This invention relates to a transportable modular container system for fluid freight. The transportable modular container system comprises a container module including a reservoir configured to hold a fluid; an adjustable support for the container module, removably securable to a load area of a freight carrying transport and reciprocatingly adjustable between proximate and distal positions, the container module being located relatively closer to the load area in the proximate position than in the distal position, and wherein a zone for secondary freight is defined between the container module and the load area when the adjustable support is in the distal position and removably secured to the load area of the freight carrying transport; and a removable fluid flow control module for controlling fluid flow of the fluid between an external reservoir and the container module reservoir and releasably connectable to the container module.

An overfill valve associated with a drop tube segment fluidly connected to a fluid reservoir is described. The overfill valve includes a valve body positioned within the drop tube segment and a non-contact valve actuator positioned exterior to the drop tube segment and operable to actuate the valve body from an open position to a closed position without requiring any physical penetration through the wall of the drop tube segment. The non-contact valve actuator has a first position in which the non-contact valve actuator does not actuate the valve body from the open position to the closed position in a second position, achieved when the liquid reservoir reaches a predetermined level approaching the capacity of the liquid reservoir, the non-contact valve actuator actuating the valve body from the open position to the closed position when the non-contact valve actuator obtains the second position.

A storage container for storing quantities of acids and other volatile liquids is described having a recirculation system that can include a recirculation pump and a recirculation line that goes from a bottom end of the container toward a top end of the container, where the recirculation line has a plurality of pressure relief valves spaced along its length. The storage container may also include a leak detection system and a high level warning system.

Embodiments of the present invention include systems for storing large quantities of chemicals at a remote site. A controlled blending system balances the inflow of dry material and liquids into the blender based on a predetermined solid/fluid ratio. The blending system further balances the inflow and outflow of material from the blender.

A float probe configured to regulate fluid flow into a fluid container is disclosed. The float probe comprises an upper assembly having one or more outlets, a plurality of rods extending from the upper assembly to a lower assembly and a float assembly disposed between the upper assembly and the lower assembly. A first distal end of the rods is coupled to the upper assembly and a second distal end of the rods is coupled to the lower assembly. The rods extend along an outer surface of the float assembly and the float assembly is movable along the rods between a first position proximate to the upper assembly and a second position proximate to the lower assembly. The float assembly prevents fluid flow out of the outlets when disposed in the first position.

Methods of containing liquid introduced onto a support surface include forming the support surface with at least two mats, the mats forming a perimeter of the support surface. A plurality of berm members is positioned at least partially around or proximate to the perimeter of the support surface and extends upwardly relative to the mats sufficient to prevent liquid introduced onto the top of the support surface from leaking off of the support surface around the perimeter thereof.
