Reasons for the excessive SIO2 level in the brine fed into the ion exchange membrane cell

The SIO2 level in the brine fed into the ion exchange membrane is too high
One is brought in by the raw salt； The other is brought in by the brine solution ； Another possibility is related to the material used in the equipment of the salt dissolving tank or basin; check these three main reasons.
It has been determined that it is caused by raw salt; thank you all for your advice!
We encountered a situation with high silicon content once, which was caused by the lack of proper shielding in the salt dissolving tank during the sandblasting rust removal process for brine treatment equipment; high silicon levels are generally attributed to the salt itself.
1. The level of water-insoluble substances in the raw salt must not exceed the specified limit. 2. Pay attention to pH control in the salt treatment process.
