Abstract: In various embodiments, an application and platform comprising systems and methods for staging equipment rentals is given. In association with an equipment rental facility, a mobile application can be utilized to identify the nature, quantity and maintenance condition of selected equipment assets that can be rented. The mobile application can identify the staging status of a specific equipment asset, facilitating efficient selection of desired equipment assets in advance of arrival of a customer. Staging status, and additional parameters, can be displayed and acted upon based on visual elements in association with the mobile application such as color, icons, or other visual elements, and first and second visual elements can be used to provide significance.

Abstract: A tank assembly for the treatment of waste streams that include settling pollutants and floating pollutants. The tank assembly includes an inlet conduit, a first compartment that includes a first drain at a bottom thereof, a second compartment that includes a second drain at a bottom thereof, a third compartment that includes a third drain at a bottom thereof, and an outlet conduit. The second compartment also includes at least a first lamella filter package disposed therein. The third compartment also includes a skimmer, an underrun member and an overrun member. A liquid flow path is defined from the inlet conduit, through the first compartment, through the second compartment and the first lamella filter pack, through the third compartment, past the skimmer, under the underrun, over the overrun and out the outlet conduit.

Abstract: A sludge dewatering tank that includes a first wall, a second wall, a third wall, a fourth wall and a bottom that cooperate to define a tank interior, a first interior wall and a second interior wall. The first interior wall cooperates with the first wall to define a first drainage compartment and includes at least a first filter member. The first drainage compartment includes at least a first drain that communicates the first drainage compartment with an exterior of the sludge dewatering tank. The second interior wall cooperates with the second wall to define a second drainage compartment and includes at least a second filter member. The second drainage compartment includes at least a second drain that communicates the second drainage compartment with the exterior of the sludge dewatering tank. The first interior wall cooperates with the second interior wall to define a sludge space therebetween.

Abstract: A clarifier tank insert assembly configured to be inserted into a frac tank. The clarifier tank insert assembly includes a housing that defines a housing interior and includes a bottom opening, at least a first plate pack assembly disposed in the housing interior, and at least a first pipe positioned within the housing interior and above the first plate pack assembly. The first plate pack assembly includes at least first and second parallel plates and the first plate defines a plate angle with the bottom surface of the housing. The first pipe includes a plurality of inflow openings defined therein. A water path extends through the bottom opening, between the first and second parallel plates and into the inflow openings in the pipe.

Abstract: A rack assembly that includes first and second side wall assemblies, a mid center bar extending between the first and second side wall assemblies, first and second front cradle bars extending between the first and second side wall assemblies, first and second male nesting members secured to the top of the first side wall assembly, first and second female nesting members secured to the bottom of the first side wall assembly, third and fourth male nesting members secured to the top of the second side wall assembly, and third and fourth female nesting members secured to the bottom of the second side wall assembly. A front cradle space is defined between the first and second front cradle bars and a rear cradle space is defined between the first and second rear cradle bars.

Abstract: An assembly for mounting or dismounting a vehicle comprising a step that is structured to slide on an axis longitudinally along the vehicle on a rail. The step has a pivot assembly enabling rotation from a stowed position to open position and back. The slidable step can be stowed in place by engaging a latch mounted to the vehicle. A handrail assembly can be inserted into a handrail-receiving member to facilitate grasping a handrail upon mounting or dismounting the vehicle.
