Q:
Normally for the first time use of the RO system, the water seems to have
white bubbles in it, which is normal and totally drinkable. It is because when
the pump is pressurizing the water, it will pressurize the air at the same time.
It will make the air molecules smaller, thus the solubility further increases.
The air can’ t be released at that time because of the pressure in the RO
system.However, when you turn on the tap to get a cup of water, the pressure
of air is released. So you will see a huge number of bubbles in the water. It
looks cloudy and white, but they are just bubbles. After you put the water
still for a while, all bubbles will be gone, the water is totally good for drinking.
Osmosis is a natural phenomenon happens in all RO system, no matter if you
have a conventional RO system or tankless RO system. When the RO system
starts to work, pressure from the pump overcomes natural osmotic pressure,
forcing feed water through the RO membrane that removes the impurities.
When the RO system stops working, the pump stops offering pressure as
well. At that time, because of different concentrations, a small fraction of
ions will enter into pure water and cause TDS to rise by a small amount.
However, even if the TDS reading is a little high at the beginning, the quality
water is still unbeatable by any other filtration methods including carbon,
KDF, ceramic, UF, UV, etc.. The water is totally good to drink and you don’ t
have to wait for about 1 minute to get the water, since the whole system will
not release any harmful substances to the water. The TDS removing rate for
PX500-A is about 94-95%, if your incoming TDS is high, the outlet TDS will
be high too.
The first two stages of the system are able to eliminate more than 99.99% of
all substances from your tap water, removing more than 94% of TDS value.
The pure water then goes through the 3rd remineralized stage of the system
which restores essential minerals, adjusts pH level and further polishes the
water taste, serving customers with optimal water solution. However, the
essential elements such as calcium and magnesium may raise the TDS value
of the water again.
If you consider the remineralized water to be undesirable, please contact us
for an exchange of the last alkaline filter to universal post carbon filter.
