A Comprehensive Guide to Total Dissolved Solids (TDS) in Drinking Water

As experts in water filtration and purification with years of experience and in-depth knowledge, we are well-positioned to guide you through the complexities of water quality. One key aspect of water quality that we frequently encounter in our work is Total Dissolved Solids or TDS. This guide will provide you with a detailed understanding of TDS in drinking water, its implications, and effective solutions to manage it.

Understanding Total Dissolved Solids (TDS)

Total Dissolved Solids, often abbreviated as TDS, refers to the combined content of all inorganic and organic substances contained in a liquid in molecular, ionized, or micro-granular suspended forms. In simpler terms, TDS is essentially the measure of various mineral salts, metals, and other particles dissolved in water. These can range from calcium, magnesium, and potassium to nitrates, phosphates, and trace amounts of heavy metals.

The sources of these dissolved solids can be natural or anthropogenic. Natural sources include the leaching of minerals from rocks and soils, while anthropogenic sources can include urban runoff, sewage, industrial wastewater, and chemicals used in water treatment processes.

TDS in Water’s Impact on Taste and Safety

The TDS in water has a profound impact on its taste and appearance. Water with low TDS tends to taste flat because it lacks the minerals that give water its crisp taste. Conversely, drinking water with TDS levels higher than normal may have a strong, salty, or even bitter taste. The appearance of water can also be affected; high TDS levels can make water appear cloudy or coloured.

Beyond taste and appearance, high levels of TDS can pose safety concerns. While most dissolved solids are generally harmless at low levels, high concentrations can lead to health problems. Certain dissolved solids, such as lead or copper, are harmful to health even at low concentrations.

Acceptable TDS Levels in Drinking Water

The World Health Organisation (WHO) suggests that the TDS level in drinking water should be below 300 mg/L for excellent water. Whilst specific countries may differ slightly on the exact amount, they generally agree on guidelines around this level.

How to Reduce TDS in Water

If you’re dealing with high TDS levels in your water, there are several effective solutions available. One of the most effective ways to reduce TDS is to use a TDS water filter. These filters work by using a process known as reverse osmosis, which involves forcing water through a semi-permeable membrane to remove impurities.

Besides using a water filter, you can also consider alternative water sources, such as bottled water or water delivery services. However, these options can be more expensive and less environmentally friendly than using a water filter.

Though these methods can be effective, they’re generally far more resource-demanding than alternatives and tend to be overkill for countries with relatively safe water. This is why at Billi, we offer a range of high-quality water filters that are designed to effectively reduce common sediments and other nasties in your water, ensuring you have access to clean, safe, and tasty water at all times.

Prioritising Water Quality for Health
