Commonly used water treatment approaches to mitigate phosphorus pollution and its consequences in small watersheds include the use of chemicals to precipitate phosphorus or algaecides to terminate algal growth. Both approaches require the addition of chemicals to the waterbodies resulting in biomass/sludge build-up, solid precipitates and/or potential toxicity from added metal salts. There is a hi ...

Suspended ceiling tiles are widely used in commercial and residential construction because they offer flexibility and easy access to utilities. Most of the available tiles absorb water, resulting in sagging, staining, and mold/mildew growth. They also contain potentially hazardous chemicals and release airborne fibers when broken or cut. Existing tiles are not durable, requiring frequent replaceme ...

In 2011, there were 60,000 dairy farms in the US. Of there, 56,600 had herds of fewer than 500 animals. Currently, manure digester installations are only considered economical for herds of at least 500 animals. There require turbine or diesel generator sets of 100 Kilowatt size and larger. The need exists for a smaller waste to energy conversion approach for implementation on small farms were ...

In this program, we will develop a breakthrough technology that will enable wafer-scale epitaxial lift-off (ELO) of GaN power device heterostructures from low-dislocation-density bulk GaN substrates. This technology will be used to provide a low-cost vertical junction field effect transistors (VJFETs) with high breakdown voltage (greater than 1,200 V) and high current capability (greater than 100 ...

This Small Business Innovation Research (SBIR) project will employ Nanofiltration to generate sulfate ion feedstocks and high current density on-site generation (synthesis) of the powerful oxidant peroxodisulphate (“persulfate”) with novel, high reliability boron-doped untrananocrystal-line diamond (UNCD) electrodes to dramatically lower the cost of unconventional fossil fuel (FF) waste water ...

Onsite wastewater systems are a significant source of nutrient loading to the environment and there is a demand for technologies that remove nutrients at the source. Most desired are passive, low cost systems that can consistently remove ninety percent or greater nitrogen while having low energy input and easy operation. While numerous proprietary devices have been developed that typically emplo ...

A team of EP Purification and the University of Illinois engineer and chemists is pursuing the commercialization of low cost microchannel plasma modules capable of efficiently producing ozone for water treatment. The conservation of water resources for human consumption is a growing national priority. Contamination of ground municipal water by animal manure, fertilizer and pharmaceuticals, for e ...

The Phase II project will be dedicated to the design, creation and full-scale testing of a functional multi­-specific sensor prototype for real-time environmental water monitoring. The sensor will be miniature, portable, robust, easy-to-use and completely field-deployable. The utilized competitive displacement detection scheme guarantees high specificity as was shown in Phase I, while bright fluo ...

In most critical software systems, a state that is partially visible through values passed across interfaces contains information that could determine the health of the software system, and whether a failure is likely in the future. Some of this information behaves in a continuous fashion, e.g., the available memory or disk space is easily interpreted to monitor system health. Other values are nom ...

"At 2.7 million miles of paved roads, the United States has the largest network of roads in the world. The mainstream approach to pavement rehabilitation has been to mill the deteriorated asphalt and replace with new asphalt mix. The hot in-place pavement recycling process has the potential of replacing the milling and resurfacing process with substantial financial and environmental savings. Ho ...
