Applications of powdered sodium silicate in water purification
Powdered sodium silicate, also known as “water glass”, is a versatile chemical with wide applications in various industries. In this article, we will examine the characteristics of powdered sodium silicate and its role in water purification. Water treatment is one of the critical processes to ensure access to clean and safe water, and the use of appropriate chemicals in this process is very important.
Chemical and physical properties of powdered sodium silicate
Chemical composition
Sodium silicate powder is composed of sodium oxide (Na2O) and silicon dioxide (SiO2). The ratio of these two materials can be changed depending on specific needs and directly affect the final properties.
Physical properties
This substance is in the form of a white powder that easily dissolves in water and forms an alkaline solution.Among its prominent features are high adhesion, resistance to heat and pressure, and anti-corrosion properties.
The role of sodium silicate in water purification
Improving coagulation and coagulation
Sodium silicate is used as a coagulant in the water purification process. This substance improves coagulation and flocculation of suspended particles in water and, as a result, facilitates the sedimentation process.
Reduce water hardness
One of the important uses of sodium silicate in water purification is to reduce water hardness. This substance reacts with calcium and magnesium ions and forms insoluble compounds that can be easily removed.
Preventing pipe corrosion
Due to its anti-corrosion properties, sodium silicate plays an important role in preventing the corrosion of pipes and equipment used in water purification systems.This material prevents direct contact of water with metal by forming a protective layer on metal surfaces.
Removal of heavy metals
Sodium silicate is effective in removing heavy metals such as lead, cadmium and mercury from water. This substance reacts with heavy metals and forms insoluble compounds that are easily separated from water.
Specific applications of sodium silicate in water purification
drinking water purification
In the purification of drinking water, the use of sodium silicate as a coagulating agent and water hardness reducer can provide a significant improvement in water quality.
Industrial wastewater treatment
In industrial wastewater treatment, sodium silicate is used as an effective substance in removing heavy metals and reducing chemical oxygen demand (COD). This material reacts with organic materials and heavy metals and forms insoluble compounds that are easily separated from wastewater.Boiler water treatment
In boiler systems, the use of sodium silicate can help prevent the formation of deposits and corrosion. By forming a protective layer on the internal surfaces of the boiler, this material prevents direct contact of water with metal, and as a result, the useful life of the equipment increases.
Methods of using sodium silicate in water purification
Direct addition method
In this method, sodium silicate is added directly to water. This method is simple and effective and is widely used in drinking and industrial water purification.
Use of ready solutions
In some cases, ready-made solutions of sodium silicate are used for ease of use and more precise control. These solutions are connected to automatic injection systems and continuously added to the water flow.Combination with other chemicals
In some water purification processes, sodium silicate is used along with other chemicals such as polyelectrolytes and coagulants. These compounds can significantly improve the efficiency of the treatment process.
Advantages of using sodium silicate in water purification
- Increasing the efficiency of coagulation and coagulation processes
