Overview of reverse osmosis:
Reverse osmosis technology is a modern high technology recently developed in China. Reverse osmosis refers to the separation of water from the solution by applying a pressure higher than the osmotic pressure on the solution after the water penetrates into a special translucent membrane. Since this process is opposite to the direction of natural penetration, it is called reverse osmosis. According to the osmotic pressure of various materials, a pressure higher than the osmotic pressure can be used for reverse osmosis process to achieve the purpose of separation, extraction, purification and concentration of a certain solution. It does not require heating, and there is no phase change process; therefore, it saves more energy than traditional processes.
1. High-quality drinking water in residential areas meets the demand for high-quality drinking water in high-end residential areas. Support drinking pure water 24 hours a day.
2. The pure water production plant can be equipped with an automatic filling machine to form an automatic barreled water production line.

Each link uses a different filter:
Quartz sand filter
Quartz sand filter (multimedia filter) is widely used in drinking water treatment to remove different types of particles, such as suspended solids (turbidity), colloidal compounds, etc., to ensure that the TDS of the filtered water is less than 5. Reduce the burden of the back-end fine filter.
Activated carbon filter
Activated carbon filter is a key device, usually used to remove organic matter and heavy metal elements, suspended solids, residual chlorine, etc. It can effectively reduce the COD content and improve the taste of water. The system is a pressure filter. In the filter, an activated carbon bed of quartz and coconut shell is used. The activated carbon is equipped with an exhaust valve at the highest point and a discharge port at the lowest point. The internal systems and components of each storage tank are made of frp materials.
Safety filter (micron filter)
Safety filters are most commonly used in water treatment. The whole system uses a set of stainless steel filters. There are 3 sheets of polypropylene in each 5μ filter element, which can filter most of the particles in the water, thereby reducing the load of the reverse osmosis membrane. This filtration process benefits the filter cartridge and extends its service life in the system. The device contains a filter assembly and a stainless steel support layer. The support layer is made of 304 stainless steel, which has the advantages of compact structure, beautiful appearance, large flux, and good filtering accuracy. The device is equipped with exhaust valve, bottom exhaust valve and side exhaust valve.
Primary and secondary reverse osmosis system (RO)
The reverse osmosis system is a key part of the water treatment system and is widely used to produce pure water and drinking water. When the RO membrane is located on one side of the selective membrane, many types of macromolecules and ions can be removed from the solution by applying pressure to the solution. The result is that solutes such as iron, viruses, bacteria, and solids remain on the pressurized side of the membrane, while pure solvent can pass through the other side.
