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.
