What is reverse osmosis?
Reverse osmosis is a membrane separation operation that uses pressure difference as a driving force to separate solvents from a solution. By applying pressure to the feed solution on one side of the membrane, water flows from the higher concentration side of the RO membrane to the lower concentration side, thereby separating fresh water from saline water. The filtered fresh water is called permeate water. The remaining concentrated water is called waste or saline water. Salt will be left behind, only clean water will flow through.
How does reverse osmosis work?
The working principle of the reverse osmosis system is to apply pressure to unfiltered water under the action of a high-pressure pump to obtain pure water, forcing the water to pass through the reverse osmosis membrane, filtering out almost all dissolved salts and other substances.
The reverse osmosis water treatment equipment uses sufficient pressure to separate the solvent in the solution through the reverse osmosis membrane in the opposite direction to the osmosis direction. The reverse osmosis method greater than osmotic pressure can be used to separate, purify and concentrate the solution. The reverse osmosis technology can effectively remove impurities such as dissolved salts, colloids, bacteria, viruses, bacterial endotoxin and most organic substances in the water, The main separation object of reverse osmosis membranes is the ion range in the solution, which can effectively remove salt from water without the need for chemicals. The desalination rate of the system is generally above 98%. So reverse osmosis technology is advanced, energy-saving, and environmentally friendly desalination method, and has become the mainstream pre desalination process.
Advantages of reverse osmosis
Due to the fact that RO reverse osmosis equipment does not require heating, consumes less energy, operates continuously and stably, has a small volume, simple operation, strong adaptability, and does not pollute the working environment, it has gradually replaced traditional ion exchange processes in the current field of water treatment equipment. The RO membrane components in RO reverse osmosis equipment use imported famous brand products, which not only have advanced technology, but also reliable product quality and strong scalability, Reasonable structure and small footprint, achieving a good balance between water utilization and product life, low energy consumption, fully automatic operation, and simple operation and maintenance.
