Sodium permanganate is one of the chemical oxidants that exists as a liquid solution. It is commonly used in chlorinated solvent remediation and water treatment. The inorganic compound formula of this solution is NaMnO4. The sodium permanganate is dark purple. Most researchers conclude that the compound is a crystalline solid with powerful oxidizing properties.
NaMnO4 forms a deep purple solution; hence it is highly soluble in water. Most industries use it as an oxidizing agent. Some of these industries are agriculture, water treatment industries, and laboratory applications, among others. The Sodium Permanganate solutions are effective in removing organic compounds such as manganese, iron, and even hydrogen sulfide from various water sources. This helps in reducing the contaminants in water.
The latest uses of NaMnO4 include:
Water treatment
The strong oxidizing properties of the solution make it more effective to be used in water treatment. It helps in removing some organic components such as manganese and iron. These contaminants contribute to water odor, taste, and even discoloration. The solution can treat wastewater, well water, and groundwater.NaMnO4 solution is also used in the disinfection of water and to control bacterial growth. Water quality is enhanced since some debris, such as algae, bacteria, and biofilm, are easily removed using the solution.
The solution was added early in the treatment process. The permanganate oxidation is followed by filtration, granular activated carbon, and chlorine disinfection. Some factors, such as pH and temperature, influence the solution’s effectiveness. The dosage levels of the NaMnO4 used in water treatment need to be controlled. You need to monitor the concentration of the solution at the application point. Concentrations exceeding the predetermined threshold will indicate overdosing; hence, the dosage must be adjusted. Continuous agitation is required to help disintegrate the organic material produced by the bacteria and the sediment. This will help in achieving treatment effectiveness.
Permanganate sensors, which use light absorbance at various wavelengths, can be used to sense the permanganate levels. Additional reference wavelengths compensate for some compounds that may interfere with the measurements. Some of these components may include sand particles. The sensor is designed with a distinctive long path length measurement cell that helps detect the range and sensitivity required in consumed water. The result will be reliable and assist in providing real-time measurement of the permanganate in water.
The permanganate residual may give the water some pink color, but this does not affect the taste of the water; hence it does not cause any health issues or interfere with the plumbing system.
The NaMnO4 supplies should be refilled as part of the maintenance schedule. If you are using the solution in the well, then periodic treatment is required to dissolve the mineral scale and the iron deposits. You must consult a water treatment specialist since regular treatment requires strong acids.
Final words
In conclusion, NaMnO4 is commonly used in water treatment because of its oxidizing property. It would help if you were careful when using the solution since it is poisonous and can cause some skin irritations. Always ensure you use the correct dosage when during the water treatment process. You can consult a water treatment specialist if you need to use the solution for water treatment.
