Generally speaking, basic home reverse osmosis systems cost between $200 and $600. These systems are usually suitable for small families and can meet daily drinking water needs. More powerful systems with higher processing capacity can cost up to $1,000 or even more.

Main types of water treatment machines: Reverse osmosis (RO) water treatment machine Ultraviolet (UV) disinfection water treatment machine Activated carbon water treatment machine Water softener Ultrafiltration (UF) water treatment machine Electrolysis water treatment machine

The higher the desalination rate, the better the purification effect of the system and the less dissolved solids in the pure water produced. Most high-quality reverse osmosis systems have a desalination rate of more than 90%, and some can even reach 99%.

Reverse osmosis membranes can be divided into many types according to the usage scenarios, membrane materials and processes. Different types of RO membranes differ in performance, durability and scope of application. Therefore, the membranes used in all RO equipment are not exactly the same.

There has always been a misunderstanding about whether reverse osmosis water is banned in Europe. In fact, there is no total ban on the use of reverse osmosis water in Europe.

The 2 cubic meters/hour reverse osmosis water treatment system is not suitable for ordinary families due to its high processing capacity and complex installation and maintenance requirements. For most households, a small reverse osmosis system can meet daily purified water needs。

seawater desalination is also one of the important application areas of RO technology, especially in areas with scarce water resources and coastal cities. Through the reverse osmosis system, salt and other impurities in seawater are effectively removed and converted into drinkable fresh water.

Differences in working principles ● Reverse osmosis relies on physical separation, separating water molecules under pressure through a semipermeable membrane. ● Distillation is based on phase change, separating impurities in water through heating and condensation processes.

The annual cost of maintaining a 2-ton reverse osmosis water treatment system is approximately between $3,700 and $6,900, depending on the quality of the equipment, water quality conditions, frequency of use, and maintenance management level.

The initial construction cost of the Sorek Desalination Plant was about $400 million, while the construction cost of the Carlsbad Desalination Plant was as high as $1 billion. As the world's largest desalination plant, the Ras Al Desalination Plant cost as much as $7.3 billion to build.
