In sizing the TX RO, the output production based on average system operating conditions (and depending on
some factors) can change significantly.
Factors that must be examined include:
Water Temperature
This is the temperature of the water prior to entering the unit. The unique design of the TX RO will
transfer excess energy from the pump in the form of heat to the water as a part of its normal function.
This process will slightly increase the internal temperature of the water processed by the TX system,
allowing it to permeate more water. This added heat is incorporated into the product chart shown.
Working Pressure
The working pressure can be calculated using (4) pressure measurements:
Working pressure = System Pressure + Inlet Pressure – Osmotic Pressure – Back Pressure
The System Pressure (SP) is equivalent to the boost pressure of the TX RO's pump. For the TX
1440, this factor is 60 psi.
The Inlet Pressure (IP) is the dynamic pressure feeding the RO system. This pressure should be
either measured while the TX RO system is operating or when 3 gpm is flowing from the main
feed line.
The Osmotic Pressure (OP) can be calculated based on the inlet or feed TDS of the water. The
OP = TDS / 100.
The Back Pressure (BP) is determined by the type of storage tank connected to the system.
If an atmospheric storage tank is used, then BP = tank height / 2.3.
If a hydropneumatic tank is used, then BP = the average pressure between the tank's on/off set-
point 40/60 = 50.
