What is Routine Chemical Analysis of Water?

Updated: May 6


Chemical Analysis of Water

Water may seem straightforward with its basic chemical composition of H2O, but there's a lot more to it beneath the surface. The quality of water is influenced by a myriad of factors, including dissolved solids, suspended solids, and chemicals, which differ based on the water's source.


For instance, groundwater will naturally contain elements absorbed from the Earth. Parameters like salinity, alkalinity, and hardness further define water's characteristics.


Why Should Water Analysis Be Carried Out?


Water, at its very essence, is a combination of H2O molecules. However, its intricate nature goes far beyond this basic elemental composition. Factors such as dissolved and suspended solids, along with various chemicals, significantly influence its quality. These constituents often vary based on the source of the water.


For instance, as groundwater travels through layers of earth, it naturally acquires elements from its surroundings. Moreover, specific attributes like salinity, alkalinity, and hardness offer more profound insights into the properties of a water sample. Delving deeper into these complexities necessitates routine chemical analysis, primarily for two main reasons:

  • Water Safety:

Consumption: Before water reaches our taps, it undergoes testing to ensure that all its parameters are within acceptable levels, making it safe for human consumption.

Recreational Use: Water in facilities like swimming pools undergoes rigorous testing to ensure chemical levels, such as chlorine, remain within the stipulated safe range, ensuring the well-being of swimmers and users.

  • Effective Treatment:

Analysis-driven Design: Before deciding on a treatment method, a comprehensive water analysis is performed. This detailed assessment ensures that the chosen treatment method aligns perfectly with the specific needs and characteristics of the water, guaranteeing optimal results.


Key Parameters in Routine Analysis

A standard chemical analysis of drinking water tests for a range of parameters, including colour, odour, turbidity, pH, alkalinity, calcium, chloride, conductivity, iron, magnesium, sulfate, total dissolved solids (TDS), total hardness, and calcium and magnesium hardness.


Understanding Basic Composition

Water is fundamentally H2O—two hydrogen atoms bonded to one oxygen atom. However, this basic molecule often carries with it a variety of other substances depending on its source.


Dissolved and Suspended Solids

Dissolved solids are the minerals and organic substances that are soluble in water. Groundwater, for instance, usually contains dissolved solids acquired from the soil and rocks it flows through. Suspended solids are small rocks, algea and other particles that are present in the water but do not dissolve with water. Suspended solids are usually separated through filtration processes.


Salinity, Alkalinity, and Hardness

The salinity of water can range from brackish to seawater, with each requiring a different type of RO system for effective treatment. Alkalinity measures the water's ability to neutralize acids, while hardness is generally an indication of calcium and magnesium ion concentration in water.


Conductivity

Conductivity indicates the water's ability to conduct an electric current. conductivity testing is an efficient way to determine the overall ionic concentration in water. The Myron L Ultramelter is an effective tool to measure conductivity. Read more here.


Conclusion

Routine chemical analysis is an essential step in the overall water treatment process. By understanding the various elements and conditions affecting water quality, we can make informed decisions on appropriate treatment methods. Always opt for a comprehensive water analysis before undertaking any water treatment actions. It’s also important to carry out regular analysis of the product water should be carried out to ensure the quality of water generated is consistent.

FAQs

  • What is the chemical analysis of water?

Chemical analysis of water involves testing for various elements and compounds, including minerals, ions, and organic substances, to determine its quality and suitability for different applications.


  • What is water routinely tested for?

Routine water testing generally includes checking for physical and chemical parameters like colour, odour, turbidity, and several ionic concentrations like calcium, magnesium, and chloride.


  • Why is water analysis important?

Water analysis is crucial for ensuring its safety and quality, determining the appropriate treatment methods, and meeting legal requirements for water quality.


  • How often should drinking water quality be tested?

The frequency of drinking water testing can vary depending on its source and application, but generally, it should be tested at least annually to ensure ongoing safety and quality.
