Introduction 1:
A once great man, wrote about the R.O a small but
meaningful poem:
Clear water you want to have/
Yet, your tap produces brown
Get into the science, yes my
friend/ Where all comes down, osmosis
Put a membrane in between/ Two
different solutions of water
And, Watch them move from
the sparser to the other in, /Elevating the surface,
there you have osmosis.
Now, if you want the other
way around, apply some pressure dear/ To the dirty part of the equation,
And watch the brown water
become clear/ Through the same membrane that rejects the filthiness, it’s my
impression.
Where it all comes down,
reverse osmosis.
Introduction 2:
Dear descendents of Thales and Descartes, I would like
to involve you in describing a procedure full of equations and numbers: Reverse
Osmosis. With a production rate or fresh water that ranges from 30% to 90%, R.O
is one of the best potable water purification techniques so far. Actually, it
is an inversion of the osmosis equation π = iMRT, where π= osmotic pressure, i=
the Van’t Hoff Factor, M is molarity: good old moles per liter, R is the gas
constant and we will be using the same value as in the gas laws unit: 0.08206 L
atm/mol K, while T is the temperature. In other words, reverse osmosis is using
mechanical induced pressure π’>π in order to reverse the osmosis through a semi
permeable membrane and purify the water. (retrieved from http://www.chemteam.info/Solutions/Osmosis.html)
Introduction 3:
Dear all, please let’s watch all together the
following introduction video about reverse osmosis. Please focus on the
procedure and give me your feedback if the media serves its cause, by means of
image quality, colors, visual effects, audio and motion. I will later do the
same about the Reverse Osmosis.
Introduction 4:
Ok people; let’s talk about water treatment and reverse osmosis. What, you
don’t know what it is? Simple. Give me an R, and give me an O. I
want three people to form a human wall. Now, I want two teams, the blue one and
the black one. All members should try to push through the human wall. Now, the
wall’s job is to allow for the blue team to pass, but not the black one. So, you may start [….after the activity, you speak again…] Well, this is how it works, dirty
water is being pushed through a
membrane, while the membrane leaves only clear to water pass, and does not
allow for the pollutants to pass through. The movement of the water can only go
in one direction.
Introduction 5:
Ok ladies and gentlemen, let’s rock out to reverse
osmosis, and then we can discuss which were the influences of the artist and
how he can manage to hydrate himself with good quality water. Click to Play:
Dear all,
Let’s
all sit on the round table and discuss about purifying water, as it resembles
to a behavioral process. Please accommodate yourself and try to think that
Reverse Osmosis is like having a filter in ones personality and character that
allows you to accept positive thinking but repels the negative one. All of the
pressure built up from family, friends, peers, colleagues etc can become
productive, if you realize that this filter can keep only the things that you
need and block all the other to your subconscious drain.

My fellow travelers, let us contemplate and talk about
one of the five elements of the circle of life: Water. Let us stay in a nice
lotus position and acknowledge that our soul is dirty from the everyday
struggle. Let us breathe deeply, like putting pressure into our bad self to be
exhaled and keeping only the good thoughts and memories within us. So as, the
reverse osmosis technique can clear the water, as a wall that allows water
residues to be taken away, and grants us with pure water, needed for a balanced
body in order for the soul to follow.
Introduction 8
Welcome
to our session. As you possibly already know, osmosis is a natural procedure
which occurs if we separate two solutions of different concentration by a
biodegradable organic membrane of cellulose; an ingredient that can be found everywhere
on the earth’s flora. This way the clearer solution “runs” to the more
saturated one, thus pressure is produced by this movement called osmotic
pressure. Yet, in many occasions, mainly in gardening and grocery production
(like hydroponics) we need specific quality of water for our plants. So, man
reversed the natural procedure of osmosis, by putting reverse pressure so the
effluent travels backwards, while the membrane doesn’t allow pollutants to pass
through
