How does the mini RO water purifier work?

Mini RO water purifier is a highly efficient water treatment device that utilizes reverse osmosis technology to effectively remove contaminants from water and provide clean and safe drinking water. The following is a detailed explanation of the working principle and process of mini RO water purifier:

Pre-treatment stage:Water first goes through a pre-treatment stage, which usually includes a pre-filter or cartridge. These filters are used to remove large particles, sediment, rust and other impurities from the water to prevent them from damaging the subsequent RO membrane.

RO membrane filtration stage:The pre-treated water enters the RO membrane filtration stage. The RO membrane is a key component of the mini RO water purifier, and it is a semi-permeable membrane with tiny pores. These pores are smaller than water molecules and can block most of the ions, molecules and microorganisms dissolved in the water, thereby isolating the pollutants in the water.

Pressure driven:Mini RO water purifiers usually require external pressure to drive water through the RO membrane. This overcomes the osmotic pressure of the RO membrane and allows water molecules to pass through the RO membrane, while pollutants are retained on the other side of the RO membrane.

Wastewater discharge:During the RO membrane filtration process, in addition to producing purified water, a part of concentrated wastewater is also produced, which contains the filtered pollutants. This wastewater is discharged from the system to ensure the efficiency and performance of the RO membrane filtration.

Post-treatment stage:Some mini RO water purifiers may also be equipped with post-treatment filters, such as activated carbon filters, to further remove odors, color and residual pollutants from the water, thereby improving the water quality.

Storage and supply:After a series of filtration steps, the purified water is stored in the water tank of the water purifier and supplied to the user through a faucet or outlet.

Mini RO water purifiers effectively remove pollutants from water through multiple steps such as pre-treatment, RO membrane filtration, pressure driven, wastewater discharge and post-treatment, to obtain clean and safe drinking water. This working principle makes mini RO water purifier an efficient and reliable water purification device that can meet the needs of homes and offices for pure water.
