This research investigates how the shape, size, and surface chemistry of carbon nanomaterials influence their ability to remove contaminants from complex wastewater. By systematically testing nanomaterial variations against pollutants such as microplastics and petroleum derivatives, it aims to establish design rules that enable more effective, real-world water treatment technologies.

This research develops biodegradable “living” water filters grown from kombucha cellulose membranes. Unlike conventional plastic filters, these biofilters can self-defend against harmful microbes and self-repair when damaged. The work aims to create affordable, sustainable, and effective water filtration systems that reduce plastic waste while improving access to clean drinking water.

This research improves iron oxide nanoparticles for pollutant removal by addressing aggregation issues. Using pectin surface modification, particularly low methoxyl pectin via functionalization, enhances stability and adsorption efficiency. The modified nanoparticles achieve up to 95% methylene blue removal, demonstrating a significant improvement for environmental remediation applications.

This research tackles removal of Bisphenol A from water using light-activated materials. By combining titania with a silica shell and a responsive polymer “gate,” the system adapts to changing conditions like pH and temperature, improving pollutant breakdown under visible light and enabling smarter, more efficient water purification.

This research explores biofiltration as a sustainable alternative to chemical water treatment. By supplying bacteria with nutrients like nitrogen and phosphorus, it improves removal of harmful organic matter. Results show a 20% efficiency increase, reducing chemical use and risks, and offering a cost-effective solution for safe drinking water worldwide.

This research tackles harmful cyanobacteria blooms that threaten drinking water. Using ceramic membrane filtration, it prevents toxin release by retaining intact cells. Improved cleaning methods with eco-friendly chemicals enhance membrane efficiency and longevity. The work aims to ensure safe water treatment as climate change increases the frequency and severity of algal blooms.

Traces of pharmaceuticals increasingly contaminate water through human use and improper disposal. This research studies advanced oxidation processes—using UV light, ozone, and hydrogen peroxide—to break down these persistent pollutants. Optimizing these treatments helps protect ecosystems and public health by ensuring clean, safe, pharmaceutical-free drinking water.

This research presents a simple, low-energy method to remove and destroy PFAS “forever chemicals” from water. By chemically transforming PFAS to behave less like soap, over 98% can be separated and fully degraded, offering a scalable and environmentally friendly solution to widespread drinking water contamination.

Urban farms in Baltimore need reliable irrigation water. This research tested harvested rainwater for E. coli, Listeria, and Salmonella, and evaluated two treatments: sand–iron filtration and peracetic acid sanitizing. Both reduced E. coli, and sanitizing eliminated Listeria. Produce remained contamination-free, suggesting treated rainwater is a viable supplemental irrigation source.
