1: oily sewage is sent to the oil-water separator by the sewage pump, and after passing through the diffusion nozzle, large oil droplets float on the top of the left oil collection chamber

2: sewage containing small oil droplets enters the corrugated plate coalescer at the lower part, where the oil droplets are aggregated into larger oil droplets to the right oil collection chamber

3: sewage containing smaller oil droplets passes through the fine filter, and impurities in the water are removed, and then enter the fiber polymerizer in turn.

4: after separation, clean water is discharged through the discharge port, and the dirty oil in the left and right oil collection chambers is automatically discharged through the electromagnetic valve, while the dirty oil separated in the fiber polymerizer is discharged through the manual valve.
