We are always concerned about the health and well-being of our loved ones. In the pursuit of this, we purchase various gadgets and devices to help make our lives more comfortable. One such product to look at, is the water purifier we use at home.
While we understand the importance of healthy drinking water, we sometimes make an impulsive decision while purchasing a water purifier.
The technology used in the water purifiers are broadly categorized into three types: RO, UV and RO+UV. To understand the technology better, read further.
While we hear the term RO a lot in advertisements and conversations, we might not fully be aware of the technology. RO stands for Reverse Osmosis. In an RO purifier, the water is pushed through a porous membrane, separating the dissolved salts and impurities from the water. The purified water then passes through the membrane, while the impure water with dissolved salts and contaminants is left behind. This impure water is later released from the water purifier as waste water.
Here’s when you should opt for an RO purifier:
Hard water which comes to your household consists of excessive physical, chemical, and microbiological contaminants. The Total Dissolved Salts (TDS) consist of calcium, magnesium, arsenic, iron, mercury, lead, fluoride and nitrates. These dissolved salts are present in high quantities exceeding the acceptable drinking water limits (500mg/litre). The presence of these dissolved salts result in harmful impacts on your body and affect the various functioning of the body too.
To reduce these salts from the water supplied in your locality and make it clean, one should opt for RO technology. This technology readily separates harmful chemicals and other impurities from your water, improves its taste by making it sweet.
Re-use RO Waste Water:
With every 4 litres of potable water, the RO purifier releases 3 litres of waste water. This waste water could be used in your day-to-day chores when mixed with normal water, listed below are the tips to re-use the RO purifier produced waste water:
- Mop the floor, as the salts in it will clean the floor effectively
- Wash utensils and vehicles you own
- Clean the toilets and window grills
UV purifiers use ultraviolet rays to de-contaminate the water and purify it to an optimum level. This technology treats waters in primarily three stages:
- The first step is suspension of particles dust, rust and mud upto 5 microns.
- The next stage is absorption of organic impurities, foul smell and taste, lead, pesticides and VOCs.
- The final stage is de-activation of bacteria, virus, protozoa including cyst and other micro-organisms.
It is a natural and chemical-free process which also retains the natural taste of water and all essential nutrients.
UV purifiers are better suited for homes with municipality water supplied from lakes and rivers.
Even though RO is considered to be a trendy technology, it might not be the right purification technology for your home, as it wastes a lot of water in the purification process. Moreover, if you receive municipal water/ sweet tasting water, and use an RO water purifier you lose out on essential minerals and natural salts present in the water.
