No one needs an introduction to water purifiers because practically every Indian house has one.
The quality of source water in India forces them to install a water purifier.
Though water purifiers work on various technologies, the Reverse Osmosis (RO as it is popularly known) is the most preferred and perhaps, the most effective, as well in Indian conditions.
No one can deny the utility of RO water purifiers, but this technology has its drawbacks.
It can be surprising that RO water purification results in tremendous water wastage.
Studies show that for producing one litre of RO purified water, these appliances waste a minimum of two litres of water.
In a country like India, it is a criminal wastage. Yes, there are other ways to use this water.
We shall not dwell into these aspects but discuss an innovative technology, Zero Water Wastage Technology in Kent RO water purifiers.
What is Zero Water Wastage Technology all about?
Does it mean that RO water purifiers will stop wasting water overnight? No, there is nothing of that sort.
RO water purifiers will continue to waste water, but this technology envisages better use of the wastewater for productive purposes.
Before we go into the intricacies of this technology, let us understand why RO water purifiers inherently waste a lot of water. It could be a burning question in your mind.
Generally, we use RO water purifiers where there is heavy TDS content in the source water.
Many places in India depend on river water or groundwater for their daily requirements. River water can contain industrial and human wastes. Industrial wastes comprise of heavy metal impurities like arsenic, antimony, lead, and others.
Similarly, groundwater contains large amounts of salts and TDS that make the water brackish and unfit for drinking.
The ideal solution is the use of best water purifier. RO water purifier works on the Reverse Osmosis technique to separate these heavy metals and TDS from water.
In the process of producing pure water, there is a massive rejection of water concentrated with TDS. It flows out through a separate outlet.
Zero Water Wastage Technology works on a unique technique where it retains the essential minerals and rejects the impurities alone. It further pumps the rejected water into the specific overhead tank using its pumping mechanism. It serves two purposes.
- There is limited wastage of water in RO purification.
- The rejected water gets diluted in the overhead tank and is supplied back through your taps for household purposes.
The latest Kent RO water purifiers work on this technology. Here are the benefits of zero water wastage technology.
- It reduces water wastage, the bane of all RO water purifiers.
- The rejected water is put to productive use like flushing toilets, watering plants, cleaning utensils, and so on.
Frequently Asked Questions
1. How is this technology beneficial when it still wastes water?
RO water purification will always result in water wastage. It is because the TDS is eliminated, not in a solid form but the form of a solution. The rejected water contains a high concentration of TDS. However, it recirculates the rejected water into the overhead tanks for other household purposes.
2. Do you need a special pump to send the rejected water into the overhead tank?
Generally, an additional pump is not required. Kent RO water purifiers employing this technique use a special inbuilt pump to send the water up to a maximum height of ten storeys. If your overhead tank is much higher, the pump will be ineffective. Under such circumstances, you can get the water pumped into the individual storage tanks that every flat usually has.
3. Does this entail that the overhead tank gets contaminated with more TDS?
One should look at the issue from a different angle. The overhead tank has a massive capacity. The amount of TDS water that goes from your RO water purifier is minuscule. It will not affect the water quality in any way. Moreover, with freshwater input into the tank, the TDS water gets further diluted to make any difference.
4. Should I now invest in a new RO water purifier with Zero Water Wastage Technology?
No, you can use your existing Kent RO water purifier and install an upgrade kit to get the benefit.
5. Can I use this technology on commercial RO water purifiers?
Yes, it is possible to use this technology on all Kent RO water purifiers, domestic and commercial.
6. Do all new Kent RO water purifiers come equipped with Zero Water Wastage Technology?
Yes, all the new Kent RO water purifiers come with Zero Water Wastage Technology. You do not have to install the upgrade kit in such machines.
7. Should I use a separate tank for collecting the rejected water?
No, it is not necessary. The rejected water can directly go into the common overhead tank of the building. However, you should sort out the internal issues with the building association officials before installing this technology.
8. How can we say that this technology reduces water wastage?
This technology reduces water wastage by recirculating the rejected water for productive purposes. If it were not for this technology, the rejected water would have gone down the drain.
