Vacuum Dewatering Box

Vacuum Dewatering Box

A vacuum box for separating solids from liquid material

Tidal Tank’s Vacuum Dewatering Box resembles our Vacuum Box with the exception of some internal differences, including a filter which separates solid particulates from liquid material. Vacuum Dewatering Boxes are often used in combination with vacuum trucks when cleaning storm drains during sewer cleaning. The vacuum line runs from the truck to the vacuum dewatering box, and then to the storm drain area. Waste material is pulled back through to fill the Vacuum Dewatering Box. The Vacuum Dewatering Box offers the ability to separate solid waste from liquids that may be drained back out if environmentally safe, resulting in less total material to transport and dispose.

The floor system is designed to provide a partially open support grid above the container floor to support waste materials and allow liquid contents to drain into the void area below the grid. This is accomplished by installing a grid constructed of galvanized “bar grating” 13 inches above the container floor. This grid is supported by a series of stands and is welded in place. The grid starts at the rear door and extends to the front dog house or slant front wall. This area around the dog house is covered with 3/16 plate. The grid spans the width of the container between walls. The drains are a 3″ pipe nipple with ball valves, and are located on both sides at floor level just behind the front side post.
