What is pure water machine
All organic pollutants and inorganic ions in the water are intercepted by RO membrane reverse osmosis with ultra-fine precision. There is a certain amount of waste water, and the outlet water is pure water for direct drinking
Why does pure water machine produce waste water in use
RO membrane filtration is the main reason for the generation of pure water machine wastewater. The membrane network of reverse osmosis membrane will block some small molecules larger than 0.01 nm, inorganic salts and other impurities outside, which will produce waste water. The proportion of pure wastewater of general household machine is 1:3. The meaning of the waste water discharged from the pure water machine is completely different from that in real life. It is too wasteful to drain the tap water after being filtered by ppcotton, prefilter and RO membrane. How to deal with it
1. Change the discharge ratio of pure water and waste water, increase the flow of pure water and reduce the flow of waste water. If the value of RO is less, the service life of pure water membrane will be reduced. If the waste water is reduced and the pure water is increased, the users must consider the health problems of the water dispenser.
2. In addition, it can be used to wash clothes in two buckets. But because the container is too small, the water will overflow quickly, and the container is too large and takes up space very inconveniently.
3. High level water tank: connect the concentrated shrinkage pipe of the pure water machine to the high-level water tank, so that the concentrated water generated during the pure water machine-made water is stored in the high-level water tank. The outlet of the high-level water tank can be connected with the flush toilet, the watering faucet, etc. (the high-level water tank is provided with an overflow port).
4. Pressure barrel: connect the concentrated shrinkage pipe of the pure water machine to the pressure barrel, so that the concentrated water generated during the pure water mechanism is stored in the pressure barrel, and the outlet of the pressure barrel is connected with a tap, which can be used as domestic water. High water tank and pressure barrel need to be invested in the early stage, but in the long run, it is more environmentally friendly and energy-saving than directly discharging the waste water.
