GENERAL
The ULTROclear (UC) Direct Feed (DF) low pressure reverse osmosis (RO) system is designed
to treat RO permeate/product water from an upstream first pass RO/watermaker system, directly
without intermediate break tanks. Installation of the Parker Sea Recovery low pressure
ULTROclear DF system is typically inside of a ship/vessel or inside of a building for land based
applications. The second pass RO system provides ultrapure water for spot free rinsing (zero
mineral deposits) and similar high purity applications.
Key Features:
Direct Feed operation treating first pass RO permeate directly without buffer tank(s)
Corrosion resistant low pressure RO system – coated aluminum frame
Run dry RO pump operation without damage – Robust & Reliable
Simple operation, ON & OFF automatic
Parker Quality – Parker Hannifin Corporation/Water Purification – Sea Recovery
INSTALLATION
Refer to the attached installation diagram
Step 1A: Place the RO system in a suitable location in the ship or building with enough room for
maintenance and servicing.
Step 2A: Secure the RO system down with appropriate anchorage and vibration mounts, as
necessary.
Step 3A: Connect ½” tubing (Parker Nylon N series tubing) to the INLET port on the connection
panel. Feed water is supplied directly from an upstream RO watermaker. Typical supply pressure
is 20 to 50 psi.
Note: The UC can treat onboard potable water or dockside potable water in addition to direct-feed from the
watermaker.
Step 4A: Connect ½” tubing to the BRINE port and route to drain or recycle back to the low
pressure piping of the seawater RO watermaker for 100% recovery.

C o n f i d e n t i a l P a r k e r S e a R e c o v e r y 0 6 1 2 2 0 1 7
Step 5A: Connect ½” tubing to the PRODUCT (RO permeate) port and route to the product
tank.
Step 6A: Connect the primary power supply (110V/1ph/60hz or 220V/1ph/50hz) to the RO
system.
Note: Provide appropriate fuse and/or circuit breaker protection upstream of the low pressure
dock water RO system, per all applicable electrical codes and guidelines.
Step 7A: Remove both prefilter housings and verify the prefilter elements are installed. Then
tighten both prefilter housings and secure them for operation.
Step 8A: Verify the BRINE recycle (BV-35) valve is fully OPEN (Direct Feed UC)
Note: The recycle valve can be throttled slightly for fine tuning, as necessary, but never
CLOSED
Step 9A: Check the system to ensure all fittings and connections are tight and ready for
operation.
INITIAL STARTUP AND OPERATION
Step 1B: Verify source water flow and pressure are available to the INLET of the low pressure
RO system.
Step 2B: Turn the black BRINE flow meter control knob clockwise (CW) until it is fully closed.
Then turn the black knob counterclockwise (CCW) two full turns (partially open).
CAUTION: Never operate the RO system with the black BRINE knob fully closed.
Step 3B: Turn the ON/OFF selector switch to the ON position. The RO system will START,
once the inlet pressure reaches approximately 40 psi (2.5 bar).
Step 4B: Gradually turn the black BRINE knob clockwise until the Filter OUT pressure is
approximately 35 to 50 psi, typically approximately 40-45 psi.
NEVER operate the UC system with the Filter OUT pressure over 55-60 psi, max.
Normal Operation: The DF ULTROclear will then turn ON at 40 psi and OFF at 20 psi
automatically, as a function of the upstream RO product water supply from the first pass RO
watermaker.

