RO low pressure membrane: Widely used in many fields to create efficient and energy-saving water resources solutions

First, RO low pressure film working principle and characteristics

RO low pressure membrane is based on the principle of reverse osmosis, through the application of external pressure to make water molecules from the high concentration side through the semi-permeable membrane to the low concentration side, while most ions, organic matter, bacteria, viruses and so on are effectively blocked by the membrane. Compared with the high-pressure film, the main feature of the low-pressure film is that it can achieve the separation process at a lower operating pressure (usually in the range of 0.5 to 1.6MPa), thus significantly reducing the operating energy consumption. In addition, the low-pressure film usually has a high water production flux, can produce more purified water per unit time, and can still maintain a high desalination rate when dealing with low salinity and low hardness water sources. These characteristics make RO low pressure films show remarkable applicability in many fields.

Second, RO low pressure film in various fields of application and its advantages

Drinking water purification: In the home, office and community and other places, RO low pressure film is widely used in direct drinking water dispensers, household water purifiers, can effectively remove the residual chlorine in tap water, heavy metals, organic matter, microorganisms, etc., to provide safe and healthy drinking water. Its lower operating pressure not only reduces energy consumption, but also makes the device quieter, more compact and more suitable for home use.

Food and beverage industry: In the process of food processing and beverage production, RO low-pressure film is used to prepare pure water or ultra-pure water as raw material water or cleaning water. Its energy-saving characteristics help companies reduce operating costs, while stable water quality guarantees product quality and taste. In addition, for juice, tea and other direct drinking liquid food, RO low pressure film can also remove harmful ingredients in raw water, improve product quality.

Agricultural irrigation: In modern agriculture, RO low-pressure membranes are used to treat groundwater, surface water or reclaimed water to produce water quality suitable for crop irrigation. The high-yield water flux provided by the low-pressure membrane with low energy consumption can meet the irrigation needs of large areas of farmland, while reducing the potential impact of salt and harmful substances on soil and crops, which is conducive to sustainable agricultural development.

Pharmaceutical industry: In the pharmaceutical, medical device cleaning, laboratory pure water preparation and other links, RO low-pressure film is used to prepare process water with high purity requirements. Its high desalinization rate ensures the purity of the water and meets the strict pharmacopoeia standards and GMP requirements. At the same time, the energy-saving characteristics help reduce the environmental burden of enterprises, in line with the trend of green manufacturing in the pharmaceutical industry.

Light industry wastewater treatment and reuse: For the wastewater produced by light industry such as electroplating, printing and dyeing, leather, RO low-pressure membrane can be used as a deep treatment unit to effectively remove salt and organic matter in wastewater, achieve standard discharge or return to the production process. In the treatment of low salt wastewater, the low energy consumption advantage of low pressure membrane is particularly obvious, which helps enterprises to realize waste water resources and reduce fresh water consumption.

Third, RO low pressure film application value and future prospects

Energy saving and consumption reduction: RO low-voltage film consumes lower energy during operation, which helps users and enterprises reduce operating costs, in line with the global trend of energy saving and emission reduction. In the context of increasingly tight water resources, its energy-saving characteristics are of great significance to promote the efficient use and sustainable management of water resources.

Equipment simplification and cost control: Because the low pressure film does not need high pressure pumps and high strength pressure vessels, the equipment structure is relatively simple, and the initial investment and maintenance costs are low. This allows RO technology to be popularized in a wider range of scenarios, especially for small and medium-sized enterprises or areas with limited resources, providing an economically viable water treatment solution.

Technological innovation and market expansion: With the progress of membrane material science and the optimization of membrane making process, the future RO low-pressure membrane is expected to further improve the separation efficiency, reduce energy consumption and extend the service life on the basis of maintaining the existing advantages. This will promote its application in more emerging fields, such as new energy, environmental protection, fine chemicals and other industries, and broaden the market space.

To sum up, RO low-pressure membrane with its advantages of efficient separation under low pressure, energy saving and consumption reduction, equipment simplification, etc., is widely used in drinking water purification, food and beverage industry, agricultural irrigation, pharmaceutical industry and light industry wastewater treatment and reuse and other fields. It has played an important role in improving water resource utilization efficiency, ensuring water quality safety, promoting environmental protection and economic benefits, and has shown broad market prospects and far-reaching social value. With the continuous innovation of technology and the continuous growth of market demand, the application field of RO low pressure film will be further expanded, contributing to the construction of green, saving and intelligent water resources management system
