              Welcome to SASSPro 'Demonstration version'

We trust you will be delighted with the quality of the product and the ease
of operation.


LIMITED TIME OFFER:
-------------------
With the introduction of our new Web site and Microsoft Network (msn) forum,
a SPECIAL OFFER is available on SASSPro packages ordered by April 30, 1996.

SASSPro is available at a special price of A$1500-00 (approx. US$1155 at the
current exchange rate US$0.77) i.e. 25% off the normal selling price of
A$2000-00.


INTRODUCTION:
-------------
SASSPro (Steady-state Activated Sludge Simulator, Professional Edition) is
a Windows 3.1 modelling program for wastewater research, plant design
evaluations, operations staff training and tertiary teaching purposes.

SASSPro provides extended modelling facilities across 8 primary plant
configurations, with selection from over 50 process parameters. Parameters
include mixed liquor, oxygen, nitrification, denitrification, phosphorus
and alkalinity calculations, sludge disposal costings and aeration power
requirements.

Comparative modelling is a key feature of the SASSPro program. Dual graphing
and parameter control facilities provide simultaneous comparisons between
multiple sets of system operating conditions (e.g. Peak vs Average, Summer
vs Winter, Best vs Worst case, etc.) with auto-increment, auto-scaling and
overlay graphing options for rapid sensitivity analyses.

Reactor volumes, recycle rates, oxygen levels and wastewater characteristics
are fully configurable, with dynamic re-calculation of Rsm (minimum sludge
age for nitrification) and optimum MLSS 'a' recycle flow rates.

SASSPro is an invaluable aid for process evaluation and sensitivity studies,
enabling the study of processes, design changes, contingencies and seasonal
variations more quickly, economically and thoroughly than is possible in a
real plant - as well as being an excellent medium for maintaining in-house
process familiarisation.

Used in industry and academic wastewater training courses as well as by
major municipal authorities and consultants in the wastewater industry,
SASSPro's design, ease of use and low cost have set new benchmarks in
wastewater modelling applications.

By increasing the base of experience and enhancing intuitive decision making,
SASSPro modelling facilities can play an essential role in helping municipal
wastewater treatment plants to comply with the increasing quality and
regulatory requirements demanded in today's environment.


SASSPro FEATURES:
-----------------
* Plots of over 50 process parameters, including Mixed Liquor, Oxygen,
  Nitrification, Denitrification, Phosphorus, Effluent and Alkalinity
  characteristics, Aeration power requirements and Sludge disposal costing.

* Simulates a wide range of existing and intermediate plant configurations,
  with choice of Concentration, mass and volume units for pilot to full size
  plants.

* Rapid set-up of reactor volumes, recycle rates, oxygen levels, inflow and
  wastewater characteristics, with Rsm and optimum 'a' recycle calculations.

* Dual graphing and parameter entry facilities provide simultaneous
  comparisons between different operating conditions (e.g. Summer vs Winter)
  for studies of sludge age, 'a' recycle, biomass temperature, influent
  characteristics and temperature coefficients.

* Graphing options include data cursors with autoscaling, auto-increment
  and overlay modes for rapid sensitivity analysis, and dual marker cursors
  for automatic difference calculations.

* Speed optimization and dynamic re-calculation facilities also enable
  use as a powerful wastewater process calculator.

* 'Help Bar' provides instant on-screen descriptions of all model parameters,
  minimizing the need for familiarity with modelling terminology.

* Capability to run multiple program instances for comparisons across a
  range of plant and load conditions.

* Detailed reports include graphs of selected parameters with all operating
  conditions listed.

* Data export in text (ASCII), Lotus and Excel compatible formats for
  transfer of calculation data into other software programs.

A basic version (SASS) is also available for introductory training.  Based
on a fully aerobic system, SASS provides mixed liquor, biomass, oxygen,
nitrification and effluent calculations with selectable primary wastewater
characteristics, temperature coefficients and kinetic constants.


GETTING STARTED:
----------------
Load Windows and run the SETUP program to install the SASSPro program on
the PC hard disk.  Note: SETUP can also be used to un-install the program.

Once installed, to load SASSPro select the SASSPro icon in the SASS
Analysis Group from the Windows Program Manager.

For details on program operation, refer to the context sensitive Help
facilities.  For an instant description of each model parameter, simply
place the mouse cursor over the parameter field - the description will
be displayed in the Hint Bar at the bottom of the screen.


DEMONSTRATION VERSION:
----------------------
All program features are fully operational in this demonstration version,
except printing and storage facilities.  An example report (SASSPRO.PRT)
and export file (SASSPRO.PRN) are included.  To print the report on a HP
LaserJet compatible printer use the following DOS command:

   COPY SASSPRO.PRT LPT1: /B

Note also that a random factor is applied to model outputs and a reminder
that it is a demonstration version will appear periodically on the screen
during operation.


DOCUMENTATION:
--------------
Purchased copies of this program include a comprehensive Operation Manual,
as well as an extensive reference manual (The Activated Sludge Resource
Book on Conventional and Advanced Processes).

The Resource Book provides a step by step training program on activated
sludge processes for wastewater treatment - including principles of
operation, review of conventional systems, process characteristics,
stoichiometry of biological reactions, process monitoring, kinetics of
substrate removal, nitrification and denitrification, nitrogen and
phosphorus removing processes and introduction to modelling techniques.
