Water TDS Level for Drinking Purpose - How RO purifier help in reducing it?
TDS (Total Dissolved Solids), is another name for the variety of substances that make up water, particularly drinking water. TDS may include both organic and inorganic components. That can be anything from molecules to small granules in size.
All dissolved inorganic and organic substances are measured as total dissolved solids (TDS) in water. Among the organic components that can be found in drinking water are algae, bacteria, insecticides, and disinfectants. Drinking water may contain impurities such as lead, arsenic, calcium, salt, chlorine, and other inorganic compounds. In this following discussion, we will be highlighting what the TDS level is recommended for drinking, how RO purifier work to maintain the correct TDS level and why should drinking water be purified.
TDS is not water hardness! How TDS differs from hardness?
Water can contain high TDS concentrations without being labeled as hard, proving that hardness and TDS are not the same things. The quantity of calcium and magnesium salts in water, typically in the form of bicarbonates or may be sulfates, is what is explicitly referred to as "hardness." As opposed to calcium and magnesium, TDS measures the sum of all mineral components.
The ability of the water to react with soap can sometimes be used to determine how hard it is. To make a lather with hard water, much more soap is needed. Measuring the calcium and magnesium content is the most typical approach to determining the hardness of water.
Water hardness has shown to have a detrimental influence on pipes, tiles, and other home furnishings as well as to dry out the skin and hair. WHO advises drinking only pure water with a hardness of 60 mg/L to 120 mg/L.
Purpose of TDS Level in Drinking Water
TDS levels in water can be high or low for a variety of reasons, therefore it's crucial to know what each element is in areas where the levels are too high or too low for everyday consumption. Sewage, urban runoff, industrial wastewater, water treatment chemicals, chemical fertilisers used in gardens, and plumbing are some of the sources of TDS in drinking water.
Although high TDS levels in drinking water are not harmful to health, they do give the water a salty, bitter, or brackish flavour. Two minerals that are frequently present in TDS are calcium and magnesium which can also result in hard water, the development of the scale, and discolouration.
Examples of water sources with high and low TDS
TDS levels are often lower in waters derived from icebergs or rain than those in springs or artesian wells since these waters haven't naturally drained through the ground.
This is a result of three primary elements:
- How many minerals are present?
- How readily do they dissolve in water?
- How long water is in contact with the mineral source in the earth?
Effects of TDS Level
TDS is expressed in parts per million (PPM) (ppm). Between 50 to 300 ppm is the appropriate TDS range for water. Technical repercussions from high TDS levels can also affect the flavour and odour of drinking water. Drinking water TDS concentrations of 1000 ppm or above are considered too high for human consumption, as indicated earlier.
High TDS level in drinking water brings on a lot of health hazards. Various researchers have said that drinking water with a high TDS level regularly can result in major health risks like diarrhea and typhoid. High concentrations of dissolved calcium and magnesium salts can cause scale to grow in pipes and build up, which shortens the life of appliances. High TDS levels in water can result in several issues, including fading of clothing colours, wet spots on utensils, and build-up in sinks and faucets.
It is significant to remember that some of the dissolved minerals in water are advantageous to human health, hence it is also not recommended to have very low or zero TDS. Water with a very low TDS content has a bland flavour. Although there is no set lower limit, TDS levels of at least 80 ppm are regarded as appropriate.
Pure water is colourless, odorless , and tasteless, but any additives can change those qualities. It is crucial to understand the TDS content of water. TDS level was referred to as a measure of water taste in numerous research. High TDS levels increase water hardness, contributing to the taste of the water being disagreeable. Because of this, checking the drinking water TDS level before consuming it is crucial.
Consequences of excessive TDS:
You will encounter particular issues with a high TDS level, such as the following:
- Water with an unpleasant flavour.
- Mild signs, such as nausea and lightheadedness.
- Mineral buildup in the pipes will cause the faucets in your kitchen sink and bathroom to tarnish.
- Inadequate access to clean water.
How is TDS measured?
