RO and Smart RO Advanced Drinking Water Systems
Reverse Osmosis systems' performance are influenced by feed water conditions such as pressure, temperature, TDS levels,
and hardness� The better these incoming conditions, the better the systems will perform at their rated specifications�
Influent Water Characteristics
Pressure
40-120 psi
Temperature
33° - 100° F
Total Dissolved Solids (TDS)¹
0-2500 ppm
(0-2500 mg/L)
pH

Chlorine²
0-3 ppm (0-3 mg/L)
Chloramine
0-3 ppm (0-3 mg/L)
Turbidity
0-10 NTU
Hardness³
0-10 gpg
Iron
0-1 ppm (0-1 mg/L)
Bacterial Quality
Potable
¹ Rating at 50 psi, 77oF, 500 mg/L TDS influent, without storage tank�
² May vary with pressure� See
Capillary Flow Restrictor” on page <?>,
for all hard water applications where TDS
exceeds 1000 mg/L (ppm)�
³ A softener is strongly recommended for water over 10 gpg hard� Installing a system without a softener on water
with hardness higher than 10 gpg will reduce the life of the membrane� The Arsenic cartridge must be installed
after the RO membrane� All specialty cartridges must have a Performance Indicator Device (PID) installed to track
gallon usage�

* Depending on local water quality and use environment, the actual filtered water flow rate and total filtered water
volume will vary�
* Recovery rating means the percentage of the influent water to the membrane portion of the systems that are
available to the user as RO treated water when the systems are operated without a storage tank or when the
storage tank is bypassed� The systems’ recovery rating has been verified with test data�
* Membrane element specification� System daily production rated to pressurized storage tank 27�8 gpd (Aquasential
RO) and 34�1 gpd (Aquasential Smart RO)�
