Total Dissolved Solids (TDS) in Water: The Science Behind it and How to Reduce its Levels for Safe Consumption

Total dissolved solids (TDS) is a term used to describe the amount of inorganic and organic substances present in water, including minerals, salts, and other compounds. The presence of TDS in water can affect its taste, odor, and overall quality. In this blog, we will explore the science behind TDS in water, sources of TDS, health effects of high TDS levels, how to measure TDS, safe and unsafe TDS limits, and methods to reduce TDS levels for safe consumption.

What are Total Dissolved Solids (TDS)?

Total dissolved solids (TDS) refer to the concentration of inorganic and organic compounds in water that can pass through a filter. It is measured in parts per million (ppm) or milligrams per liter (mg/L). TDS in water can come from various sources, including natural processes such as weathering of rocks and minerals, industrial activities, and human activities such as agriculture and waste disposal.

Sources of TDS in Water

The sources of TDS in water can vary depending on the location and the type of water source. Groundwater sources such as wells and boreholes typically have higher TDS levels than surface water sources such as rivers and lakes. The TDS levels in groundwater are often influenced by the presence of minerals such as calcium, magnesium, and sodium, which can dissolve in water. Surface water sources, on the other hand, can be affected by agricultural activities, industrial discharges, and runoff from urban areas.

How to Measure TDS in Water

TDS can be measured using a TDS meter, which is a handheld device that measures the electrical conductivity of water. The TDS meter provides a reading in parts per million (ppm) or milligrams per liter (mg/L). The higher the TDS levels, the higher the electrical conductivity of the water.

TDS Levels in Drinking Water - Safe and Unsafe Limits

The safe and unsafe TDS limits in drinking water can vary depending on the country and the regulatory authority. In the United States, the Environmental Protection Agency (EPA) has set a maximum contaminant level (MCL) of 500 ppm for TDS in drinking water. The World Health Organization (WHO) recommends a TDS limit of 1,000 ppm for drinking water. However, some studies suggest that TDS levels above 300 ppm can affect the taste and odor of water.

How to Reduce TDS Levels in Water - Methods and Techniques

Reverse osmosis is our recommended way to remove TDS from water. Reverse osmosis is a process that uses a semipermeable membrane to remove dissolved solids from water. The water is forced through the membrane, leaving behind the dissolved solids. 

Importance of Water Filtration Systems in Reducing TDS Levels

Water filtration systems are essential in reducing TDS levels in drinking water. Reverse osmosis systems, distillation systems, and deionization systems are all effective in reducing TDS levels. These systems can be installed in homes, offices, and other buildings to provide safe drinking water. Some water filtration systems also have additional features such as activated carbon filters, which remove chlorine and other organic substances from water.

Conclusion: Importance of Monitoring TDS Levels in Water for Safe Consumption

In conclusion, monitoring TDS levels in water is essential for safe consumption. High TDS levels can affect the taste, odor, and overall quality of water, and can also have adverse health effects. It is important to measure TDS levels in drinking water and ensure that they are within safe limits. Water filtration systems such as reverse osmosis, distillation, and deionization systems are effective in reducing TDS levels and providing safe drinking water. As responsible consumers, we should be aware of the TDS levels in our drinking water and take necessary measures to ensure safe consumption.
