Abstract: A folding divider device for separating and transporting items on a truck bed. The divider device includes a first and second panel pivotally connected by a spring-biased hinge that allows the device to open and fold for installation and uninstallation. The surface of the panels comprise one or more channels, wherein one or more dividers are removably attached thereto. The dividers are positioned perpendicularly to the panels to create compartments therebetween. The device further includes inserts that can be used to adjust the length of the device so it fits within a user's truck bed. To prevent the device from shifting while in use, the inserts can removably attach to end pieces, wherein the end pieces can attach to the sides of a truck bed. In the alternative, the inserts can removably attach directly to grooves on the sides of a truck bed.

Abstract: A storage tank is described that can be used for on-site storage of liquids, sludge or solids. Advantageously, the storage tank can be adapted to provide various functionality including a double walled containment system. Further, the storage container may be adapted from an intermodal container and include corner castings of a twist lock mechanism.

Abstract: A retractable mixer system and a method of using the retractable mixer system to clean sludge build-up in a tank is disclosed. The retractable mixer system includes a drive shaft, a retractable propeller assembly and a motor for rotating the drive shaft and the retractable propeller assembly attached to the drive shaft. By using the retractable mixer system at an existing access point or a newly created access point, the sludge build-up may be cleaned even when the sludge level is above the access point.
