Stanford researchers have developed a non-invasive seismic sensing method to monitor groundwater and subsurface pressure changes at multiple depths using passive ground vibration data.
Stanford researchers have developed an "electrocatalyst-in-a-box" that extracts wastewater nitrate and converts it into ammonia. Nitrogen pollution threatens water security and human health, and demand for ammonia continues to grow.
Stanford researchers developed an electrochemical reactor process that combines electrodialysis and membrane stripping, reduces the chemical inputs needed and expands recovered product portfolio to alkaline ammonia (for cleaning products) in ratios customized to a user's speci
Stanford researchers have developed an Electrodialysis and Nitrate Reduction Process (EDNR) that produces high-purity ammonia from agricultural runoff.
Stanford researchers in the WE3 and S3 Labs developed software for biogas modeling suitable for real-time, co-digestion forecasting control for waste streams with widely varying biodegradability rates.
Stanford scientists have developed a platform that combines Raman spectroscopy, nanomaterials, and machine learning to rapidly identify bacteria in wastewater without chemical labels.
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 WE3 and S3 Labs developed a cloud-based computation and predictive control platform for wastewater treatment facilities energy storage and energy generation. Wastewater treatment is energy and cost intensive.
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.
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.
