The technical core of the direct drinking water machine is the reverse osmosis membrane. Its working principle is to exert a certain pressure on the water so that the water molecules and ionic mineral elements pass through a layer of reverse osmosis membrane, and most of the inorganic salts dissolved in the water are dissolved. 0001--0. 001μm, equivalent to one-millionth of a hair. The smallest viruses are also above 0.2 microns, so they cannot pass through the reverse osmosis membrane.

    According to the use situation, it is divided into manual type (also economical type) and automatic type. The difference is only in the backwash of the direct drinking water machine. The economical direct drinking water machine uses a manual backwash valve. The characteristics of the direct drinking machine: there is a booster pump, need a power supply, there is a water storage tank, and generally.

    It is a five-stage filtration, the first stage is a filter element, the second and third stages are activated carbon, the fourth stage is RO reverse osmosis membrane for aerospace technology (this is the core), and the fifth stage is refined activated carbon, which is mainly used to improve The taste can also be placed on the fifth stage of the medical stone filter to become a mineral drinking water dispenser.

    It can not only remove impurities, rust, sediment, colloids, bacteria, viruses, but also radioactive particles, organic substances, fluorescent substances, and pesticides that are harmful to the human body. When you boil water, there is no water alkali, and at the same time ensure the health of your family's drinking water

    The direct drinking water machine will mainly produce waste water in the process of water production. The pore size of the RO reverse osmosis membrane of the direct drinking water machine is very small. If it is small, the water must be driven by pressure, and the impurities that cannot pass through the RO membrane will be poked out. It also produces waste water, but this water waste water can be reused, such as flushing toilets and mops.
