Most stormwater treatments rely on settling or filtration to capture pollutants, allowing dissolved pollutants—like phosphates—to pass through untreated, ultimately causing eutrophication in lakes and rivers.
Join returning speaker and author Andrew Erickson to explore a new technology to capture dissolved phosphates—iron enhanced sand filtration (IESF), the laboratory results, field data, and the best practices to apply in your IESF design and maintenance.
In this webinar, we'll explore how to use iron enhanced sand filtration (IESF) as an effective method to capture dissolved phosphorus (phosphate) from stormwater. We'll start by outlining the key elements and treatment model of iron enhanced sand filtration, and explore how it captures phosphates through reactions to iron oxide. Erickson will then cover the laboratory results and field data from 30 years of simulated runoff volume and ~90 years of phosphate load experiments. Finally, we'll take a tour of three iron-enhanced sand filtration installations and monitoring projects (urban and agricultural), and Erickson will outline the resulting design, installation, and maintenance best practices to apply in your projects.
Attendees can expect the discussion and education of the following learning objectives:
- Learn how to use IESF as a stormwater treatment tool for capturing dissolved phosphorous
- Understand IESF key elements, design, and treatment model
- Gain the design, installation, and maintenance best practices for IESF installations
- Get the laboratory results and field data from 30 years of simulated runoff volume and ~90 years of phosphate load experiments, as well as three current installations.
