There are two water purification processes called RO (Reverse Osmosis) and UP (Ultrafiltration). RO refers to the process of desalinating seawater and filtering out organic matter, while UP is a high-quality water system that filters out water used for domestic wastewater treatment. To understand RO and UP better, here is a brief overview of these concepts for you. What is RO? RO works by semi-permeable membranes through which only water molecules can pass while the ions, organics, and microbe are blocked. This water purification method removes not only contaminants but also some useful components that contribute to better health results. The purified water is completely safe, ultra-pure, clean, transparent and highly purified. Below are the key elements of the filtration process. 1. Suspended Particles RO effectively reduces the risk of suspensions of microbes, organics, and minerals found naturally throughout the water environment. When suspended particles are taken out from surface water sources through the RO membrane, microscopic dust is easily removed. Suspensions reduce significantly from microlevels due to dissolved particles or organic compounds extracted from water sources. As a result, ultra-pure water remains free of any impurities, resulting in excellent clarity.

RO finds applications in

Laboratories Medical facilities Electronics manufacturing Semiconductor industry What is UP? UP stands for Ultrafiltration. It applies a membrane that has bigger holes to block the way for: Macromolecules Colloids Microorganisms This process remove bad materials but leaves us minerals we need, generating clean and freshly-tasting drinks. UP helps Beverage production Food processing Life sciences 化学 industry Key Differences UP vs RO The only difference lies in: Filtration precision

RO membranes (0.001 μm)

Remove nearly all impurities

Produce highest purity water

Remove both beneficial and harmful minerals

UP membranes (0.01-0.1 μm)

Remove larger contaminants

Retain beneficial minerals

Ideal for improving taste and safety of drinking water

Here is the decision guide you need: Select RO when you want pure water only, i.e., it will serve only for laboratory and electronics (applications where there can be no mineral in drinking water) Select UP when you want ultra-fresh, mineral-rich, high quality drinking water Both RO and UP document they produce "ultrapure water" but actually: RO produces true ultra-pure water UP produces purified good tasting drinking water and retains minerals.
