A method and apparatus for increasing dewatering efficiency of a solids-laden liquid stream in a wastewater treatment facility, whereby a liquids-solids stream is pumped into a mixing apparatus in a closed-channel liquid flow conduit configuration, where the liquids-solids stream is intensely mixed with air and polymer in a mixing zone created by an adjustable flow restriction device, performing similar to a venturi to increase the velocity, agitation, and turbulence of the liquids-solids stream internal to the mixer, where the introduction of air and polymer to the stream is introduced independent of mixing energy. Compared with current methods and apparatuses to mix polymer with solids-laden wastewater, the present method and apparatus requires less energy, where it enables the addition of air independent of mixing energy, and it creates a zone of mixing with greater mixing efficiency via increased turbulence.

The present invention provides a set of ozone water manufacturing device which can greatly reduce an unpleasant smell of ozone gas when ozone water is used for sterilizing hands and feet, and can save power consumption of a pump which operates for preventing stagnation of a water stream in an electrolytic bath. The ozone water manufacturing device includes an electrolytic bath and a mixer which atomizes air bubbles of the ozone gas in the ozone water flowing out of the electrolytic bath. Each of the electrode assemblies in an electrode unit within the electrolytic bath is inclined at the predetermined same angle in a vertical direction. The mixer includes a mixing case bottom and a mixing case main body. A vortex flow generating plate generates a violent water stream from the water stream within the mixing case main body.
