WTTP 1830 - Mechanical Systems II
Description
This course is a continuation of Mechanical Systems I course and covers in more detail the selection, operating principles, adjustment and maintenance of mechanical equipment used in water and wastewater treatment processes and facilities. The course is arranged in three general sections, starting with moving process equipment, major process equipment and finally secondary process equipment systems.
Program
This is a core course requirement for all students enrolled in the Certificate in Water & Wastewater Utilities.
Objectives
Upon Completion of this course the students will gain understanding in:
- Moving Water - the main process of water flow (i.e. water or wastewater) through a treatment facility and the equipment used to control the flow.
- Major Process Equipment -the equipment used to achieve the initial mixing of chemicals with the process water stream and the equipment used to flocculate coagulants within the process water stream.
- Secondary Process Equipment
