Water and waste water treatment

Overview

Waste water part of syllabus is covered from the headworks till the final Disinfection and Disinfectant removal,their design is also considered in detail. Water treatment portion covers the nitty gritty of treatment and the relevant aspects post treatment like residual removal. This course will allow the student to clear basics and concepts for further in depth learning.INTENDED AUDIENCE :Civil Engineering and Environmental Engineering/science studentsPREREQUISITES : NoneINDUSTRIES SUPPORT :None
