How do you filter water when you need it but don t have clean water?

When we need to use clean water but don't have clean water, there are many ways to filter the water. There are several main ways to boil water in a kettle, filter water through a filter, precipitate water with chemicals, and precipitate water naturally. <>

First of all, boiling water is relatively easy to understand. If the water does not reach 100 degrees, there are actually a lot of microorganisms in the water. If you drink such unclean water, it will cause serious harm to the human body.

A previous survey report showed that if a person drinks unboiled water for a long time, the number of parasites and trace elements in his body are abnormal. After a long time, it will cause great harm to the human body. So, if we don't have clean water when we need it, the best thing to do is to boil it.

High temperature can kill most of the bacteria in the water, and can effectively remove microorganisms in the water. Therefore, boiling water in a kettle is one of the effective ways to make the water clean. <>

The second is that the water can be filtered using a filter。Nowadays, there are many businesses that manufacture and sell water purifiers, and a big reason is because most of the water we use is not very clean and hygienic. Although there are water companies that carry out unified processing and treatment, the water problem is still relatively serious.

At this time, it is necessary to prepare a filter, and after the first processing of the water company, it will be filtered by itself. After two or three times of processing, the water will reach a relatively clean standard. <>

The last way is precipitation, which is more suitable for scenes in the wild。If you need water in the field and there is no clean water nearby, the most convenient and fast way is to sediment. There are two types of precipitation, one is natural precipitation and the other is precipitation with the addition of chemicals (e.g. alum).

Both of these methods are more suitable for survival in the wild, and natural precipitation is more recommended.

Choose a physical water purifier. It is best to choose a gravity water purification bag. Gravity water purification bags generally have two filter bags connected by a hose.

One of the filter bags contains a filter. After filling this bag with water, hang it up and the filtered water will flow into another clean filter bag. This method is quick and convenient, and it also saves you the hassle of carrying around a large number of disposable filters.

The filtration of this water depends on the belongings you have with you, and of course the easiest way is to stir the water and let it settle.

Then choose distillation, such water is generally clean and pollution-free, and many use this method.

Find a container to hold water, put kapok branches and leaves in the container, cactus, pay attention to the need to mash, then stir evenly and settle for 30 minutes, take the upper layer of water to use.

Filtering water requires brainstorming, stirring the water vigorously, and then waiting for the water to stand still, and the dirt will settle.

When you're in danger and don't have clean water, you have to filter it yourself. Otherwise, you may get sick as a result, making the situation more complicated.

Put the kapok branches and leaves, cactus in the container, pay attention to the need to mash, then stir evenly and precipitate for 30 minutes, and take the upper layer of water to use.

After natural water is purified by precipitation, filtration, adsorption, etc., the water obtained contains water, soluble calcium and magnesium compounds and other substances, which belong to the mixture A mixture is a substance formed by mixing two or more substances.

Compared to tap water, the Ministry of Health.

There are higher requirements for direct drinking water. In the standard of tap water, it is mainly required that there are no pathogenic pathogens in the water, no carcinogenic, teratogenic and mutagenic substances, and good sensory properties. However, the standards for direct drinking water announced by the Ministry of Health of China are relatively stricter, which is mainly manifested in the fact that it is more beneficial to human health.

On the basis of tap water, it is required that the water first contains minerals and trace elements that are beneficial to the human body.

Secondly, for oxygen in the water, as well as carbon dioxide.

solubility as well as the pH of water.

There are also certain requirements. In addition, internally, it requires water to be small molecules with five to six molecular clusters. Finally, water is also required to have physiological activities including osmotic power, solubility power, metabolic power, etc.

The water purifier is divided into mineral water dispenser and purified water direct drinking machine. The water purifier should be used with a water storage tank to use electricity and generate wastewater. If the machine at home does not have a water tank, does not use electricity, and does not discharge wastewater, it is not a water purifier. The water produced is mineral water.

1. Mineral direct drinking machine: It can filter out agriculture, fertilizers, metal residues, and harmful substances in the water, and retain the trace elements and minerals needed by the human body. No electricity, no waste water, easy to use.

