摘要： A nonpowered mixing and coagulation basin is provided, which generates turbulences of at least two kinds inside the mixing and coagulation basin to which the raw water flows so that foreign matters contained in the raw water come into contact with each other while circulating by a water flow to be coagulated into a predetermined size, and a dissolved air floatation device using the same. The nonpowered mixing and coagulation basin has multiple stages with different packing materials and packing densities to form turbulent flows inside the raw water and control a flow speed, thereby uniformly mixing raw water and coagulant to enhance coagulation efficiency. The nonpowered mixing and coagulation basin simultaneously carries out mixing and coagulation at the front end part of the water treatment system, reduces equipment expenses by having no electric motor and agitator, and reduces power consumption because it does not use any power unit.

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.

摘要： A nozzle for a dissolved air flotation system includes a housing, a nozzle connector, and a nozzle body. The housing has an inlet formed at one side and an outlet formed at another side. The nozzle connector couples to the inlet and has an inflow path formed in a longitudinal direction. The nozzle body is disposed in the housing, and includes: a collision portion formed at a first end portion of the nozzle body such that a fluid introduced along the inflow path of the nozzle connector 10 changes its flow direction and collides with an inner wall of a side portion of the housing, a plurality of faces formed at sides of the nozzle body, a plurality of side paths defined between the faces and the inner wall of the housing, and a spurt hole defined at a second end portion of the nozzle body.
