The Hidden Cost of RO Purification
Reverse osmosis is one of the most effective ways to purify drinking water, but by design it cannot turn all of the incoming water into drinking water.
Two streams, not one
An RO membrane holds back dissolved salts and impurities. Those have to be flushed away, so every RO purifier splits the incoming water into purified water and a concentrated reject stream.
Output and wastewater are linked
For the same amount of water entering the purifier, the more that comes out as purified water, the less goes down the drain, and the reverse.
It adds up at home
A household purifier runs every day. Over months, the reject stream becomes a real volume of water, which matters most in homes that depend on borewells, tankers or a limited municipal supply.
Ask about recovery before you buy
When comparing purifiers, ask for the water-recovery figure and the conditions it was measured under, and weigh it alongside purification needs, maintenance and running cost.
More of Every Litre Reaches Your Glass
DELTA follows the same basic path as any RO purifier. What sets it apart is how the water is shared out at the end: it is engineered so that up to 60% of the incoming water leaves as purified water.
Step 1
Incoming water
Water from your tap, borewell or tank enters the purifier.
Step 2
RO purification
Water is pushed through the RO membrane, which lets water pass and holds back dissolved salts and impurities.
Step 3 · Output
Purified water
The water that passes through the membrane goes to storage and your dispenser. With DELTA, up to 60% of the incoming water.*
Step 3 · Concentrate
Reject water
The rest carries the held-back impurities away to the drain. Higher recovery means a smaller share ends up here.
Water recovery = purified water out ÷ incoming water in
At 60% recovery, for every 10 litres entering the purifier
*Water recovery is the share of incoming water delivered as purified water. Actual recovery depends on inlet-water quality (TDS), water pressure, temperature, membrane condition and operating conditions, so it varies between installations.
Every Drop Matters. Recover More with Himajal Delta.
Advanced RO technology engineered to achieve up to 60% water recovery, helping reduce reject water and make better use of every drop.*

HIMAJAL DELTA · Make every drop count.
Better water recovery
Engineered so up to 60% of the water entering the purifier comes out as purified drinking water.*
Reduced reject water discharge
A higher recovery means a smaller share of the incoming water is sent to the drain.
More efficient use of incoming water
Less water needs to enter the purifier for the same glass of purified water.
How Much Water Could You Save?
Purified water you need per day
Compare with a conventional RO at (example rate)
Conventional RO
Example: 25% recovery
- Incoming water
- 80 L/day

- 20 L/day
- Reject water
- 60 L/day
HIMAJAL DELTA
Up to 60% recovery*
- Incoming water
- 33.3 L/day
- Purified water

- Reject water
- 13.3 L/day
Potential water savings
46.7 L/day
≈ 1,400 L a month · 17,033.3 L a year less incoming water for the same 20 L of purified water.
That is 78% less reject water than the 25% example, at DELTA's maximum 60% recovery.
Actual water recovery depends on feed water quality, operating pressure, temperature, and system configuration. Up to 60% recovery represents maximum achievable performance under specified operating conditions.
Conventional RO figures use the example rate you select and are for illustration only. They are not measured or industry-average values. Formula: incoming water = purified water ÷ recovery rate; reject water = incoming − purified.
Experience the Benefits of Alkaline Water
pH tells you how acidic or alkaline water is, on a scale from 0 to 14. Pure water sits at 7, which is neutral. Alkaline water sits a little above 7. DELTA purifies your water through RO and gives you mildly alkaline drinking water, with a taste many families prefer.
Balanced pH
Mildly alkaline drinking water, rather than the flat taste plain RO water can have.
Smooth, Fresh Taste
A light, refreshing taste that makes every glass more enjoyable.
Easier Daily Hydration
Water that tastes good is easier to drink enough of, all through the day.
Purified First
Every glass is RO-purified, so the water is clean as well as alkaline.
For the Whole Family
Everyday alkaline drinking water for everyone at home, from one purifier.
No Bottles to Buy
Alkaline water straight from your kitchen — no need for packaged alkaline water.
Alkaline water is drinking water. It is not a medicine and is not intended to diagnose, treat or prevent any medical condition.

Frequently Asked Questions
Recovery is the share of the water entering the purifier that comes out as purified water. At 60% recovery, for every 10 litres that enter, about 6 litres come out as purified water and the rest leaves through the reject line. DELTA is engineered to reach up to 60% under suitable operating conditions.
