Water quality is very important for our health, our daily activities, and the lifespan of our household appliances. A term often mentioned in connection with water quality is TDS. TDS stands for Total Dissolved Solids. In this guide, we will explain the TDS meaning, its significance, and the function of the Frizzlife RO system filter. All with the goal of helping you access clean and healthy water.
TDS meaning
Total dissolved solids (TDS) refers to all inorganic and organic substances that can dissolve in water. We measure TDS in parts per million (ppm). It includes various minerals, salts, metals, and organic substances. However, for water treatment systems that don't use reverse osmosis, the TDS value doesn't accurately reflect water quality. These purifiers don't remove minerals. For example, bottled water can also have a high TDS value. The TDS measurement is especially relevant for RO systems. It indicates how effectively contaminants are filtered out.
Types of dissolved solids
Dissolved solids can be divided into several categories:
1. Inorganic salts: Important minerals such as calcium, magnesium, potassium and sodium.
2. Organic matter: Formed by natural decomposition in water sources.
3. Trace metals: Come from natural sources or human activities.
These dissolved solids can significantly affect the taste and odor of the water, as well as its overall suitability for various uses.
Why should you measure total dissolved solids?
Measuring TDS can reveal a lot about water quality. While a high TDS level isn't necessarily harmful, it often indicates contaminants that can affect taste, health, and the maintenance of water-related systems in your home.
Taste and smell
The TDS level directly affects the taste and odor of water. An elevated TDS level often indicates the presence of minerals or impurities, which can result in a bitter or metallic taste and sometimes even a strong odor. Frizzlife reverse osmosis filters are designed to reduce the TDS level to maintain optimal taste, keeping your drinking water refreshing and free of unpleasant flavors.
Health
While not all dissolved solids are harmful, some can pose a health risk in high concentrations. A high TDS level often correlates with higher levels of chlorine, heavy metals, and other contaminants.Frizzlife reverse osmosis filters effectively reduce these contaminants, ensuring safer and cleaner water for drinking and cooking.
Filter maintenance
Water with high TDS levels can also affect the longevity and effectiveness of water filters. When TDS levels are high, filters have to work harder and can clog or wear out more quickly. Frizzlife reverse osmosis filters are built to last, and their advanced technology ensures low TDS levels, reducing strain on the filter and extending its lifespan.
Sanitary facilities and equipment
Water with high TDS levels can lead to mineral deposits in plumbing fixtures and appliances, shortening their lifespan and increasing maintenance needs. Minerals like calcium and magnesium contribute to limescale buildup, which can reduce the efficiency of water heaters, dishwashers, and other appliances. Using Frizzlife reverse osmosis filters can prevent limescale buildup, protect your home's water pipes and appliances, and save you money in the long run.
Cook
In the kitchen, TDS levels affect the taste and quality of food. Water with a high TDS level can alter the natural flavor of ingredients and impair the appearance and texture of food, especially when preparing teas, soups, and broths. Frizzlife reverse osmosis filters remove excess dissolved solids, allowing your food to retain its authentic flavor.
cleaning
Finally, water with high TDS levels can leave residue on dishes, surfaces, and clothing. Water with high mineral content doesn't rinse as well, leading to stains on glassware and a rough texture on clothes. Frizzlife reverse osmosis filters effectively reduce TDS levels, resulting in cleaner rinses and softer laundry.
Filter types that reduce the TDS value
Reducing TDS levels in water requires advanced filtration methods, as not all filters are capable of effectively removing dissolved solids. Below are the three main filter types that significantly reduce TDS levels in water:
Reverse osmosis systems (RO)
Reverse osmosis (RO) systems are among the most effective methods for reducing TDS. In reverse osmosis systems, water is forced through a semi-permeable membrane that traps dissolved solids, pollutants, and impurities, allowing only clean water molecules to pass through. The membrane typically removes up to 95-99% of dissolved solids, making it ideal for households requiring low-TDS drinking water.
distillation
Distillation is a process that mimics the natural water cycle. Water is boiled to produce steam, which then cools and condenses back into liquid form, leaving most of the dissolved solids and impurities behind. This process effectively reduces the TDS level because the impurities do not evaporate and remain in the boiling chamber.
