Durable Sewage Treatment Equipment Active Sludge Treatment Fine Bubble Membrane Diffusers
RSD series have RSD144, RSD245, RSD330 3 types, RSD144 is large bubble disc aerator, RSD245/RSD330 are fine bubble disc aerators.
Features:
Excellent counterflow prevention function
The back stops are all equipped with valves to avoid counterflow
when the air transmission is broken off, enabling the pores to shut
smoothly and applicable to intermittent operation. Its unique and
even air vents can lead the airflow effectively, and can prevent
sewage water from flowing into the aerator pipeline effectively.
Long guaranteed life
EPDM membrane is a special elastomeric polymer with high
non-deformability and anti-tearing index. The membrane is made at
even thickness with small pressure. Special processing technology
is used to overspread 6000 micro-pores on the surface of the
membrane. Under running condition the air bubbles rise with spiral
whirlpool, giving self-purification ability to the membrane. The
life of the membrane under normal use is guaranteed for 5 years,
but usually it is necessary to use it together with the water
removal system.
Unique ring seal
The aeration head tightening ring provides tight sealing effect
between the aeration head base and the membrane washer -- the
higher the air pressure, the better the sealing effect.
Easy installation
PVC soft connector can be installed directly without any other
auxiliary tools. The operation is easy and convenient.
