For various types of contaminations, we can adopt different techniques of elimination approaches. Below are a number of usual approaches and principles of salt silicate remedy.

Precipitation approach
The rainfall approach is an approach that uses pollutants ions to react with particular chemical reagents to produce challenging precipitation so regarding remove it from the sodium silicate remedy. For instance, for metal ions such as iron ions and aluminum ions, alkaline reagents such as salt hydroxide or potassium hydroxide can be added to create it. The response formula is as follows:
Fe ⁻ + 3oh f → Fe (OH) ↓
Al ⁻ + 3oh a → Al (oh) ↓
For calcium and magnesium ions, carbonate reagents such as salt carbonate or potassium carbonate can be contributed to create carbonate precipitation. The reaction equation is as complies with:
CA ₃ ² ⁻ + Carbon monoxide c → CACO ₃ ↓
Mg ₃ ² ⁻ + Carbon monoxide m → mgco ₃ ↓
The rainfall technique is simple and the cost is reduced, but you need to take note of the amount and reaction conditions of the sediment to make sure that the impurities ions can be completely precipitated.
Ion exchange method
The ion exchange technique is to uniquely adsorb and exchange the ions in the service with an ion exchange material to eliminate the approach of impurities ions. Ion exchange resin is a polymer product with an ion exchange feature. It can exchange reactions with the ion in the service, take in impurities ions to the material, and keep the helpful ions in salt ions in salt silicate option in the remedy.
The ion exchanges are excellent and can eliminate a range of impurities ions, however the price of ion exchange resin is greater, and regrowth is needed frequently.

Membrane layer separation
The membrane layer splitting up approach utilizes the semi-diaphragm to uniquely travel through the various elements in the service so as to achieve the method of separation and elimination. Depending on the diameter dimension and separation concept of the membrane layer, the membrane separation method can be split right into several kinds, such as microfiltration, ultrafiltration, purification and turn around osmosis.
For impurities such as insoluble solid granules and macromolecular organic matter in sodium silicate service, micro fillets or ultrafiltration membrane layers can be made use of for removing; contaminations ions of some tiny particles can be gotten rid of with the purification or reverse osmosis membrane. The membrane splitting up method has the advantages of basic operation, high splitting up efficiency, and reduced energy consumption.