You can use a TDS metre, which evaluates the conductivity of water, to determine the total dissolved solids at home. Water's conductivity is a measure of how well it conducts electricity. Mineral-free water has a TDS of 0 and does not conduct electricity. Water conducts electricity more readily the more minerals are present in it. The conductivity data can then be translated into milligrams of minerals per litre equivalent when measured at a standard 25°C temperature. The majority of handheld metres will provide your results in terms of conductivity or TDS.
Weighing the minerals that remain after the water has been evaporated from the sample is the standard procedure for determining TDS in laboratories. To further evaporate water from the mineral residue, the liquid is evaporated at 104°C/219°F and the residual dry matter is then heated in an oven at 180°C/356°F. Both the TDS number and the milligrams of substance that remain per litre are weighed. Despite the possibility of solids loss, 180°C is a suitable compromise between minimising dry material loss and completely removing water.
What is the perfect solution to reduce TDS in water?
Today, a water purifier with TDS controller is a basic requirement for any home. Drinking water has a significant impact on our health. When buying a water purifier RO, there are a few important factors to take into account. Now let’s come to the factor of what purification system can effectively reduce TDS level of water. Reverse Osmosis or RO is a traditional and effective method of purifying contamination and dissolved solids from water.
Reverse osmosis (RO) is a membrane-based filtration technique that applies pressure to a solution while on a particular side of a selective membrane. You must first understand the naturally occurring process of osmosis to comprehend the goal and mechanics of reverse osmosis. Osmosis is a phenomenon that happens naturally and is one of the most important natural processes.
How do water purifiers with TDS controller work?
Water purifiers with TDS (Total Dissolved Solids) controllers are designed to optimize the mineral content in purified water. TDS represents the total concentration of dissolved substances in water, including minerals, salts, and other impurities. Here's how water purifiers with TDS controllers work:
Monitoring TDS Levels:
Water purifiers with TDS controller constantly monitor the TDS levels in the incoming water. TDS is measured in parts per million (ppm).
Adjusting Mineral Retention:
Based on the TDS readings, the TDS controller adjusts the mineral retention during the purification process. It allows essential minerals to pass through while removing harmful contaminants.
Maintaining Optimal Taste and Nutrition:
By retaining essential minerals like calcium and magnesium, TDS controllers contribute to the improved taste of water. Moreover, these minerals are vital for health, and their retention ensures that the purified water remains nutritionally balanced.
Customizing TDS Levels:
Some water purifiers with TDS controllers provide users with the flexibility to customize the TDS levels in the purified water. This feature is beneficial for individuals who prefer water with specific mineral concentrations.
Enhancing Hydration:
Optimal mineral content in water can enhance hydration and contribute to overall well-being. Water purifiers with TDS controllers strike a balance by removing harmful impurities while preserving essential minerals.
Indicator for Filter Replacement:
TDS controllers may also serve as indicators for filter replacement. A significant increase in TDS levels could suggest that the purification components need replacement.
Adapting to Water Source Variability:
These purifiers are particularly useful in areas where the TDS levels in the water source can vary. By adapting to these variations, the purifier ensures consistent water quality.
RO and UV Technologies:
Water purifiers with TDS controllers commonly found in Reverse Osmosis (RO) water purifiers are effective in removing a wide range of contaminants. Some purifiers also integrate Ultraviolet (UV) technology for additional disinfection.
Hence, water purifiers with TDS controllers offer a comprehensive solution by maintaining the essential mineral content in purified water. They provide not only safe and clean drinking water but also water that is enriched with beneficial minerals for better taste and overall health.
How do RO filters' effectively features help in reducing drinking water TDS levels?
Through a membrane, the solvent travels naturally through the typical osmosis process from a High Water Potential to a Low Water Potential. Osmotic pressure is produced when a pure solvent is moved across a membrane to balance the concentrations of solutes on each side. Reverse osmosis is the process of using external pressure to change a pure solvent's direction of flow. The procedure is comparable to previous uses of membrane technology. However, there are significant variations between filtering and reverse osmosis. Since filtration is the crucial method of particle removal in membrane filtration, the process can potentially accomplish 100% exclusion of dissolved salts and other harmful particles, regardless of any operational factors.
