Digital Images Of Water And Wastewater Processes For Engineering Education

The purpose of this project is to develop a web site to provide environmental engineering faculty with digital images of water and wastewater processes in order to enhance the classroom learning experience. In addition, a CD-ROM of the same material will also be available at the conclusion of the project. We will provide quality digital images of water and wastewater processes, including both still and video images. Most images are available for download in three resolutions. High resolution images (300 dpi, 5” × 7”) are recommended for printing; midrange resolution images (72 dpi, 800 × 600 pixels) are recommended for use with a computer and LCD projector; and compressed, low resolution images (72 dpi, 480 × 360 pixels) are recommended for Internet usage and for viewing on a computer monitor. Videos are provided in compressed, low-resolution quality (320 × 240 pixels) that is suitable for Internet delivery and in high-resolution quality (720 × 480 pixels) that is recommended for computerized projection. In the past, overhead transparencies and slide shows were used to depict engineering schematics and on-site photographs of engineering projects. However, schematics and photographs copied to overhead transparencies are generally of poor quality, and the use of slides requires the instructor to darken the room, inhibiting note-taking. Furthermore, the classroom material is often in the possession of the instructor, limiting or precluding student review outside of the classroom. The availability of web based material, whether from the instructor’s web site, or other sources, opens an entirely new venue to assist students in becoming familiar with the various engineering processes.
