Modeling of Wastewater Treatment Processes

• SuperPro Designer can be used to model, evaluate, and optimize any type of Wastewater Treatment, Water Purification, and Air Pollution processes.

Modeling of Wastewater Treatment Processes

• Since SuperPro also handles a wide variety of chemical manufacturing processes, it is an ideal tool for evaluating Pollution Prevention and Control options and practicing Green Chemistry and Sustainable Development. EnviroPro Designer a subset of SuperPro, mainly focuses on wastewater treatment processes.

Modeling of Wastewater Treatment Processes

• EnviroPro/SuperPro Designer is a valuable tool for environmental consulting engineers, process and product designers, development engineers and scientists, treatment/disposal plant engineers and managers.

Modeling of Wastewater Treatment Processes

• It enables the user to efficiently develop, assess, and optimize environmentally beneficial technologies. It provides under a single umbrella modeling of chemical manufacturing and end-of-pipe treatment processes, project economic evaluation, and environmental impact assessment.

Modeling of Wastewater Treatment Processes

• EnviroPro Designer can be used to model, evaluate and optimize municipal as well as industrial wastewater treatment processes. It includes unit operation models for biological as well as physical treatment. The flowsheet below shows a simplified activated sludge process that treats industrial wastewater.

Modeling of Wastewater Treatment Processes

• EnviroPro also can be used to model and optimize nutrient (Nitrogen and Phosphorous) removal processes. For more info on nutrient removal, download the Evaluation version and have a look at the MUNWATER example (files b and c deal with nitrogen removal issues based on the Ludzack-Ettinger and Bardenpho processes).

Unit Operation Models

Unit Operation Models

• Unit Operation Models • EnviroPro Designer features intuitive dialog

windows for the initialization of unit operation models. In the following dialog window, the user initializes the kinetic data of Benzene biodegradation in an aeration basin. Notice the expression for the overall reaction rate and the blocks for specifying the substrate, other, and biomass terms.

Unit Operation Models

• The data for the reaction rate constants (Kmaxo, To, and Theta) as well as the half-saturation constant for the substrate term (Ks) are retrieved from the component database but the user also has the option to overwrite them locally

data for the reaction rate constants (Kmaxo, To, and Theta)

• EnviroPro Designer is equipped with rigorous biological reaction models. The models can handle any number and almost any type of reactions (e.g., biochemical oxidation, biomass decay, hydrolysis of particulate matter, chemical oxidation, photolysis, adsorption on particulate matter, etc.).

• biochemical oxidation, • biomass decay, • hydrolysis of particulate matter, • chemical oxidation, • photolysis, • adsorption on particulate matter

VOC emission calculations

• They can handle any number of biomass components (e.g., heterotrophic for biochemical oxidation and denitrification reactions, autotrophic for nitrification reactions, inactive biomass that decays, etc.).

VOC emission calculations

• They support VOC emission calculations based on mass transfer and equilibrium-limited models that are accepted by EPA. Finally, they consider sorption of heavy metals and other compounds on sludge and track their fate

Physical and Environmental Component Properties

• EnviroPro Designer features extensive databanks of chemical components and mixtures. A User databank is provided for storing information on components created by the user. EnviroPro is also compatible with a version of DIPPR, a commercial physical property databank that includes highly reliable data for around 1,750 compounds.

Physical and Environmental Component Properties

• The pure component databank includes thermodynamic (e.g., molecular weight, critical pressure and temperature, accentric factor, vapor pressure, density, specific heat, particle size, etc.) as well as environmental (e.g., diffusivities in water and air, biodegradation data, octanol to water distribution ratio, Henry’s law constant, component contribution to TOC, COD, BOD5, TSS, etc.) properties. The figure below shows some of the environmental properties for Benzene..

• The values of diffusivity (in water and air) are used for estimating emissions of this compounds from agitated (e.g., aeration basin) and quiescent (e.g., clarifier, thickener) tanks. The biodegradation parameters are used for estimating the extent of reaction of this compound in aeration basins (see second figure from top). The "Pollutant Categories" tab includes info used for regulatory reporting. More specifically, a compound can be classified as a volatile organic compound (VOC), Particulate, Acid Gas, ETG, CO, NOx, SO2, Base, etc. and this info is used in Emissions Reporting.
