In modern society, many families in order to improve the quality of life, drink safe and clean water, will generally choose to install a water filter in the home. Therefore, a water filter has become a necessary means and measure to protect the daily drinking water of modern people.
So, in the past, when the conditions of clean water were not developed, what efforts did people make to drink clean water? Come and have a look!
Europe: The great art of beer brewing
The eruption was a massive wave of cholera in Europe in the 19th century, the cause of cholera outbreak is a contaminated water supply, later, it inadvertently found that barley after fermentation, such as boiling treatment, not only can eliminate deadly bacteria such as E. coli in water, to safeguard the basic security of drinking water, the taste is very delicious, so beer formal onto the historical stage, began to gradually become the mainstream of the drinks.
Gulf states: simple distillation
Seawater is not directly drinkable, because its salinity is too high, beyond the human body should be ingested range, drink more seawater, the more thirsty, eventually lead to cell dehydration, and seawater contains many impurities, such as the naked eye can not identify microorganisms, parasites, and even cause poisoning and other symptoms.
Use a simple bowl or shell to scoop some seawater, drill wood fire after the bowl is heated, the bowl is attached to the inside of the cloth and other absorbent materials, evaporation after the cloth water wringing out, the repeated operation can obtain fresh water.
China: Tea culture with a long history
Speaking of Chinese tea culture, we must be familiar with it! But what else do you know about tea besides its mellow flavor? In the “Shennong Baicao Classic”, it is recorded that Shennong tasted Baicao and encountered 72 poisons in one day, and got tea and solved them. Tea polyphenols in tea have certain bactericidal, bacteriostasis, and detoxification effects. So in the past, when water quality was poor, drinking tea was safer and healthier than drinking raw water.
With the improvement of people’s awareness of water purification, water purification technology is also constantly developing. we have many ways to filter tap water now. For example, we can install a water filter in our refrigerator, there are many filter models we can choose from, like edr1rxd1 water filter ,edr2rxd1, and so on.
But do you know how the original water purifier was made?
Initially, people just use gauze, quartz sand filter, cannot eliminate the naked eye can’t identify the bacteria in water, then inadvertently activated carbon has been found to have effective adsorption ability, activated carbon filter began to pop it, through the constant improvement of the water purification technology, gradually evolved into the water purifier we use today.
Of course, after the installation of the water purifier, do not ignore the importance of daily maintenance, so as to continue to play the maximum role of the water purifier and prolong the life of the machine.
First of all, don’t place the water purifier in the region of the sun, at the same time should steer clear of the heat source, water purifiers in use after a period of time, also don’t forget to regularly to filter machine for cleaning, replacement, long work of filter, the impurity adsorption capacity will gradually be saturated, so please according to your usage to change it regularly.
