Though we all know that drinking pure water is necessary, few of us are knowledgeable in the technical language of a water purifier. There are numerous aspects which determine the performance of a water purifier, especially an RO machine. But when you are about to install a RO device, it is necessary to know all the factors well. Otherwise, you may not understand how to maintain the efficacy of your water-purifying device.
To know the factors that affect the functions of a RO device, it is important to know the work procedure of a RO device. The work procedure of a RO device depends on various aspects. All of them are divided into two factors. Numerous traits of feedwater and the installation of the system. This is because there are numerous types of feedwater and each of them can make the RO device function differently.
For each type of water, the rejection and water flow of the RO device are distinct. The different traits of feedwater are temperature, pH, pressure, percentage recovery, salt concentration etc. So let’s focus on these aspects well so that you can understand the functions of a RO purifier well. You can buy your preferred RO device from any reputed water purifier service in Meerut.
Temperature
The very first factor that affects the functions of a RO device is the temperature. The operating temperature of a RO device has an immense consequence on its water flow. The more temperature you set for the device, the more permeate flow boosts with that simultaneously. If the feedwater has more density and a higher diffusion rate, it helps the water flow through the RO membrane more effectively. If the temperature increases by 1°C, the permeate flow increases by 3%.
Most manufacturers and suppliers of RO devices deliver temperature correction tables which can help you in a more detailed way. The temperature of a RO device not only determines how much water passes through the device. It also decides the amount of salt that would pass through the membrane. RO devices are mainly of two types, commercial and residential. Commercial RO membrane becomes warmer due to hot feedwater. This boosts the salt dilution procedure.
Pressure
Now the next factor that impacts the RO function is NDP or net driving pressure. NDP is the total amount of pressure that the RO membrane face while running. If an NDP gets doubled in a commercial RO device, the water flow in it also gets doubled. In a RO device, clean water passes through the RO membrane while feedwater passes through the filter.
For this reason, the number of pollutants gets increased in the feed water. This is one of the prime reasons behind the increased TDS percentage. The intake feed TDS is always lower than an outlet permeate. For this reason, there is always a discrepancy between the output and input pressure.
Salt Concentration
The next major aspect that affects the work procedure of a RO device is the salt concentration. The salt concentration determines the amount of TDS on the feed side and the permeate side. Water pressure has no impact on salt concentration. If the feed pressure increases, the salt concentration of the permeate decreases.

pH Level
Another considerable aspect is the pH level that can affect the work procedure of a RO device. TFC membrane or thin film composite membrane delivers a more stable pH range in comparison with CA or cellulose acetate membrane. The salt rejection capacity of a membrane depends on its pH level. So it’s better to select the TFC membrane over the CA membrane.
Percent Recovery
The next major aspect that can make your RO device work properly is the percent recovery. Now, what is that? If you divide the permeate flow by the feed flow rate and then multiplied it by 100%, you can get percent recovery. Though the other aspects which we have discussed are constant. But the percent recovery completely relies on the permeate flow rate and percent rejection. If the percent recovery is low then more water would get depleted from the device.
So these are some major characteristics that impact the functions of a RO device notably. So whoever you would buy a RO device, consider this article for sure.
