This ppt is on reverse osmosis which is an important topic in engineering chemistry

1. REVERSE OSMOSIS

2. Reverse Osmosis
Osmosis is the process by which water pesses through a semi-permable membrane from a Less (low)
concentrated solution into more (high) concentrated solution.
Reverse osmosis (RO)is a water purification process that removes ions, unwanted molecules.
Reverse Osmosis is a process which uses a membrane under pressure to separate
relatively pure water.

4.  What is Reverse Osmosis
The process of movement of solvent through a semi-permable membrane from the
solution to the pure solvent by applying exess on the solution side is called semi
permable membrane.
Reverse Osmosis is a membrane treatment process primarily used to separate
dissolved solution from water . Reverse Osmosis is most commonly known for its use
in drinking water purification, partially with regard to removing salt and other
effluent materials from water molecules.

6.  Benefits of Reverse Osmosis
1. This process can be used to effectively remove many types of dissolved and
suspended chemical particles like bacteria 🦠🦠from the water.
2. This technique has a wide application in treating liquid wastes or discharges.
3. It is used in purifying water to prevent deceases.
4. It helps in desalinating sea water.
5. It is beneficial in the medical field.

8.  Reverse Osmosis is capable of removing upto
99 % of dissolved salts ( ions),
particles,collides,organics, bacteria and
pyrojens from the feed water .An reverse
Osmosis membrane rejects contaminants
based on their size and charge
