    Problem in Water purifying system


    Want to resolve issues with a water purifying system? Searching for detailed methods of solving the issue without the help of technicians? Find advice from experts here.

    We have RO water purifying system in our house kitchen. It gets water from pipe directly for purification. But the a pot full purified water got filled after wasting another pot full water from pipe. When we called the technicians they come and tell this and that and changed something in the purifier. The same condition persists again.
    Is this a correct way that wasting equal part of water to get purify?

  • There is generally some water wastage in using RO water purifiers. I am also using the RO water purifier for the last ten or more years. By experience, we know how much may be the wastewater coming out when we operate the machine to fill the output storage tank. So we keep a large vessel at the wastewater outlet and collect he full quantity and use it for various purposes like vessel washing, floor mopping, and other miscellaneous use.

    The wastewater quantity depends on the inlet water quality and output water standard kept. Suppose your water output standard is set to say 50 ppm-level. Now if the input water TDS is 100ppm, the purification load is less that is, TDS has to be brought down from 100 to 50. But if the input water TDS is 300 then it takes more load and generates more water to arrive at 50 ppm.

    If your RO water purifier has a TDS control valve/switch /screw, then you can adjust yourself by trial and error or getting guidance from the RO technician. RO technician will have the TDS measuring meter and he can tell you the TDS level of input and output water. Some technicians set the output level TDS to very low levels like 10 or 15. If it is so, please ask them to change it around 40-50. This will give good taste to the water. Low TDS gives some bitter taste to water.
    You can also avoid more wastage by scheduling the power 'On" time to the optimum. From your experience, you know what will be a day's consumption of purified water. Fill the storage tank at one stretch. Keep a large vessel at the waste outlet end. Collect the wastewater in the vessel and use it for purposes like watering potted plants, mopping the floor, washing vessels, etc. This will save water waste.
    After the output storage tank is full, power off the machine. Power it again only when the storage level is low. Again fill it one stretch as earlier.
    Nowadays' as per guidelines RO water purifier manufacturer has come with 'Zero water waste' purifiers. You can buy them. Or you can contact the manufacturer if he can upgrade your existing purifier to a zero-waste grade by some addition or technical tweaks.
    Call the technician. Let him do servicing. Ask him to check the RO filter.Ask hime to check and adjust the TDS levels.

  • This is an inherent problem with RO plants. Recently some RO plant versions without water wastage are coming I heard but I have never seen.

    All the RO plants are having wastages like this. The quantity of wastewater will depend on the quality of the raw water you are using. If the hardness of the water is high, the wastewater generation will be more. I have seen some plants where the wastewater will be double the purified water. Another factor is what is the quality of water you are getting after purification for drinking. The lower the ppm level of hardness you have set, the higher the wastewater generation. So these two things are to be checked to decide on the water wastage.
    The maintenance of the plant is another issue. The membrane that is used is also costly and you have to change it once in a while. The life of this membrane will also depend on the quality of input water and the quality of the purified water. But overall the RO plant is costly and maintenance of RO plant is also costly. That is why these many people are not going for these systems.
    If the water you are having a TDS of less than 300 PPM and if there is no fluorine, you need not go for RO plant. SImple candle filter will be sufficient. This will remove all suspended solids and you can boil the water and drink. In this process, there is no water wastage.
    In fact, RO water will not have any minerals. So that water will not give you any strength. That is why we have to add some minerals to it. Otherwise, drinking RO water is of no use.
    You have to ascertain the quality of water and you have to decide on the quality of the water you want. Based on this you have to ask the technician to fix the machine so that water wastage will be in control,
    You can collect the wastewater that is coming out from your RO plant and that can be used for cleaning of utensils. You can collect it and give it to your servant maid and she can use it for utensils cleaning. Another use is that you can use that for washing and cleaning.

  • Reverse Osmosis (RO) technology use membrane system for purification of water; when a high-pressure waterfall on the membrane the pure water filtered from one side and those water does not pass in the membrane got back to out pipe of the system. Generally, 2./3 of water wasted by RO system, We need to use that water for gardening, etc,

    In RO type of water filters a lot of water is ousted from the machine and generally goes waste. Some people reuse it as the volume is substantial. In many house it simply goes waste. So far the RO technology is like that but there are always technological improvements in the gadget and may be tomorrow some entrepreneur might design a RO machine with less or no water wastage. Till that time we have to bear with these limitations of the present technologies.
