1 Introduction
When Modules are not in operation, suitable storage conditions must be provided to prevent membrane
degradation. Storage and transport precautions must be observed at every step of the life of the Modules
from shipment to delivery to the job site and beyond when units are put in storage for extended periods of
time. Storage requirements differ for PP and PVDF and for submerged or pressure type products.
Storage and transport requirements for MBR Modules are described elsewhere.
Definitions:
• Module' -The Memcor assembly of Hollow Fibre Membranes sealed with "pots" at each end.
• Spare Module—a wet Module sealed in a plastic bag & packaged in either individual or 4 Module
cardboard cartons.
• Array—An assembled housing for a MEMCOR°CP or XP (pressurized) unit.
• Cell — An open tank that contains the Submerged Membrane Filtration Module Rack(s)
• Empty Array—an Array with no Modules installed.

2 Transport from Australia
Modules can be shipped as Spare Modules or already installed in an Array in the case of pressurized
systems. In transit, the following recommendations must be followed for PP and PVDF Modules and
Arrays.
2.1 Shipping Recommendations
• Modules and Arrays containing Modules must be shipped at ambient temperatures >0°C and
<40°C (32-104°F), kept dry to avoid deterioration of packaging, and protected from direct
sunlight.
• When shipping to cold climates where there is a risk of freezing:
o Modules must be transferred to a temperature controlled truck or shipping container at
the port of entry for road transport.
o Arrays will be shipped as Empty Arrays. These should be kept covered to prevent water
ponding or debris collecting on surfaces. The Modules will be shipped separately and
transferred to a temperature controlled storage location via temperature controlled trucks
as indicated above.
• Spare Modules are protected by a carton and are sealed in a black HDPE bag with a small
amount of water to maintain a humid environment. If opened for inspection, the bag must be
resealed or the Module must be placed in a new, sealed bag with a small amount of water
(approximately 100 mL)to maintain a humid environment.
• Spare Modules and Arrays must be kept sealed. Spare Modules must remain in original
packaging and crating until installation.
• Arrays shipped with pre-installed Modules are shipped with a small amount of drinking water
added (dechlorinated drinking water for PP Modules)to maintain a humid environment.
• Arrays or crates containing Modules must not be subjected to significant mechanical shocks. A
ShockWatch° Indicator(Fig. 1) is attached to each Array and each crate containing Modules
when more than 56 Modules are part of the same shipment. If the ShockWatch° Indicator is
found activated, accept delivery but notify shipping agent and supplier.
• Temperature dataloggers (Fig. 2) are included in some shipments for temperature monitoring.
Follow the directions on the instruction sheet accompanying any datalogger.

3 Storage of Spare Modules as Inventory
Maintenance of stock in locations outside of Australia may be required in order to meet timely delivery,
satisfy local market requirements or comply with regulatory or customer-driven requirements. Storage of
Modules as inventory must comply with the following:
• Store all Spare Modules in accordance with all instructions printed on the shipping carton:
o Store flat
o Store indoors and away from direct sunlight
o Do not expose to temperatures :500C or>40°C. Storage between 50C and 250C is
preferred.
o Keep dry (dampness leads to deterioration of the carton)
o Do not"end stack"
o Identify bags leaking and re-bag Modules when identified
• Rotate stock—Spare Modules typically carry a one year warranty commencing upon delivery.
4 Storage during Assembly Process
This section covers storage needs for Modules used during the unit assembly process. Typically, this
section applies to pressure Modules (M10, L10 and L20) installed in Arrays that are being assembled with
other equipment to form a pre-assembled unit.
• Arrays are to be kept sealed at all times except when the necessary connections to external
pipework are made. Blanking spades are provided to assist with this. If Modules are installed and
arrays are not going to be worked on within 7 days the Array should be completely filled with
clean (fresh) drinking water(dechlorinated for PP Modules). Store Array on level ground and
drain before moving or commencing work.
• During Assembly, Arrays must be stored under the following conditions:
o Store away from direct sunlight
o Do not expose to temperatures :500C or>40°C
• Any external pipework must be thoroughly cleaned before removing blanking spades to prevent
debris from entering the Array.
• After connection of the pipework and instruments, the Arrays must be filled with a small quantity
of water to maintain a humid environment. If a unit is pressure-tested after assembly, a small
amount (approximately 10L)of drinking water must be maintained in the Arrays after the test to
maintain a humid environment.
• When Modules must be removed from an Array or cell, observe the following recommendations:
o Modules should be kept moist at all times.
o For temporary storage, small quantities of Modules should be immersed in a tank filled
with drinking water(dechlorinated for PP)for less than 48 hours. Take steps to prevent
microbial contamination or damage caused by swarf by covering the tank.
o For larger quantities of Modules and/or Modules that need to be stored for more than
48 hours, Modules should be re-bagged and stored as spares (Section 3 above).

