The document discusses the history and benefits of water treatment plants. It explains that water treatment was first invented by ancient Greek and Sanskrit writings in 2000 BC where people would boil or filter water, though microorganisms and chemicals were still unknown. The first cloth bag filter was invented by Greek scientist Hippocrates in 500 BC. Later, Anton van Leeuwenhoek discovered microorganisms in water using microscopes. Today, water treatment plants purify water naturally without pollution while providing clean water for drinking, cooking, and bathing at schools like ATID without needing to purchase bottled water.

2. Hello, today we are going to show you how the
water treatment plant works, who were the ones
who invented, and what are the benefits of it.
Do you know that here, in the ATID school we
use a water filter to purify the water? Well that
benefits us in many ways, people who work at
school do not have to go to buy any carboy or
bottles of water we only use the water treatment
plant, it doesn`t pollute and it doesn`t affect us
neither the environment.

3. The water treatment was invented by the Ancient Greek and Sanskirt
writtings in the year 2000 B.C.
At this times people boiled the water, but they weren’t sure if it helped
purify the water, so they started to invent methods of filtration that
helped to reduce visible particles and turbidity in water.
they didn’t filtrate the microorganisms or chemical contaminants because
they didn’t knew that existed.
All they wanted was that the water smelled and tasted better.
There was a greek scientist named Hippocrates, who invented the first
cloth bag filter in 500 B.C. he also believed that if the water tasted and
smelled clean, it must be healthful for your body.
After the first microscope, Anton van Leeuwenhoek became the first
person who discover the microorganisms in water.
not clear or transparent because of stirred-up sediment or the like;
clouded; opaque; obscured

5. The water treatment plant helped the ancient society in many
ways there were no more deceases because of the water,
kids were no more sick and they could drink water of any
river as long as it was purified, the only thing they had to do
was filtrate it and the drink it, now they knew that the water
they were drinking was absolutely purified. They didn’t have
to last to much hours boiling water that wouldn’t purify.
Also today it helps, we don´t pollute the environment using
big machines, we just use a simple machine that helps purify
the water naturally. Also we don´t have to use to much water
bottles we can better use the drinking fountain.
We can even take a shower with purified water, just the same
water you drink!!
