Dewatering Box

Dewatering Box

Heavy duty separation of solids and liquids.

The Dewatering Box has a heavy-duty screen mounted above the floor on the inside so that material entering the box is separated into solids and liquids. The solids remain on top of the screen while the liquids drain down to the bottom of the box. One use for Dewatering Boxes is when draining firewater ponds during heavy equipment excavation. The contents of the pond are pumped out and into a Dewatering Box, allowing the water to drain from the solid particulates and then decanted out from the box via filter. The solid waste may then be disposed

The false floor system is designed to provide a partially open filtering cage above the container floor to support waste materials and allow liquid contents to drain into the void area below. This is accomplished by installing a cage constructed with a carbon steel punch plate floor and expanded metal walls 13 inches above the container floor. This cage is supported by a series of stands and is welded in place. The cage starts at the rear door and extends to the front dog house or slant front wall. The area around the dog house is covered with 3/16 plate. The cage spans the width of the container between the walls. The drain, a 4″ pipe nipple with ball valve, is located at floor level, just behind the front side post.
