A liquid treatment system has a housing defining an interior space. The housing has an inlet port for receiving liquid into the interior space of the housing and an outlet port for allowing liquid to exit the interior space of the housing. The outlet port is spaced from the inlet port so that liquid flows through the interior space of the housing from the inlet port to the outlet port. An ultrasonic waveguide assembly is disposed within the interior space of the housing and includes an ultrasonic horn disposed at least in part intermediate the inlet port and the outlet port of the housing. The ultrasonic horn is operable at an ultrasonic frequency to ultrasonically energize liquid flowing within the housing. An ultraviolet light source emits ultraviolet light into the interior space of the housing to treat liquid flowing therein.

In a process for dyeing a textile web having a first face and a second face opposite the first face, dye is applied to the textile web and the web is then moved in an open configuration thereof over a contact surface of an ultrasonic vibration system with the textile web in direct contact with the contact surface of the ultrasonic vibration system. The ultrasonic vibration system is operated to impart ultrasonic energy to the textile web to facilitate the distribution of dye throughout the web. The web is then moved further in its open configuration through a microwave application chamber of a microwave system and the microwave system is operated to impart microwave energy to the web in the microwave application chamber to facilitate binding of the dye to the web.

In a process for dyeing a textile web, dye is applied directly to a first face of the textile web other than by saturating the web. The web is moved in an open configuration thereof over a contact surface of an ultrasonic vibration system with a second (opposite) face of the textile web in direct contact with the contact surface of the ultrasonic vibration system and the first face free from contact with the contact surface of the ultrasonic vibration system. The ultrasonic vibration system is operated to impart ultrasonic energy to the second face of the textile web to facilitate movement of the dye from the first face of the web into and through the web to the second face thereof. In another embodiment, dye is applied to the first face of the textile web without applying the dye to the second face of the web.

An ultrasonic treatment chamber and a process for ultrasonically treating a liquid in an ultrasonic treatment chamber include an elongate, generally tubular housing having an inlet and an outlet spaced longitudinally from the inlet. Liquid is directed into the housing at the housing inlet for longitudinal flow within the housing to the housing outlet. Mechanical ultrasonic vibration is generated within the housing in direct contact with the liquid flowing within the housing, with the direct contact being upstream of the housing outlet. A standing acoustic wave is produced within the housing with the standing acoustic wave having a node spaced longitudinally from the housing outlet.

In a process for dyeing a textile web having a first face and a second face opposite the first face, dye is applied to the textile web and the dyed web is then immersed in a flowing treatment liquid with the textile web in a generally open configuration. A contact surface of an ultrasonic vibration system is immersed in the flowing treatment liquid with the contact surface in direct contact with at least a portion of the textile web immersed in the treatment liquid. The ultrasonic vibration system is operated to impart ultrasonic energy to the portion of the textile web immersed in the treatment liquid at the contact surface of the ultrasonic vibration system to facilitate the removal of unbound dye from the textile web for entrainment in the flow of treatment liquid.
