RO water refers to water that has been treated with reverse osmosis (RO) technology. This technology is a water treatment method that uses semi permeable membrane filtration to remove impurities such as dissolved solids, bacteria, viruses, and organic matter from water, in order to obtain high-purity water. Below is an explanation of the basic principles of reverse osmosis technology and the characteristics of RO water:

The principle of reverse osmosis technology: Reverse osmosis is a process that uses high pressure to transfer water from a high concentration solution through a semi permeable membrane to a low concentration solution. A semi permeable membrane only allows water molecules to pass through, while rejecting the passage of most solute molecules and particles. In reverse osmosis equipment, water is forced through a semi permeable membrane with high pressure, allowing water molecules to pass through and leaving solutes on the other side. This process can effectively remove impurities from water and produce relatively high-purity water.

The characteristics of RO water:

High purity: The purity of RO water is usually above 90%, which can effectively remove harmful substances such as soluble solids, heavy metals, bacteria, viruses, etc. from the water. Widely used: Due to its relatively high purity and applicability, RO water has been widely used in drinking water, industrial production, electronic manufacturing, pharmaceuticals and other fields. Economical and practical: Compared to some high-purity water treatment methods, the production cost of RO technology is relatively low, making RO water more economical and practical in many scenarios. Adjustable: The RO system can be adjusted as needed to meet different water quality requirements. In daily life, we often hear the terms RO water and pure water, both of which are related to water quality, but what are the differences? RO water is the abbreviation for reverse osmosis water, while pure water refers to water that has undergone a series of treatment processes to remove impurities. Below, we will discuss in detail the differences between RO water and pure water in terms of production, usage, and water quality.

1. Different production processes

The production of RO water is mainly achieved through reverse osmosis technology. This technology utilizes a semi permeable membrane to block harmful substances such as dissolved solids, bacteria, and viruses from the water on one side of the membrane, thereby obtaining high-purity water. In contrast, the production process of pure water typically involves multiple steps such as distillation and ion exchange, which remove various impurities from the water through different physical and chemical methods.

2. Purity of water quality

The purity of RO water is usually above 90%, and it can effectively remove most impurities dissolved in water, but it cannot completely reach 100% pure water. Pure water, on the other hand, pursues higher purity, usually reaching over 99.9% with almost no impurities, making it a very pure water quality.

3. Differences in usage

Due to its relatively high purity, pure water is widely used in some fields that require extremely high water quality, such as in the laboratory for preparing experimental liquids and in the electronics industry for cleaning chips. Although RO water has high purity, its application areas are relatively wide, including drinking water and cooling systems in industrial production.

4. Cost and Feasibility

From the perspective of production cost, in general, the production cost of RO water is lower, while the production cost of pure water is relatively higher. This also makes RO water more economical and practical in some general application scenarios, while pure water is more used in special fields with extremely high water quality requirements.

Overall, although RO water and pure water are both products with excellent water quality after treatment, there are some differences in production process, water purity, use, and cost. When choosing to use, it is necessary to determine which type of water is more suitable based on specific needs.
