Agricultural runoff treatment

 

Capture phosphorus in drainage and runoff before it reaches receiving waters. Poseidon Pellets bring phosphate-bearing water into contact with contained media in a planned treatment step.

 

Start with the drainage route

Identify where runoff collects, how flow changes during rainfall, and where media can be inspected and retrieved. Boom socks or an engineered media bed may fit different sites. Allow for sediment, debris, bypass flows, and safe access.

 

Understand the nutrient load

Use measured flow and laboratory results to estimate phosphate loading. Check whether results report phosphorus as P or phosphate as PO4. The two reporting bases use different mass values, so keep calculations consistent.

 

Test treatment on site water

Contact time, media volume, phosphate concentration, and water chemistry all affect performance. Compare inlet and outlet samples under representative conditions. Monitor the used media and plan replacement around the treatment target.

 

A circular route for recovered phosphorus

Phosphorus is a nutrient plants need. After capture from water, used Poseidon Pellets can be evaluated for reuse as a slow-release soil amendment or fertilizer. Testing with corn and fescue by the USDA National Soil Erosion Research Laboratory demonstrated positive agricultural reuse potential. Suitability for a particular site depends on source water, used-media testing, and local requirements.
