Maintenance of Bluebox 1800UF
Daily
1. Cleaning of the float-filter:
Screw off the red balloon and plastic top. Remove the nylon and metal
filters. Rinse them in clean water with a brush. Affix the filter and check
that the crude filter is placed on top (see ill.).
2. Cleaning of the three pre-filters:
a) Screw off the three white filter housings using the admitted key to avoid
damage on the houses. (See ill.).
b) Remove the filter from the plastic pipes and rinse both the pipes and
the filters with clean water (see ill.).

Side 8 af 16
The filters must not be wrought or squeezed to get remaining water
out.
3. Reinstall the filters in the pipes and screw them into the sockets.
4. The front filters should be changed when clogged. Pay special
attention to filter 2 (05 micron) and the Activated Carbon filter should
be changed every 4 months of operation irrespective of its visual
condition(se ill.).
5. Filers on the front of the electric box, these filters have to be cleaned from
dust e.g. every day.
6. The filters on the electric box have to be changed every month.
Every month
1. Lubrication of the pump.
The pump is lubricated with grease at the point where the arrow marked
“grease” (see ill.). Remove the black plugs on the front of the Bluebox, to
reach the grease point (see ill. Side 2)
2. Maintenance routines:
Check that all the connections and clamps are tightened.
Tighten front filters, RO filters and UV-light bulb.
Check that the drainage pipes in the container are not blocked.
Check all hoses for holes, tears and other breaches of water-tightness.
Check the pump’s membrane (if there is water leaking out of the small
hole at the bottom of the pump, the membrane is not watertight and must
be changed.

Cleaning
To make sure that the prescribed cleaning fluids are
working correctly, the system must be run with and
without pressure, which means that the blue handle at the
main block (see ill.) are in open position and then turned to
closed position.
For cleaning, a clean tank with a capacity of approx. 50 litres must be used, and clean
water must be available.
1. On screw the pre-filters and pull the inside out. Screw the filter
housings on again without the filters in.
2. Pre-rinse with clean water for 10 minutes.
3. Alkali cleaning (Divos 116)
If using RoClean or similar powder detergent, please revert to
separate dosing procedure in the back of the manual.
Dilute 0.25 liter DIVOS 116 with 50 litres of water in the tank.
Start Bluebox 1800UF and let the system rinse without
pressure (blue handle in open position = “pressure off”) for 10 minutes. After that
the blue handle are turned to “Pressure on” and the Bluebox 1800UF must work at
this setting for 30 minutes at 2-3 bar’s of pressure.
4. The system must now rinse with clean water for 10 minutes without pressure, and
then 10 minutes at 2-3 bar’s pressure.
5. Acid Cleaning (Divos 2)
If using RoClean or similar powder detergent, please revert to separate dosing
procedure in the back of the manual.
Dilute 0.5 liter DIVOS 2 with 50 litres of water in the tank. Start the Bluebox 1800UF
and let the system rinse without pressure (blue handle in open pressure = “pressure
off”) for 10 minutes. After that the handles are turned to “Pressure on” and the
Bluebox 1800UF must work at this setting for 30 minutes at 2-3 bar’s pressure.
6. After 30 minutes have passed, the tubes are placed in the tank, which is now filled
with clean water, and the system has to run for 15 minutes in “Pressure of”. After
that let the pump run for 15 minutes with the blue handle turned to “pressure on” so
that Bluebox 1800UF is rinsed all the way through.

Side 10 af 16
7. When the cleaning is finished, the system is closed down as described in “Part III –
After using Bluebox 1800UF” (see ill.) and the 3 front-filters have to be changed. If
the first filter, 25 micron, is not too damaged (clogged), it can be rinsed and brushed
down and reinstalled (see ill.).
8. After more than 14 days of standstill and before storing, the Bluebox 1800UF must
undergo a complete cleaning process as described above.
9. If the unit is not in use for longer than 14 days or stored, the membranes can be
treated with a 20% glycol solution, which will also protect it against freezing
temperatures. Pure H2O can also provide a membrane conservation product in
powder form for optimal transport. This product does not possess an anti-freeze
feature.
10.Remember to run a cleaning process of the system before taking into use
afterwards.
Cleaning Procedure with RoClean products
The RO plant is organically or biologically fouled and requires cleaning. Avista
Technologies recommend cleaning with low pH then high pH cleaners RoClean P303 and
RoClean P3111. This stepwise approach has been found to give good results in the past
with each wash reaching deeper layers of the foulant.
Caution
When cleaning with low pH first it should be certain that no hydrocarbon fouling can have
occurred on the membranes. If in doubt reverse the order of cleaner application and start
with the high pH clean.
All cleaning procedures should be carried out within the membrane manufacturers’
guidelines which in this case are:
DO NOT EXCEED
LIMIT
Cleaning Temperature
45oC
Cleaning pH (not below lower or above upper)
2 –11
Cleaning Flowrate
9-10 m3/hr/8” pressure vessel
Cleaning differential pressure (MAX)
65 psi (6 element vessel)
Each array of membranes should be cleaned in parallel and the production of
permeate should be minimised by keeping the differential pressure low. The permeate
lines should be kept slightly open to prevent backpressure damage.
We would additionally recommend that the differential pressure should not exceed
40psi during recirculation and that temperature should be raised as close to the
membrane temperature limit as practical to achieve the most efficient clean possible.
This is most important for the alkaline clean.

