The present disclosure relates to devices and methods for preparing a filtered solution from slurry for lateral flow testing of analytes of interest in agricultural or environmental samples. A porous frit is located adjacent to an outlet of a vessel containing slurry, and positive pressure is applied to the volume enclosed by a vessel body of the vessel to cause the slurry to pass through the porous frit and become a filtered solution that exits the outlet of the vessel. Devices and methods described herein allow more rapid, cleaner, and inexpensive production of filtered samples than conventional methods.

Systems and methods include a wing tool configured to be operable from work vessel(s), the wing tool including thrusters capable of fluidizing sediments from a first seabed location and moving it to a second seabed location, the second seabed location including a trench or differently shaped collection sump previously made by the wing tool and/or an extraction pump. The extraction pump operates from a second work vessel having sufficient capacity to pump fluidized sediments from the trench. Certain systems include a separation unit that separates sand from silts and clays and water from collected sediment. Systems and methods for reclamation of reservoirs, moving sand waves, for pre-trenching and/or recovering marine pipelines and cables, for removing cover from marine archaeological sites and for disposing of contaminated bottom materials in an environmentally acceptable manner.

Microdredging systems comprising a pumping platform and loading platform are described. In certain embodiments, system operates autonomously and is adapted to allow the loading platform undock from the pumping platform for disposal of the removed sediment.

Hydro excavation vacuum apparatus that process spoil material onboard the apparatus by separating water from the cut earthen material are disclosed.

In some implementations, a hydraulic coupling connection includes a coupling disposed at an end of a hose and defining a flange having: a lower surface configured to engage a body of a valve; an upper surface; and an outer diameter surface connecting the lower surface and the upper surface, the outer diameter surface defining a first plurality of straight sides; and a split flange engaged with the coupling, the split flange having: a first lower surface configured to engage the body of the valve; a second lower surface configured to engage the upper surface of the flange; and an inner diameter surface connecting the first lower surface and the second lower surface, the inner diameter surface defining a second plurality of straight sides, wherein engagement between the first plurality of straight sides and the second plurality of straight sides is configured to secure the connection at a first angle.

Mixing systems that include a mixer housing and one or more disk assemblies for mixing and processing materials is disclosed. The disks rotate to mix an additive into the material and to carry agglomerated solids toward a discharge of the mixing system. The disks may have a plurality of fingers or lobes which extend from a central portion of the disks.

The hydro excavation remote dig system provides for a primary and secondary dig tube attachments that permit a vacuum truck to be used for a remote dig setup. Specifically, the attachments include various attachable handles, corrugated tubing that connects to a reinforcement bar device with releasable clamps to maintain the corrugated tubing in an elongated state during use, a debris box with an integrated safety valve, and a dig tip.

Systems and methods for predicting replacement of a component of an industrial machine. One system includes an electronic processor configured to determine a wear rate of the component based on a current dimension of the component and historical dimensions of the component and determine a replacement cost for the component. Determining the replacement cost includes determining a cost of downtime for replacing the component based on a time for replacing the component and a downtime cost for the industrial machine during the time for replacing the component, a material cost in replacing the component, and an operating cost of the industrial machine associated with not replacing the component. The electronic processor is also configured to determine a replacement recommendation for the component based on the wear rate, the replacement cost, and discard criteria and output the replacement recommendation.