5 Transport to Job Site
Apply the same criteria as per Section 2 and ship within the temperature range >0°C and <40oC (32-
104°F). In climates where there is a risk of freezing or extreme heat, it will be necessary to ship Modules
in a temperature controlled environment.
Where it is not feasible to ship in a temperature controlled environment, it may be necessary to schedule
shipments to avoid these periods of temperature extremes.
6 Storage at Job Site
This section described the storage of Arrays and Spare Modules at the customer's site prior to
installation.
• Spare Modules should be stored in accordance with the instructions printed on the carton. Refer
to Section 3.
• Arrays must be stored at ambient temperatures >0°C and <40°C (32-104°F), kept dry and
protected from direct sunlight. Arrays should be covered or stored indoors to prevent water or
debris collecting in the top isolation valve area.
• If Modules are installed and Arrays are not going to be worked on within 48 hours of delivery the
Array should be completely filled as below:
o If storage time will exceed 7 days, use appropriate storage solutions as per section 7.
o If storage will be for less than 7 days then it is acceptable to use clean (fresh)drinking
water(dechlorinated for PP)
7 Storage after Installation
This section describes the procedures for storage of systems for shutdowns greater than 7 days for
surface water systems, and shutdowns greater than 3 days for waste water, coagulant dosed &seawater
systems.
• If Modules have been in operation, perform a standard CIP in accordance with site operating
instructions, otherwise proceed to next step.
• Open all filtrate isolation valves
• Fill system with storage solution.
o For PVDF membranes this is a maximum 5 ppm sodium hypochlorite solution in clean
(fresh)drinking water or RO permeate.
o For PP membranes this is 0.5% MemClean EXA2 (or 0.25% sodium hydroxide)with a pH
of approximately 12.8 and conductivity of 12.9 mS.cm-'.
• Measure and record free chlorine concentration and pH of storage solution.
• Once a week inspect for leaks and add more water if necessary
• Monthly for surface water systems and weekly for wastewater, coagulant dosed & seawater
systems
o Recirculate the solution and measure and record the free chlorine concentration, pH &
conductivity of storage solution.
o For PVDF membranes, if residual free chlorine is<_ 0.5 ppm top up with sodium
hypochlorite solution to a maximum of 5 ppm.

0 For PP membranes, if pH <12 add more sodium hydroxide to increase the pH to 12.8
• Monthly for wastewater and coagulant dosed systems drain and refill the unit with fresh drinking
water or RO permeate
• Maintain plant room temperatures to avoid freezing conditions or recirculate via the CIP system to
ensure water in the Array cannot freeze.
• When Modules must be removed from an Array or cell, observe the following recommendations:
o Modules should be kept moist at all times.
o For temporary storage, small quantities of Modules should be immersed in a tank filled
with drinking water(dechlorinated for PP)for less than 48 hours. Take steps to prevent
microbial contamination or damage caused by swarf by covering the tank.
o For larger quantities of Modules and/or Modules that need to be stored for more than 48
hours, Modules will be re-bagged and stored like spares (Refer Section 3.1).
8 Freezing Conditions
It is recommended that freezing conditions be avoided. Frozen Modules are extremely brittle and any
mechanical shock may cause substantial damage. Freezing may void warranty on Modules and Array
components. Ship and store Modules in a temperature controlled environment if necessary.
If freezing of an Array or cell is unavoidable observe the following precautions prior to freezing occurring:
• If Modules have been in operation, perform a standard CIP in accordance with site operating
instructions, otherwise proceed to the next step.
• Complete a backwash and drain down the system
• Completely drain the unit and all pipework
• Protect the Modules from drying out
o For pressurised systems seal or isolate the Array to prevent the entry of contaminants
o For submerged systems remove Modules from the cell and place into sealed plastic
bags.
• Avoid all mechanical shock
• Allow Modules to thaw before moving, handling, or filling with water.
