Blockage in the sodium carbonate pipeline of the brine treatment system

Is it caused by pipe corrosion or liner peeling, or is it due to crystallization?
Could it be that the concentration of sodium carbonate is too high? Our company uses a 10% concentration!
Is it caused by loose frayed edges from the编制 bag falling into the preparation tank during setup? Or, when the water hardness is high (e.g., high calcium content), precipitates such as calcium carbonate are formed; over time, these accumulations can clog the pipes.
Is it clogged due to crystallization? We’ve encountered this problem too； You should lower the concentration. And then there’s what those few people mentioned above

Our company uses pure water to prepare a 10% sodium carbonate solution; it has never caused any blockages. I wonder what the problem is in your case
The 10% solution does not crystallize at temperatures of 10 degrees or higher. Based on your current conditions, the concentration is 15%, and the crystallization temperature is around 16 degrees. Therefore, you can reduce the concentration. If the winter temperatures in your area are quite low, you may even need to employ electric tracing or insulation measures.
We often experience blockages; usually, they’re caused by items like pockets or other debris. As winter approaches, it’s also important to pay attention to controlling the concentration
1. Blockages occurring outside the brine are likely due to an excessively high concentration. 2. Blockages within the brine occur in sections of sodium carbonate pipelines submerged in brine; if calcium carbonate formed as a result of reactions deposits on the pipe walls, it can eventually cause blockages over time. We do regular cleanups.
1. Generally, this is caused by high concentration or low temperatures; it’s advisable to reduce the concentration slightly and use steam tracing when it’s cold. 2. To prevent blockages caused by debris such as pockets of material, a filter can be installed at the pump inlet.
