Wastewater treatment requirements – a moving target

A short video on construction of a plant

Building an Extended Aeration Plant

Not to mention… ever-changing industrial processing requirements and plant discharge limits. These are all factors that can affect influent characteristics, plant loadings, operation, performance, compliance and running costs.

In these days of increasing industry legislation and scrutiny, the need to plan, evaluate, audit and optimize plant performance throughout the year means process simulation software is now becoming an essential tool for wastewater treatment plants, large and small.

Make SASSPro V2 your first choice! Set up your plant in minutes and analyze process
changes in seconds – using an industry proven process simulator with an unmatched
range of productivity tools and diagnostics.

SASSPro V2 requires no lengthy user training courses and is a fraction the cost of
top-end process simulators. And, if you need help setting up your process
simulations – expert assistance is only an email away.

Key Features

  • With over 120 activated sludge process outputs, built-in operational calculations,
    standard plant metrics (loadings, efficiencies, removals, PE etc), and automatic unit
    conversions, SASSPro V2 is unmatched as a powerful wastewater process calculator.
  • Live reactor status reports facilitate study of biological processes
    within individual reactor zones of the activated sludge process, and provide instant
    feedback for optimization of process parameters such as flows, reactor volumes, and
    RBCOD, nitrate, phosphorus, oxygen, nitrification and denitrification levels.
  • Built-in Wizards for fast setup; Using the QuickStart
    Wizard, you simply select a process configuration and type in the influent
    characteristics to create a default simulation. The QuickDesign Wizard lets you
    create a plant from basic design criteria in 5 easy steps. The QuickCal Wizard
    assesses your plant settings and prioritizes inputs requiring actual plant data
    for optimum results.
  • A single keypress provides instant Sensitivity Plots for any process input.
    Process outputs can also be optimized for key operating variables e.g. effluent
    concentrations can be plotted versus reactor recycle flows and influent concentrations
    to investigate optimal values and sensitivities.
  • MultiSim mode lets you store and plot monthly simulations of your plant operation.
    Each simulation over a 12 month period independently records seasonal loadings and
    plant configuration changes, allowing annual comparisons against any process output.
  • Primary Settler, VFA enhancement and Carbon Dosing options add flexibility for
    plant augmentation and contingency handling studies.
  • Built-in Clarifier simulator (with both Vesilind and Takacs models)
    can be used as a standalone module or in-line with the activated sludge process outputs
    to study secondary settler optimization, operational characteristics, wasting and
    recycle flows.
  • Diagnostic Test module provides flexibility for operational, design and
    regulatory tests on plant processes and outputs.
  • The SASSPro design emphasis is on ease of use, productivity and simplicity for
    routine PC users – without need for the extensive training or mathematical knowledge
    often required by users of training and modeling software. Included also, are snapshot
    saves, instant hint bar, glossary, context sensitive help, a user logbook for record
    keeping, and optional on-line troubleshooting and data analysis.
  • SASSPro is based on latest wastewater research and design recommendations for
    Biological Nutrient Removal (BNR) and Enhanced Biological Phosphorus Removal (EBPR)
    activated sludge processes.

Rapid Plant Assessments

Activated sludge systems capable of carbon oxidation, nitrification, denitrification
and phosphorus removal are complex. The implications of efficient nitrogen and
enhanced biological phosphorus removal (EBPR) on plant design and operation are
significant.

SASSPro V2 provides a highly productive environment for investigating activated
sludge processes ranging from single stage aerobic systems, to complex processes
incorporating nitrogen and enhanced phosphorus removal.

Designing a Denitrification/Phosphorus Removal Plant

Designing a Denitrification/Phosphorus Removal plant

Evaluating impacts on plant processes due to changing conditions can be a
costly nightmare. Take the hassle out of understanding your plant behavior.Learn how the plant processes work. Solve problems in advance. Analyze past
incidences. Plan for future changes. SASSPro V2′s user-friendly design will save
you hours of time and quite possibly… tons of money.

Training Material included

Includes over 150 pages of training material on activated sludge technology – covering
principles of operation, process characteristics, stoichiometry of biological reactions,
nitrification, denitrification, phosphorus removal, secondary settler operation and
process equations.
