① Industrial wastewater pretreatment.
② Treatment of aquaculture wastewater.

Details

With stronger adaptability to water quality and resistance to higher solid loads, it is widely used in water treatment processes with higher suspended solids, such as industrial wastewater pretreatment.

The structure is similar to standard air flotation, and a mud hopper is added at the bottom of the box to timely discharge the settled sludge.
