摘要： The present disclosure relates to a dissolved air flotation system using ambient air, and more particularly, to a dissolved air flotation system that is capable of allowing ambient air to be introduced in front of a pump to generate micro air bubbles with the water discharged from the pump, so that the ambient air may be used instead of compressed air.

摘要： A hybrid type fiber filtering apparatus includes an enclosure, a strainer, a first filtering layer and a second filtering layer. The enclosure has an upper case and a lower case coupled to the upper case. The strainer is mounted inside the upper case in a longitudinal direction. The first filtering layer includes a plurality of fiber filters fixed between upper and lower fixing units and surround an outer circumferential surface of the strainer. The second filtering layer includes a plurality of fiber ball filters disposed inside the lower case. Raw water introduced into the upper case through a raw water inflow pipe passes through the first filtering layer, flows into the strainer, drops downwardly from an inside of the strainer, is introduced into the lower case, passes through the second filtering layer, and then, is discharged out through a filtered water discharge pipe.
