BUYING GUIDE FOR BEST WATER PURIFIER IN INDIA: BUYING GUIDE FOR BEST WATER PURIFIER IN INDIA Least to say, water that appears as visibly clean may contain several dissolved impurities in it including bacteria & viruses apart from salts & heavy metals with sand or mud. Undoubtedly, water pollution is a major concern & is growing at light speed these days in name of revolution. Specifically, modern & best water purifiers in India include technologies like Reverse Osmosis (RO), Ultraviolet light (UV) & Ultra Filter or Micro Filter that help widely in the purification of water from visible to invisible impurities. But a deeper context related to a few other aspects needs to be understood before making your selection. Undoubtedly, this buying guide helps you navigate through them comprehensively. SOURCE OF WATER: Well, it has to be due noted that not all the water that is made available is suitable for human consumption & drinking purpose. As a result, it becomes necessary for us to understand the sources of water that are available. Broadly water can be Surface water or Groundwater. Basically, surface water is the one that is available above on the surface such as from lakes, rivers whose source is from rain or snow melting at mountain caps. On the other hand, groundwater is one that comes from beneath the soil or rocks that remains accumulated. Specifically, only 3% of the total water available on earth is certified as freshwater that can be utilized for consumption. Certainly, groundwater is one major source that is heavily harvested for drinking water purposes widely. Needless to say, technologies are constantly been on research like desalination of seawater that contains a high amount of salt to make it available for human consumption. CONTAMINATION OF WATER Undeniably, this water from their source while reaching to your home on their home meet with several contaminants such as sand, silt, TDS including salts of potassium, nitrates, magnesium, chlorine, as well as heavy metals like lead, arsenic or mercury a big thanks to the contribution by human & industrial waste that find themselves in this water sources, making it undesirable for use. To be speaking of, mud, sand or silts are the visible impurities. Chlorine is one chemical that the municipalities use to disinfect the water and excessive of it beyond prescribed levels makes is damaging for the human body. Groundwater & water from the river or lake is good ground for breeding of organic impurities like viruses, cysts, or bacteria. On the other hand, TDS minerals are one common fundamental found in water along with other impurities like arsenic that is used widely in fertilizers thereby deteriorating the quality of water. Understanding these impurities present in the different sources of water, basically, will make us realize the importance & purpose of water purifiers in making the water clean & safe for drinking. TOTAL DISSOLVED SALTS (TDS) Particularly, the word TDS is making quite around in every other paragraph. What exactly is TDS? Well, TDS measured in mg/L or parts per million (PPM) denotes the concentration of dissolved salts both organic & inorganic present in water. These are so small they can easily pass through the cloth or ordinary filter. Needless to say, there are salts like calcium, magnesium, or sodium that are included under TDS but are essential for better growth of the human body. As a result, a particular concentration is always recommended for safe human consumption. On the other hand, salts of minerals like lead or arsenic even in a small amount can cause substantial damage to the human body. The acceptable limits of TDS in water can be categorized as: Below 300 ppmExcellent for useBetween 300 to 600 ppmBetter for human useBetween 600 to 900 ppmFair & considerableFrom 900 to 1200 ppmLow level of TDSAbove 1200 ppmAbrupt & unacceptable level of TDS Certainly, according to the BIS Standard of 10500-2012, 500 mg/L TDS level is quite desirable for human use. However, it may happen water of 500 mg/L may even contain a higher amount of arsenic, cadmium, or lead concentration in it, which doesn't make it palatable & act as slow poison. On one hand, TDS of water can be checked easily at home with the Digital TDS meter available online. But knowing individual constituents of TDS in water is important for better & healthy consumption. Digital TDS Meter PURIFICATION TECHNOLOGIES: Precisely, the water pollution in India is at an alarming range and with all other aspects discussed above, water purification becomes a must during these days. Certainly, some advanced technologies have been devised by different brands to overcome these issues. The 3 major purification techniques include Reverse Osmosis (RO), Ultraviolet light (UV) & Ultra Filter which have their own advantages & disadvantages. Apart from them, there are other filter cartridges as well that are present in the purification mechanism for optimum output. SEDIMENT FILTER: Generally, these are to arrest the visible impurities like sand, silt present in the water. Water made available from the municipality is usually clear and thus it is not necessarily needed in these cases, however, groundwater has multiple visible floating impurities. Particularly, they are placed at the outer body of the main mechanism to help increase the durability & life of the RO membrane. PRE & POST ACTIVATED CARBON FILTER: Carbon is a better absorber in terms of filter, it widely arrests the organic volatile compound from water thereby removing the bad odor from the water. Generally, the pre ones are installed ahead of the RO membrane whereas the post one is installed after the RO at the last stage. In particular, it tends to enhance the taste of water while removing the odor. REVERSE OSMOSIS: Certainly, talking in the science aspect, water that is pure from impurities and has a low concentration of it can easily move towards water having higher concentration through a semi-permeable membrane. However, the reverse of this is to be applied while purifying the water, which needs the water to be pressurized against the semi-permeable membrane. Altogether, this is reverse osmosis. And, the semi-permeable membrane being so fine with small pores easily arrest the TDS salts, heavy minerals causing the wastewater to drain off and pure water to pass ahead in the purification process. Generally, speaking a good amount of water gets wasted as a drain during RO, while some water purifiers have adjustments for collecting & using this water for different household purposes. Basic RO Water Purification (Source: Kent) ULTRAVIOLET PROTECTION: All in all, the ultraviolet chamber uses an ultraviolet radiating light that helps to diminish the slippage bacteria & viruses from the RO process. Needless to say, it helps to kill 99.99% of organic pathogen impurities from the water making it extremely safe for drinking purposes. ULTRA FILTER: Subsequently, this is the filtration process that uses a 0.001-micron pore filter and works without electricity usage. it helps to trap any residual contaminant that slips after the RO purification step. All in all, when water is contaminated with heavy metals it is advisable to opt for RO purifier, as it proves optimum for arresting it. However, if except for TDS readings & visible impurities, you aren't aware of the existing other impurities and are in doubt it is best said to go for Universal water purifier that houses RO, UV & UF altogether to give optimum purified output. TDS CONTROLLER vs MINERALIZER: Eventually, the water that passes through the RO membrane becomes pure & fit for drinking. However, while controlling the TDS of the water, the RO membrane arrests even the vital minerals such as salts of calcium, sodium & magnesium from the water which is important for the human body. In order to tackle this issue, and replenish water with the essential minerals TDS Controller & Mineralizer are two of the technologies that are used in the best water purifier in India. Basically, in TDS Controller a part of the water is bypassed before the RO membrane and is purified in the UV & UF filtration and later mixed with the pure water coming from the RO filter to maintain the concentration limit of these vitals minerals. On the other hand, with the TDS controller, there is a small chance of contaminating the RO purified water by bypassing it. As a result, to overcome this the Mineralizer technology comes in handy. In particular, it releases these essential minerals & replenishes the water the vital mineral content that is required to keep the water healthy for consumption. PURIFYING RATE OR CAPACITY: Particularly, this one of the most neglected aspects during the buying of a water purifier. Well, depending on the family consumption pattern & requirements, it is a must you should check for the purification rate as it helps to keep your drinking needs in check. Mostly specified in liters per hour, a good RO purifier can help purify 12-15 liters of water every hour, which is best suited & ideal for the majority of homes. In addition, some high-end models can have a purification capacity of 20 liters or more per hour.
