For different types of water, the limits of osmotic flux and elemental recovery in ro water treatment system are based on the correlation between SDI value and membrane contamination and the correlation between mineral content and elemental recovery respectively. For example, systems designed to have high permeability flux rates may experience higher scaling rates and more frequent chemical cleaning. The design of seawater systems is further limited by osmotic pressure and durability of membrane elements due to high salinity (> 36,000 PPM TDS).

Product Introduction of RO Water Treatment System
Design Features:
1. Achieve deep filtration of water by increasing the pressure on water. In addition to general filters, reverse osmosis pure water equipment also has fine filters, granular activated carbon filters and compressed activated carbon filters. The fine filter has a finer filtering function than the general filter, and can better filter impurities in the water. As we know, activated carbon has a good adsorption and filtration function for odors and impurities. The reverse osmosis pure water equipment uses double activated carbon filters to realize the deep filtration of raw water and improve the filtration efficiency of the equipment. At the same time, it is also an innovation to enhance the filtration capacity by increasing the pressure of the water.
2. The core of reverse osmosis pure water equipment is the application of reverse osmosis membrane. The reverse osmosis membrane is a filter membrane with extremely small pore size. Using this membrane can realize ultra-fine filtration of raw water, and can divide water into high concentration and low concentration at the same time. Water with a higher concentration can be recycled and reused, and water with a lower concentration is pure water that can be used by humans.
