What Is TDS In A Water Purifier? How to check it?

What Is TDS In A Water Purifier

Water Purifiers have made drinking every glass of water that is pure much easier. Since we all know water is the most critical source of life, we do not in any way want to mess it up.

But we humans couldn’t keep up with nature and somehow landed ourselves in a situation where we polluted every natural resource we had. Unluckily water isn’t an exception.

Nowadays, the water that we get contains innumerable impurities, chemicals, and contaminants that can risk our lives. And this made it necessary for every household to invest in a water purifier.

Since the time water purifiers came, there was no turning back. It made water clean and, in fact, healthy to drink than it ever was.

But the confusion was, what made water purified through purifier drinkable? Well, it was nothing but a device that could balance the water TDS.

Water needs to have accurate TDS to make it drinkable, and that’s all the purifier does. This makes it necessary to understand what water TDS is and how you can control it.

 

What is the TDS in water?

Basically, TDS means nothing but the Total Dissolved Solids in drinking water. It represents the total concentration of dissolved substances in water that are not always safe to consume for humans at a certain level.

The water TDS has inorganic sals and some amount of organic matter as well. They could be good and bad as well.

The common inorganic salts often found in water are sodium, calcium, potassium, and magnesium. All of these salts are cations.

And the carbonates, nitrates, bicarbonates, chlorides, and sulfates are all anions. If you look into your science textbook, you will remember that cations are all positively changed while anions are all negatively charged.

Now we surely get the technicalities of what is water TDS, but where does this call get into the water. So here’s what you should know to realize how unsafe this is.

 

How do cations and anions get dissolved in water?

Surprising as it may be, but we humans are not entirely responsible for cations and anions found in water.

These minerals get dissolved in water both through natural and human activities.

For example, if we consider spring water, we might simply fall in love with it. But we still can’t drink it, even though it is natural. This is because spring water has a higher level of dissolved solids.

It flows through the rock after rock which has higher salt content. This leads to a higher amount of calcium and magnesium in the water, which is not at all fit for human consumption.

Hence it has higher dissolved solids. And same happens through human activities as well. From agricultural activities to urbanized ones, we somehow end up polluting water.

This way, both natural and human activities lead to dissolving cations and anions into the water, making it unfit for direct human consumption.

However, you will be surprised that not all cations and anions are harmful, and you should not drink water with zero TDS as well. Water TDS is equally essential, and here’s what you should know.

 

Why is TDS crucial in drinking water?

As we mentioned above, TDS in water is dissolved through natural and human activities; it would be bad to eliminate it completely.

Water is a universal solvent and can easily get mixed with all types of solvents quickly. It also changes the taste of water, making it sometimes bitter, salty, and also sweet.

But humans do need calcium and magnesium in some amounts to survive. If we completely eliminate water TDS, we might make it more harmful than we can think of it in a longer duration.

By now we already know that not all TDS in water are dangerous for human consumption.

This makes it essential to drink water with accurate TDS in order to be healthy. Water TDS has both consumable and unsafe levels, which will help you understand water TDS better than you ever did.

 

What is the accurate water TDS level fit for human consumption?

The range of water TDS matters the most, no matter what water purifier you are using.

According to WHO, the accepted water TDS level is 300 parts per million.

Water with TDS around 300ppm is hence safe for human consumption. Higher TDS than this, however, may not be that dangerous for humans but can taste bitter or salty.

This is because water with higher TDS than 300ppm will have a higher level of minerals like sodium, potassium, and other such similar solvents mentioned above.

Any water with higher TDS than 300ppm will require extra Reverse Osmosis filtering that is RO purifier with additional purification to make it palatable.

Hence, most of the RO purifiers have a special membrane that easily holds back a more significant amount of dissolved solvents, eventually giving you purified drinkable water.

The water will likely taste good and won’t even cause any severe health issues in the future.

This was about the purified water level. But when the water TDS goes far beyond 300ppm, it can become completely unsafe, and here’s what you should know.

 

What water TDS makes water unsafe for drinking?

We always want to make sure we drink water that will improve our health in a lot many ways and not damage it.

And so WHO has given unsafe water TDS levels for humans that you all should know about.

Basically, any water, natural or purified, indicating a TDS level beyond 1000ppm is unsafe for human consumption. And water TDS above 1200 is completely unacceptable; hence people should not consume it at all.

Water with such higher TDS is often recognizable due to vast differences in water color, odor, and even a weird sense of taste.

Apart from this issue, a high level of TDS can also lead to excessive scaling in water pipes, boilers, heathers, and other household appliances.

With all the information that you have by now regarding the TDS level in your drinking water, it evident that you are curious to know how you can really check its level.

So here we are with the easiest ways to check the water level and make sure you are drinking healthy water for a happy life.

 

How to Check TDS Water Level at Home?

Since we are all caught up with multiple health issues, it is mandatory to know your water  TDS level is accurate and not dangerous for you or your family for a longer duration.

There are several methods to check TDS levels in the water. Some are easy, and others might take up hours. But we made sure to get you the easiest tricks below. Have a look at them all and find out the TDS level of your water.

Digital TDS meter to Rescue

Digital TDS meter to Rescue

We are all busy with multiple tasks throughout the day and all thanks to technology for making our lives simpler.

