Ozone treatment of wastewater to destroy organic contaminants prior to discharge into the environment is an extremely effective advanced oxidation technology. To date the use of this powerful technology has been limited in part by the relatively high capital costs of an efficient ozone to water, gas-liquid, mass transfer system. Existing ozone injection devices must overcome the inherently low m ...

Lean burn spark engines are a promising technique to further reduce both NOx and hydrocarbon/carbon monoxide (HC/CO) engine emissions. Higher lean burn levels improve HC/CO oxidation while simultaneously reducing NOx formation. The NOx reduction is due to cooler flame temperatures. While the lean burn limit (beyond which combustion is poor) restricts further emission reductions, the use of oxyg ...

A number of industrial processes generate wastewater with mercury contamination. Existing cleanup processes have difficulties in achieving low mercury discharge limits, especially in the presence of competing metal ions already below their discharge limits. Commercial ion exchange media are not selective for mercury, so other metal ions compete with mercury for binding sites. Consequently, excess ...

This project addresses the development of diode-laser-based continuous-emissionsmonitors (CEMs) to meet the emissions monitoring requirements imposed on a widerange of industries by Federal and state clean air regulations. The overridingobjective is the development of new, highly reliably instrumentation that hassubstantially lower long term operating and maintenance costs than existinginstrument ...
