In strategic cooperation with Niihuis of the Netherlands, we have introduced advanced high-speed dissolved air flotation (DAF) equipment and technology to provide efficient solutions for oil and phosphorus removal, biological sludge recirculation and separation, seawater desalination suspended solids pretreatment, and river water intake pretreatment. DAF equipment is classified according to its processing capacity and function into IPF (<135 m?/h), NPF (<500 m?/h), and GDF (activated sludge separation and recirculation, oil recovery).
