DESCRIPTION
SSI’s PTFE membranes can be found In municipal & industrial
applications including dairy, pulp & paper, beverage and oil
refineries to name a few.SSI's PTFE membranes have been proven
since 2004 to improve fouling resistance to such an extent that
cleanings are in most cases reduced by a factor of 5 to 10 as
compared to standard EPDM membranes from the industry's leading
manufacturers.
Material Introduce
How does this benefit standard wastewater treatment plants –
bio-fouling and chemical precipitation result in plugging of the
holes of the diffuser. As the holes block, the air is being pushed
through lesser holes which means the blower is doing more work.
Also, air being pushed through lesser holes has higher velocity
which reduces bubble contact time and overall oxygen transfer
efficiency which means the blower has to provide more air to
provide the same amount of oxygen to the wastewater. Due to this
property, PTFE membranes maintain “like new” conditions for longer
compared to standard membranes. A consultant conducted an
independent study on a comparison of standard EPDM membranes with
PTFE membranes. The two samples were put in operation in the
Aerobic Digesters of the Front Royal WWTP in Virginia, USA. After
one year in service, the diffusers were pulled out in September
2010. Here are the images from the visual inspection of the
consultant.
ADVANTAGES
1. Single mold technology to reduce costs.
2. Available in 3versions7",9",12".
3. 3/4" M NPT connection.
4. High efficiencies(SOTE) and low-pressure drops tested according
to ASCE standards.
5. High resistance environmentally friendly polypropylene
body(100℃).
6. Membrane with low plasticizer content to minimize the phenomena
of loss of elasticity and shrinkage.
Installation Method
SSI disk aerator can be installed on PVC branch pipe through quick
connect saddle, Grommet connection, etc. SSI pre-installed aeration
disk, rotate 1/4 turn can be installed on the quick connect saddle,
this saddle is suitable for 9" and 12" aeration disk for
installation.

Reference Data
Remark: We MANUFACTURE OUR DISC DIFFUSERS WITH DIFFERENT TYPE MEMBRANES.
STANDARD MATERIALS ARE EPDM AND FLUOROELA STOMER LAYERED EPDM.
Intelligent Upgrade Options
- Patented PTFE membranes prolong the efficiency and reduce
whole-life costs.
SSI’s patented PTFE membrane barrier properties not only reduce
plasticizer extraction, shrinking, and membrane hardening but also
limit dynamic changes that can result from swell, such as creep.
Compared with uncoated products that are more susceptible to
increases in DWP due to more aggressive fouling and changes in
physical properties and weight, the PTFE-coated membrane improves
the consistency of DWP (Headloss) values over the product life.
This directly impacts long-term power costs and the ability of the
system to distribute air uniformly across the tank floor.
- SSI Telemetry – the inside story solves maintenance problems
At the click of a mouse, you will know the DWP of your diffuser
membranes, the airflow rate to that monitored diffuser, and the air
temperature in the submerged piping system. You can sense
vibration, pipe rollover, and water in the grid. Automatic moisture
purging and automatic acid dosing systems are available. Through
multiple cameras, you can see both inside the grids and surface
bubble patterns. Wet probes are also available for DO and WW
temperatures. Tracking all this data on a user-friendly online
dashboard facilitates communication between consultant and client,
manufacturer and rep. This smart technology lets you locate problem
areas and allocate resources more efficiently. SSI Telemetry is
your preventive maintenance hub in the heart of the plant.
