How To Use Ro Waste Water

One major drawback of using RO water purifiers is that you have to deal with a big amount of wastewater. As per various studies, RO purifiers are only capable of providing 20-25% clean water out of all the intake, rest is wastewater. So, the question that arises here is, what’s the reason behind the production of so much wastewater? To know about that, you need to learn about its working.

In simple words, RO purifiers use a membrane to filter out impurities. So, to clean up the membrane on its own, RO purifiers use some extra water, and eventually, that’s a total waste.

So, we have been thinking around this problem and found some pretty cool solutions as well. No, there’s no way we can cut down the wastage, but reusing the wastewater can also be a practical solution. Hence, this article is going to be all about this, if you’re interested to know how you can reuse the RO wastewater, sit tight, and enjoy thoroughly reading this article.

Why Reuse RO Waste Water?

Our RO purifiers do provide us clean and ready-to-drink water, and are quite economical as well since the maintenance is pretty less. But, when it comes to being eco-friendly, this is where RO purifiers fail to impress us.

As we have already mentioned, almost 3/4th percentage of water comes out as wastewater from an RO, finding a solution for it seems very necessary. Some people might be wondering if it’s okay to re-filter the wastewater, that’s totally not advisable as an RO purifier only throws out waste that it cannot deal with.

However, if we see the problem from a different aspect, the wastewater is just not suitable for drinking, right? But, look around you, there are so many places where you can make use of this wastewater, until and unless the TDS level is satisfactory. So, if we all start to reuse the RO wastewater, this water wasting machine of ours can ironically help us save a good amount of water instead. Want to know how? Let’s discuss.

Easy Ways to Reuse RO Reject Water

Use the wastewater in Air Coolers

As most Air Coolers have a tank capacity of around 30-50 Litres on average, that’s similar to the amount of wastewater that an RO water purifier produces in a day. So, it is quite a practical option to extend and connect the wastewater pipe to the Air Cooler and enjoy cool breezes during the summers.

Wastewater can be used for washing your Car

A vast number of people in India prefer to wash their cars on their own at home. But, practically thinking, if we use the wastewater to wash the cars, a lot of good water can be saved regularly. Since cars show no bad reactions to the chemicals present in wastewater, you can clean your car without any worries.

Watering Plants with wastewater

Yes, watering the plants can be another use of wastewater, but you have to keep in mind certain things. As you know, wastewater is contaminated with impurities and chemicals, it is better to check for the TDS levels first because wastewater with high sodium concentration can be harmful to the plants. Otherwise, if the TDS level is below 2000, you can water your plants and take care of your home garden using wastewater.

Washing Kitchen Utensils

In most homes, RO’s are places or mounted near the kitchen sink, so the closest place where you can use the RO wastewater is the sink itself. Yes, we don’t see any complication washing kitchen utensils using wastewater. Hence, we are pretty sure that you would love the idea too.

Mopping the Floor

Well, nobody checks the water quality before mopping the floor, right? All we need to mop the floor is some dirtless water. And, that’s exactly what your RO water purifier provides you with. So, better utilize that wastewater to clean your home instead of wasting it by letting it flow in the sink.

Wastewater can be used for Laundry

Another handy use of the RO wastewater can be in our washing machines. No matter how convenient using washing machines are, the amount of water wasted in the process is massive. If we cannot eliminate the wastage, at least we can try to waste less by reusing the RO reject water for washing our dirty clothes.

Things to Keep in Mind Before Using the RO Waste Water

You can’t just collect all the wastewater and start using it for other purposes. Why? Because this water is coming out from a water purifier, so you should know that it is full of impurities, and chemicals. It is advisable to check the TDS level of water before reusing it in any other area.

For instance, RO water removes hardness from water, thus, the wastewater must have a high amount of hardness-causing elements which eventually rises up the TDS levels. Let’s say you want to water your plants using the wastewater, but if the TDS level is high, it can be because of a higher concentration of Sodium in it.

And, sodium is not at all friendly for the soil that can eventually harm the plants. However, if the TDS level of the wastewater is between 1500-2000, you can simply use it for whatever you want, except drinking!

How to Store the RO Waste Water?

There are several ways by which you can collect the RO wastewater where the easiest one is to put the reject water pipe into a bucket and collect the water. Although it might be the easiest method, it is not the most practical one since you will have to empty the bucket every time it gets full. In case you are looking for a smarter way to store water, then using a bigger storage tank connected with an extended wastewater pipe can be a good choice for you.

Well, this option has one drawback too, you will have to take water out of the tank with the help of a bucket or some other container. Don’t worry, we have a way to tackle it too. You can easily find a water pump in the market that we normally find in Air Coolers, and drop it into the tank, and supply power to it. This way, you can simply turn on a button and take out as much water as you want without putting any stress on your shoulders or back.
