1. General information about industrial reverse osmosis systems<\/b><\/span><\/h2>\n

Below is some general information about <\/span>industrial reverse osmosis systems<\/b> that is of great interest to many people. In particular, this technology will bring safe and quality water to users.<\/span><\/span><\/p>\n

1.1 What are industrial reverse osmosis systems?<\/b><\/span><\/h3>\n

Water purification technology <\/b>(Reverse Osmosis) is a water purification technology that works based on reverse osmosis. With the use of an ultra-thin osmosis membrane that only small molecules pass through, it helps to screen up to 99.99% of harmful substances in water, including all impurities in water such as viruses, and bacteria. , toxic chemicals, … RO technology will produce pure water that can be used immediately and does not need to be boiled again. Currently, this technology is applied in-home water purification equipment, factories, and large factories that need to use pure water in their products.<\/span><\/span><\/p>\n

1.2 Advantages and disadvantages of RO technology<\/b><\/span><\/h3>\n

Currently, RO technology is widely used, to better understand the application and advantages and disadvantages of the technology. This technology compares to other technologies such as EDI, UF,… you can refer to it in the following table.\u00a0<\/span><\/p>\n\n\n\n\n\n\n\n\n

Completely removes harmful bacteria, impurities, fungi, remaining 0.2 – 2.0% of the impurities. single ion with very small size (small 0.1 – 0.5 nanometer). This outlet water does not retain beneficial minerals.<\/span><\/td>\n

Ultra-Pure Water<\/b><\/span><\/p>\n

Completely removes bacteria, impurities, dirty fungi, solids and even ions. This outlet water retains beneficial minerals.<\/span><\/td>\n<\/tr>\n

Advantages<\/span><\/strong><\/p>\n<\/td>\n

\n
    \n
  • Significant energy and operating costs savings.<\/span><\/li>\n
  • Applying mechanical filtration method should not change the chemical properties of the water source.<\/span><\/li>\n
  • Compact system, simple structure, saving installation space.<\/span><\/li>\n
  • There is no waste water as much as the RO pure water filtration system saves a lot of money for users.<\/span><\/li>\n
