Operational Description
Figure 2 illustrates one of three double acting Wa-
ter Cylinders (WC), stroking to the left as noted, con-
sisting of Pumping Pistons (P2 & P4), separated by a
Ratio Rod (R3). The Pistons are powered by the
Hydraulic Cylinder (HC) in a trapezoidal wave form
(Figure 3) by means of a Drive Rod (R1).
Feed Pumping Function:
1. Supply pump flow enters at S, to the P4 piston.
2. Feed flow exits from the P2 piston to F to the
SWRO membranes.
Reject Energy Recovery Function:
1. High Pressure Reject returns from the SWRO
membranes to R, then through an Energy Re-
covery Valve to the back of Piston (P2), into the
smaller Piston area chamber determined by the
Ratio Rod.
2. The Reject pressure assists the Hydraulic Cylin-
der (HC) to create the Feed (F) pressure.
Reject Discharge Function:
1. Low Pressure Reject from a previous stroke ex-
ists from the chamber between R3 and P4.
2. This low pressure reject discharges through an
Energy Recovery Valve to D.
Complementary Action:
1. There are three double acting pressure strokes
resulting in six (6) power strokes per cycle. Each
of these pressure strokes have complementary
flow profiles as shown in the Trapezoidal Wave
Form diagram (Figure 3.)
2. For system flushing all of the Energy Recovery
Valves can be put in the open position, allowing
flow from S through F and R, then exiting at D,
without operating the Hydraulic Cylinders (HC)
or Water Cylinders (WC).
