How does multi-stage filtration work in RO systems?

Multi-stage filtration in the RO system is achieved through a series of filter elements and membrane components with different functions. This is a carefully designed process designed to thoroughly purify water quality and ensure the provision of clean and safe drinking water. The entire filtration system includes pre-filter, granular activated carbon filter element, RO membrane filter and post-activated carbon filter element. Each level has its own unique functions and effects.

The first is the pre-filter, which is usually the first line of defense in the system. It is mainly used to remove large impurities, sediment, rust particles and other substances in the water to prevent these impurities from causing damage to subsequent filters and RO membranes and protect them. normal operation of the system. Granular activated carbon filter element, its main function is to absorb residual chlorine, organic matter, odor, etc. in the water, and improve the taste and taste of the water quality. This step is particularly effective in removing odors and bad taste from the water, improving the quality of the water.

Then there is the RO membrane filter, which is one of the core components of the RO system. Through the selective separation of the semi-permeable membrane, the RO membrane can remove harmful substances such as tiny particles, heavy metals, microorganisms, organic matter, bacteria, viruses, etc. in the water, achieving deep purification of water quality.

Finally, there is the post-activated carbon filter element, which further absorbs and removes odors, residual chlorine and other substances in the water, improves the taste and purity of the water, and ensures the quality of the final drinking water produced.
