MATERIAL OF DIFFUSER
A. High quality EPDM membrane
B. The membrane must close quickly when stop air supply.
The selfcleaning design prevents clogging and highly resistant to fouling.The physical characteristic is as follows:
Tensile strength 2000 PSI
Tear strength 110 Lb/linear inch
Ozone resistance Pass
UV resistance Pass
Durometer 60 Ultimate
elongation 700%
C.The disc base and retaining ring shall be molded high quality ABS( POLYLAC) .
The physical characteristic is as follows:
Specific Gravity 1.06
IZOD Impact Strength 2.6 ft-lb/in
Tensile Strength 7090 PSI
Tensile Elongation 15﹪
Maximum Temperature 85℃
D. Connection to the air header：3/4” NPT threads
Features:
Low operating costs
Reduced energy consumption when we operated the membrane diffuser brings considerable cost savings
Constant back valve
The self-cleaning design prevents clogging and highly resistant to fouling
High oxygen transfer rate
Equally distributed micro pores on the diffuser membrane.Consistently produce 1-3 mm fine air bubbles that increase the surface contact area with water, greatly increasing the oxygen transfer efficiency.
Simple installation procedures
Diffuser range to be installed on most existing air header systems without special tools required.
Extended lifetime expectancy
EPDM membrane maintains elasticity and is resistant to even the most aggressive wastewater components
Reliable intermittent aeration operation
An integral check-valve system makes the diffuser ideally suited for air-on/air-off operations such as SBR’s