2. Water purifier: only water molecules are retained, and all other substances are filtered out. Electricity is used, waste water is generated, there are water storage tanks. It is not suitable for babies to drink, and the growth of babies is inseparable from trace elements and minerals.

The commonly used methods of filters are: ultraviolet sterilization, ozone sterilization, activated carbon adsorption, polymer material filtration, magnetization and other methods, these methods are physical methods, which will not destroy the trace elements in the water, and the simple filtration will not remove the minerals in the water. If the filter has an ion exchange layer, it will remove some of the minerals (heavy metal ions) from the water.

Generally, only RO reverse osmosis water purifiers will filter out minerals, and other water purifiers will not, but even if the minerals are filtered, drinking this water has no effect on people.

Pure water lacks minerals and trace elementsSome people think that drinking pure water has no nutrients and no trace elements, which is not conducive to human health. Actually, this kind.

Filtered water is not necessarily pure water.

Filtration is a common method of water purification. It removes suspended solids, colors, odors, impurities, etc. in the water through screening, adsorption, reverse osmosis, etc., which can reduce the number of harmful substances and microorganisms in the water. However, whether the filtered water quality is pure or not depends on the specific filtration method and the degree of pollution of the water source.

First of all, there are many filtration methods, and different filtration methods have different purification effects on water quality. For example, some low-grade filtration devices can only remove large particulate matter in the water, but cannot remove microorganisms and chemicals, and this filtered water is not considered pure water. The high-grade filtration device uses advanced technologies such as reverse osmosis, which can remove most of the harmful substances and microorganisms in the water, and the filtered water is relatively pure.

Secondly, the degree of pollution of the water source is also an important factor affecting the purity of the filtered water. If the water source itself has serious problems with stage tremor pollution, such as excessive heavy metals and harmful bacteria, filtration alone may not be able to completely remove these substances, and the filtered water is still at risk. Therefore, even if high-grade filtration equipment is used, it is necessary to choose a high-quality water source to ensure the quality of the filtered water.

To sum up, filtered water is not necessarily pure water. If high-grade filtration devices are used and water pollution is properly managed, the filtered water may be pure; Conversely, if the filtration device is not in place or the water source is heavily polluted, the filtered water may not be pure. Therefore, when choosing a filtration device or using filtered water, it is necessary to comprehensively consider many factors such as water source, performance of the device and filtration effect to ensure the safety and health of drinking water.

Filter the water through a filter.

Water dispenser? Water dispensers do not filter water for tiny particles unless the water is boiled by heating. Some suspended solids remaining on the filter.

The small impurities in the filtered air, and some oxidized or changed substances produced over time, may cause the filtered water to be unclean.

If it is industrial water, then it is even more troublesome, when filtering circulating water, the general filter can not filter slightly smaller impurities, and can not play the role of sterilization, anti-corrosion and descaling. If the equipment has been blistered for a long time, there will be rust, and there is no way to clean it.

On the one hand, it may be that the filter element has not been replaced, so that the harmful substances are blocked on the hole, and the water that comes out is not clean.

On the other hand, it is also related to the filtering method of the filter.

Ultrafiltration cannot filter out micro-pollution of heavy metals, residual chlorine, and organic matter.

Although RO can achieve clean water, the wastewater is large, and the water that comes out is pure water, and the water quality is acidic, so it is not suitable for long-term drinking.

Nanofiltration is in between, which can not only go out of micro-pollution, but also retain minerals, and the water that comes out can be drunk directly.

Is the filter dirty? There are just a few cartridges.

To make dirty water clean, you can filter it by physical methods, you can make a homemade filter through activated charcoal, paper towels and other tools, or buy a filter. Clean water can also be obtained by heat distillation.

If there are some high-tech machines, filter them with high-tech machines.

If not, strain it with gauze a few times first. It will be a lot cleaner, sprinkle some lime.

When I need water but don't have clean water, I leave it for a while, because it allows the dirt in the water to settle at the bottom.
