APS Polymers and Floc Logs
APS polymers and Floc Logs reduce turbidity by binding fine particles, improving water quality in stormwater and construction runoff.
Stormwater leaving an active site often carries fine suspended particles that do not settle on their own. These colloidal clays and micro-sized sediments increase turbidity, reduce downstream clarity, and create compliance and environmental concerns. APS polymers and Floc Logs address this challenge by binding fine particles together so they settle, forming clearer discharge water that protects receiving streams, infrastructure, and regulatory standing. Nexterra supplies APS water clarification products that perform reliably across varied soils, site conditions, and flow regimes.
Polyacrylamide Soil and Water Treatments
Reliable turbidity control begins at the water and soil interface. APS polyacrylamides are designed to encourage fine particles to bond and settle, supporting both erosion control and water clarification in runoff environments that traditional filtration cannot handle alone. These formulations are soil-specific, organic, and non-toxic when used correctly, providing clarity improvements without disrupting biological site processes.
The performance benefits of APS polyacrylamides include:
- Targeted soil compatibility across a broad range of fines and clay materials, allowing formulations to match specific regional or site-based sediment characteristics.
- Strong particle attraction that draws suspended fines out of the water column, improving clarity and supporting downstream stabilization and infiltration performance.
- Versatile application methods that integrate with hydroseeding, watering programs, inlet protection strategies, and full-basin treatment plans.
These soil and water treatments provide a dependable foundation for turbidity control, helping stormwater move from active construction environments into downstream systems with improved clarity and reduced environmental impact.
APS 700 Series Floc Logs
Floc Logs extend the performance of polyacrylamide systems into flowing channels and basin environments where water needs treatment as it moves. Placed in ditches, inlet zones, channels, or structured treatment pathways, Floc Logs interact with passing runoff, binding fine particles into heavier clusters that settle out naturally.
The advantages of APS 700 Series Floc Logs include:
- Water-activated flocculating agents release steadily as runoff passes, delivering continuous turbidity reduction across swales, ditch lines, sediment basins, and overland flow paths without requiring mechanical dosing or onsite adjustment.
- Clarification performance remains consistent through shifting storm intensities, helping sustain water quality during both low-flow conditions and high-velocity peak events when fine particles are most difficult to control.
- More than sixty targeted formulations allow precise alignment with regional soil chemistry, matching clay behavior, mineral content, pH dynamics, and suspended fine characteristics to achieve efficient, predictable particle binding.
- Improved settling efficiency increases basin performance and reduces the frequency of dredging, sediment removal, and mechanical cleanouts, lowering long-term maintenance costs while preserving system capacity over the life of the project.
By treating stormwater as it moves rather than only after it settles, Floc Logs help maintain water clarity across both transitional and final discharge locations.
Upstream and Downstream Continuity
Sediment control is most effective when treatment follows the entire movement of water, beginning where runoff forms and continuing through channel flow, basin retention, and eventual discharge. APS polymers and Floc Logs support this continuous pathway by binding fines at the surface, clarifying water during transport, and improving conditions in settling environments.
This continuity preserves stormwater function and discharge integrity, preventing performance loss even as basin levels fluctuate and flow rates change.
- Reducing sediment load at the source prevents accumulation in drainage networks and receiving waterways, helping maintain system capacity and water clarity from the outset.
- Maintaining discharge clarity through shifting rainfall intensity ensures that water quality performance remains stable rather than fluctuating with storm conditions.
- Preserving basin function by preventing excessive sediment buildup reduces the frequency and cost of mechanical cleanouts, extending the effective lifespan of basin infrastructure.
- Supporting erosion control by improving water quality and stabilizing soil surface conditions creates a more resilient, interdependent system that holds its integrity through ongoing weather cycles.
The result is a water management system that remains clear, stable, and resilient from the point of runoff generation to the final discharge location.
