Healthy water on earth is found in different forms and variations. For millennia, we depended on the water from glaciers which flows down in the form of rivers and streams for drinking and cooking water. That is the reason why the most affluent and prosperous civilizations have developed on river banks and around lakes. However, industrialization and environmental pollution has contaminated most, if not all, fresh water sources today. This has led to invention of technologies for water purification.
Reverse osmosis is the leading water purification technology in the world today. In this post, we are going to explain that how reverse osmosis is different than a carbon water filter.
How carbon filtration works:
The process of carbon filtration uses a set of sediments to remove contaminants by blocking them physically. In a carbon filtration process, pressure is used to force the water through a filter to treat it for chlorine taste, odour, dirt, sediment, rust, giardia, cryptosporidium, heavy metals, arsenic, and volatile organic compound removal.
We do not wish to undermine the effectiveness of this method as the output water is definitely cleaner than untreated water. But there are better technologies available these days for water filtration.
How reverse osmosis works:
Reverse osmosis is one of the landmark innovations in our quest against pollution. It provides the highest quality drinking and cooking water by removing more than 99 per cent of all impurities present in a water supply. RO purifiers can filter volatile organic compounds, pesticides, herbicides, heavy metals, endocrine disrupting chemicals as well as hormones and cysts.
Reverse osmosis water purifiers also use a carbon filter to remove chlorine and sediments before treating the water with osmotic push. An osmotic membrane with microscopic holes is used to push the water molecules to the other side. In this process, only the water molecules which are small enough can pass through, leaving all other contaminations behind. However, this process can also remove some taste enhancing minerals which are naturally present in the water. To compensate for that, modern RO purifiers from brands like Livpure come with mineralizer cartridges which add the suitable minerals and salt back into the purified water. Thus, the water you get is not only fresher and healthier, but it also tastes naturally good.
