2. 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.

3. 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.

mainly focuses on wastewater treatment
processes.

5. 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.

6. 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.

7. 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.

8. 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).

9. Unit Operation Models

10. 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.

11. 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

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

13. • 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.).

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

15. 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.).

16. 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

17. 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.

18. Physical and Environmental
Component Properties

19. • 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..

20. • 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.
