Keep it below 0.2 mg/l
It mainly forms a compound with aluminum and sodium, which deposits within the membrane. Damage to membrane structures. It is generally kept at 2.3 mg/l.
Silica levels are generally kept at 2.3 mg/l. Excess silicon content affects current efficiency, and its presence also increases the degree of damage caused by calcium and magnesium to the ion membrane. It is important to control the pH level of the saline solution so that it does not become too high, as well as the silicon content in the source water.