Checking water TDS isn’t an exception as we have handy technology for that as well.

A digital TDS meter is one of the easiest ways to measure the TDS level in the water.

The best part with the Digital TDS meter you won’t need to take the reading or even need to calculate any further to check the exact value of the TDS level.

You get the result within seconds on the device, and you can rest assured it is accurate as well.

So here’s how you can check TDS level using a digital TDS meter.

The method to use a digital TDS meter includes two steps. You will have to check the water temperature before checking the TDS level using a digital TDS meter.

Step: 1: Check water Temperature

Switch on the digital TDS meter in order to check the water temperature. You will have a temperature button for doing this on the TDS meter.

Simply press the “TEMP” button, and you will get the water temperature reading in degrees celsius.

So now you know the water temperature, and next you have to check is the TDS level. But before that, get back to TDS mode by simply pressing the “TEMP” button again.

Step: 2 Check water TDS

So the next is to check water TDS, as now you know the water temperature. You should know that you won’t be able to check the TDS of too hot or too cold water.

Hence, it is mandatory to have water at room temperature to check the water TDS. If you have, here’s what you should do.

Remove the protective cap, and switch on the meter. Immerse the digital meter into the water up to the level indicated on the meter. It will usually be around two inches.

Gently stir the TDS meter to remove all the air bubbles and wait for few seconds to get the reading. Once the water stabilizes, long-press the hold button and remove it from the water container.

Shake it a bit to remove the excess water, and check the reading. Put the cap once done.

That’s all; you now know the exact TDS of the water you are using at your home, work, etc.

There are chances your digital meter might show the X10 symbol. In such case, you will have to multiply the reading by 10 to get the exact TDS value of water you are r will be consuming.

Secondly, not all digital TDS meters are waterproof. So make sure you don’t dip the digital meter above a specific level indicated on the meter. Also, make sure you store it away from direct sunlight.

In case this seems a lot to deal with, here’s the second way you should try to check the water TDS.

 

Electrical Conductivity Meter

Electrical Conductivity Meter

Since we already know what all the water with higher TDS includes, having a gadget that detects it accurately is extremely important.

Other than a digital TDS meter, electrical conductivity meter is the second way to detect water TDS accurately. Here are the few steps you should follow while using an electrical conductivity meter to see the water TDS.

Things you will need

  • Clean dust-free sterilized glass beaker
  • Charged electrical conductivity meter
  • Water with temperature around 250C.

An electrical conductivity meter can often release electric current into the water while measuring TDS. Make sure you have water in a separate beaker and not use the regular usage water tank for safety precautions.

So let’s begin with the process.

Place the beaker on the flat water surface, and switch on the electrical conductivity meter to check the water TDS.

Immerse the measuring lead of the conductivity meter into the water to a suggested level.

Note down the reading you see on the meter immediately. It will take a bit longer, around 4 to 5 minutes, to get an accurate reading.

The reading you will get will be in the Micro Simens unit. Pure water most often has 0 micro simens.

Thus, you should know that the measurement will largely depend on the water quality you are measuring.

However, you should know that this method requires some mathematics to calculate the accurate water TDS.

Therefore the next step is to put the reading that you get into this formula.

TDS (in mg/litre) = KE (Co-relation factor) X EC (Conductivity)

And the answer after this calculation is the exact TDS value of the water. This might be a bit longer compared to the digital TDS water meter, but you can check accurate water TDS with either of the methods.

You by now know both the methods that are easy and convenient to check the water TDS.

What we recommend is to check the water TDS before you buy a new water purifier. This is because the TDS water level will help you pick the right water purifier, eventually making it easier to consume healthy drinkable water.

All of the TDS found in water are hazardous to health, and you should be extra careful with it. So to cut down the water TDS intake, check your water’s TDS level now and get a purifier that purifies it to make water healthy and drinkable.

 

FAQS about Water TDS

Is water with low TDS drinkable?

With all the studies and research done till now regarding the consumption of water with low TDS, it is confirmed that there are no severe side effects of drinking it.

There are no harmful effects to the human body when consumed with low TDS water. However, you can experience low immunity in a longer duration and bad bone health.

This is because the water lacks calcium and other essential minerals as well. Hence can be an issue for a longer duration if you do not have a better calcium intake.

 

What is the maximum TDS level found in drinkable water?

According to the research done by EPA secondary drinking water regulations, the maximum TDS level of your drinking water should be 500ppm to make it healthy.

However, water up 100- TDS is still safe, but anything beyond that is hazardous to health.

 

Can boiling water reduce TDS?

No, that is not really possible. No matter how long you boil your water before consuming it, it does not remove heavy metals that are dissolved in the water.

Since water can contain a variety of toxic solvents like mercury, lead, arsenic, fluoride, etc. and hence having a water purifier is essential.

 

Conclusion

We know that’s a whole lot of information to grasp, but we also know it’s for our own good.

Staying healthy by drinking a healthy glass of water 8 to 9 times a day can not only increase your life expectancy but can also make your skiing glowing.

The benefits of drinking pure water are endless, and we know you exactly know how pure it should be.

But knowing accurate water TDS is just not enough. Getting a good water purifier is equally essential, especially the one that meets all the health needs.

Hope you get that once you know the TDS of your water.
