The method of filtering drinking water turns out to be like this

Although people's daily drinking water is already very clean after being processed by the water plant, the residual chlorine used for purification and the bacteria in the secondary water supply tank are harmful substances that we have to guard against. So how do we filter drinking water so that we can drink it safely? Now let’s learn how to filter drinking water!

Some people think that ordinary tap water is treated and disinfected, so how can there be any trace of water pollution? In fact, this idea is wrong! The real situation is often not like this, although the tap water we use is filtered, cleaned and processed by the water plant and basically meets the drinking water standards. However, some pollutants cannot be removed. Where does all this pollution go? These pollutants that cannot be removed are a safety hazard to our drinking water.

On the one hand, these pollutants enter the body through drinking water and directly damage health. Heavy metals such as lead, chromium and mercury are internationally recognized as highly toxic pollutants. Polycyclic aromatic hydrocarbons and various pesticides can affect your health. In addition, substances such as nitrogen and phosphorus can cause eutrophication of water, while cyanobacteria and algae can release hepatotoxins and neurotoxins, polluting water quality.

In addition, irrigation water will pollute the soil, causing contamination of agricultural products such as grain and vegetables. After pollutants such as chromium and mercury enter the water body, they will accumulate in aquatic organisms such as fish, all of which will indirectly harm people's health.

Therefore, before drinking water flows into the body, the best way is to perform secondary treatment on the drinking water entering the home. At this time, boiling tap water and installing a water purifier are necessary. Household water purifiers can filter out visible and invisible impurities such as residual chlorine and heavy metal ions in the water. It is an essential household device to ensure the safety of drinking water.

The experiment of boiling drinking water for three minutes has proved that when tap water is boiled for three minutes, the toxic substances in it can be degraded to a minimum. This kind of water is the best water for people to drink. Using boiling water to cook can prevent most of the calcium carbonate, magnesium carbonate, mercury, cadmium, lead, arsenic and other harmful substances in the water from entering the human body, reducing the incidence of stone disease and chronic poisoning, and preventing the chlorine contained in tap water from destroying the vitamins in food when cooking.

Use vinegar or beer to remove scale. Add some vinegar or beer into the kettle and shake it to dissolve the scale attached to the wall of the kettle. Pour naturally fermented and soured thick rice soup or noodle soup into the kettle to remove the scale attached to it. Put tea leaves in the kettle and soak them in boiling water to remove scale.

Use cotton balls or loofah pulp to remove scale. Wrap a small ball of absorbent cotton in gauze, or use a piece of loofah pulp with the seeds removed, and put it in the kettle when boiling water. The scale will adhere to it.
