A wastewater management system includes a series of water treatment modules to treat wastewater and produce reusable and/or potable water and other beneficial byproducts of the wastewater treatment process. A pretreatment module, a filtration module, an evaporator module, an odor control module, a UV-light module, an autoclave module, a sonolysis module, an ozone module and a chlorination module are combined in multiple combinations along with holding tanks, condensers, flash tanks and other components to address water purification and reclamation needs based upon specific wastewater conditions. The system captures condensate from AC systems and rainwater from rainwater gutter systems processes the water to produce reusable and/or potable water with or without re-mineralization. Any CO.sub.2 produced by the water treatment system is captured and processed using naturally-occurring flora. The wastewater treatment system includes multiple closed-loop subsystems to minimize energy usage and maximize water purification and reclamation for reuse.

A process and an apparatus continuously treat seeds with ultrasonic transmission. The process includes mixing seeds with a flowable medium to create a flowable slurry of seeds; continuously moving the flowable slurry of seeds for a length of a flow pipe through a helical path within the flow pipe; and as the flowable slurry flows through the helical path within the for the length of the flow pipe, subjecting the seeds to ultrasonic transmission created by ultrasonic transducers arranged along the length of the flow pipe. The seeds in the flowable slurry are subjected to the ultrasonic transmission having such waveforms and being transmitted in a manner so as not to damage the seeds and to produce ultrasonically-treated seeds that have regulated germination characteristics, such that plants resulting from the ultrasonically-treated seeds when the seeds are planted have affected growth characteristics. The apparatus effects this process.

A fluidic device includes: a channel that extends along a first axis and through which a fluid flows; an ultrasonic transmission part that is disposed at the channel and transmits an ultrasonic wave into the channel along a second axis orthogonal to the first axis in response to an input of a drive signal; and a controller that controls the ultrasonic transmission part. The controller measures impedance of the ultrasonic transmission part at a time when the ultrasonic transmission part is driven while changing a drive frequency of the drive signal within a predetermined range, specifies a drive frequency at which the impedance is a local maximum and sets the drive frequency at which the impedance is a local maximum as a first drive frequency, and inputs the drive signal of the first drive frequency to the ultrasonic transmission part.
