In water filter terms, reverse osmosis (or hyper-filtration) is the process of filtering water under pressure through a semi-permeable membrane, allowing water to pass through but rejecting other particles such as bacteria, toxins, salts, and anything bigger than around 150 Daltons.
What is RO (Reverse Osmosis)?
Reverse Osmosis is water filterization system using Membrane Filter with numerous tiny holes so that it could filter metal liquid and virus. When passing through the filter, they will stick to the surface of Membrane Filter (The water for this Membrane filter process must be water without suspended solids. And before passing through Membrane filter, it has to pass through 3 types of normal filter.) So, the water needs to get an appropriate amount of force from booster pump to be able to pass through Membrane Filter (Typically Membrane filter allows only small water molecule passing through but not bacteria, virus and metal liquid with complicated molecule). The detect particle is gotten rid of in form of waste water while the purified water will be filtered again by activate Carbon to make sure that water from Reverse Osmosis is clean and clear.
