A passive fluid treatment assembly is provided including a passive treatment body defining a primary flow path and a liquid treatment path. The liquid treatment path bypasses a portion of the primary flow path and enters a treatment enclosure through a high pressure port. The fluid entering the high pressure port is treated by a treatment media in the treatment enclosure and exits through a low pressure port into a mixing chamber where it is remixed with the fluid in the primary flow path. A one-way valve is operably coupled to an outlet of the high pressure port for preventing the flow of treated fluid from exiting the treatment enclosure through the high pressure port.

A fluid injection system for dispensing a solution into a fluid flow in a flow line, the fluid injection system including a storage tank having a product to be dispensed therein. The system includes a connector for connection to a fluid flow line. The connector has an outlet port for diverting fluid from the flow line into the tank, an inlet port for returning a mixture of fluid and/or product back into the fluid flow line, and a restrictor provided between the inlet and outlet ports. The system includes an inlet dip tube and an outlet dip tube provided inside the tank and a mixing chamber connected between the inlet dip tube and the outlet dip tube. The mixing chamber is configure to mix the fluid with the product to create a fluid/product mixture, wherein the fluid/product mixture is injected back into the fluid flow line via the inlet port.

A mixing apparatus including a mixing region can have an inlet and an outlet. The mixing region can be operable to couple with a solution housing, thereby defining a mixing chamber. A stem can extend from a surface of the mixing region and the inlet can be disposed at a distal end of the stem. A wing can disposed at a proximal end of the stem and adjacently engaged with the surface of the mixing region and have a leading edge and a trailing edge.

A passive fluid dosing assembly and system is provided. The passive fluid dosing system may include a passive dosing body, a pressure plate, and a treatment enclosure. The passive dosing body may define a primary flow path and a liquid treatment path. The primary flow path may be defined between a fluid inlet and a fluid outlet. The liquid treatment path may be defined between a high pressure port and a low pressure port, bypassing a portion of the primary flow path. The pressure plate may be disposed within the passive dosing body between the high pressure port and the low pressure port. The pressure plate may define an internal orifice. The treatment enclosure may be positioned in fluid communication between the high pressure port and the low pressure port along the liquid treatment path. The treatment enclosure may define a solute chamber housing a dosed media.

A lance, in particular for jointly dispensing a pressurized fluid and an additive for penetrating walls, includes a lance body, a handle arrangement, multiple channels and actuator arrangements interacting therewith, a nozzle arrangement as well as at least one container for the additive. The actuator arrangements selectively control the fluid being conducted in the first channel, the additive being conducted in the second channel, and the ambient air being conducted in the third channel to a first nozzle body. The third channel forms a line connection between the ambient air and a mixing chamber of the first nozzle body. The second actuator arrangement with its second actuator directly acts on the third channel and indirectly controls the admixing of the additive via the second channel into the mixing chamber.
