Can a Vortex Effectively Purify Water by Utilizing Gravity?

In summary, the conversation discusses using a vortex and the law of gravity to purify water. The suggested method involves building a funnel-like jar, clogging and unclogging the bottom, and relying on heavier particles to settle to the bottom. However, it is pointed out that this method may not be effective in removing dissolved substances. Another person suggests using a filter funnel and filter paper as a tried and tested method for purification. The definition of "purify" is also questioned, as removing only solid particles may not be sufficient for some uses.

TL;DR Summary
Purify water with vortex / law of gravity - good or bad?
What do you think of purifying water by using a vortex / law of gravity?

Here is what I am thinking:
1. Build a funnel-like jar, clog it on the bottom and fill the jar with water. Now wait for several hours.
2. Unclog the bottom, wait for a few seconds (depending on the size of the jar) and then clog it again.

It is my belief that heavier particles than water will fall to the bottom. And if you also unclog the bottom then a vortex will be created which will suck the impurities down even faster. What impurities will be left? The ones that weights less than water, which could either be boiled off or trapped in a filter. Again, it's only what I think, I am not an expert.

What do you think, is this a good purifying technique?

Try using a filter funnel and filter paper. More effective, existing technology, tried and tested for a few hundred years, much faster than what you are suggesting.

Basically, you are describing letting heavier solid particles, such as bits of mud, settle and hoping to wash them away. Normally when this is used, we decant the liquid off the top of the settled sediment. If we want to wait a few hours, rather than filter it.

Now if you are thinking of separating something that is dissolved in the water, say sodium chloride or ethanol or some soluble contaminant, you are on a loser. It will not work. It will not make purer water. Dissolved substances do not settle to the bottom of a liquid.

In short: define "purify". For some uses removing just solid particles will be OK, for other uses things that are left dissolved are much worse.
 

Related to Can a Vortex Effectively Purify Water by Utilizing Gravity?

1. How does vortex purification work?

Vortex purification involves using a spinning motion to separate impurities from water. The centrifugal force created by the spinning motion causes heavier particles to be pushed to the outer edges of the vortex, while cleaner water remains in the center.

2. What types of impurities can be removed through vortex purification?

Vortex purification can remove a variety of impurities from water, including sediment, bacteria, and some chemicals. However, it may not be effective in removing all types of contaminants, such as heavy metals or viruses.

3. Is vortex purification a reliable method for purifying water?

Vortex purification can be a reliable method for purifying water, but it is important to note that it may not be 100% effective in removing all impurities. It is best used in combination with other methods, such as filtration or chemical treatment, to ensure the cleanest water possible.

4. Are there any potential drawbacks to using vortex purification?

One potential drawback of vortex purification is that it may not be suitable for all types of water sources. For example, water with high levels of turbidity or suspended particles may not be effectively purified through vortexing. Additionally, the process can be time-consuming and may require specialized equipment.

5. Can vortex purification be used for large-scale water purification?

Vortex purification can be used for large-scale water purification, but it may not be the most practical or efficient method. It is more commonly used for smaller-scale purification, such as in household or camping situations. Other methods, such as reverse osmosis or UV treatment, may be more suitable for large-scale purification needs.
