For different kinds of impurities, we can embrace different approaches of removal approaches. Right here are numerous usual approaches and concepts of sodium silicate service.

Rainfall approach

The precipitation technique is a technique that uses contaminations ions to react with particular chemical reagents to produce tough precipitation so regarding eliminate it from the sodium silicate solution. For instance, for steel ions such as iron ions and light weight aluminum ions, alkaline reagents such as sodium hydroxide or potassium hydroxide can be contributed to develop 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 salt carbonate or potassium carbonate can be added to form carbonate rainfall. The response formula is as follows:

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

Mg ₃ ² ⁻ + Co m → mgco ₃ ↓

The rainfall approach is easy and the price is reduced, but you need to focus on the quantity and reaction problems of the debris to make sure that the impurities ions can be totally precipitated.

Ion exchange technique

The ion exchange technique is to uniquely adsorb and exchange the ions in the solution with an ion exchange resin to remove the method of contaminations ions. Ion exchange resin is a polymer product with an ion exchange function. It can trade responses with the ion in the remedy, absorb pollutants ions to the resin, and maintain the beneficial ions in salt ions in salt silicate service in the option.

The ion exchanges are great and can get rid of a selection of impurities ions, but the rate of ion exchange resin is higher, and regrowth is required frequently.

Membrane splitting up

The membrane layer separation technique makes use of the semi-diaphragm to uniquely pass through the different elements in the option so regarding achieve the approach of splitting up and removal. Depending upon the diameter dimension and separation concept of the membrane, the membrane layer splitting up approach can be separated right into numerous types, such as microfiltration, ultrafiltration, purification and reverse osmosis.

For impurities such as insoluble solid granules and macromolecular organic matter in salt silicate solution, mini fillets or ultrafiltration membrane layers can be made use of for getting rid of; contaminations ions of some small molecules can be gotten rid of with the filtration or reverse osmosis membrane layer. The membrane splitting up method has the advantages of easy operation, high splitting up effectiveness, and reduced energy usage.
