Phosphorus Management with Phoslock
The development of a Phoslock phosphorus mitigation program is based on the assessment
of site specific conditions such as water quality objectives, nutrient loading (internal
and external) and water quality and sediment conditions. There are two general categories
of Phoslock programs developed waterbodies:
Recovery Solution: Begin the water quality recovery
process through strategic applications of Phoslock to remove targeted levels of
FRP from the water column. This solution may also be rotated with SePRO algaecide
applications as needed.
Reset Solution: Reset the ecological clock/trophic
status and restore water quality by implementing a Phoslock program to remove a
targeted quantity of FRP from the water and sediments. Project planning begins with
assessment of water and sediment parameters (laboratory and field analysis) and
nutrient budget modeling to allow for development of a custom Phoslock prescription.
Application strategies may include a one-time application or a sequential application
strategy over time based on site-specific conditions and management objectives.
Phoslock, coupled with SeSCRIPT analytical services, provides a comprehensive assessment,
prescription and implementation system for removing phosphorus and restoring water
