Are you concerned about the quality and safety of your drinking water? Learning how to reduce TDS (Total Dissolved Solids) in water can help you achieve cleaner, healthier, and better-tasting water.
To reduce TDS in water, use a reverse osmosis system or a water softener. Both remove hardness, which is a type of TDS, very well. RO systems also remove contaminants and salts. Alternatively, try a distillation unit or ion exchange process for cleaner and safer drinking water.
In this comprehensive guide, we will explore various methods to lower TDS levels, including reverse osmosis systems, distillation units, and ion exchange processes. By understanding these techniques and choosing the right one for your needs, you’ll be on your way to enjoying pure, refreshing water in no time. So, let’s dive in and discover the key to transforming your tap water.

Understanding TDS: A Brief Overview
Before diving into the methods to reduce TDS in water, let’s take a moment to recap what TDS is and why it matters.
Total Dissolved Solids (TDS) refer to the inorganic salts and small amounts of organic matter present in water, including calcium, magnesium, sodium, potassium, and various other compounds. High TDS levels can affect the taste, odor, and overall quality of your drinking water, potentially leading to health issues.
TDS increases as soil and minerals dissolve in water as it flows through mineral-rich rocks, metallic pipes, and other surfaces. However, TDS can also be introduced into water through sources like water treatment chemicals, agricultural chemicals, road salts, and heavy metals.
While TDS isn’t always a bad thing, high TDS levels in drinking water can indicate the presence of dangerous dissolved impurities. Here are some ways in which high TDS can affect our daily lives:
- Water’s taste: High TDS levels in water can give it a bitter, sulfuric, or salty taste, depending on which dissolved salts and ions are present.
- Cooking: Using water with high TDS levels for cooking can alter the taste of food, and some people may find it unappetizing.
- Cleaning: High TDS concentration in water can leave difficult-to-clean stains on clothing and white spots on dishware, and mineral deposits on surfaces that come into contact with water, making cleaning more challenging and time-consuming.
- Health: Not all TDS components are natural nutrients. Some dissolved substances, like hazardous chemicals and inorganic substances, can have adverse health effects on our bodies.
- Plumbing: When water passes through our plumbing and appliances, it leaves behind TDS deposits, affecting the durability of our pipes and other fixtures.
Evaluating TDS Levels in Drinking Water
Understanding the TDS levels in your drinking water is essential for maintaining water quality and ensuring its safety. The TDS concentration is typically measured in milligrams per liter (mg/L) or parts per million (ppm). Here’s a breakdown of TDS levels and what they indicate:
- Low TDS (0-150 ppm): Soft water with a fresh taste, but may lack essential minerals.
- Moderate TDS (150-500 ppm): Ideal for drinking, as it contains a balanced amount of minerals and salts.
- High TDS (500-1,200 ppm): Elevated mineral content, which may impart a salty or bitter taste to the water and increase the risk of scaling in pipes.
- Very High TDS (above 1,200 ppm): Not recommended for drinking due to excessive mineral content and potential health risks.
It’s important to regularly test your water’s TDS levels to ensure it remains within the safe and recommended range for consumption.
Top Methods to Lower TDS in Your Drinking Water
In this section, we’ll explore the most effective ways to reduce TDS levels in water, ensuring a healthier and better-tasting drinking experience. Each method has its unique advantages, so consider your specific needs and water quality when choosing the best solution.
Method 1: Reverse osmosis systems
Reverse osmosis (RO) is a popular and highly effective method for reducing TDS levels in water. RO systems use a semi-permeable membrane to filter out contaminants, including dissolved salts and minerals. They provide a high level of purification, making them ideal for households with significantly high TDS levels.

Method 2: Water softeners
Water softeners are an excellent option for reducing TDS levels caused by an excess of calcium and magnesium. These devices use an ion exchange process to replace hard minerals with sodium or potassium ions, resulting in softer water with a lower TDS level. While water softeners may not remove all TDS components, they can significantly improve water quality, especially in areas with hard water.

Method 3: Distillation
Distillation is a simple yet effective method to reduce TDS in water. The process involves heating water to produce steam, which then condenses into pure water, leaving behind contaminants and dissolved solids. Distillation units can be installed at home to provide clean, low-TDS drinking water, but keep in mind that this method may also remove beneficial minerals.
Method 4: Deionization
Deionization, also known as ion exchange or demineralization, is a process that removes dissolved ions from water, effectively reducing TDS levels. This method utilizes ion exchange resins that attract and bind to positively and negatively charged ions, removing them from the water. Deionization is a powerful method for TDS reduction, but it’s often used in conjunction with other purification systems for optimal results.
By understanding these methods and choosing the right one for your needs, you’ll be well on your way to enjoying pure, refreshing water with lower TDS levels.

Frequently Asked Questions about TDS in Water
Why are my water’s TDS levels so high?
High TDS levels can result from various factors, including natural sources, agricultural runoff, industrial waste, and water treatment processes. Hard water, which contains high levels of calcium and magnesium, is also a common cause of elevated TDS levels.
How can I test my water’s TDS?
You can test your water’s TDS levels using a handheld TDS meter or by sending a sample to a certified laboratory for analysis. Regular testing is essential to ensure your water remains within the safe and recommended range for consumption.
How much TDS in water is safe for drinking?
Water with a TDS level between 150 and 500 ppm is generally considered ideal for drinking, as it contains a balanced amount of minerals and salts. However, the World Health Organization (WHO) states that water with TDS levels up to 1,000 ppm is still acceptable for consumption.
How can I reduce TDS naturally?
To reduce TDS levels naturally, consider using rainwater harvesting systems, which collect rainwater with lower TDS levels than groundwater or surface water sources. Alternatively, you can also try using activated carbon filters to remove some organic contaminants and improve taste, though they may not significantly reduce TDS levels.
Does boiling my water reduce TDS?
Boiling water does not reduce TDS levels, as it only kills bacteria and other pathogens. TDS components, such as dissolved salts and minerals, remain in the water even after boiling.
Does a UF (Ultrafiltration) filter reduce TDS?
A UF filter can remove suspended particles, bacteria, and viruses, but it doesn’t significantly reduce TDS levels, as it doesn’t remove dissolved salts and minerals.
Does a UV (Ultraviolet) water purifier remove TDS?
A UV water purifier effectively kills bacteria, viruses, and other microorganisms, but it doesn’t reduce TDS levels, as it doesn’t filter out dissolved solids.
Does a water softener reduce TDS?
Water softeners can reduce TDS levels caused by an excess of calcium and magnesium by replacing these hard minerals with sodium or potassium ions. While they may not remove all TDS components, they can significantly improve water quality, especially in areas with hard water.
Final Take
Understanding how to reduce TDS in water is essential for ensuring the quality, safety, and taste of your drinking water. Various methods, such as reverse osmosis, water softeners, distillation, and deionization, can effectively lower TDS levels to provide you with clean, refreshing water.
It’s important to test your water’s TDS levels regularly and choose the most suitable method based on your specific needs and water quality. By taking action to reduce TDS, you’ll be well on your way to enjoying healthier and better-tasting drinking water for you and your family.
