For different types of contaminations, we can take on different techniques of elimination approaches. Below are several usual methods and concepts of salt silicate remedy.

Rainfall approach

The precipitation technique is a technique that makes use of impurities ions to react with specific chemical reagents to create difficult rainfall so regarding remove it from the salt silicate service. As an example, for metal ions such as iron ions and aluminum ions, alkaline reagents such as salt hydroxide or potassium hydroxide can be contributed to form it. The reaction formula is as adheres to:

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 added to create carbonate rainfall. The reaction equation is as adheres to:

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

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

The rainfall method is basic and the price is reduced, however you need to focus on the amount and reaction conditions of the debris to guarantee that the contaminations ions can be totally precipitated.

Ion exchange method

The ion exchange approach is to uniquely adsorb and trade the ions in the service with an ion exchange resin to remove the technique of pollutants ions. Ion exchange material is a polymer material with an ion exchange function. It can trade reactions with the ion in the option, soak up pollutants ions to the material, and maintain the useful ions in salt ions in salt silicate solution in the remedy.

The ion exchanges are good and can remove a selection of contaminations ions, however the price of ion exchange resin is higher, and regeneration is required routinely.

Membrane separation

The membrane layer splitting up approach makes use of the semi-diaphragm to uniquely pass through the various elements in the solution so regarding accomplish the method of splitting up and elimination. Depending upon the diameter size and splitting up principle of the membrane, the membrane layer splitting up method can be separated right into several types, such as microfiltration, ultrafiltration, filtration and turn around osmosis.

For contaminations such as insoluble strong granules and macromolecular raw material in salt silicate solution, micro fillets or ultrafiltration membranes can be utilized for removing; pollutants ions of some little particles can be gotten rid of with the filtration or reverse osmosis membrane layer. The membrane separation technique has the advantages of straightforward operation, high splitting up effectiveness, and reduced energy usage.
