5. Air Diffuser Cleaning
The clogging of diffuser holes causes uneven air diffusion and membrane clogging,
and the racks are broken in the worst case. Please clean the air diffusers once a
day to prevent such trouble.(it is recommended to install the automatic air diffuser
cleaning system with automatic valves).
The air diffusers are cleaned up with the reverse flow of the sludge from the
diffuser holes into the diffuser pipes, which is generated by the air jet flow from the
compressor through the air diffuser pipes to the branch discharge nozzle.
Air diffuser cleaning procedure
Fig.12 Condition when air scrubbing Fig.13 Condition when stop operation
(1) After do the air scrubbing (Fig.12), close V1 and V2, open V3 and V4 valve
(Fig.13). At this step, the water from the tank comes through the diffuser
holes into diffuser piping, and is discharged with the water (Stop operation).
(2) Keep this stop operation condition for about 5 seconds. After that, open V1
and V2 valve. At this step, the material deposit inside the diffuser holes and
diffuser tank will come out through V3 and V4 together with the water
(Cleaning operation, see Fig. 14).
