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.
