Part I: RO BASICS
This section provides basic concepts on how an ROES system works, how it performs in relation to your
house’s water condition. We hope this information helps keep your ROES system running at top
performance for years to come.
1) Basic Terms
GPD = Gallons Per Day (flow rate)
PSI = Pounds per Square Inch (pressure)
TDS = Total Dissolved Solids (contaminants)
PPM = Parts Per Million (unit used to measure TDS level)
TDS Meter = A digital meter for measuring the TDS level in the water
2) Flow Diagram for 6-Stage RO System:
Fig. 15 below shows how water flows through the RO system from Feed point to Output point.
Input water starts from Main Water Supply, going through stages 1, 2, 3 pre-filters, then enters the stage-4
membrane. Product (filtered) water from the membrane feeds the storage tank; the “brine water” from the
membrane drains out through the drain line. Product water from the tank passes through stage-5 filter then
stage-6 filter before reaching the dispensing faucet.
