Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, specifically a two-stage reverse osmosis pure water equipment. Background Technology

[0002] Pure water is an inorganic compound. Although it is not rigid, its arrangement is much more regular than that of gaseous water molecules. In liquid water, water molecules do not exist as individual molecules. Therefore, the orientation and movement of water molecules are significantly influenced by other water molecules around them.

[0003] With the increasing needs of industry and daily life, the demand for pure water is growing. The preparation of pure water mainly relies on reverse osmosis technology. However, some reverse osmosis equipment can only perform single-stage reverse osmosis treatment. Although the treated water is relatively pure, it still contains certain impurities and salts, which cannot meet some high-standard water quality requirements. Therefore, it is of great significance to develop a two-stage reverse osmosis pure water equipment that can produce purer water. Utility Model Content
