For different kinds of pollutants, we can adopt various techniques of elimination techniques. Below are a number of typical methods and concepts of sodium silicate option.

Rainfall technique
The precipitation method is an approach that uses contaminations ions to react with particular chemical reagents to generate difficult rainfall so as to eliminate it from the sodium silicate remedy. As an example, for metal ions such as iron ions and light weight aluminum ions, alkaline reagents such as salt hydroxide or potassium hydroxide can be added to 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 form carbonate precipitation. The response formula is as complies with:
CA ₃ ² ⁻ + Co c → CACO ₃ ↓
Mg ₃ ² ⁻ + Co m → mgco ₃ ↓
The rainfall method is straightforward and the cost is reduced, yet you require to pay attention to the quantity and response problems of the sediment to make sure that the contaminations ions can be totally precipitated.
Ion exchange method
The ion exchange method is to precisely adsorb and trade the ions in the service with an ion exchange material to remove the technique of contaminations ions. Ion exchange resin is a polymer product with an ion exchange function. It can trade responses with the ion in the service, soak up impurities ions to the material, and preserve the helpful ions in salt ions in sodium silicate service in the remedy.
The ion exchanges are good and can eliminate a variety of pollutants ions, yet the rate of ion exchange resin is higher, and regeneration is called for regularly.

Membrane splitting up
The membrane splitting up approach uses the semi-diaphragm to uniquely go through the various components in the service so regarding accomplish the method of separation and removal. Depending on the diameter size and separation concept of the membrane, the membrane layer separation technique can be divided right into several types, such as microfiltration, ultrafiltration, filtering and turn around osmosis.
For impurities such as insoluble solid granules and macromolecular organic matter in salt silicate option, mini fillets or ultrafiltration membranes can be used for eliminating; impurities ions of some tiny molecules can be eliminated with the purification or reverse osmosis membrane layer. The membrane splitting up method has the benefits of basic operation, high separation performance, and reduced power usage.
