RCD-270 / 330
MATERIAL OF DIFFUSER
High quality EPDM membrane and its oil content less then 12%
The membrane must close quickly when stop air supply¡AThe self-cleaning design prevents clogging and highly resistant to fouling, therefore the membrane surface include at least 6000 perforations¡CThe water hydrophilic property great then at least 70%. 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%
The disc base and retaining ring shall be molded high quality P.P( POLYPROPYLENE) . The physical characteristic is as follows:
Specific Gravity 0.905
IZOD Impact Strength 15.5 kg-m/cm
Tensile Strength 4000 PSI
Tensile Elongation 9%
Maximum Temperature 100¢J
Check valve¡GEPDM
Connection to the air header¡G3/4¡¨ PT 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.
