  Superheated Water and Steam Degreasing of Working Stocks, Parts, and Equipment in Machining, Manufacturing and Production Processes and Operations, Descrição: EPA Grant Number: R828246 Title: Superheated Water and Steam Degreasing of Working Stocks, Parts, and Equipment in Machining, Manufacturing and Production Processes and Operations Principal Investigator: Weber, Walter J. Institution: University of Michigan EPA Project Officer: Karn, Barbara Project Period: September 1, 2000 through August 31, 2003 Project Amount: $320,000 RFA: Technology for a Sustainable Environment (1999) Research Category: Technology for a Sustainable Environment This study will identify and develop an environmentally benign, innovative, efficient, low-cost technique for degreasing working stocks, parts and other metal surfaces using superheated water and steam. By utilizing the unique properties of pure superheated water for this purpose it is anticipated that the current use of conventional hazardous organic and alkaline solvents will be markedly reduced. The research will demonstrate that superheated water and/or steam (SHWS) will provide the same level of degreasing as conventional solvents. It is expected that the energy costs for heating water and steam will be more than balanced by the reduction of treatment and disposal costs below those associated with traditional organic and alkaline solvent systems. For difficult degreasing situations that require solvent modifiers such as surfactants and chelating agents, superheating the water will allow minimization of these additives, reducing direct costs and wastewater problems. . , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (4) / Especialização: (0) / Mestrado acadêmico: (0) / Mestrado profissional: (0) / Doutorado: (2) . , Integrantes: Roger de Almeida Pinto - Integrante / Hildegarde Selig - Integrante / Walter J Weber Jr - Coordenador / Carl Lenker - Integrante / Angela D Lueking - Integrante / Michelle Butler - Integrante., Financiador(es): U.S. Environmental Protection Agency - Cooperação.

  Development and Verification of A Molecular Modeling Approach for Predicting the Sequestration and Bioavailability/Biotoxicity Reduction of Organic Contaminants by Soils and Sediments, Descrição: EPA Grant Number: R825540C001 Center: HSRC (1989) - Great Lakes/Mid-Atlantic HSRC Center Director: Hunter, Ray Title: Development and Verification of A Molecular Modeling Approach for Predicting the Sequestration and Bioavailability/Biotoxicity Reduction of Organic Contaminants by Soils and Sediments Principal Investigators: Weber, Walter J. , Huang, Weilin Institution: University of Michigan , Drexel University EPA Project Officer: Manty, Dale RFA: Hazardous Substance Research Centers - HSRC (1989) Research Category: Hazardous Substance Research Centers The general objective and ultimate goal of the proposed research is to develop a set of quantitative structure-activity relationships (QSARs) based on a combination of experimental measurements and molecular modeling/simulation for predicting sorption distribution coefficients, isotherm nonlinearity, and sorption-desorption hysteresis for any cmbination of organic contaminants and soils/sediments and set of site-specific conditions. The QSARs so developed will have the property of being readily calibrated to specific situations by a minimal set of laboratory and/or field measurements Rationale: Accurate prediction of fate and transport and successful clean up of contaminated sites under various specific conditions require accurate assessment and quantification of the binding and sequestration properties of the soil/sediment and organic contaminants involved. Sorption, desorption, and sequestration are processes that are traditionally quantified experimentally. While providing direct and reliable information, the associated measurements often involve: i) complicated procedures; ii) sophisticated laboratory facilities and technical training; iii) multiple levels of quantification; iv) extended periods of time; and, v) large costs. These requirements may be prohibitive for routine assessments of large numbers of organic pollutants and widely varied soils and sediments. , Situação: Em andamento; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (4) / Especialização: (0) / Mestrado acadêmico: (2) / Mestrado profissional: (0) / Doutorado: (3) . , Integrantes: Roger de Almeida Pinto - Integrante / Michael Keinath - Integrante / Hildegarde Selig - Integrante / Walter J Weber Jr - Coordenador / Qingguo Huang - Integrante / MinSun Kim - Integrante / Weilin Huang - Integrante., Financiador(es): U.S. Environmental Protection Agency - Cooperação.

  A Comprehensive Investigation of the Effects of Organic Geochemistry on the Sorption-Desorption, Sequestration, and Bioavailability of Mixed Organic Contaminants in Subsurface Systems, Descrição: EPA Grant Number: R825962 Title: A Comprehensive Investigation of the Effects of Organic Geochemistry on the Sorption-Desorption, Sequestration, and Bioavailability of Mixed Organic Contaminants in Subsurface Systems Investigators: Weber, Walter J. Institution: University of Michigan EPA Project Officer: Lasat, Mitch Project Period: January 1, 1998 through December 31, 2000 Project Amount: $440,748 Research Category: Hazardous Substance/Hazardous Waste , Bioremediation The fundamental objective of this study was to establish a rigorous scientific foundation for risk-based decisions regarding acceptable alternative endpoints for soil and sediment remediation. The study evaluated the complex role of soil and sediment organic geochemistry on the environmental mobility and bioavailability of hydrophobic organic contaminants (HOCs) in systems with multiple organic solutes. Particular emphasis was placed on examination and documentation of the multiple mechanisms that slow desorption and contaminant sequestration. To this end, systematic studies were conducted in multi-contaminant systems to address the effect of soil organic matter on: (1) HOC sorption-desorption hysteresis, desorption rates, and sequestration; (2) the subcritical water extractability of sorbed HOCs; (3) the bioavailability of sorbed HOCs to bacteria and to earthworms; and (4) the effect of cumulative solute residence time on the sorbent or so-called "aging" on each of the foregoing. . , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (3) / Especialização: (0) / Mestrado acadêmico: (1) / Mestrado profissional: (0) / Doutorado: (2) . , Integrantes: Roger de Almeida Pinto - Integrante / Michael Keinath - Integrante / Hildegarde Selig - Integrante / Walter J Weber Jr - Coordenador / Marty D Johnson - Integrante / Angela D Lueking - Integrante / MinSun Kim - Integrante / Deborah Ross - Integrante., Financiador(es): University of Michigan - Ann Arbor - Outra / U.S. Environmental Protection Agency - Cooperação.
