How is Commercial RO Plant’s rejected water reused?
A Commercial RO plant is the most dependable water filtration system used in India. This is the only system that can successfully eliminate Total Dissolved Solids (TDS), chemicals, and other harmful contaminants, like lead, arsenic, etc.
It offers clean, safe drinking water but has one drawback: water waste.
Rejected water results from the RO membrane's removal of contaminated, impure water that is high in TDS. Although, this water should not be consumed or used for bathing, but there are many other uses for it.
Let’s learn some simple methods for reusing Commercial RO Plant’s rejected water!
1- Reuse rejected water by washing your car
The amount of water used in a single car wash can range from 14 to 75 liters. Daily car washing is needless and wasteful of water. If one has a RO plant at home or work, one can easily collect the used water in a tank or bucket and recycle it for car washing.
Car washing can be done safely with water that has a TDS of 1200 to 1500 ppm. If the waste water has a high TDS content, mixing it with tap water will dilute it. This ought to lower the TDS level.
2- Use wastewater again by watering plants
Watering plants with RO rejected wastewater can keep an indoor or terrace garden green. Because, public water often has a lower TDS level, this advice is especially helpful for city dwellers.
For 15 to 20 days, use the RO waste water to observe how it influences plant development. Each plant will respond to this alteration in a distinct way, making it evident which plants are reacting better to RO waste water.
For irrigation and gardening, TDS values up to 2100 ppm are acceptable. Additionally, the salt percentage should be less than 60%. High sodium content decreases soil porosity, which eventually impairs soil fertility.
3- Utilize wastewater again by cleaning utensils
Simply collect the RO rejected water in a bucket or tank, and keep the bucket for RO waste water collection near the kitchen sink, so you can use it conveniently while cleaning your utensils.
4- Reuse RO reject water by moping the floor
It's easy to use RO wastewater to mop the floor and it will save you tens of liters of pure water per day.
Dilute waste RO water with equal parts of tap water, if the TDS level in the wastewater is high, i.e., more than 2000 ppm. Use the RO waste water for floor sweeping on alternate days. As a result, there will be less chance of stains or salt deposits.
5- Reuse RO reject water for laundry
The RO waste water can be used for regular laundry, but be aware that some sensitive materials may not be safe for high TDS water. Most homes in India now have washing machines, but despite the time and labour they save, they also use a lot of water. To collect RO waste water and utilize it straight in a washing machine, one can construct an above water tank.
6- Reuse RO reject water by cleaning toilets
In contemporary households, toilet flushes are a major source of clean water waste. About 5 to 7 litres of potable water are flushed down the drain with each flush. One can efficiently cut down on this use of clean water by flushing toilets with RO waste water.
When starting out, keep an eye out for deterioration on porcelain surfaces in toilet seats. Regular cleaning with inexpensive toilet cleaners will help you prevent discoloration and salt build-up.
How can we assist?
All of these methods for reusing RO reject water can be very advantageous, but they can also take a lot of time and work. These seemingly insignificant variations can have a big effect on the ecosystem.
