Advantages and Disadvantages of Reverse Osmosis

Advantages and Disadvantages of Reverse Osmosis

Following are Reverse osmosis advantage and disadvantages of reverse Osmosis.

Advantages of reverse Osmosis:

- Reverse osmosis softens the water.

-Reverse osmosis is the process removes the dissolved substance from the water and maintain the TDS of the water.

-Reverse osmosis also filters remove many bacteria and pathogens from water.

Bacteria are effectively filtered out from your water.

- No, any chemical treatment is involved in Reverse osmosis. Only filtration and pressure technology is used in Reverse osmosis.

- It requires minimum space for installation.

Disadvantages of reverse Osmosis:

- Wastage of water is happened due to the Reverse osmosis.

- The cost of the system is high    

- Frequently replacement of the membrane used in Reverse osmosis process is required.

- Maintenance needs to be required.

Hypertonic Solution: Definition

Definition:

-Hypertonic solution is defined as the solution which has higher solute concentration compared to another solution.

-With respect to the osmotic pressure, Hypertonic solution is defined as the have higher osmotic pressure.

-Hypertonic solution is the comparison of the concentration of solute with respect to the other solution.

Hypotonic Solution

Definition:

-Hypotonic solution is defined as solution which has lower solute concentration compared to another solution.

-With respect to the osmotic pressure, Hypotonic solution is defined as the have low osmotic pressure.

-Hypotonic solution is the comparison of the concentration of solute with respect to the other solution.

-The solvent moves into the hypotonic solution. 

Diagram of Hypotonic Solution movement:

Hypotonic Solution movement

Here the B side is the hypotonic (The concentration of the solute is lower) Solution which has low concentration of solute than the Side A.So the solvent molecule move towards the hypotonic solution (B) till the concentration of both sides is equal.

Isotonic Definition

Definition:

-Isotonic solution is defined as the solution which separated by the semi permeable membrane and has same concentration of solute at both side solutions.

-In other words, isotonic solution is defined as the solution that has the same osmolarity.

-Hence the concentration of the solution is equal at the both side of the semi permeable membrane there is no movement of the solvent.

Example:

Isotonic saline solution is given to the patient. The saline solution 0.9% solution chloride. It is the example of the isotonic solution with blood.

Tonicity Definition

Tonicity Definition:

Definition:

-Tonicity is also defined in terms of the osmotic pressure. Tonicity defined as the measure of the osmotic pressure gradient between two solutions.

-In simple language, tonicity is the relative concentration of the solution as compared to another solution which separated by the semi permeable membrane.

Based on the tonicity of the solution it is classified.

There are three types of the solution based on the tonicity

Hypertonic solution

Isotonic solution

Hypotonic solution

Difference between Osmosis and Reverse Osmosis

Difference between Osmosis and Reverse Osmosis

Osmosis and the reverse osmosis are the two phenomenon in which occurs due to the movement of the solvent. The main difference between Osmosis and the reverse osmosis is direction of the movement of the solvent and the pressure applied.

Here, following are the difference between the Osmosis and reverse osmosis.

	Osmosis	Reverse Osmosis
Definition	Osmosis is defined as the movement of a solvent through a semi permeable membrane to lower concentration to higher concentration.	Reverse osmosis is defined as the movement of the solvent through the semi permeable membrane from higher concentration to lower concentration with pressure
movement	The solvent transfer from lower concentration to higher concentration	The solvent transfer from higher concentration to the lower concentration.
Pressure	Pressure is not required	Pressure is required then only reverse osmosis is possible. Applied pressure on higher concentration.
Example	Movement of water in root	Purification of the water.
Process	It naturally occurs.	It is simulated process
Energy	Energy is not required for the process	Energy is required for the process.

Reverse osmosis definition

        Reverse osmosis definition:

        Definition:

Reverse Osmosis is defined as the movement of solvent in the opposite direction from the osmosis; when pressure is applied.
Pressure is most important factor in reverse osmosis process.

Diagram of Reverse Osmosis:

Reverse Osmosis

-Here is a diagram, the red molecules are the molecule of the solvent while the blue is the solute molecule. And the dotted line is the semipermeable membrane. Pressure is applied to the side where the concentration of the solute is high.

-Due to the applied pressure, thee red solvent molecule passes through the semipermeable membrane toward the other side where the concentration of solute (Blue color molecule) is low. This phenomenon is known as Reverse Osmosis.

Osmotic pressure Definition

Osmotic pressure Definition:

Osmotic pressure defined as the Maximum pressure developed in osmotic process.

Osmotic pressure is the pressure required to prevent the movement of the water across the semipermeable membrane

Potential osmotic pressure Definition :

Potential osmotic pressure defined as the maximum osmotic pressure that develops in a solution when separated from its pure solvent by a semipermeable membrane.

Difference between Blood and Plasma

Blood and plasma are the two different elements. Plasma is the component of the blood. Plasma is approximately % of the blood complement. There are so many differences between blood and Plasma.

Following are the difference between Blood and Plasma

	Blood	Plasma
Definition	Blood is the fluid in our body which transport nutrient and the oxygen to the different cell of the body.	Plasma is the yellow colour fluid; left after removal of blood cells which constitutes 55% of blood part.
Component	Blood is composed of plasma, blood cells(red blood, White blood, and platelets)	Plasma composed of the water, protein, nutrient, electrolyte, and gases.
Colour	Red Colour fluid	Light yellow colour liquid
Donation	Blood donation is very common	Plasma donation is less common.
Treatment	Blood is directly collected from the vein.	For Plasma collection special machine and treatment are required.

Definition of crystal Habit

Definition of crystal Habit:

-A crystal habit is defined as the description of the outer appearance of a crystal whereas the internal structure is the molecular arrangement within the solid.

-Any crystal is characterized by its internal structure and habit.

-Crystal habit can also be modified by adding impurities or ‘poisons’; for example, sulphonic acid dyes alter the crystal habit of ammonium, sodium and potassium nitrates.              

-It can be quantitatively expressed in terms of aspect ratio (AR), defined as the ratio of length to width and values of AR approaching 1 (spherical or cube shape) are considered to be pharmaceutically good. It is preferable to keep the AR values below 5 so as to avoid problems with flow. AR in polar solvents was as high as 9.4 in comparisons with 5-6 in non-polar solvents.
