  1. Why RO Purifiers are considered better than UF Purifiers?

    Post by : Zerob

    Why are RO purifiers better than UF?
    What happens to the impurities in the RO purification?
    Are RO Purifiers better than UF purifiers?
    How does RO process work?
    How does a UF purifier work?

    To understand how RO Purifiers score over UF Purifiers we need to delve slightly into the purification process of both these purifiers.

    Lets start with the RO Purifiers first.

    In RO Purifiers purification happens following a process of Reverse Osmosis. To understand the process of Reverse Osmosis, let us take a closer look at the Osmosis process. Osmosis is a process in which water molecules flow across a semi permeable membrane – from a region of lower solute strength to a region of higher solute strength. The solute strength in this case refers to the TDS (Total Dissolved & Suspended Impurities) level of water. The water thus in an Osmosis process moves from across the membrane from a region of lower TDS level to the region of higher TDS level

    In the RO process the Opposite happens. Hence the name Reverse Osmosis. In this process water is forced to move from a region of higher solute concentration to the region of lower solute concentration. This is achieved by pumping water at a higher pressure inside the RO Chamber causing water molecules to be flow through the membrane to the other side leaving behind dissolved solids and other impurities. The impurities that are left behind are drained out through another outlet. The water that passes through the semi permeable membrane in the RO Purifier has a much lesser concentration of TDS than the original inlet water.

    So, when the water has high TDS and is Hard, RO Purification is the most effective

    Since the water needs to be pumped at a high pressure to help it pass across the membrane, RO Purifiers will need electricity to perform this task. Hence the RO Purifiers cannot operate without electricity

    In an UF or Ultra filtration Purifier, a semi permeable membrane like in case of RO Purifier is used but the holes in the UF Purifier are much larger compared to the holes in the RO purifier and as a result water passes through the UF Filter using the force gravity and without any additional applied pressure. Thus UF Filters work without electricity and should be considered for use where the TDS level of water is low and the water is not Hard

    Do RO purifier need maintenance?
    How often does RO purifier need maintenance?
    How periodic does a RO purifier need to be maintained?
    What steps to take to make the purification of water optimal?
    What to do after the post filter stage?

    For a Reverse Osmosis Water Purifier to function optimally, it needs to be periodically maintained.
    The frequency of maintenance depends on the extent of use of the system. Though whether or not a purifier is used heavily or sparsely, one needs to get it serviced at least once in a year’s period to ensure the filtration is happening right and that the scaling of the membrane is not much.

    There are a few important steps we need to take unless and until you are using an advanced RO Water Purifier like the ECO RO Water Purifier

    To make the purification system perform to the peak of its ability, the following needs to be routinely followed:

    Regular Filter Changes

    This will depend upon the upon how many stages of purification is being used in your RO Purifier.

    Sediment Filter
    The sediment filter which helps in straining ot the dirt and the silt needs to be changed at least once a year to prevent clogging of the membrane.

    Carbon Filter
    The carbon filter that removes chlorine and other harmful chemical contaminants affect the water’s taste and odor and should be changed once a year.

    RO Membrane
    RO membranes do not need replacement very often. Under normal circumstanes then can be safely changed once in 3 years but in case the overall maintenane of the system is not done and the RO Membrance gets affected due to this then this may need a change as well.

    Post Filter
    The Post filter in the final stage of Purification in an RO Purifier and it helps in removing any residual odor and foul taste in water to ensure you get completely pure and fresh drinking water.

    If the RO Purifiers are not maintained from time to time as explained above the RO Membrance which is the heart of the Purifier may get affected leading to inferior quality of output water and also a reduced life span of the Purifier

    Do you need a water softener?
    Does hard water damage your health?
    Is water softener at your home advisable?
    Can hard water cause damage to gadgets?
    Can the fittings in kitchens show stains due to hard water?

    Water Softeners help in making Hard Water soft. Water in some regions are predominantly hard, chiefly due to the presence of Hard Water Ions of certain minerals.

    You can easily make out whether the water supplied to your home is Hard or not from the effect it has on the various fittings you have at home, the garments you wear and even your skin and hair.

    If the water supplied to your home is Hard you may find stain marks in your ceramicware or any ceramic fittings after a period of continued use. The fittings and appliances in your kitchen like the geysers or bathroom can show scales or stain marks due to these being in constant touch with water

    Moreover hard water can impact your skin and hair and make them look dull and straw-like and your skin feeling dry and itchy. White clothes may start appearing grayish and colors may look faded due to the presence of hard water ions.

    Though Hard Water is not found to cause very significant damage to ones health but it can cause damages to the gadgets and appliances used in ones homes. Hence for a longer life of your garments, appliances and your plumbing systems, a water softener is a must.

    Is RO water acidic?
    Is RO water not good for health?
    Is acidic water harmful?
    Do all RO purifiers have pre filters?
    What serious ailments are caused due to acidic water?

