Abstract: The application of the errors in variables method (EVM) to environmental engineering practice using, as an example, the determination of kinetic parameters from a laboratory biodegradability study is presented. Model ...

Abstract: For the estimation of moments from pulse-tracer experiments, prior workers have used trapezoidal rule integration as well as a generalized moment of inertia approach. In this technical note, these two methods are compared, ...

Abstract: Kinetic models for inactivation of microorganisms by chemical disinfectants have described the instantaneous rate of kill as a function of the instantaneous residual. Laboratory batch experiments were conducted exposing ...

Abstract: When a model is used to fit data containing dependent variables some of which are known only to be below some limit, special techniques must be employed. The present paper shows that ordinary regression, omitting those ...

Abstract: To ascertain whether bottom ash, or mixtures of fly ash and bottom ash from power generation could serve as acceptable final covers for landfills, field revegetation studies and indoor plant elemental bioavailability studies ...

Abstract: Aerosol dispersion in living spaces especially bioaerosols, due to accidents or deliberate acts, is of significant current interest. Computational fluid dynamics (CFD) provides an accurate and detailed platform to study ...

Abstract: Computational fluid dynamics (CFD) have been applied to predict the performance of chemical water treatment disinfection systems in recent decades. However, computation times remain sufficiently long and prevent their use ...

Abstract: Disinfection contactors are frequently characterized using tracer studies to determine macromixing patterns. For some applications, such as compliance with the surface water treatment rule, this information can be interpreted ...
