After taking a lengthy TDS reading, you might feel insecure for sure. But, purchasing a TDS meter and taking the readings means reducing the TDS value of water and then drinking. Therefore, you should not worry, although you get a high TDS value.

There are certain ways to reduce the TDS of water. In this small guide, we will tell you the ways to perform TDS reduction.

Ion Exchange

As one of the water treatment methods, Ion exchange may perform TDS reduction. The process of Ion exchange happens in water with ions of the same charge from a resin.

The used resin must contain ions that are opposite in charge to the ions in water. As a reaction, the TDS may reduce as water passes through the resin bed.

Activated Carbon Filtration

Among the ways to perform TDS reduction, Activated carbon filtration is the most popular method. Water is passed through an active carbon filtration that involves impurity and solid absorption. The more the activated carbon surface area gets, the higher the TDS reduction.


Water boiling is the best way to reduce the TDS of drinking water. After boiling, the TDS in water gets sedimented on the bottom of the container that you used to boil water. You can use this cost-effective and simple method to reduce TDS.

Using a Reverse Osmosis (RO) System

The RO systems or Reverse Osmosis (RO) Systems are considered the perfect choice for reducing TDs in water on a large scale. Reverse Osmosis (RO) Systems use a semipermeable membrane for filtration. They take out impurities and contaminants, organic and inorganic matters that increase the TDS of water.


Distillation is crucial when it comes to the TDS reduction back to zero and getting pure water. Water is boiled until the steaming point and then condenses back to liquid form, which creates water that has zero or almost zero TDS water. The impurities and contaminants will remain in the boiling chamber.

Adding Zeolite

Treating water with Zeolite is also an effective way to reduce the TDS of water. Zeolite is a natural mineral that absorbs impurities and reduces TDS levels in the water.

Due to the high ion exchange capacity, the absorption ability of the substance increases. It must be conducted under a regulated atmosphere, and the user must follow regulated calculations when adding Zeolite.

What are the Optimum Levels of TDS in Drinking Water?

Optimum tds levels in drinking water refer to the ideal range of total dissolved solids. These levels, typically measured in parts per million (ppm), ensure water quality and pose no health risks. The suitable range varies based on water sources and intended use. For instance, drinking water should ideally have TDS levels between 150 to 300 ppm.

Adding Lime

Adding Lime to water was used in the ancient world, especially in Eastern culture. It also can help reduce TDS levels, increase water quality, and make it consumable for men. The Lime can react with the dissolved solids and then produce solid compounds on the bottom of the container.
