Over the past several decades, the value of drinking water treatment residuals (WTRs), a byproduct of the coagulation process during water purification, has been recognized in various environmental applications, including sustainable remediation of phosphorus (P)-enriched soils. Aluminum-based WTRs (Al-WTRs) are suitable adsorbent materials for P, which can be obtained and processed inexpensively. However, given their heterogeneous nature, it is essential to identify an easily analyzable chemical property that can predict the capability of Al-WTRs to bind P before soil amendment. To address this issue, thirteen Al-WTRs were collected from various geographical locations around the United States. The non-hazardous nature of …

Soluble non-reactive nutrient species, i.e., dissolved organic nitrogen (DON) and soluble non-reactive phosphorus (sNRP), are not effectively removed and recovered. Unfortunately, the non-reactive species can cause eutrophication in receiving waterbodies. Thus, removal and recovery of soluble non-reactive nutrients is critical for reducing nutrient discharge and advancing the national goal of enhanced nutrient recovery. Transformation of non-reactive nutrients to more readily removable/recoverable species using ozonation and UV/H2O2 for enhanced nutrient recovery has been reported in literature. Electrooxidation (EO) may outperform these processes in transforming nutrients as EO can utilize multiple oxidation pathways, e.g., in-situ generated oxidants or direct electron transfer (DET). …
