The most effective manner of obtaining support is via email to support@envirosim.com. Please send your questions and attach the BioWin file to the email. In this way we can be viewing the exact system while working on the issue. EnviroSim software support is focused on ensuring that our customers are getting the most productive use of our modeling software suite. Our support team is here to help with product use, product functionality and product configuration questions.

Consulting vs. Support

The difference between support and consulting :

Questions related to the software such as ‘How do I export my data?’, ‘What model best simulates a trickling filter?’, or ‘How do I customize my Album?’ would be considered support questions.

Questions related to process engineering such as ‘How do I achieve an effluent nitrate concentration of less than 5 mg/l?’ would be better answered by our consulting services team.

Building a Model

Building a BioWin Model

Building a calibrated BioWin model involves configuration of the model and calibration against historical plant data. Typical data required are:

Physical plant dimensions
Plant operating data such as recycle rates and DO concentrations
Influent flow and loading data
Influent wastewater characteristics

A good overview of a structured modeling approach is provided in “Region-wide Wastewater Treatment Plant Modeling Enhances Facility Management and Planning’, Bye et al“. A comprehensive explanation can be found in the WERF manual ‘Methods for Wastewater Characterization in Activated Sludge Modeling’.

BioWin closes after entering activation code

Unable to create backup file

I am trying to open a BioWin configuration and the following message appears: Error – Unable to create backup file

BioWin creates a backup of the BioWin configuration when it is opened. The backup file is located in the same directory as where the BioWin configuration is located. This error will occur if BioWin does not have write access to that directory. If write access cannot be granted to that directory the BioWin configuration should be moved to a directory with read/write privileges.

The File|Open menu in BioWin automatically opens in the Data directory which by default is installed inside Program Files. Often write access is disabled in this directory. To change the Data directory location:

In Windows Explorer locate the Data directory.

In 32-bit versions of Windows the default directory is C:Program FilesEnviroSimBioWin X.YData.

In 64-bit versions of Windows the default directory is C:Program Files (x86)EnviroSimBioWin X.YData.

Where X.Y is the version of BioWin that is installed.

Copy the Data directory to a location that has read/write privileges.
Start BioWin.
Go to the Tools|Customize menu and click the File locations tab.
Select Data files and click the Modify location … button.
Find and select the Data directory that was copied in Step 1 and click OK.
Click the Close button.
Restart BioWin.

This file was generated using a newer version of BioWin

I am trying to open a BioWin configuration and the following message appears: “This file was generated using a newer version of BioWin. This version of BioWin can only open files generated in version X.Y, or an older version.”

BioWin must be updated in order to open the BioWin configuration. Click here to update to the latest version of BioWin.

Note: BioWin configuration files that are saved in a later version of BioWin may not be able to be opened in an earlier version. Backups are recommended.

A COM error occurred

When I start BW Controller the following message appears: “A COM error occurred”

BW Controller uses registry entries that require administrative privileges to create. These registry entries are normally created by the BioWin installer. There are two solutions if you encounter this problem:

Download and install the latest version of BioWin
Run BioWin once with administrative privileges.
- Locate the shortcut to start BioWin.
- Right-click the shortcut and click Run as administrator.
- Wait for BioWin to start and close it.

Note: It is only necessary to do this procedure once. Administrative privileges are not necessary once the registry entries have been installed.

Click the steady state or dynamic solver and nothing happens.

When clicking the steady state or dynamic solver, the mouse looks like it is thinking and then nothing happens. Plus, the solver pop-up window is not visible.

Periodically Microsoft releases updates that cause this issue when using an external monitor. The way to resolve this issue is to:

Unplug your laptop from the external monitor.
Start BioWin, and try to run a simulation. The steady state / dynamic “start” control dialogue should appear as normal. Run the steady state, solve, say OK.
Plug back into the external monitor. Try running another simulation, and things should proceed as normal.
