Frequently Asked Questions


AMDTreat is a tool to assist users in the process of estimating the long-term cost of abatement of pollutional mine drainage discharges.

AMDTreat provides a detailed framework for calculating real-world site-specific treatment cost estimates.

AMDTreat users can model costs both forward (In advance of construction.) and reverse. (Determining the cost of a previously constructed system.)

AMDTreat is a powerful what-if modeling tool to help in determining the most cost effective long-term treatment type for a given discharge.

AMDTreat is a flexible tool for estimating costs where the user has full control over how and what elements are considered.

AMDTreat is not a design tool, it is a cost modeling tool.

AMDTreat requires a Windows 2000 or XP operating system; a Pentium computer; and a minimum screen resolution of 1024 by 768.

Currently, there is no Cut and Paste function on any of the menus; however, you can cut and paste by blocking the desired text or number, then using Ctrl+x or Ctrl+c, for cut or copy, and Ctrl+ v for paste.

This connotes a critical error and it must be corrected before proceeding.

This error can occur in any AMDTreat routine that sizes impoundments. It is the result of a combination of low flows, narrow surface widths and too much pond depth. These conditions can cause AMDTreat to model a non-viable structure. (e.g., a pond with a negative bottom width) When this error occurs, the portions of the screens that contain pond depth values turn red.

This is done to alert the user that the pond being modeled is not viable to construct. In most circumstances, the error can be corrected by entering depth values for the structure within an acceptable range! Acceptable ranges are provided to the user in the detailed error message. However, when the error results from a pond with a negative bottom width the error cannot be corrected by changing depth values.

When this occurs, the user must change the sizing methodology for the pond to size the pond based on dimensions. It is one of the key assumptions of the software that all ponds are trapezoidal in shape.

To save a project, select the File menu from the upper left portion of the screen then select the Save As menu item (File->Save As).

You will be prompted for a project name, a company name (optional), a Site Name, a date and comments (optional). By default, AMDTreat v4.x saves your files into a folder (directory).

The default AMDTreat folder is My Documents/AMDTreat. Each saved project is stored in a separate folder within that folder.

To save updated information in an already saved project just hit the Save button (File->Save). To load a saved project just select the Open menu item from the File menu (File->Open).

You must uninstall previous versions of AMDTreat in order to upgrade to a new version. To uninstall AMDTreat, on most versions of MS Windows*, go to "Control Panel." Select "Add Remove Programs" then select AMDTreat from the list of installed programs and click on Uninstall or Remove.

* Windows 7 and Windows Vista: To uninstall previous versions of AMDTreat, go to "Control Panel." Select "Programs and Features" then select AMDTreat from the list of installed programs and click on Uninstall..
