The problem with phosphorus

Phosphorus is a critical nutrient for all forms of life. However, human activity introduces excess phosphorus from fertilizers and urban landscapes into our rivers and lakes.

While phosphorus is readily available to terrestrial plants, in aquatic systems its scarcity often limits growth. Too much phosphorus in these systems can lead to nuisance weed growth, fish kills, and harmful algal blooms.

How CAPTure™ works

Larger phosphorus removal systems can run into issues with installation size, costs, or maintenance in the case of media failure. CAPTure™ utilizes replaceable media within a series of filter vessels to overcome these issues.

Replaceable media enables a smaller installation footprint and associated costs while protecting against media failure. Replacing media at yearly intervals provides innate maintenance that prevents sedimentation or aggregation.

CAPTure™ versus other practices

Conservation practices have been reducing phosphorus for decades, but are generally focused on particulate phosphorus. Dissolved phosphorus has a bigger impact on aquatic systems and is more difficult to intercept.

CAPTure™ systems installed in the field have demonstrated up to 90% dissolved phosphorus reductions for single events, while lab testing has shown that 40-60% average long-term reductions can be expected.

The Compact Agricultural Phosphorus Treatment Structure, or CAPTure™, is a simple, modular technology solution for removing dissolved phosphorus from agricultural tile drainage and overland runoff before it discharges to local surface waters. A single CAPTure™ box can be installed to treat up to 25 acres, or multiple boxes can be installed in parallel to handle larger drainage areas.

The CAPTure™ team can help design an installation for almost any drainage situation. Contact us today to explore possibilities for your locations.
