communities worldwide

Understanding TDS in Water: Why RO Filtration Matters?

If you’ve ever checked your water’s quality, you may have come across the term TDS (Total Dissolved Solids). But what exactly is TDS, and why does it matter? Let’s break it down and explore why reverse osmosis (RO) filtration is the best way to manage TDS levels.

TDS refers to the total amount of dissolved substances in water, including minerals like calcium, magnesium, and potassium; salts such as sodium and chloride; metals like lead, arsenic, and iron; and various chemicals, including nitrates and sulfates. While some minerals in water are beneficial, high TDS levels can indicate contamination and poor water quality.

High TDS can cause several problems. It can result in bad taste and odor, making water taste salty, metallic, or bitter. Elevated levels of heavy metals and chemicals can pose potential health risks. Hard water with high TDS can lead to scaling and buildup in pipes and appliances, causing inefficiencies and damage. Additionally, high TDS water affects the taste of food and can leave streaks or spots on dishes, making cooking and cleaning less effective.

RO filtration is the most effective method to lower TDS. RO systems work by forcing water through a semipermeable membrane that removes up to 99% of dissolved solids, including harmful contaminants. This process significantly reduces TDS levels, improving overall water quality.

The ideal TDS level varies depending on the intended use of the water. Water with less than 50 ppm is considered ultra-pure and is typically used in laboratories. A range of 50-150 ppm is ideal for drinking water, while 150-300 ppm is acceptable but may require additional filtration. Water with a TDS level above 300 ppm may indicate potential contamination and poor taste.

Monitoring TDS levels is essential for ensuring clean and safe drinking water. Reverse osmosis filtration is the most effective way to reduce excess TDS and improve water quality. If you want better-tasting, healthier water, an RO system is the best investment for your home.
