For various sorts of impurities, we can take on different approaches of removal approaches. Here are numerous common approaches and principles of salt silicate solution.

Precipitation technique

The rainfall approach is a method that utilizes contaminations ions to react with specific chemical reagents to produce hard rainfall so regarding remove it from the salt silicate solution. For instance, for metal ions such as iron ions and aluminum ions, alkaline reagents such as salt hydroxide or potassium hydroxide can be included in form it. The response formula is as complies with:

Fe ⁻ + 3oh f → Fe (OH) ↓

Al ⁻ + 3oh a → Al (oh) ↓

For calcium and magnesium ions, carbonate reagents such as sodium carbonate or potassium carbonate can be included in create carbonate precipitation. The reaction formula is as complies with:

CA ₃ ² ⁻ + Carbon monoxide c → CACO ₃ ↓

Mg ₃ ² ⁻ + Carbon monoxide m → mgco ₃ ↓

The rainfall approach is simple and the price is low, yet you require to pay attention to the amount and response conditions of the sediment to ensure that the contaminations ions can be completely precipitated.

Ion exchange technique

The ion exchange approach is to precisely adsorb and exchange the ions in the solution with an ion exchange resin to get rid of the method of pollutants ions. Ion exchange resin is a polymer material with an ion exchange feature. It can exchange reactions with the ion in the service, take in pollutants ions to the material, and retain the beneficial ions in salt ions in salt silicate option in the solution.

The ion exchanges are excellent and can eliminate a variety of contaminations ions, however the rate of ion exchange resin is higher, and regrowth is required consistently.

Membrane separation

The membrane layer splitting up method utilizes the semi-diaphragm to selectively go through the various elements in the option so regarding accomplish the technique of splitting up and removal. Depending upon the diameter dimension and separation principle of the membrane, the membrane separation approach can be split right into a number of types, such as microfiltration, ultrafiltration, purification and turn around osmosis.

For contaminations such as insoluble solid granules and macromolecular organic matter in sodium silicate solution, mini fillets or ultrafiltration membrane layers can be made use of for getting rid of; impurities ions of some small particles can be removed with the purification or reverse osmosis membrane layer. The membrane layer separation technique has the advantages of straightforward procedure, high separation efficiency, and reduced power intake.
