For different kinds of impurities, we can adopt various techniques of elimination techniques. Right here are a number of usual approaches and concepts of sodium silicate option.

Precipitation technique
The rainfall method is a method that makes use of contaminations ions to respond with specific chemical reagents to generate challenging rainfall so as to eliminate it from the sodium silicate service. For example, for metal ions such as iron ions and aluminum ions, alkaline reagents such as salt hydroxide or potassium hydroxide can be added to develop it. The response equation is as adheres to:
Fe ⻠+ 3oh f → Fe (OH) ↓
Al ⻠+ 3oh a → Al (oh) ↓
For calcium and magnesium ions, carbonate reagents such as sodium carbonate or potassium carbonate can be contributed to develop carbonate precipitation. The reaction formula is as adheres to:
CA ₃ ² ⻠+ Co c → CACO ₃ ↓
Mg ₃ ² ⻠+ Carbon monoxide m → mgco ₃ ↓
The precipitation technique is straightforward and the cost is reduced, yet you need to take note of the amount and response conditions of the sediment to make sure that the contaminations ions can be entirely precipitated.
Ion exchange approach
The ion exchange method is to precisely adsorb and exchange the ions in the option with an ion exchange material to remove the approach of pollutants ions. Ion exchange resin is a polymer product with an ion exchange feature. It can trade reactions with the ion in the option, take in impurities ions to the material, and preserve the helpful ions in salt ions in salt silicate service in the remedy.
The ion exchanges are excellent and can get rid of a selection of impurities ions, yet the price of ion exchange material is higher, and regeneration is called for frequently.

Membrane layer separation
The membrane layer splitting up technique makes use of the semi-diaphragm to precisely travel through the various parts in the remedy so as to accomplish the approach of splitting up and elimination. Depending on the diameter size and separation principle of the membrane layer, the membrane splitting up method can be divided right into numerous types, such as microfiltration, ultrafiltration, purification and reverse osmosis.
For pollutants such as insoluble strong granules and macromolecular organic matter in sodium silicate service, micro fillets or ultrafiltration membranes can be utilized for removing; impurities ions of some small molecules can be gotten rid of with the filtration or turn around osmosis membrane layer. The membrane layer splitting up approach has the advantages of basic procedure, high splitting up effectiveness, and low energy intake.
