  • Binds pesticides and fertilizers within runoff water
  • Increases soil permeability and water penetration to shallow plants in ditches
  • Reduces operational and cleanup costs
  • Reduces environmental risks and helps meet compliance.

Specifications / Compliances

  • ANSI/NSF Standard 60 Drinking water treatment chemical additives
  • 48h or 96h Acute Toxicity Tests (D. magna or O. mykiss)
    7 Day Chronic Toxicity Tests (P. promealas or C. dubia

Packaging

APS 700 Series Floc Logs are packaged in boxes of four (4)

Technical Information

  • Appearance – semi-solid block
  • Biodegradable internal coconut skeleton
  • Percent Moisture – 40% maximum
  • pH 0.5% Solution – 6-8
  • Shelf Life – up to 5 years when stored out of UV rays

Placement

Floc Logs are designed for placement within ditches averaging three feet wide by two feet deep. Floc log placement is based on gallon per minute flow rates.

Note: actual GPM or dosage will vary based on site criteria and soil/water testing.

Directions for Use

(Water and Floc Log Mixing is Very Important!)

  • APS 700 Series Floc Logs should be placed within the upper quarter to half of a stabilized ditch system or as close as possible to active earth moving activities. Floc Logs have built in ropes with attachment loops which can be looped over stakes to ensure they remain where placed. Mixing is key! If the flow rate is too slow, adding sand bags, cinder blocks, etc., can create the turbulence required for proper mixing.
  • Floc Logs are designed to treat dirty water, not liquid mud; when the water contains heavy solids (exceeding 4%), it will be necessary to create a sediment or grit pit to let the heavy solids settle before treating the water.
  • Floc Logs must not be placed in areas where heavy erosion would result in the Floc Logs becoming buried. Where there is heavy sedimentation, maintenance will be required.
  • APS 700 Series Floc Logs can easily be moved to different locations as site conditions change. Water quality will be improved with the addition of a dispersion field or soft armor covered ditch checks below the Floc Log(s) to collect flocculated particulate. Construction of mixing weirs may be  equired in areas where short ditch lines, swelling clays, heavy particle concentrations, or steep slopes may be encountered.

Cleanup

Latex or rubber gloves are recommended for handling during usage. Use soap and water to wash hands after handling.

Precautions / Limitations

  • APS 700 Series Floc Logs are extremely slippery when wet.
  • Clean up spills quickly. Do not use water unless necessary as extremely slippery conditions will result and if water is necessary, use pressure washer.
  • APS Floc Log will remain viable for up to 5 years when stored out of UV rays.
  • APS 700 Series Floc Logs have been specifically tailored to specific water and soil types and samples must be tested. Testing is necessary and is free.

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.

    🔗 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.
