Water that is independent of microbiological, chemical, and physical pollution is regarded as safe drinking water. Contaminated water can be hazardous to one's health in a number of ways. Some pollutants, such as pathogenic microorganisms and harmful metals, are deadly. Other pollutants, on the other hand, that do not pose a health concern, such as bad taste caused by excessive iron levels, can make water unpleasant to drink.

Water treatment at NETSOL WATER SOLUTION ensures water is free from all the harmful contaminants and is safe for drinking.

TYPES OF TEST FORMAT FOR WATER QUALITY

• 1. Test strip: A test strip is a single-use strip that changes colour based on theconcentration of particular chemicals in water. These strips are tiny in size, inexpensive, and widely accessible on the market.
• 2. Color disc test kits: A colour disc test kit offers many chemical assays in addition to a basic test strip approach. This form of analysis is more expensive and complex than a test strip, but it produces more accurate findings.
• 3. Handheld digital instrument: Digital metres, colorimeters, and photometers are small and portable, making them ideal for testing. They offer precise findings.

WATER QUALITY CAN BE CHECKED ON 3 BASIS

• 1. Microbial invasion:When water sources come into touch with faeces, the presence of microorganisms (pathogens) increases. Salmonella Typhi and Vibrio cholera, which cause typhoid fever and cholera, are two typical instances.

• 2. Chemical contamination:The presence of metals, organic compounds, and other dangerous substances that are detrimental to one's health. Water may be chemically polluted both naturally and by human activity, such as the mixing of industrial and agricultural waste in the water. Chemicals such as salt and chlorine pose no health risks. Long-term use of some chemically polluted water, on the other hand, can have serious consequences for human health, particularly in children.

• 3. Physical contamination: The existence of colour, odour, cloudiness, and temperature in water indicates physical contamination. The majority of them are not harmful to one's health. Their presence in the water, though, might make it unpleasant to drink.

HOW WATER QUALITY SHOULD BE MEASURED?

• 1. Temperature testing: This type of testing is used to assess the rate of biochemical reactions on water in an aquatic setting. When the temperature rises too high, the water's ability to contain oxygen declines and the organism's ability to withstand contaminants decreases.
• 2. Dissolved Oxygen testing: This is best done in water with a calibrated dissolved oxygen sensor. Water at a lower temperature should contain more oxygen, but dirty water should have less. Dissolved oxygen concentrations in healthy water are typically greater than 6.5-8mg/L and between 80-120 percent.
• 3. pH testing: This type of testing measures the acidic level of water. Generally, 6.5 -8.5 pH level is considered best for safe drinking water.
• 4. Salinity testing: This is done to determine how much salt has dissolved in the water. Typically, salinity is determined by indirectly measuring the electrical conductivity of the water.
• 5. Chloride testing: Due to mineral dissolution and industrial contamination, the levels of chlorine in the water have also grown. There are several simple methods for testing residual chlorine, including strip tests, colour discs, and via kits.
• 6. Metal testing: This analysis indicates the existence of metals that do not exist naturally in water. Metals such as aluminium, arsenic, copper, lead, mercury, tin, and nickel can enter the water from natural sources or human activity such as mining. Water polluted with heavy metals can damage the kidneys, liver, and neurological system.
• 7. Turbidity testing: It determines the number of suspended particles in water or the clarity of the water. If there is a significant degree of turbidity, a powerful water treatment is necessary to make the water safe.
• 8. Nitrate testing: High levels of nitrates are connected with pollution caused by agricultural fertiliser and animal manure. Furthermore, latrines, landfills, and industrial waste are linked to nitrogen contributions in water. As a result, constant nitrogen monitoring to ensure water quality is critical. High nitrate levels in drinking water can create taste and odour issues.

CONCLUSION

People have grown more aware about cleanliness and safety after COVID-19 hit the world, giving rise to bottled drinking water. One may meet rising demand and make substantial money by establishing a NETSOL WATER SOLUTION PLANT in their Industries, Companies, Organisations.
