01
What is purification of
food and beverage
What is purification of food and beverage
● Purification of food and beverage
is the process of making it safer
for human consumption.
●
Removes toxins and biological
materials that can impact the
safety of the food and beverage.
02
Why is it important
Why is it important
● Food is needed by humans for
survival.Without clean food,humans will
not be able to survive
● Purification of food and beverage is
important because it can help eliminate
pathogens(an organism that causes
diseases), bacteria, algae,etc. This makes it
safer for consumption.
● This ensures the survival,growth and
development of humans
03 :
What is the separation
technique used in
purification of Food
and Beverage that we
want to implement ?
IT IS
REVERSE
OSMOSIS !
4.a
What is it
What is it
●
Reverse Osmosis is a separation
technique that separates water
from molecules and ions using a
semi permeable membrane and
external pressure that is greater
than the osmostic presurre
4.b
How does Reverse
Osmosis impact
the food and
beverage industry
How does Reverse Osmosis impact the food
and beverage industry
●
Through reverse osmosis,water that is used to
make food and beverages is purified,resulting in
cleaner and safer food and beverages
● Moreover, higher food concentration in food
products is achieved through the extraction of
water from these products using reverse
osmosis
● Moreover,reverse osmosis is energy efficient
separation technique which reduces productions
cost for the food and beverage industry allowing
for more products to be produced within a lower
budget
4.c
How reverse osmosis
works
How reverse osmosis
works
●
In this source, reverse osmosis is being used to
separate the water from the salt water.
●
To do this,salt water is placed on one side of the
U-tube and a semi permeable membrane in the
middle of the U-tube.
●
Pressure,greater than the osmotic
pressure(minimum pressure needed to stop the
solvent from passing through the semi permeable
membrane) is exerted on the salt water.
●
The water molecules passes through the
semi-permeable membrane
●
Pure water is collected as on the other side while
the salt and other impurities are collected at the
other side of the U-tube

How reverse osmosis is
used in the food and
beverage industry
How reverse osmosis is used in the food
and beverage industry
● First before using it in the Food and Beverage Industry, the
water must be purified.
● To do this water is forced to go through a semi peremeable
membrane ,which is wrapped around the core tube in the
water filtration system.
● The water then flows in a spiral direction and through
pressure exerted on the water by the membrane, it passes
through the wrapped membrane’s walls.
● Each time it passes through the membrane walls, it gets
purified of dissolved and suspended chemical
particles,minerals,ions,nutrients,bacteria etc
● Eventually,The purified water is collected in the core tube
and then is transported through tubes to be used for other
purposes
How reverse osmosis is used in the food
and beverage industry
● We are now going to talk about how reverse
osmosis is used in food production
● Pressure,greater than the osmotic pressure of a
food mixture. is applied to the mixture of food and
water.
● The water molecules passes through the
semi-permeable membrane
●
Pure water and the purer food mixture are
seperated
● This is done so as to dehydrate the the mixture
and increase the food concentration
● Examples of these food that are dehydrated are
dried fruits,milk,chips and many more
4.e
Environmental,economic and
social effects of reverse
osmosis
Environmental effects of reverse osmosis
●
Due to scalling and fouling, reverse osmosis membranes are
regularly cleaned with chemicals that may be toxic to
receiving waters
●
The discharge from this has to be pre and post treated with
chemicals, respectively.
●
As a result, The discharge is mainly brine with concentration
that is twice of that of seawater. and includes traces of various
harmful chemicals used in cleaning and is released into the
water bodies
●
It then reaches the bottom layers of receiving waters and
pollutes the environment for marine creatures leading to loss of
biodiversity
●
Though not documented, it is possible that small traces of toxic
substances used in the cleaning of reverse osmosis membranes
may be harmful to marine life and ecosystem.
Economic effects of reverse osmosis
● Reverse osmosis actually benefits the
economy
● Reverse Osmosis is energy efficient and
hence costs less.
● This way,the price of water decreases which
results in companies being able to produce
more food products
● This benefits the economy in return as there
are more goods in the market for trade
Social effects of reverse osmosis
● Water that has undergone reverse osmosis is demineralized,
aggressively seeking to absorb new metals and minerals to
absorb
● Hence,when water that has undergone reverse osmosis is
used in making food products,the water absorbs nutrients in
the food and from the people who eat it
● Hence when people eat the food,they do not get enough
nutrients which affects growth and development which is
especially important for children.
● Water ,undergone reverse osmosis, in the food readily absorbs
materials and gets contaminated easily.When made with food
products,the water gets contaminated by chemicals,pathogens
etc and contaminates the food products with toxins

How do we implement reverse
osmosis sustainably
●
How do we implement reverse osmosis
sustainably
Environmentally
○
The discharge in factories is inevitable.So to make the discharge less
harmful for the environment, we can diffuse the brine better through
perforating (making small holes) the discharge pipe running on the water
bodies and by adding nozzle diffusers that have rubber check valves.
○
●
We can also dilute the brine when reaching maximum brine discharge
limit.This will make it less harmful to oceans as the concentration of toxic
brine released into the surroundings is reduced.
Social
○
The pipes and tanks that channel and use water that has undergone
reverse osmosis should be cleaned every day
○
This way,water that has undergone reverse osmosis does not get
contaminated and food products made are made healthier,benefitting the
people’s health
