Minimum TDS for Drinking Water: Understanding Safe TDS Levels

What is TDS in Drinking Water?

TDS (Total Dissolved Solids) refers to the concentration of dissolved substances in water, including minerals, salts, and organic compounds. It is measured in ppm (parts per million) and determines the purity and taste of drinking water. High TDS levels may indicate contamination, while low TDS may lead to a lack of essential minerals.

Minimum TDS for Drinking Water

The minimum TDS for drinking water varies based on regional standards and individual preferences. While ultra-pure water has a TDS close to 0 ppm, it may lack essential minerals needed for human health. WHO suggests a minimum TDS level of 50 ppm to maintain necessary mineral content.

Minimum TDS for Drinking Water in India

According to the Bureau of Indian Standards (BIS), the recommended drinking water TDS level should be between 50-500 ppm. However, the most ideal range for safe and healthy drinking water is 150-250 ppm. Water with a TDS below 50 ppm may lack essential minerals like calcium and magnesium, leading to potential health issues over time.

Minimum TDS for Drinking Water in Liters

When calculating TDS per liter, it’s essential to ensure that the water retains essential minerals. A TDS below 100 ppm per liter is considered too low and may require remineralization to maintain proper mineral balance. Water with a TDS level of 150-300 ppm per liter is generally considered safe and nutritious for regular consumption.

Minimum TDS for Drinking Water in PPM

The minimum TDS for drinking water in ppm should ideally be above 50 ppm to ensure the presence of essential minerals. Water with a TDS level below 30 ppm may taste flat and lack essential nutrients, while water exceeding 500 ppm may contain excessive salts and minerals, affecting taste and safety. A well-balanced TDS level enhances hydration and improves taste.

Minimum TDS for Drinking Water Calculator

A TDS meter is used to check the drinkable water TDS and ensure it falls within a safe range. Using a TDS calculator, you can estimate TDS by considering the conductivity of water. High-precision digital meters can provide an accurate drinking water TDS limit. Most RO purifiers reduce TDS significantly, and adding a remineralization filter can help maintain a healthy balance.

Ideal Drinking Water TDS Range

The drinking water TDS range can be classified as follows:

• Less than 50 ppm – Low mineral content, not ideal for long-term consumption.

• 50-150 ppm – Moderately pure, requires remineralization.

• 150-250 ppm – Ideal drink water TDS range, balanced mineral content.

• 250-500 ppm – Acceptable but may have a slightly salty taste.

• Above 500 ppm – Not recommended for drinking without filtration.

Maintaining a proper drinking water TDS level is essential for good health, as an imbalanced TDS can affect hydration, digestion, and nutrient absorption.
