The best commercial RO systems are typically built to last for many years if they’re looked after properly. However, it’s important to know what to look for regarding industrial RO plant maintenance. Several components need to work in tandem in a water treatment plant. Having the right approach will help you identify and solve potential issues with your industrial RO system.
Firstly, we need to be familiar with how an RO system is meant to function during regular operation:
The unit will run quietly, free from excessive vibration and clicking “metallic” noises.
The pressure gauges will display steady values without pulsating
The exterior pump surfaces will be free from excessive mineral and salt deposits.
All high and low pressure fittings will be dry and free from leaks.
Problems Experienced with RO Systems
Now that we have a clear idea of how an industrial RO system is meant to function normally, we can take a look at some typical problems and their causes:
Unit Failing to Start
It’s possible that it may not be receiving power due to a blown fuse or any issue that interrupts the flow of electricity. The incorrect voltage at the power source can also prevent the unit from starting.
The unit will also fail to function properly due to low feedwater pressure. This can be due to a malfunctioning feed pump, clogged screens, and blocked inlets.
Unit Starts & Trips Out
This happens when the motor has been wired incorrectly, resulting in the motor rotation being off. It can also occur due to the motor receiving electricity at an improper voltage. Thermal overload on the starter motor can also result in the starter motor tripping.
Pressure Gauge Pulsating
In case the pressure gauge of your industrial RO system starts to pulsate, it is most likely due to a valve in the pump that is either stuck or broken.
Leaking or Whistling Pressure Control Valves
A loose gland nut in your industrial RO system can result in leaks and whistles from the pressure control valves.
Excessive Vibration
There can be a few reasons why an industrial RO system might vibrate excessively. Low feedwater flow can create heavy vibrations and knocking in the system pump. Owners should take note to avoid using the unit in this case as it will cause pump failure.
Be sure to position the unit on an even surface.
In case air manages to enter into the feedwater supply, it will again result in vibration and knocking. This can occur due to air entering feedwater lines, which can occur due to the feed pump receiving inadequate feed. Do not operate the unit in this situation. Instead, reach out to an expert.
Unusual Flavor or Odor in the Product Water
There may be various reasons for the unusual flavor or odor in the product water. Bacterial growth on the filter membrane is typically the reason for this. A saturated carbon cartridge can also result in the same issue, which can go away only with replacement.
Change in Permeate Quality/Flow
An increased feedwater salinity in your water treatment plant can affect the permeate quality and flow. Variations in water temperature can also lead to the same. If the membranes are fouled or are at the end of their product life, it will result in changed permeate quality. The problem will also arise in your industrial RO system if it has been recently preservatized.
