With the emphasis on water pollution, many families choose to purchase a water purifier. But! Drink healthy water, have you ever thought that your water purifier would waste water?
In fact, every water purifier we purchase will have a “purified water rate†or “waste water rateâ€, and some wastewater will be discharged when it is used. Having said that, it is necessary to talk to you about the reason why the water purifier is watery.
In most of the water purifiers on the market, most of the water purifiers that can be said to waste water are RO reverse osmosis water purifiers.
RO reverse osmosis water purifier is a good quality water supply system. After the three pretreatments of PP meltblown filter, granular activated carbon adsorption filtration and compressed activated carbon filtration, the residual chlorine, suspended solids and rust in the water are removed. , colloids, etc., as well as most organic matter.
Then where does this impurity go? A part of the water is then filtered through the reverse osmosis membrane and the post-particle activated carbon to produce pure water for drinking. Most of the water passes through the first three passes and fails to pass the second-stage treatment, which becomes the concentrated water. These concentrated waters are called “waste water†by most people, that is, we are wasting water!
Is there a lot of water wasted by the water purifier? Isn’t the water and water saving really a combination of fish and bear's paw? I don't feel comfortable drinking water in the future!
In fact, it is not as serious as everyone thinks. In fact, the "waste water" is slightly higher than the tap water, and most other indicators, such as turbidity, color, residual chlorine, smell and taste, organic matter, suspended matter, colloid, COD ( Chemical oxygen demand), TOC (total organic carbon), SDI (contamination index), etc., are better than tap water.
In recent years, there have been a lot of news about water purifier wastewater. Although it is concluded that wastewater is not terrible, consumers don’t have to panic! But many manufacturers have seized the concern of consumers and launched “micro wastewater. Household reverse osmosis water purifier." However, “micro wastewater†is not “zero waste waterâ€.
The surface of household “micro-waste†seems to reduce the proportion of concentrated water (washing water) and pure water (drinking water) (at the cost of shortening the service life of RO membrane), but its key point is to regard high-quality washing water as “ "Waste water", it is discharged in vain, and its relationship with the so-called "conventional wastewater" is completely consistent in the nature of wasted water. Fifty steps to laugh a hundred steps!
So how much “waste water†can the water purifier waste?
Nowadays, the wastewater rate of most new water purifiers on the market has been controlled at around 1:1. Most of them are 1 cup of pure water, which discharges the “waste water†below the cup, and the amount of wastewater discharged by the better water purifier. The ratio will be less.
Some netizens have calculated an account. If they simply use pure water as the daily drinking water of the family, according to the amount of drinking water of a family of three, each person drinks 2L of water a day, 180L of pure water a month, according to 1:1. The wastewater rate, that is to say, the family will discharge about 180L of "waste water" in one month.
However, some netizens have calculated that we will abolish about 40L of water every day when we take a bath, and the family will have to pay 3,600L of water a month. Therefore, the "waste water" of the water purifier is much smaller than the water wasted by your bath. Don't worry too much about worrying about it, how to use it in peacetime!
What kind of water can you do? Let Xiaobian tell you to tell you how to use these "waste water": First, you can use washing water for kitchen utensils, then wash cloth and wipe the table, third, clean water for households, and finally You can also choose to use it to flush the toilet.
In general, it is everyone's responsibility to save water! Tell everyone that water purifiers will produce waste water just to remind everyone, the same water purifier produces waste water is not terrible.
