Course summary
Without it we are dead! Water is essential, but
what processes must it go through to become fit
for human consumption? This free course,
Potable water treatment, will guide you through
the continuous cycling of water between land,
open water surfaces and the sea before moving
on to an overview of the water treatment and
supply process.
Learning outcomes
By completing this course, the learner should be
able to:
describe the operation and mechanisms of the
hydrological cycle
list and describe the major physical, chemical
and biological characteristics of clean fresh
water, and explain their effects on aquatic
organisms
explain the mode by which potable water is
produced through the processes of screening,
microstraining, aeration, coagulation and
flocculation, sedimentation, flotation, filtration
and disinfection
explain how the issues of nitrates, trace
organics, fluoridation and plumbo-solvency can
be dealt with in potable water supply
describe the main desalination processes used
to produce potable water from saline or
brackish sources.
