Undergraduate Course: Water Engineering, Transport and Treatment 3 (CIVE09035)
|School||School of Engineering
||College||College of Science and Engineering
|Credit level (Normal year taken)||SCQF Level 9 (Year 3 Undergraduate)
||Availability||Available to all students
|Summary||This course is a natural extension of the hydrological component of Water Resources 2 and the hydraulic component Fluid Mechanics 2. The course covers: the practical considerations arising from the demand for water from community development; water transport in pipe systems and open-channels; modern treatment processes for water, wastewater and sludge; effluent disposal; river pollution. It provides Civil Engineers with the necessary tools to design a Water or Wastewater Treatment Plant, essential knowledge for the 4th Year Design Project on Potable Water.This course is intended to:¿provide insight into the fundamental problems of water transport, and water and wastewater treatment engineering;¿develop understanding of steady flow in pipe systems, pipe networks,pumping mains, and open channels;¿outline the methods for the production of potable water,wastewater treatment for safe disposal, and the fundamental design of treatment works.
