    Default Domestic RO and water with high TDS

    I have a friend living in an area where the water is quite high in TDS ...around 4000 ppm...is this considered brackish water ?

    Is it possible for him to install an RO unit for drinking water ? (he needs about 20 liters per day)...if so ,what kind of system would be suitable for him ? He doen't really care if he has to change membranes every 6-8 months but he needs to be sure that the RO water will be clean enough to drink it.

    Are the standard domestic systems suitable for these applications ? or the standard TW30 membranes will not last even a day ?

    Thanks...

    so best way instanll a prefilter : like ultrafitration or mesh filter
    then install RO SYSTEM to protect longer use life

    What other water test results do you have? Hardness, iron, sulfides, sodium chlorine?

    More information would be needed.
