 COURSE DESCRIPTION

Water supply and its treatment system are attached with the life cycle of every human being. To identify the problems associated with the treatment of the water and its supply it is essential to have the knowledge of this course. Students learn Effect of population dynamics on water demand, Physicochemical Principles applied in water treatment, Unit operations, principles and processes for pre-treatment and treatment of raw water, Principles, functions and design of different treatment units and processes. Upon completion, students should be able to design and construct the water treatment plant for the single unit, residential area or for society along with knowledge of distribution of water and requirement of building plumbing. 

COURSE OBJECTIVES

  1. Understand the basic principles and concepts of unit operations and processes involved in water treatment.
  2. Understand the disinfection process in water treatment.
  3. Understand the details of water supply systems.
  4. To teach students pipe network design for the supply of water to the group of tenements. 

COURSE OUTCOMES

On completion of this course, the students will be able to

  1. Know the type of unit operations and processes involved in water treatment plants.
  2. Understand unit operations and processes required for satisfactory treatment of water.
  3. Know the design of unit operation or process appropriate to the situation by applying physical, chemical, biological and engineering principles.
  4. Design water treatment units in a cost effective and sustainable way and to evaluate its performance to meet the desired health and environment related goals.
  5. Design pipe network for water supply for residential and individual buildings.