    Some people are of the opinion that Water from an RO Water Purifier is Acidic and hence unsafe and not good for health. This is not correct. Water from an RO water purifier is the best water to drink.

    The fact is, though carbonic acid gets generated to some extent in the initial stages of purification, the special cartridges, containing alkali chemicals. that are used in the later stages of purification in an RO Purifier helps in removing all traces acid from water.

    Moreover, its important to note here that the Carbonic Acid that gets generated during the RO purification process is the same as the one that is present in aerated drinks we consume but in far lesser concentration. The final output water from the tap of the RO Water Purifier does not contain traces of carbolic acid as the acid gets neutralised by the alkaline cartridge before flowing out of the Water Purifier. It is worthwhile to also mention here that our stomach has far more stronger acid in the form of Hydrochloric Acid compared to the Carbonic acid that gets generated during the RO Purification Process.

    All RO water purifiers also have pre-filters which help in removing dissolved chemicals and chlorine from water before the water flows through the RO membrane. The RO membrane filter out organic molecules of pesticides, herbicides and VOC’s.

    For most of us having safe water means consuming water that is free from germs and viruses to prevent us from diseases like Cholera, Typhoid, Dysentery, etc. Though these are serious ailments but modern day medicines can easily cure these ailments. Also just by boiling the water one can make sure that water is free from such germs.

    But much more dangerous than microbiological impurities are the impurities present in the form of dissolved chemicals, especially the salts of Heavy Metals like Arsenic, Chromium-6, Lead, Mercury, etc. which can cause lifelong damage and early death. We may not even know that we are being slowly poisoned due to heavy metal contamination, because there appears no difference in taste or smell of water. These can only be detected by chemical analysis of water.

    The Heavy Metal in water tend to ‘bio-accumulate’ in our body, which means that once heavy metal is absorbed, our body cannot get rid of it. So even though there are no immediate problems the heavy metals in our body keeps on accumulating as more and more water gets consumed by us. Finally Heavy Metal poisoning symptoms start showing up. By then it usually becomes too late. Heavy metals in water causes life threatening diseases like cancer can cause nerve damage, stunted growth in children and also early death. Children suffer most from heavy metal pollution of water. Boiling the water does not remove dissolved heavy metals from water.

    So how can we be absolutely safe from being poisoned by heavy metal in drinking water. The answer is to use a Reverse Osmosis or RO water filter purifier.

    Only an RO Water Purifier can remove heavy metal and other dissolved salts present in water while also removing bacteria and viruses present in water to provide almost distilled quality water.

    How to decide the right water purifier in your home?
    What is advisable to select the right purifier in your home?
    Are carbon filters effective against bacteria?
    Can filters remove food taste?

    Purification of water is a much discussed topic these days due to the very high levels of pollutants present in our environment.

    Though there is a wide variety of water purifiers available, choosing the right purification technology is key to having pure and safe drinking water.

    A normal water filter is designed to filter out the contaminants. Contaminants such as dirt, rust and dust are simple to remove from water by using sediment type water filter. These can be used on a single faucet at your home.Then there are Carbon filters.
    The Carbon filters score over the sediment filters because these filters can remove foul taste and odour from water along with other dissolved chemicals that may have contaminated the supply water.

    The sediment and carbon filters however are ineffective against bacterial and viral contamination by pathogens like E. coli, Coliform, Cryptosporidium and others. The best way to disinfect water or remove these pathogens is by killing them so that they do not threaten your health. The process of eliminating the pathogens or the disinfection process in water purifiers can be either chemical based as in chlorine disinfection or it can be non-chemical based like UV or ultraviolet radiation. In chlorine based disinfecting process, chemical chlorine gets added to the water supply to kill pathogens while in a UV based disinfecting system the UV rays helps in killing all pathogens instantaneously.

    The advantages of a chemical free disinfecting process over a chemical based one is that with a UV system there is no need to use dangerous chemicals and.secondly, the chemical based disinfection process produces harmful byproducts known as VOC during the purification process while the UV purification process produces no such harmful by-products,

    Nowadays, in most of the urban localities it is get to seen that even if the source water gets well treated to remove contaminants, the water gets cotaminated again with a variety of contaminants like chemicals, heavy metals, pathogens while getting distributed to homes. To tackle the problem of the presence of pathogens, heavy metals and chemical contaminants present in supply water, Reverse Osmosis purifiers are used to efffectvely filter out or remove all these type of contaminants. The membranes of RO Purifiers have pore sizes of around 0.001 thousands of micron and hence can effectively help remove these impurities.

    In order to get high quality water one needs to be sure about the quality of supply water and basis that select the proper technology to eliminate the specific problem. A proper water purifier will help safeguard you and your family’s health against health problems caused by contamintion of water
