Decantation and filtration both are used to separate parts of a mixture from one another. Decantation is the process of separating a liquid from a solid by gently pouring the liquid from the solid so as not to disturb the solid. Filtration is the process of separating a solid from a liquid by means of a porous substance (filter) which allows only the liquid to pass through.
In AP Chemistry
The larger and heavier solid particles settle down leaving the clear liquid above it. ... At the same time, during decantation, there is a chance of the particles mixing back in the liquid. The filtration technique can be used to overcome this as well. Thus, filtration is better than sedimentation and decantation.
To separate kerosene and water from sedimentation, you can use a process called decantation. Allow the mixture to settle so that the sedimentation settles at the bottom. Carefully pour off the kerosene layer, leaving the water and sediment behind. You may need to use a separating funnel for better precision in separating the layers.
Examining urine sediment immediately after decantation allows for better visualization of cellular elements like red and white blood cells, bacteria, and crystals, as they may settle quickly. Delaying examination can lead to sediment drying out or cells deteriorating, potentially affecting the accuracy of the analysis.
If you have a solid precipitate /liquid mixture filtration is the better method of recovering the solid as any contaminant in the liquid can potentially be washed out. Evaporating the liquid to remove it would just deposit whatever residues there were onto the precipitate.
No, it is hardly possible to filtrate one of the two fluids in an heterogeneous mixture. This can better be done by centifuging.
Filtration is more effective than simple sedimentation and decantation because it can remove smaller particles that may not settle out on their own. It also allows for the separation of solids from liquids more efficiently, leading to a clearer final product. Additionally, filtration can be faster and more controlled compared to relying solely on sedimentation and decantation processes.

Filtration is an effective method because it removes most of the dirt from a liquid whereas in sedimentation some semi soluble dirt is still left in the liquid and is not removed.
Suction filtration is typically faster and more efficient than gravity filtration because it uses a vacuum to pull the liquid through the filter paper or membrane, resulting in quicker filtration. Additionally, suction filtration is often more effective at removing smaller particles due to the enhanced force applied to the filtration process.
When detergent is added to the filtrate, it disrupts the lipid membrane of the particles, leading to the release of entrapped material and allowing for better separation during the filtration process. This helps in improving the efficiency of filtration by reducing clogging and increasing the clarity of the filtrate.
The use of a porous disk in filtration helps to improve the efficiency of the process by allowing for better separation of solids from liquids. The disk acts as a barrier that traps larger particles while allowing smaller particles and liquids to pass through, resulting in a cleaner filtrate. This helps to achieve a more effective and precise separation of substances in a laboratory setting.
Rate of filtration can be increased by using fluted filter paper.rate of filtration is related to surface area of the filter medium.In case of fluted filter paper surface area is increased ,as by folding the paper in such a way,the larger area of filter paper can be confined in the same funnel.so rate of filtration increases.

A diffuser allows smoke to be broken up into smaller streams allowing better filtration and cooling.
A good water filtration system using activated carbon for home wells is provided by Siemens and Ultrapure. The larger the system the better based on family size and well size.
