The reverse osmosis system is a process that allows only pure water to pass through the membrane, separating the dirty part by releasing water into a semiconductor membrane through pressure.

The reverse osmosis method has been used since 1970 to purify water, to obtain fresh water from seawater, and to obtain pure water that is of particular importance to medicine and industry. Currently, it is the most popular technology used for pre-treatment of plastic and bottled water.

The reverse osmosis is one of the most promising and widely used methods of water treatment. The reverse osmosis filters effectively remove particles from 0.001 to 0.0001 microns in water. Hard salts, sulfates, nitrates, sodium ions, small molecules and dyes fall into this range. The membranes used for the opposite osmosis are very sensitive to contamination. Initial filtration is performed in front of the system to clean larger particles for more efficient and longer-term operation of the reverse osmosis filters.

Synthetic semiconductor membranes are widely used in water treatment systems. The membrane retains large-scale molecular contaminants, but also contains small molecules, soluble gases such as oxygen and carbon dioxide. passes.

The main feature of the filters using reverse osmosis technology is almost complete sterilization of water. Water molecules (0.3 nm in size) pass through filters, but most chemical contaminants and biological substances do not penetrate mainly microorganisms and viruses (sizes between 20 and 500 nm). For example, a filter may capture and retain cholera bacteria or hepatitis viruses.
According to the World Health Organization (WHO), the effects of microbial contamination of drinking water on health are so important that their filtration is always important.