Side 11 af 16
The following procedure should be repeated for each bank of membranes to be cleaned.
Detailed Cleaning Procedure
1. Flush Train
The train to be cleaned should be shut down and flushed with dechlorinated potable water
until the brine and feed conductivities are within 10% of each other (approx. 10 minutes).
2. Acidic Wash
A2% w/v solution of RoClean P303 should be made up by adding 1kg of RoClean P303
per 50 litres of heated potable water. The water should be heated to aminimum of 15oC
and a maximum of 45oC. The total volume of cleaning solution required should be detailed
in your Operating and Maintenance manual.
Once the solution is mixed and the pH has been verified to be 2.5>pH<3.5 introduce the
cleaning solution to the (feed/brine side of the) plant at a low flow and displace the flushing
water to drain before diverting the flow to the CIP tank. Keep the cleaning fluid in contact
with the membranes for atotal of 2hours stopping and starting the recirculation pump
every 15 minutes to allow deep soaking and scouring action on the foulant layer. The
recirculation flow should be increased to the point where the differential pressure reaches
40psi or where the flow reaches 10 m3/hr/pressure vessel.
Note the pH, temperature, differential pressure, flowrate and any discolouration/changes to
the cleaning solution on a half hourly basis as before.
At the end of this period pump the solution out of the system and drain down to remove as
much solution as possible.
3. Flush out Remaining Acidic Solution
Rinse out the cleaning tank and then fill it with un-chlorinated potable water. Rinse each
pressure vessel until the conductivity of the outlet is within 20% of the inlet.
4. Make Up High pH Cleaning Solution and Circulate It
A2% w/v solution of RoClean P111 should be made up by adding 1kg of RoClean P111
per 50 litres of heated potable water. The water should be heated to aminimum of 30oC
and a maximum of 45oC and it should be confirmed that the pH of the solution is between
10>pH<11.
Introduce the cleaning solution to the (feed/brine side of the) plant at a low flow and
displace the flushing water to drain before diverting the flow to the CIP tank. Keep the
cleaning fluid in contact with the membranes for a total of 2 hours stopping and starting the
recirculation pump every 15 minutes to allow deep soaking and scouring action on the
foulant layer. The recirculation flow should be increased to the point where the differential

Side 12 af 16
pressure reaches 40psi or where the flow reaches 10 m3/hr/pressure vessel. The
permeate valve should be left (slightly) open to prevent any membrane damage.
Note the pH, temperature, differential pressure, flowrate and any discolouration/changes to
the cleaning solution on a half hourly basis.
At the end of this period pump the solution out of the system and drain down to remove as
much solution as possible.
5. Flush out Remaining Alkaline Solution
Rinse out the cleaning tank and then fill it with un-chlorinated potable water. Rinse each
pressure vessel until the conductivity of the outlet is within 20% of the inlet.
6. Restart the Plant
Return the plant to operating mode and start up the unit. Allow the unit to settle down for
an hour and take a set of readings.
The feed pressure and differential pressure should have improved significantly but the
product quality might have drifted off slightly. The quality will be expected to improve over
the next 24 hours as the membranes tighten up again after high pH cleaning.

[IMPORTANT NOTE]
Please be aware of the following:
Make sure that the electricity supply is stable.
The purification membranes in the Bluebox 1800UF system normally have to be changed
every 2 years depending on the working hours and quality of feed water.
Please do not place the system in directly sunlight. Heat may affect the electronics in the
switch board box.
As the UV-light contains glass, the system must not be affected by hard shock.
The system must be free of dust and dirt.
The system must not be exposed for frost. Temperatures below 0 (cero) degrees Celsius can
ruin the membranes. E.g. during a long-haul flight, the Bluebox should be started with low
pressure for a while in order to defrost the membranes without damaging them. For long
term storage in freezing temperatures, please contact www.pureh2o.net
([email protected]).
As an industrial standard for Reverse Osmosis, membranes output decreases with
temperature of raw water. (3% reduction per 1 degree C measured from 25 degree C)
The industrial standard for Ultrafiltration membranes shows a lesser effect from colder feed
water, but the capacity should be expected to be reduced.
Beware of silt, humus and high levels of iron in the raw water. These compounds will
eventually spoil the membranes, since very small “plates” from these compounds will fill up
the membranes over time. The only way to deal with this is to install an improved pre-
filtration system.
