Stanford researchers have developed a strategy for secondary wastewater treatment using a membrane-aerated biofilm reactor (MABR) design that enables the simultaneous removal of pollutants and recovery of potent greenhouse gas (N2O) emissions.
Stanford researchers within the Dionne Lab have developed a method to use copper titanium dioxide core-shell nanoparticles for the light driven production of green fuels or removal of contaminants in water.
Discrete water sampling is resource and time intensive. It also involves the need for the scientist with or without a vessel to be on site to take the discrete sample.
Wastewater treatment facilities commonly add chlorine or chloramines at the end of treatment as a final disinfectant. While effective, any wastewater must be dechlorinated before release to prevent killing aquatic organisms.
Stanford researchers in the Criddle lab have developed a novel anaerobic membrane bioreactor that enables high flux treatment of wastewater with greatly reduced energy costs.
Wastewater treatment is energy and cost intensive. Demand charges on electricity bills often account for a large share of electricity costs, creating strong incentives for shifting load peaks away from time-of-use periods.
Stanford researchers have developed a portable sensor device for rapid detection of heavy metal ions using a sulfidation process and concentrator for increased visual detection.
The Mauter group has developed a method for removing selenium ions from wastewater using direct electrochemical reduction (DER). Selenium species are released into aquatic environments through anthropogenic activities such as mining, agriculture, and power generation.
Stanford researchers have developed an efficient electrochemical pathway for hydroxyl radicals (*OH) production for advanced treatment trains for purification of municipal wastewater for potable reuse.
Researchers in Prof. Thomas Jaramillo's laboratory have developed an electrochemical method for local production of ammonia that simultaneously solves an environmental problem while also producing a valuable chemical product with a massive global market.
A team of Stanford engineers has developed an efficient battery that can convert salinity gradient power (a.k.a. “blue energy”) into electricity using low-cost, non-toxic electrode materials.
Stanford researchers have invented a fully water-soluble, orange hydrazine sensor that can robustly quantify the toxin hydrazine in liquids such as drinking water, waste water (treated and untreated), and bodily fluids.
Stanford researchers have developed SCOA-DUPI (Simulation-based Control Optimization Algorithm with Dynamic Uncertain Parameter Inversion), which relies on real-time data collected though embedded sensors that can be used to ease the operational challenges of Managed Aquifer R
