This trailer mounted container box utilizes a ten foot by five foot filter bag to remove particulate from water at up to 400 gpm. Place the empty bag filter on the mesh top of the container box and connect the inlet pipe or hose to the bag inlet. The bag retains the particulate and the water passes through the bag and is captured in the container box. The container box features a four inch outlet for controlled draining. When the bag is loaded drain the container box and transport the bag to the disposal site in the trailer and dump it with the hydraulic lift bed. This is a one man operation with no extra equipment required.
