5 Best RO Water Purifier with less water wastage in India 2024

It is not unreasonable that a reverse osmosis water purifier cleans dirty water. Did you know that producing 1 litre of pure water, wastes 3 litres of impure water? If there are no water shortages, disposing of waste exceeding 3 litres is acceptable. For individuals with limited access to water in their households, it is not beneficial to waste additional water. But don’t worry; many good water purifier brands in the market claim to save 87% of water. But reverse osmosis water purifier is indeed unable to keep 100% water. After consulting with industry experts and reviewing online product ratings and customer feedback, our team has compiled a list of the top RO water purifier with less water wastage in India.

Frequently Asked Questions

Which water filter wastes less water?

Water filter type, brand, usage, and other factors can affect water waste. However, Reverse Osmosis (RO), Gravity, and Faucet filters are the most common water filters. RO filters remove contaminants well but waste a lot of water. RO systems waste 3–5 gallons per gallon filtered. Poorly designed systems can have a 24:1 ratio, depending on water pressure and temperature. Instead, Gravity filters force water through the filter. They’re greener because they don’t use electricity or wastewater.

Gravity and tap filters waste less Water than Reverse Osmosis systems. However, RO systems may filter contaminants better.

How can we save waste water from RO?

Reverse osmosis (RO) systems produce a significant amount of wastewater—up to 4 times the amount of purified water. This is because only a fraction of the contaminated feed water passes through the RO membrane, while the rest is discharged as brine. However, we can reduce this wastage through several approaches:

  1. Reuse RO wastewater for applications like lawn irrigation, toilet flushing or industrial cooling that can tolerate higher dissolved solids. This also reclaims the 70-80% contaminants that were removed. Simple filtration can be added.
  2. Send wastewater through a second-pass RO to re-purify and recycle up to 90% via multi-stage configurations, minimizing losses.
  3. Use RO judiciously – restrict to drinking/cooking needs. Use simpler filtration or tap water for other requirements to lower overall RO usage and wastage generation.
  4. Opt for energy-efficient RO systems with high pump, membrane and energy recovery efficiencies for higher recovery rates (~50%).

How much water is wasted in RO filters?

RO uses a semi-permeable membrane to filter water. RO systems purify water but produce a lot of waste.

RO system efficiency determines water waste. A typical ratio is 3:1 or 4:1. Each gallon of purified water wastes three to four gallons.

With permeate pumps or other efficiency-boosting technologies, some RO systems can have a waste-to-purified water ratio of 2:1 or even 1:1. These systems are more expensive and rarer than standard RO systems with higher waste-to-purified water ratios.

An RO system’s “wasted” water can be used. It’s usually flushed, but it can be collected and used to water plants or flush toilets. The RO system’s wastewater contains more impurities than the drinking water, but it’s safe.

RO systems waste water, which can be a problem in water-scarce areas. In arid regions with scarce fresh water, these systems’ wastewater can cause water stress.