Deionization
Deionization (DI) uses ion-exchange resins to remove charged particles from water. Positive and negative ions, such as calcium, magnesium, and sulfate, are replaced with hydrogen and hydroxyl ions, resulting in pure H₂O. Deionization effectively reduces TDS but is often used in conjunction with other filters because it does not remove bacteria or organic particles.
|
| Reverse osmosis systems (RO) | distillation |
| professionals | High efficiency in reducing TDS; removes various contaminants such as heavy metals, bacteria, and chemicals. | Removes virtually all dissolved solids and pathogens; requires minimal maintenance. |
| Disadvantages | Higher initial and maintenance costs; may waste some water during the filtration process. | Time- and energy-consuming; may have a bland taste due to mineral removal. |
Each of these methods offers unique benefits, depending on your specific TDS reduction and overall water quality needs. A combination of these systems, such as a reverse osmosis system with post-filtration, can provide even higher purity for those seeking near-zero TDS water.
The role of water filters in managing TDS
Water filters play an important role in managing the total dissolved solids (TDS) content of drinking water. By removing or reducing the concentration of these dissolved solids, filters contribute to improving water quality in several ways:
Reduction of harmful contaminants
High TDS levels can indicate the presence of contaminants such as heavy metals (e.g., lead, mercury), nitrates, and organic pollutants, which can lead to health risks over time. Modern water filters, particularly reverse osmosis (RO) and deionization systems, specifically remove these contaminants and lower TDS levels to safer levels. This not only improves the safety of drinking water but also ensures that daily water consumption does not contribute to potential health risks.
Improvement of taste and smell
Water with a high TDS level often has a pungent taste or odor, which can be attributed to minerals, metals, or chemicals present in the water. Carbon filters and reverse osmosis systems effectively remove chlorine, sulfur, and other elements that can impair the taste and odor of tap water. This results in fresher, more pleasant-tasting water that's safe to drink and use for cooking.
Protection of household appliances
Dissolved minerals in hard water can build up on the interior surfaces of pipes and appliances, causing scale buildup and reducing efficiency. Over time, this buildup can shorten the lifespan of water-dependent appliances such as water heaters, coffee makers, and dishwashers. Water softeners and reverse osmosis filters help reduce the minerals responsible for limescale buildup, protecting these appliances, minimizing repair costs, and improving overall household efficiency.
Improving water quality for health
Lowering TDS levels can significantly improve the quality of the water you drink daily. Water with high TDS levels can contain undesirable elements like sodium, sulfates, or metals, which can be detrimental to health, especially for people with certain medical conditions. Water filters that effectively control TDS levels ensure water is free of potentially harmful compounds, supporting overall health and well-being.
By addressing the problems associated with high TDS levels, water filters contribute to a healthier, safer, and more enjoyable water supply in the home.
How do you measure the TDS rejection rate?
Understanding the TDS rejection rate helps determine how effectively a water filtration system removes dissolved solids. Here's a simple guide to measuring it:
Measure the TDS value of the feed water (input water)
First, measure the TDS level of the feed water, i.e., the water entering the filtration system. You can use a TDS meter for this. Simply turn on the meter, immerse it in a sample of the incoming water, and record the reading.
Measure the TDS value of the permeate water (filtered water)
Next, measure the TDS level of the permeate water—the filtered or treated water coming out of the system. Using the same TDS meter, immerse it in the permeate water and record this reading as well.
Use the rejection rate formula
Using the two TDS readings, you can now calculate the TDS rejection rate. The formula is:
TDS rejection rate=【（TDS of feed water-TDS of permeate water ）/ TDS of feed water 】×100
This gives you the percentage of dissolved solids that the filter system removes from the water.
Example:
- TDS of tap water (feed water) = 300 ppm
- TDS of RO water (filtered water) = 15 ppm
Rejection rate=【(300-15)/300】×100=(285/300)×100≈0.95×100=95%
Interpret the results
A high rejection rate (typically 90% or higher) means the filtration system is very effective at removing TDS, while a lower rate may indicate that the filter needs maintenance or replacement. Regular rejection rate testing can help maintain optimal water quality.
