Electrodeionization system<\/i><\/b><\/a> (EDI water system)\u00a0is an advanced technology that removes most impurities in water, creating High purity water sources of up to 99.9%, ensuring safety for users. In the field of wet towel production in particular and the production of skin care products in general, water plays a vital role in determining the quality of products, so it is essential for businesses to invest in a sound water filtration system. absolutely necessary. Below is a detailed share of today’s leading water filtration technology.<\/span><\/i><\/p>\n

1. Working mechanism of EDI water purification technology<\/strong><\/h2>\n

EDI (Electrodeionization) technology means Vietnamese – “electrodeization”. <\/span>The mechanism of action of this scientific invention is through electrolysis of water, splitting H2O water molecules into H+ and OH- ions, removing ions – especially mineral ions (such as sodium, calcium, copper cations… ) and anions (such as chloride, nitrate, etc.). These ions are closely related to atopic dermatitis problems.<\/span> This is considered the most modern water purification system used for water treatment in manufacturing.<\/span><\/p>\n

Purified water<\/b><\/span><\/p>\n

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

99.9% ultra-pure water<\/b><\/span><\/p>\n

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

Advantages<\/span><\/td>\n\n
    \n
  • Significant energy and operating cost savings.<\/span><\/li>\n
  • Applying the 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 RO pure water purification system, saving users and protecting the environment.<\/span><\/li>\n
  • Simple operating process.<\/span><\/li>\n<\/ul>\n<\/td>\n
\n
    \n
  • Output water quality meets the standards of the Ministry of Health of Vietnam. The water source, after being purified, is used for direct drinking, not boiling.<\/span><\/li>\n
  • Optimum filtration capacity.<\/span><\/li>\n
  • Receives many different input water sources.<\/span><\/li>\n
  • The system is durable and must not be regularly maintained or replaced.<\/span><\/li>\n
  • The price is not too expensive.<\/span><\/li>\n<\/ul>\n<\/td>\n
\n
    \n
  • The EDI process does not need to use regenerative chemicals<\/span>, so the water source is highly safe.<\/span><\/span><\/li>\n
  • EDI filtration system wastewater can be recycled and reused.<\/span><\/li>\n
  • The EDI system does not require shutdown to reproduce.<\/span><\/li>\n
  • EDI equipment has continuous regeneration, so clean water quality is more stable than other water purification systems, with resistivity up to 18.25\uff2d\u03a9\u00b7cm, creating a source of water that meets ultra-clean water standards.\u00a0<\/span><\/li>\n<\/ul>\n<\/td>\n<\/tr>\n
Limitations<\/span><\/td>\n\n
    \n
  • Cannot be filtered with input water sources such as hard water, salt water, or brackish water.<\/span><\/li>\n<\/ul>\n<\/td>\n
\n
    \n
  • The amount of wastewater is also equivalent to the amount of purified water that is purified, causing water waste.\u00a0<\/span><\/li>\n
  • Requires electricity to operate.<\/span><\/li>\n<\/ul>\n<\/td>\n
The investment cost for the EDI system is high.<\/span><\/td>\n<\/tr>\n
Application in production<\/span><\/td>\n\n
    \n
  • Pretreatment, protective filtration for RO systems<\/span><\/li>\n
  • Sterilization and concentration for the food and beverage industry, separation and filtration for dairy production, pharmaceutical industry, biology.<\/span><\/li>\n<\/ul>\n<\/td>\n
\n
    \n
  • Producing pure bottled drinking water.<\/span><\/li>\n
  • Medicine.<\/span><\/li>\n
