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： Disclosed is a dissolved air floatation (DAF)-type pretreatment apparatus. The dissolved air floatation (DAF)-type pretreatment apparatus includes: a floatation tank for removing foreign objects of floating matter, turbid matter, or alga contained in raw water of seawater, sewage, or wastewater; a filtering compartment part provided in the floatation tank and having one surface and the other surface which are partially opened to allow treatment water obtained by primarily removing floating matter from raw water to pass therethrough; and a plurality of filtering balls confined in the filtering compartment part and including a fibrous or spongy material to filter turbid matter or floating or suspended solids remaining in the treatment water introduced to the interior of the filtering compartment part.
