Intro to Drinking Water Treatment | DelftX on edX | Course About Video

SPEAKER 1: The Netherlands,
sometimes better known as Holland, where the
Dutch live, work and study. Holland, a country with
many rivers and lakes, which obviously means a lot of water. Water for transport, water for sailing. The Dutch are very familiar with water. Naturally, water is also
needed worldwide for drinking. Preferably, healthy water. This is the famous Delft
University of Technology. It’s sanitary engineering
department presents you with an online course
on water treatment. SPEAKER 2: Water treatment. It is essential. PROFESSOR LUUK RIETVELD: The
Dutch drink water from the tap. They don’t feel the need for using
bottled water or point-of-use filters. Moreover, the water
is soft, has no color, or turbidity and, without
chlorine, has a pleasant taste. The drinking water is obtained by
treated groundwater or service water. One of the most important aspects
of the multi-barrier system is the dune infiltration where
service water is naturally treated with this clean dune sand. No chemical disinfectants
are used in the Netherlands. And this is only possible because of
the multi-barrier system producing biological stable
water to avoid regrowth of bacteria in the distribution network. By the way, I’m Luuk Rietveld. I’m professor of urban
water cycle technology and I will teach the drinking water
treatment part of this course. We answer questions such as– SPEAKER 3: Is groundwater obstruction
responsible for the deterioration of national parks? SPEAKER 4: How is the quality of our
drinking water being safeguarded? SPEAKER 5: What is the
function of a water tower? SPEAKER 6: Why do we flush our toilets
with clear and costly drinking water? SPEAKER 3: Is it safe
to drink rainwater? SPEAKER 7: Can you purify
water with your own filters? PROFESSOR LUUK RIETVELD:
Now DelftX offers you an excellent course based
on TU Delft campus course.
