1
At feed water TDS of 250 ppm and temperature of feed water of 25 °С, ±10%.
2
If pressure of water in your system does not meet requirement, install a pressure booster pump to raise it. If
water pressure exceeds the upper limit, install a pressure regulator before the RObust.
3
Using the RObust with feed water temperature between +20 and +30 °С produces a lower rejecon rate and
higher ow rate, which yields higher TDS of puried water. Using the system with feed water above +30 °С is
advised against.
