Installation Instructions for Tubular Membranes
Remove existing clamps and membrane.
2. Clean membrane support tube to ensure that no debris remains in the airway.
Loose debris can block the membrane slits, this will adversely effecting the
system pressure and oxygen transfer efficiency.
3. Gently install new membrane on support tube. Membranes shorter than the
support tube must be aligned with the inlet end of the support tube. Do not
stretch the membrane to cover the support tube. Orient the non -perforated
portion of the membrane to cover the air outlets. This will ensure that the check
valve feature of the diffuser will operate.
Install membrane clamps.
Note: If clamps are provided by Diffuser Express the following instructions
should be followed. SS crimping clamps should be compressed with outside
edge of the clamp located 1/4" from the edge of the membrane and ear of clamp
placed on top of unit. Use crimping tool to install stepless ear clamps.
(Reference Figures 1 and 2.)

Operation Instructions for Tubular Membranes
The tubular membrane requires very little maintenance for long term operation. The
airflow should be kept within the ranges detailed in the original equipment IOM to
maintain the structural and operating characteristics of the membrane. Continuous
application of high airflows, greater than denoted for normal operation may result in
physical damage to the membrane. Maximum airflows should not be exceeded. Higher
airflows can increase system operating pressure. Excessive airflow rates may shorten
the life of the membrane. Note: Use caution when adjusting several lateral throttling
valves in the same piping system. This procedure can result in elevated airflows in
sections of the basin, exceeding the maximum allowable airflow to each membrane.
Maintenance Instructions for Tube Diffuser Membranes
1 The diffuser membranes should be protected from petroleum products, ie;
mineral oils and aromatic hydrocarbons.
2. To prevent clogging of the diffuser membrane, the blower system should be
equipped with paper inlet filters having a performance efficiency of 99.5%
removal of 2 micron particles.
J. it Is recommended to tube membranes on a regular basis, generally
every 12 to 18 months.
4. As a result of biological and/or inorganic materials building up on the membrane
surface, pressure build-up and/or increased headloss may be experienced over a
long period of operation. To restore membrane performance, one or both of the
following may be required:
Page 2 of 3
Insitu Cleaning of Membrane
Typically membrane diffuser units will require cleaning because of two common types of
surface build-up; biological and inorganic scaling. The recommended cleaning
procedure for both types of build-up are detailed below.
1. Biological build-up is characterized by a moss like growth. The recommended
cleaning procedure is to physically dislodge the growth either through gently
brushing the substance off or using low or high pressure hosing. The hosing
method is effective in removing loose surface deposits on the diffuser membrane.
Maintain minimum air rate to the diffuser during hosing operation. The length of
time required to remove deposits is dependent on the type of surface foulant,
water pressure, distance from unit, etc. Typically, 5 to 10 seconds is required per
unit.
2. Inorganic scaling is characterized by a granular mineral like precipitate that can
form on the membrane surface. If brushing and hosing the diffuser membrane
does not remove the scaling, contact EDI for further instructions.
Replacing Diffuser Membranes
1. Reference above installation instructions.
Properly operated and maintained, the FlexAir Tube Diffuser membranes will provide
years of high efficiency treatment with minimum operator attention. Questions
regarding FlexAir system operation, maintenance, etc. should be forwarded to the
Engineering Department, Environmental Dynamics International, 5601 Paris Road,
Columbia, Missouri 65202. (573) 474-9456
