Reverse osmosis (RO) systems are used to produce high purity water by filtering out silica, dissolved and suspended ions, organics, and ions from industrial feed water.
The industrial RO process produces highly pure water that can be utilized in the production of electronics and semiconductors, as well as the treatment of sanitary waste, by eliminating the salts, minerals, and other contaminants.
When using an industrial RO plant to treat water, one should be aware of the variables that affect the industrial RO plant's performance, to ensure that it operates as efficiently as possible.
Which factors impact the operation of industrial RO Plants?
In order for an Industrial RO system to run as efficiently as possible, a number of things must be taken into account during the design phase:
Pressure: As differential pressure builds up across the membranes, the system is burdened because permeate water is produced more slowly. The membranes must be cleaned or replaced more frequently, due to the increased strain on the system.
When the membranes need to be cleaned or replaced before they fail, a differential pressure measurement can be utilized to determine this. Several applications allow for the usage of a pressure transmitter. Be aware that if the process is stopped, the system may experience vibration and pressure surges that could cause issues.
Flow: Flow rates can show whether a pump or other piece of instrumentation, upstream of the RO system is malfunctioning. For instance, flow and differential pressure work together, to help identify membrane or filter clogging: low flow may signal a pump problem, while low flow and high DP may point to clogging.
Reduced throughput capacity and shortened runs are the results of improper flow rates and membrane fouling.
Temperature: The pressure that may be applied to the membranes is significantly influenced by temperature. Because, greater pressure is needed to force the water through the membrane as the water temperature drops, the flow of RO permeate falls as the water gets more viscous.
Since, water becomes less viscous at higher temperatures, less pressure is needed to create the same amount of permeate. The enhanced rates of diffusion result in higher total dissolved solids (TDS) in the permeate. Thus, monitoring and maintaining process temperature is crucial.
pH: The main benefit of detecting pH is its rapid response to pollution that may enter the process, during the creation and distribution of pure water. While, most applications do not notice a difference in pH changes, high-purity water processing depends on pH variations.
pH electrodes drift because clean water with low ionic strength has a poor conductivity, and a small buffering capacity. The resulting measurements are imprecise and non-reproducible. In addition to significant drift, other issues include poor temperature adjustment, and intolerable flow sensitivity.
Conductivity: A crucial indicator for an industrial RO system monitoring is conductivity. For a high-purity permeate to be produced, minor feed-water elements like ammonia and alkalinity, must be taken into consideration.
Typically, two conductivity measurements are used to calculate the overall effectiveness of dissolved solids removal: one at the entrance (cell 1) and one at the outflow (cell 2). This is calculated using the formula:
% rejection = [1-(cell2)/(cell 1)] x 100
