This product is a device for high load, odor, and bulking countermeasures. Using "NIIKURA SHARDIS", air is sent to the adjustment tank, and oxygen can be efficiently dissolved in the sewage (circulation is operated in the adjustment tank). If the amount of N-Hex (normal hexane extract content) is about 1,200 mg/ℓ, the pressurized flotation device can be dispensed with, eliminating the need for chemicals, leading to cost savings and reducing the burden of maintenance such as inspections. Retrofitting is easy, and you can actually set up a demo unit and check the effects.
