孝德文化相关材料（Related materials of filial piety culture） The direct water purifier includes: pure water machine and ultrafiltration membrane machine.

The tap of the straight drinking machine can be drinkable when opened, and is convenient and quick. 1. pure water machine The principle and disadvantages of pure water machine: ultra filtration machine is micron level filtration, and pure water machine is nano filtration. Because the membrane pore size is very dense, so the need to add water to the pump pressure through the filter membrane. Out of the water, there is 2/3 as wastewater (concentrated brine) flow to the toilet, 1/3 is pure water (desalted water) as drinking. Therefore, while removing bacteria and other impurities, all trace elements are also removed. At the same time, it is acidic water.

Common sense: microns and nanometers are only units of measurement and measurement. 1 meters =1000 mm, =1000 * 1000 microns, =1000 * 1000 * 1000 nm Chinese products use ultrafiltration membrane as filtration equipment. The following is the use of direct filter machine cost analysis, so that the salesman to filter the use and life, price understanding. Take the table type direct drinking machine and the warm straight drink machine two models as an example, because the two machines configuration and the use are co
