Research Project: Regeneration of Phosphorus Sorbing Materials (PSMs) toward Sustainable P Removal from Agricultural Runoff and Tile Drainage

Location: National Soil Erosion Research

Project Number: 5020-12130-003-029-N
Project Type: Non-Funded Cooperative Agreement

Start Date: Mar 1, 2020
End Date: Aug 31, 2021

Objective:
1) Develop cost-effective and practical regeneration technologies for low-cost P sorbing materials (PSMs); and 2) Examine and optimize material properties for optimum performance of engineered polymers toward effective, long-lasting, reusable P removal.

Approach:
This research aims to develop efficient regeneration approaches to allow low-cost PSMs to be effectively regenerated for repeated usages. In addition, more expensive but much more durable and reusable engineered PSMs will be examined for their performance and feasibility to be adopted for large scale treatment of agricultural runoff. For these purposes: 1. One industrial by-product steel metal shavings and one commercially available, reusable iron-enhanced activated alumina will be tested for their ability to be regenerated for repeated usages. 2. Oxides will be deposited into granular activated carbon and anion exchange resins to achieve high dissolved reactive phosphorus sorbing capacity and kinetics, and with long life-times.
