How to Lower High TDS Level in Bore Water for Domestic Use

Your home might depend on bore water for all your daily needs, but if the water has a high Total Dissolved Solids (TDS) level, it can lead to several issues, including taste, odor, and scaling problems in your plumbing. Thankfully, there are effective methods to lower the TDS level in your bore water. This article will guide you through the process using a combination of settling, filtration, and coagulation techniques. Let’s dive in!

Understanding TDS in Bore Water

Total Dissolved Solids (TDS) are the minerals and salts dissolved in the water. High TDS levels can result from poor water quality or overuse of fertilizers and chemicals in the area. For domestic water use, it is advisable to keep the TDS level below 500 mg/L for optimal quality and taste.

Treating Bore Water for TDS

Given the limited space in bore wells, it is more practical to treat the water externally. Here’s a step-by-step guide to reduce the TDS level effectively:

1. Settling

The first step in the purification process is sedimentation. This involves letting the water settle in a large tank to allow suspended particles to separate and settle at the bottom of the tank. Depending on the amount of suspended solids, this process can take several days to weeks.

2. Filtration

After the settling process, the next step is filtration. There are several filtration options available, but you can use a combination of coagulation and coagulant agents to further purify the water. Ferric sulfate, aluminum sulfate, and ferric chloride are commonly used coagulants. These chemicals help to coagulate and precipitate the suspended solids, making them easier to remove.

3. Sand and Gravel Filters

For municipalities and city corporations, traditional filtration methods include the use of sand and gravel filters. These filters effectively trap and remove contaminants from the water, ensuring a higher level of purity. While this method might require more space and maintenance, it is highly effective in reducing TDS levels.

Ultimately, the best method for you will depend on your specific needs and the amount of water you plan to treat. Consulting with a water treatment expert can help you choose the most appropriate method. Here’s a summary of the key steps in the process:

Set the water in a large tank for sedimentation. Add coagulant agents to the water to coagulate and precipitate suspended solids. Use sand and gravel filters to remove the contaminants from the water.

Conclusion

By following these steps, you can effectively lower the TDS level in your bore water for domestic use, ensuring that your water is safe and enjoyable to drink. Remember that regular maintenance and monitoring of the TDS level are crucial to maintaining water quality.
