High Total Dissolved Solids (TDS) in water is caused by both natural sources (minerals from rocks, soil) and human activities (agricultural runoff, industrial discharge, sewage). TDS includes inorganic salts, minerals, metals, cations, and anions that are dissolved in water.

How do I reduce the TDS of water?

How to Reduce TDS in Water?

  1. Reverse Osmosis (RO) Systems: The most effective method, where water passes through a semi-permeable membrane that filters out up to 95–99% of TDS.
  2. Distillation: Involves boiling water and condensing the steam.

What causes TDS values to increase?

High TDS (Total Dissolved Solids) in drinking water can result from a mix of natural and man-made sources. Common causes include minerals like calcium, magnesium, and sodium from rocks and soil, as well as contaminants from agricultural runoff, industrial waste, sewage, and even seawater intrusion in coastal areas.

Are TDS in water harmful?

The EPA recommends keeping TDS under 500 parts per million (ppm) for the best taste and quality. Once levels rise beyond 500 ppm, there's a greater chance of potentially harmful contaminants that can make water unsuitable for drinking.

Why is TDS higher in filtered water?

Ionic adsorption, a process used by BOROUX Foundation Filters, may alter the charge of water, leading to higher TDS readings even when no contaminants are present. This occurs because the filters absorb negative ions, leaving positive ions to pass through, which are then measured as total dissolved solids.

Does boiling water reduce TDS?

No, boiling water does not reduce TDS. It may even increase concentration as water evaporates, leaving dissolved solids behind. To lower the TDS level, methods like reverse osmosis, distillation, or deionisation are necessary.

Does high TDS mean hard water?

High TDS in water typically means you're going to have hard water. Hard water is water that contains an abundance of mineral solids, like calcium and magnesium. While hard water minerals are not damaging to human health, they can wreak havoc on your pipes and water-using appliances.

Does bottled water have TDS?

In the U.S., bottled water must contain at least 250 mg/l TDS to be labeled as mineral water. TDS above 500 mg/l qualifies a water as "low mineral content" while more than 1,500 mg/l allows a "high mineral content" label. Distilled water has a TDS of 0 mg/l; seawater has about 34,000mg/l.

How do I lower my TDS?

How to Reduce TDS in Water---5 Ways

  1. Using a Reverse Osmosis System to Decrease TDS of Water. ...
  2. Using an Ion Exchange to Lower the TDS in Water. ...
  3. Distilling Water to Remove TDS from Drinking Water. ...
  4. Using Activated Carbon Filter to Lower TDS in Drinking Water. ...
  5. Installing a Water Softener to Reduce Water TDS Level.

What are common sources of TDS in water?

The constituents of TDS can also be measured individually. TDS in water supplies originate from natural sources, sewage, urban and agricultural run-off, and industrial wastewater. Salts used for road de-icing can also contribute to the TDS loading of water supplies.

How much TDS does RO remove?

RO water purifiers are ideal for high TDS (up to 1000 mg/L), removing excess salts via a semipermeable membrane. UV and UF purifiers are effective for low TDS (below 200 mg/L), ensuring microbial safety without altering mineral content.

How to remove TDS without RO?

Water softeners play a key role by using ion exchange to reduce minerals like calcium and magnesium—common contributors to both hardness and TDS. While they don't remove all dissolved solids, softeners help improve appliance efficiency and reduce scaling issues.

Does lemon reduce water hardness?

Lemon juice is rich in citric acid, which can react with the minerals in hard water. This reaction forms soluble compounds, making those pesky minerals less of a problem—at least on surfaces.

What are 20 ways to save water?

20 Ways to Save Water

  • Use a displacement device (a water-filled bottle) in the toilet tank to reduce the amount of water required to flush.
  • Use toilet only for its intended purpose. ...
  • Repair leaky taps or toilets immediately. ...
  • Consider a small capacity toilet when replacing an old one.
  • Take shorter showers.

How to reduce TDS in water naturally?

Distillation

Another popular method for addressing high levels of TDS is distillation. Distillation helps remove organic and inorganic substances from water by boiling it until the water evaporates.

Which water purifier is best for TDS 500?

If your TDS Level in PPM is between 150-300, that means your water quality is good. Thus, opt for a UV or UV UF water purifier. If your TDS Level in PPM is between 300-500, that means your water quality is acceptable. Thus, opt for RO+UV or RO+UF water purifiers.

What are the side effects of high TDS water?

High TDS can lead to health issues like kidney stones, digestive problems, and dehydration. It also causes scaling in appliances, reducing their efficiency and lifespan. An RO water purifier helps reduce excess TDS and protect both your health and appliances.

Will boiling water remove TDS?

No, boiling water does not remove TDS (Total Dissolved Solids). Boiling kills bacteria and viruses, making the water microbiologically safe, but it does not eliminate dissolved salts, heavy metals, or other contaminants. In fact, boiling can increase the TDS concentration as water evaporates.

How much TDS is ok in drinking water?

The TDS levels of water are measured by PPM (Parts Per Million). The water with a TDS value range between 50-150 PPM is considered excellent for drinking, 150-250 is good, 250-300 is fair, 300-500 is unsafe, and above 1200 means unacceptable.

Do water filters remove TDS?

To effectively reduce TDS, you have to use a filtration system that specializes in dissolved solids. For example, reverse osmosis (RO) systems, distillation units or deionization (DI) filters. For home use, RO systems are the most common and effective, removing 95-99% of TDS, including heavy metals and salt.

How can I check my TDS status?

What is the best pH for drinking water?

The US Environmental Protection Agency (EPA) recommends that town water pH should range between 6.5 and 8.5, with most town water averaging around 7.5. Common bottled waters are usually close to neutral at a pH of 7.0. Bottled alkaline water has a higher pH between 8 and 9.

Is bottled water low in TDS?

Most bottled waters fall within a TDS range of 50 to 800 mg/l (Acqua Panna, 188 mg/l; Fiji, 210 mg/l; Evian, 357 mg/l; Perrier, 475 mg/l), but many well-known waters have a much higher TDS (San Pellegrino, 1,109 mg/l; Badoit, 1,200 mg/l; Contrex, 2,032 mg/l; Gerolsteiner, 2,527 mg/l).
