A method for removing fouling from a pipeline includes determining the location of fouling in the pipeline. Once determined, the method further includes installing a hot tap in the pipeline. A flex conduit is inserted into the pipeline through the hot tap and a treatment fluid is flowed into the pipeline through the conduit. The treatment fluid is used to remove the fouling from the pipeline. Once the fouling is sufficiently removed, the flexible conduit is removed from the pipeline.

A drain treatment system includes a supply interface, a drainage interface, a water distribution assembly, a pod housing, and a controller. The supply interface is configured to connect to a water supply, the drainage interface is configured to connect to a drain, and the distribution assembly is configured to receive water from the water supply via the supply interface. The pod housing is configured to retain at least one pod containing a drain treatment compound, and the controller is configured to control a transfer of the water from the water distribution assembly to the pod housing, wherein the water is configured to carry the drain treatment compound from the at least one pod to the drainage interface for delivery to the drain.

Ingredient dispensing systems and methods in a fluid mixture system using a monitored chamber pressure are disclosed. One system includes a chamber, an inlet to the chamber, a set of ingredient reservoirs, in the chamber, storing a respective set of ingredients and sealed by a respective set of valve, a pressure source, and a controller. The system is programmed to set a pressure of the chamber using the pressure source and the inlet to the chamber. The system is also programmed to dispense, using the pressure, at least two ingredients from the respective set of ingredients by actuating at least two valves from the respective set of valves.

A system for cleaning an implanted blood pump, comprising: an inflow catheter having an expandable inflow member positioned about the periphery thereof; an inflow tube coupled with the inflow catheter; a valve assembly coupled to the inflow tube; an outflow tube coupled to the valve assembly; and an outflow catheter having an expandable outflow member positioned about the periphery thereof, the outflow catheter being coupled to the outflow tube. In use, the inflow tube and outflow tube extend through the skin of a human body, the inflow catheter and outflow catheter are positioned within the human body, and the valve assembly is positioned outside the human body.

Valve and related assemblies, systems, and methods may include a self-cleaning feature that may be configured to at least partially displace material from a portion of the valve. Such valves may be utilized in a pressure exchanger.

A fluid feeding apparatus includes: a first connection portion configured to be connected to a first container in which fluid is stored; a second connection portion configured to be connected to a second container in which fluid is stored; a first flow path that communicates with the first connection portion; a second flow path that communicates with the second connection portion; a resistance portion configured to generate a difference of conduit resistance to cause one of the first flow path and the second flow path to be higher in the conduit resistance than the other flow path; and a switching portion switching a level relationship of the conduit resistance between the first flow path and the second flow path.

The present disclosure provides coupling systems for use in industrial systems to removably couple one or more components to the industrial system. The coupling systems discussed herein employ a flexible sleeve in addition to one or more components. The flexible sleeve can have a component disposed therein. When pressure is applied to the flexible sleeve, the flexible sleeve constricts around the component, securing the component in the coupling system and thus to the industrial system. Once the component is secured, the industrial system executes one or more processes on the component. The coupling systems discussed herein can accommodate components of varying internal and external geometries as well as internal and/or external coatings and surface finishes.

The present invention relates generally to cleaning waste collection systems such as but not limited to sewers, sumps, wet wells, collection tanks, digesters, clarifiers, classifiers, etc. and in particular to cleaning and removal of solid and liquid materials therefrom. In another embodiment, the present invention relates to an improved slurry hose and/or pipe for use in connection with cleaning waste collection systems such as but not limited to sewers, sumps, wet wells, collection tanks, digesters, clarifiers, classifiers, etc. and in particular to cleaning and removal of solid and liquid materials therefrom.
