Reverse osmosis is the process of water moving from low to high concentration through a semi-permeable membrane, mainly used for wastewater treatment. By applying pressure on the salt side, water is forced through the membrane, leaving dissolved salts behind. It effectively removes over 99% of dissolved salts and bacteria, making it useful for desalination and industrial applications.

2. What is reverse osmosis?
Reverse osmosis is the passage of
water from a region of low concentration
to a region of high concentration through
a semi-permeable membrane. It is used
to treat wastewater.

3. How reverse osmosis works
Reverse Osmosis works by applying a
pressure on the salt side of the RO and
force the water across the semi-
permeable membrane which leaves
almost all of the dissolved salts behind
in the reject stream. The amount of
pressure required depends on the salt
concentration of the feed water.

5. Principles of Reverse Osmosis
Reverse osmosis used in desalination
operates on this principle – to draw fresh
water through a semi-permeable
membrane from high TDS(Total
Dissolved Salts) solutions such as
seawater, brackish water, industrial
effluent and other sources. It is capable
of removing 99%+ of dissolved salts,
bacteria, etc.
