"Application of Polyacrylamide-based Floc Logs
Runoff waters generated on highway construction sites can have turbidities in excess of the proposed EPA regulatory standard of 280 NTU due to large areas of exposed soil. The objective of this research was to develop best management practices (BMPs) for the use of anionic polyacrylamide (PAM) based Floc Logs, for turbidity control. Five commercially available types of PAM-based Floc Logs were

APS 700 Series Floc Logs® Applied Polymer Systems, Inc
APS 700 Series Floc Logs are a group of semi-hydrated anionic polyacrylamide blended logs that when placed in the flow of turbid water remove fine particles and reduce turbidity, metals and inanimate nutrient values. Each Floc Log is formulated for the soil and water chemistry of the specific site where the placement and usage are intended.
APS Floc logs consist of semi-hydrated, polyacrylamide blended blocks that are used to reduce turbidity through flocculation. The polymer from the log interacts with fine sediments and soil particles that have become suspended within the water. The logs are soil-specific and require testing of interaction between the log and the turbid water.

Polyacrylamide Erosion Control Applicator Log. APS 700 Series Floc Log ® is a group of soil specific tailored log-blocks that contains blends of water treatment components and polyacrylamide co-polymer for water clarification and erosion control. They reduce and prevent fine particles and colloidal clays from suspension in stormwater.

Floc logs are a form of passive application. They are relatively low in cost and release PAM upon saturation. However, the amount of PAM released cannot be controlled, resulting in the under- or over-application of PAM to the water. Another drawback of floc logs is that they dry out between runoff events and the release
Floc Logs are placed at strategic points where a site’s runoff can be directed to flow over them. The Floc Log is designed to be able to treat water at a base flow rate of 50 to 75 gallons per minute. Once situated and in contact with water, the Floc Logs slowly dissolve releasing minute quantities of matter that convert colloidal suspen-
- Can polymer materials be used as water soluble flocculants?
- Our review indicates that there has been a large body of literature in the recent years focusing on introducing new polymer materials as water soluble flocculants for a variety of applications including wastewater treatment, mineral processing, and oil sands tailings treatment.
- Can biopolymer-based flocculants reduce water treatment risk?
- As biopolymer-based flocculants are of great benefit to reduce the risk of water treatment, researches of new flocculants based on biopolymers are the focus of scholars in recent years. Biopolymer-based flocculants have the potential to scale up practical applications.
- Which polymers are effective flocculants and adsorbents?
- Synthetic polymers such as polyacrylamide, polyacrylic acid, and polystyrene sulfonic acid, which are soluble in water, have been employed as effective flocculants and adsorbents.
- What is a polymer flocculant?
- Among the synthetic polymer flocculants, the most important is water-soluble polyacrylamide (PAM)—a non-ionic, amorphous polymer which can be modified to ionic form in the copolymerization process [ 8, 9, 10 ]. The acrylamide monomer can be used for grafting or crosslinking of other type of polymers.
