In-situ monitoring for the role of dye structure on electrochemical decolorization

The widespread use of synthetic dyes has led to the release of substantial amounts of dye-contaminated wastewater, posing significant environmental and health concerns. This study focuses on the use of anodic and electrochemically activated persulfate oxidation for the degradation of organic contaminants. Specifically, the structural variations of nine dyes in the indigoid and azo families, and their impact on the efficiency of electrochemical oxidation were analyzed. An in situ continuous monitoring apparatus with a UV-visible detector was employed to collect data in real-time.

Advanced PFAs Removal for Water Treatment

Puraffinity has developed Puratech, a patented solution designed to effectively remove PFAS (per- and polyfluoroalkyl substances) from water. Puratech uses advanced materials with high adsorption capacity, engineered through a proprietary multi-step process that enhances performance. This innovative technology offers superior PFAS removal compared to traditional petroleum-derived ion exchange resins and granular activated carbon, thanks to its broader-spectrum removal capabilities and faster kinetics.

Models to Predict the Removal of Emerging Micropollutants from Water by Novel Adsorbents in Fixed-Bed Column Processes

The U.S. Environmental Protection Agency (EPA), through the Innovative Water Technology Grant Program, is seeking applications for research to develop, test and deploy predictive models for novel adsorbents and estimate the effectiveness of these adsorbents to remove emerging micropollutants in drinking water and wastewater treatment operations.

TAML® Catalysis

A technology developed by Sudoc, a company that aims to replace toxic chemicals with toxin-free chemical options for wastewater disposal treatments. Sudoc specializes in TAML (Tetramic Acid Metal-Ligand) molecules to make chemical reactions exponentially more powerful. TAML® catalysis is characterized by premier catalytic functions with self-decomposing mechanisms. It is most environmentally effective when used with hydrogen peroxide -- a chemical made up of hydrogen and oxygen used by our bodies to oxidize toxic compounds and chemicals.

PhosRox™

Biodegradable sorbent that captures nutrients in water. Phosphorus and nitrogen are nutrients in water that act as fertilizers for aquatic plants. Eutrophication occurs when there is an overabundance of these nutrients. Nutrient pollution occurs when eutrophication produces an excessive amount of algae. These algae disrupt ecosystems by lowering the amount of dissolved oxygen in water, reducing water quality, turning the water green, causing a foul smell, blocking sunlight, and harming animals and humans who consume it.
