The method and principle of sodium silicate solution removal nano fibers
For various sorts of pollutants, we can adopt different techniques of removal techniques. Right here are several usual techniques and concepts of salt silicate solution.

Rainfall approach
The rainfall approach is a method that makes use of impurities ions to respond with particular chemical reagents to produce difficult rainfall so as to eliminate it from the salt silicate solution. As an example, for steel ions such as iron ions and aluminum ions, alkaline reagents such as salt hydroxide or potassium hydroxide can be included in develop it. The reaction 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 added to form carbonate rainfall. The reaction equation is as adheres to:
CA ₃ ² ⁻ + Co c → CACO ₃ ↓
Mg ₃ ² ⁻ + Co m → mgco ₃ ↓
The precipitation method is simple and the cost is reduced, however you need to take notice of the quantity and reaction problems of the debris to guarantee that the contaminations ions can be entirely precipitated.
Ion exchange method
The ion exchange technique is to uniquely adsorb and trade the ions in the remedy with an ion exchange material to get rid of the method of contaminations ions. Ion exchange material is a polymer material with an ion exchange function. It can trade reactions with the ion in the remedy, take in contaminations ions to the resin, and maintain the useful ions in salt ions in sodium silicate option in the option.
The ion exchanges are excellent and can eliminate a range of contaminations ions, however the cost of ion exchange material is higher, and regrowth is required on a regular basis.

Membrane separation
The membrane layer splitting up technique makes use of the semi-diaphragm to uniquely travel through the various elements in the option so as to accomplish the approach of splitting up and elimination. Relying on the diameter dimension and splitting up concept of the membrane layer, the membrane layer separation approach can be split right into a number of types, such as microfiltration, ultrafiltration, filtration and turn around osmosis.
For impurities such as insoluble solid granules and macromolecular raw material in sodium silicate option, micro fillets or ultrafiltration membrane layers can be used for removing; impurities ions of some little particles can be removed with the filtering or turn around osmosis membrane. The membrane layer splitting up method has the benefits of simple procedure, high separation effectiveness, and low energy consumption.
