Why filtration process is better than sedimentation and decantation process?

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.

∙ 13y agoThe answer is found when you consider the size of the particles. Solids have large particles, while liquids do not. When you filter a solid and liquid through a porous membrane, the liquid particles can pass through the membrane, leaving only the solid behind.

This is, of course, only the case if the filter is able to filter out the precipitate. If the ppt is too small, for example, then filtration is ineffective. Also if you just want to get MOST of the liquid out but is not essential to get all, then decanting is an OK way of doing things.

What is meant by the terms decantation and filtration?
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.
Which method is better for separating mixture evaporation or filtration?
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.
Can you separate cooking oil from water by filtration?
No, it is hardly possible to filtrate one of the two fluids in an heterogeneous mixture. This can better be done by centifuging.
What is the process in which large hydrocarbons are converted into smaller hydrocarbons which provide better fuel?
Process is called cracking.
Why tear the edge of a filter paper?
Tearing a corner of the filter paper allows it to fit inside of the funnel better during filtration. If done properly, there will be no bubbles between the filter paper and the funnel creating a vacuum effect that greatly speeds up the filtration process.

Why Filtration is a better method than simple sedimentation and decantation?
Filtration can remove solid particles as small as 1 micron. Simply decanting, or allowing solids to settle - will not remove the smallest particles.
What is filtration and why better than sedimention?
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.

What does a diffuser on a bong do?
A diffuser allows smoke to be broken up into smaller streams allowing better filtration and cooling.
What type of water filtration should I upgrade to?
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.
What are the issues that you are facing in the world that would make water filtration a viable option for many people?
it can be way much better
Why hot lime soda process you better than cold lime soda process?
because☻ In Hot Lime Soda process reaction proceeds faster due 2 temp.☻ It requires no coagulants because sludge is formed rapidly☻ Viscosity of softened water is lower, so filtration becomes much easier☻ Its produces water of hardness with 15-30 ppm
Why sieve is used to separate tea leaves from tea?
It depends on how you do it. If you use a filter - it's filtration; if you use a sieve, it's sieving.
How is centrifugation better than filtration?
Filtration is a general term most often characterized by size separation (trap larger objects while letting smaller objects through, by chemical bonding/breaking, or electrostatic attraction. Centrifugation works with specific gravities or densities of materials to separate them. Which is better depends on what materials are being separated, and at what volumes.
Who designed the first water filtration system?
The ancient Greeks were credited with the first water filtration system that was put in to effect in 2000 BC. While it used a rudimentary system of sand, gravel and charcoal it was effective in cleaning water and making it taste better. The more modern filtration system that are used today were not implemented until the early 1700's.
Can you separate cooking oil from water by filtration?
No, it is hardly possible to filtrate one of the two fluids in an heterogeneous mixture. This can better be done by centifuging.
