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

Hydro excavation vacuum apparatus and fluid storage and supply systems thereof

Vacuum excavation apparatus having a deceleration vessel and methods for excavating a site

Hydro excavation vacuum apparatus

Systems and methods for dewatering slurries having relatively high solids content such as earthen slurries are disclosed. In some embodiments, one or more transducer devices configured for acoustic spectroscopy and/or electroacoustic spectroscopy are used to determine a parameter related to the particle size distribution (e.g., specific surfaced area) and/or zeta potential of the slurry.

Systems and methods for dewatering slurries

Airlocks for conveying material, hydro excavation vacuum apparatus having airlocks, and methods for hydro excavating a site

Hydro excavation vacuum apparatus having an adjustment system for adjusting a dewatering system screen

Hydro excavation vacuum apparatus having deceleration vessels and methods for hydro excavating a site

Systems and methods for dosing slurries to remove suspended solids from the slurry are disclosed. The systems and methods may be used to dewater slurries having relatively high solids content such as earthen slurries. In some embodiments, the zeta potential of the slurry is monitored by an electroacoustic zeta potential sensor to control coagulant addition.

Systems and methods for dosing slurries to remove suspended solids

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

Systems and methods for processing earthen slurries such as slurries of earth cuttings and, in particular, systems and methods that involve two separation units for dewatering the slurry or that involve additive mixing units are disclosed. The systems and methods may include a conveyor such as a drag-slat conveyor that removes slurry from a holding tank at which the material is dumped and toward the separation units to allow the material to be continuously processed and dumped into the holding tank.
