Discover the numerous benefits of clean water and stay informed on how to protect your loved ones. Dive in for essential tips and insights!

 

In our daily lives, we often hear about "RO membranes for water purifiers", "ultrafiltration membranes for water purification", "nanofiltration technology", etc., but what are the differences between these membranes? Today, we will take you to understand the application principles, performance, and scenarios of the two core filtration materials in the field of water purification technology, RO reverse osmosis membranes, ultrafiltration membranes, and nanofiltration membranes, to help you choose the most suitable water purification solution for you!

RO reverse osmosis membrane

RO reverse osmosis membrane is the guardian of extremely pure water, and it is a core component made by simulating semi biological semi permeable membranes. It can intercept all pollutants such as dissolved salts, heavy metals, bacteria, etc., and its desalination rate is astonishingly high at over 99%! Its pore size is only about 0.0001 micrometers, equivalent to one millionth of a human hair, and it is also the finest filtering pore size among the three.

Core ability: Deionize domestic water into pure water, achieving direct drinking water; Convert seawater into fresh water and produce purified water.

ultrafiltration membrane

Ultrafiltration membrane is the preserver of natural minerals. It uses physical screening mechanism and is a semi permeable membrane with a pore size of about 0.01 microns. It can accurately intercept harmful substances such as large organic molecules, colloids, bacteria, etc., while cleverly allowing minerals and ions to pass through smoothly. Its pore size is about 100 times that of an RO membrane, it does not require electricity, does not produce wastewater, and can effectively purify water while retaining beneficial minerals for the human body.

Core competency: Preserve natural minerals in water quality, remove sediment, rust, and bacteria.

Application scenarios: Home kitchen washing water, whole house water purification pretreatment, community drinking stations, washing machine inlet pretreatment. In industry, it is commonly used for food and beverage filtration, such as beer clarification processes and macromolecular separation in wastewater treatment.

Nanofiltration membrane

 

Nanofiltration membrane is a wise person in balancing purification and nutrition. The pore size of nanofiltration membrane is about 0.001 microns, and its performance is between RO membrane and ultrafiltration membrane, with a unique ability to selectively intercept substances. It can effectively remove some divalent ions (such as calcium and magnesium) while retaining monovalent ions (such as sodium), which can reduce water hardness and meet the demand for partially retaining minerals. It is an ideal choice for pursuing water quality balance.

Core competency: Softening water quality (removing scale components) while effectively retaining beneficial minerals.

Application scenarios: specialized water purifiers for mothers and infants, high-quality choices for water for infants and young children; In terms of industry, high-end bottled water production has performed well in food and pharmaceutical concentration, dye wastewater treatment, and other areas. In addition, it also has a special function of removing pesticide residues while retaining calcium and magnesium elements.

 

From these comparisons, you can clearly see that each of the three types of filter membranes has its own advantages

-If you are pursuing extremely pure water quality, RO membrane filtration membrane will be your best choice.

-If you want to preserve natural minerals, nanofiltration membranes are perfect for use in mother and baby water.

-If you only need basic filtration and want low cost, ultrafiltration membrane kitchen water purification equipment is your best partner.

Tip: When purchasing water purification equipment, it is recommended that you choose the appropriate technology type based on local water quality reports and regularly replace the filter membrane to ensure the water purification effect.
