Patent number: 8079377Abstract: A washout container to which are mounted inclined ramps that allow a transit mixer, concrete pumping truck or other concrete handling vehicle to drive up over a portion of the container for dumping excess concrete and washing out waste concrete. The container cross-section may be rectangular to semi-circular, and is preferably fabricated with a steel structure. A watertight latching door assembly is coupled to the container to prevent leakage of collected liquid concrete waste material while allowing solidified concrete materials to be unloaded at a disposal site. The interior of the container is preferably lined with a material to which concrete will not adhere. The liner may be applied as a coating to the interior of the container or as a solid material retained within the container. In this way, solidified waste concrete can be easily removed from the container at the disposal site and preferably crushed for recycling.Type: GrantFiled: July 14, 2008Date of Patent: December 20, 2011Assignee: Concrete Washout Systems, Inc.Inventor: Mark Jenkins

Patent number: 7635434Abstract: Solid and liquid concrete waste is collected from a construction site and safely off-loaded at a treatment site. Solid waste is separated and sent to a crusher to be made into road bed aggregate. Liquid waste is put in a first tank to settle the solids, then moved to a second tank to settle remaining fine solids, and moved to a third tank coupled to a circulation pump with CO2 gas injection to lower the pH. The liquid in the third tank is then filtered before discharging for recycle, irrigation or dust control. A precipitate agent is preferable added to the liquid in the third tank to remove heavy metals and the precipitate is periodically backwashed from the filter into the first tank. The sludge created in the settling and filtering process is periodically dewatered in the first tank and mixed with the solid concrete waste sent to the crusher.Type: GrantFiled: May 13, 2008Date of Patent: December 22, 2009Assignee: Concrete Washout Systems, Inc.Inventors: Kevin Mickelson, Roger Engelsgaard
