Q:What filters can filter salt water into water?What filter can filter salt water into pure water?
If not, can filter the impurities, then the evaporation, evaporation of water vapor over the hood, get salt away, and then get a lot of water cooling.
Q:Will the water after the installation of the water filter be not boiled by the superior?
Whatever the machine filters, boil it before drinking it, because there is contamination in the pipe through the pipe, unless it's a very clean pipe that has just been replaced
Q:Can the filtered water of the tap water filter be used directly without water storage?
It depends on which grade your water filter is.The advanced water filters contain instructions for direct drinking
Q:Family moved a new home, the district used is deep well water, want to press a purifier. Just clean up the drinking water. The price will be around 3000. Advertising is not necessary, I was confused ~ ~ ~!
The general pure water machine uses the RO membrane reverse osmosis method. Can effectively remove 95% of impurities in water.
Q:Can the water outside the filter be taken straight away?
Can not.... Do you really believe in how big a bottle of water can be?
Q:We need to do living water filtration and purification in our project living quarters. What kind of equipment do you need? How much, approximately?
Pure water, its purification degree is high, generally 0.1nm (1 nanometer, namely 10-10 meters), almost filtered out all impurities in water, and the water taste pure. Some purification equipment in the manufacture of pure water, and then add a level of science, to increase mineral content, and make water weak base (pH value is slightly greater than 7), known as weak alkaline mineral water, the actual still belongs to this category of pure water. It should be explained that the minerals that people need in the water want to be retained, while the heavy metals and chemical pollution that are harmful to people want to be filtered out, but in water purificationIt is difficult to solve the problem when both are retained at the same time (such as purified water), or simultaneously filtered (e.g. pure water), hoping to retain one and remove it. From the point of view of purification, the use of pure water, which can filter almost all kinds of pollution, may be better. The loss of minerals can be supplemented by other methods, such as drinking milk (120 times the amount of calcium in the water of the same amount of water).
Q:What is the working principle of the safety filter in the purified water equipment?
The filtered liquid is pressed in by the inlet of the filter and is filtered out into the clarified liquid through the filter core from the outside through the filter layer, and then discharged through the outlet. Impurities are trapped in the deep and surface of the filter, so as to achieve the purpose of liquid filtration, but the filter should not be used too long, because the filter core is easy to breed bacteria.
Q:What is drinking now is ground water, which is pumped directly from the ground by the well and then consumed. Previously, the water quality is very good, because the cattle live, it may be cattle feces and urine contaminated groundwater, resulting in slightly yellow color of water, odor after the entrance. In the milk tea, there is a marked change, milk tea color will be more black.I hope that experts and enthusiastic friends on water treatment will give you some advice.
5, improvement points1) box material improvements: better sealing2) improvement on the fan: replace two power larger AC fans or turbofan3) filter: buy better filters4) control improvements: use raspberry pie + relay as control, use crontab control switch5) Internet air purifier: Raspberry pie, Internet access, remote control
Q:The difference between a water vapor filter and an oil gas filter
Oil and gas filter can be adopted by the general principle of adsorption or suspension isolation principle design, adsorption principle, mainly by lipophilic materials, oil and gas by lipophilic materials will make the oil and gas in the oil adsorption on its surface, which will filter out oil and gas. Suspension separation principle can make the oil and gas pass through the liquid (such as water) which does not dissolve the oil, at this point, the oil and gas will form small oil droplets suspended in the upper layer of the liquid which does not dissolve oil, thus the oil and gas will be filtered out.As for the structure of water vapor filter and oil and gas filter on a variety of differences, mainly in accordance with the principle of its use is different, there is a difference, talking about the length of space is very long.
Q:Drink tap water well, or purifier treated water okay?
Of course, the water treated with a water purifier is good. It filters bacteria, heavy metals and so on