General Service Guidelines

C o n f i d e n t i a l P a r k e r S e a R e c o v e r y 0 6 1 2 2 0 1 7
Service and maintenance for the RO system depends upon many factors such as the source water
type, quality, frequency of operation, hours of operation per day, ambient conditions, and overall
installation. Regular maintenace is required in order to keep the ULTROclear Z series RO
system operating efficiently. The table below provides GENERAL guidelines for maintaning the
RO system.
Description Frequency Other /notes
Clean RO membranes 1-4 months
depending upon water quality and
operations
Record keeping and system monitoring Daily recorded with photos
Replace cartridge filters Monthly more frequently with higher DP
Replace carbon cartridge filters 2-4 weeks ORP to RO to be < 300mV
Replace pH neutralizing cartridge 1-2x/month monitor pH, replace if < 7.5-8
Flush RO membranes as req'd when not operating for more than 2-7 days
RO membrane replacement 1-5 years depending upon operations & cleaning
Replace carbon pretreat tank media 6-18 months monitor ORP daily
Replace media in prefilter MMF 1-4 years relating to source water turbidity/quality
Note: System warranty requires the use of only Parker Hannifin/Water Purification spares,
consumables, chemicals, components and appurtenances. Use of any other products or
equipment voids all warranty for the system. Daily operational information for all pressure,
flow, and conductivity in the system is required to be provided in the case of any warranty
claims. Pressure, flows, and conductivity must be provided for each flow stream with daily
recordings, photos and documentation.
ULTROclear (DF) System Cleaning
The ULTROclear DF RO system should be cleaned when the membrane pressure is observed to
increase by approximately 10-15% or at least once every 2-6 months. Cleaning involves
introducing Parker cleaning chemicals onto the membranes, soaking, and flushing the chemicals
out of the system. Cleaning always involves flushing the ULTROclear unit with clean
dechlorinated fresh water (or permeate) followed by the use of cleaner 1 and then cleaner 2.
1. Record all current flows, pressure and permeate conductivity for the system
2. Stop the UC system and flush the unit with dechlorinated fresh water or permeate with
the brine control black knob fully open, counterclockwise.
3. Turn the system off, open the downstream prefilter housing AC-20B and remove the
carbon/sediment prefilter.
4. Install cleaner 1, into the AC-20B housing
5. Remove the carbon/sediment filter from AC-20A and install a new carbon/sediment filter
6. Using fresh water feeding the system, turn the UC unit ON with the black brine control
knob fully open and flush the unit with cleaning chemical for approximately 5 minutes
7. Route the brine and product lines to drain
8. Stop the UC system and allow the chemical 1 solution to soak on the membranes for 5 to
60 minutes (longer soaks for more heavily fouled membranes)

C o n f i d e n t i a l P a r k e r S e a R e c o v e r y 0 6 1 2 2 0 1 7
9. Remove the cleaner 1 cartridge from the downstream prefilter housing AC-20B and
install a carbon/sediment filter element.
10. Flush the UC system for 5 minutes with fresh clean water to remove cleaner 1 from the
system
11. Stop the UC system, and perform the sames steps as noted above, but using cleaner 2.
12. End with a fresh water flush through the system and install two new carbon/sediment
prefilters.
13. With cleaning and flushing complete, restart the UC system under normal operating
conditions and record all new flows, pressures, and conductivity after 5 – 10 minutes of
steady-state operation.
Note: For extended RO system shutdowns for more than 2-4 days, perform a cleaning and then
flush a Parker preservative solution through the membranes.
Parker Membrane Preservative: 85-0103
Standard RO Cleaning Guidelines - Fundamentals
In normal operation, the membranes in reverse osmosis elements can become fouled by mineral
scale, biological matter, colloidal particles, insoluble organic constituents and other
contaminants. Deposits build up on the membrane surfaces during operation until they cause loss
in normalized permeate flow, loss of normalized salt rejection, or both.
Membrane elements should be cleaned when one or more of the below mentioned parameters are
applicable:
The normalized permeate flow drops 10%
The normalized salt passage increases 5 - 10%
The normalized pressure drop (feed pressure minus concentrate pressure) increases 10 -
15%
2-6 months of RO system operation (potable city/tap water or similar well water)
1-3 months of RO system operation (surface waters or similar)
1-4x/month (high fouling source waters/wastewaters)
If you wait too long, cleaning may not restore the membrane element performance successfully.
In addition, the time between cleanings becomes shorter as the membrane elements will foul or
scale more rapidly.
Please follow the guidelines below when handling, transporting and storing RO elements:
Protect from direct sunlight.
Store in a cool, dry place with an ambient air temperature range of 33°F to 95°F (1°C to
35°C).
Do not allow the elements to freeze.
Keep elements in their original packaging until required for use.
Do not store membranes for more than a year.
Use the record keeping charts and complete the monitoring tables at least daily.
