Reverse osmosis device is an integral part of contemporary wastewater treatment technology, widely used in a variety of fields, including industrialized water solutions and civil life water purification treatment. What exactly is a reverse osmosis plant? What is its working principle? Here we will analyze the basic principle, structure, main use and key role in modern society of reverse osmosis device.

First, the working principle of reverse osmosis device
RO (reverse osmosis) is a use of differential pressure to promote water from a highly concentrated aqueous solution (or high pressure aqueous solution) according to the semi-permeable membrane into a lower concentration of aqueous solution (or low pressure aqueous solution) separation process. In this process, the water can be smoothly according to the semi-permeable membrane, and most of the carbonates, organic compounds, bacteria and other impurities dissolved in the water are also blocked, thus realizing water purification treatment.

Second, reverse osmosis device structure design
Reverse osmosis device is mainly composed of several major parts such as pretreatment system, high pressure water pump, ro reverse osmosis membrane parts, control system and post-treatment system, etc.
1. The main role of the pretreatment system is to carry out a comprehensive solution to the source water, remove suspended particles, colloidal solutions and organic compounds and other debris in the water in order to safeguard the ro reverse osmosis membrane parts will not be environmentally contaminated and damaged. Common preparatory treatment methods are activated carbon filter, quartz sand filter and water softening equipment, etc.
2. high pressure water pump is an indispensable part of the reverse osmosis device, which undertakes to increase the water after preparatory treatment to a specific working pressure, thus prompting the water according to the ro reverse osmosis membrane. High-pressure pump performance on the reverse osmosis device water production capacity and the actual effect of desalination has a direct impact.
3. reverse osmosis device components is the key part of the reverse osmosis device, a number of reverse osmosis membrane components. ro reverse osmosis membrane is a special construction of semi-permeable membranes, can be in a high-pressure environment to allow water according to the water at the same time blocking the impurities in the water.
4. automatic control system: automatic control system to undertake monitoring and adjusting the operating status of the reverse osmosis device. Automatic control system: The automatic control system is responsible for monitoring and adjusting the operation status of the reverse osmosis device to ensure the safe and efficient operation of the equipment. This mode usually includes PLC (programmable controller), touch screen, sensors and components.
5. post-treatment system: post-treatment system to ro reverse osmosis water for further production and processing, in order to meet the different uses of water quality testing standards. The more common post-treatment process has ultraviolet sterilization, ozone sterilization and activated carbon filtration.


Third, the application of reverse osmosis device industry
1. Industrialized water: reverse osmosis device in the industrial field has been widely used, including power engineering, electronic devices, chemical plants, pharmaceutical industry and other fields. These areas of water demand is extremely strict, need to reasonably remove a variety of impurities in the water positive ions, in order to ensure the stability of the process and the quality of the product.

2. life water purification treatment: with the improvement of people's living ability, people for drinking water regulations are increasingly improved. Reverse osmosis device can quickly eliminate water impurities, viruses and heavy metals and other harmful gases, and thus enhance the safety of drinking water. At this stage, many families have installed home use reverse osmosis water purifier to ensure drinking water health and safety.
3. Desalination equipment is one of the key methods to deal with the pollution of water resources around the world. Membrane separation technology is one of the main technologies of seawater desalination equipment, which has the advantages of high efficiency, energy saving and environmental protection. Relying on the reverse osmosis device, the sea surface can be transformed into water that people can utilize.
4. Wastewater treatment: Membrane separation technology has been widely used at the level of wastewater treatment. The application of reverse osmosis device can be an all-round solution for chemical wastewater and domestic wastewater treatment, removing harmful substances in the water, so as to realize the utilization of sewage resources and environmental protection.
