How To Reduce TDS In Drinking Water

TDS is a measurable number suggesting the level of severity of the dissolved salt. This number depends on the water source, supply, and use. Water found at the source, i.e., glaciers have a lower TDS than water provided by the Municipal Corporation. A low level of TDS in water sounds fine. However, drinking water must contain a suitable quantity of dissolved salts. Thus, it becomes very important to ensure an optimum TDS level in the water.

The optimum level of TDS in drinking water RO depends on several factors such as the location and quality of the source water, treatment processes used for purifying it and other environmental factors like temperature etc.

The acceptable limit set by WHO is 500 PPM (parts per million) while the US Environmental Protection Agency has set an upper limit of 500 PPM for its public water systems. In addition to this, most countries also have their own regulations regarding permissible limits for TDS levels in drinking water but these vary from country to country and from state to state within countries depending upon local conditions like geology, climate etc.

How to Reduce TDS in Water?

Drinking water with high levels of TDS causes lots of health issues like: mouth ulcers, stomach problems and so on. This article will discuss the methods to reduce TDS in drinking water at home.


Deionisation is a process that removes all of the ions in water and leaves pure, distilled water. To achieve this, the water passes through a membrane with positive and negative electrodes. The membrane allows for positive ions to detach themselves from the rest of the water molecules and move towards the native electrode. This process is most common in water heaters and geysers that treat hard water.


Distillation is simple but requires a setup using apparatus usually found in a Chemistry lab. Distillation involves boiling the water and collecting the steam in a separate chamber. The steam then condenses and returns to a liquid state so it can be collected again.

Reverse Osmosis

Water purity plays a crucial role in our daily lives. The higher the water purity level, the better it is for you and your family. And what better way to ensure pure water than to use an RO Water Purifier?

The TDS Test Strips are the most accurate and economical way to check the purity of your water. The TDS Test Strip Kit includes over 35 different individual test strips for measuring oxidation reduction potential, pH, conductivity, free chlorine and total chlorine, nitrate, nitrite, sodium, magnesium, calcium and total hardness. The kit also includes calibration solutions for all strips.

Why is it so important to keep track of TDS Levels?

High TDS levels indicate the presence of toxic chemicals and contaminants that can instantly affect the human throat. High TDS indicates the presence of hard water, so pair it up with a water softener that makes drinking water better for consumption if you’re using an RO filter.

A drinking water tds level chart tests the presence and concentration of minerals in water. The more minerals present in water, the higher the TDS level. High TDS levels may cause negative effects on the body if consumed over time, so an RO filter is great for removing these minerals from water before drinking it.

Sodium, calcium and magnesium are major components of hard water, which is prevalent in most parts of the world. To highlight how TDS levels affect our drinking water, I will list the different palatability quotients for each level.
