(2) Flushing the Effluent Control Valve

Rotate the valve back and forth from 0 to 100 several times to flush and reset the valve.

Preventing Blockage of Anaerobic Filtration Media

(1) Degassing / Agitating Anaerobic Media

Accumulated sludge on the anaerobic media could
cause a complete or partial blockage.

Agitate the filtration media gently by using PVC or
stainless steel pipe with less than 20mm outside
diameter. Nitrogen gas trapped in the media will be
released during this process.

(2) Backwashing Anaerobic Media

If the anaerobic media is blocked, connect pipe with a blower to backwash the media as shown below.
The end of the pipe should be above the bottom of the media so that the accumulated sludge at the
bottom of the tank is not disturbed.

For your information, the distance from the water level to the bottom of the media is 1,050mm for
CE4200 and 1,250mm for CE6000.
