Abstract
A large bore mobile vacuum system is used with special large bore vacuum adapters to enable a method and system for cleaning ground tanks used to store wastewater. The ground tank cleaning method and system may be safer and more efficient that conventional methods by enabling a human operator to physically remain outside of the ground tank, while preventing the contents of the ground tank from being exposed to the environment during the ground tank cleaning.
Claims12
A method for cleaning ground tanks used for wastewater storage, the method comprising:
- positioning a large bore mobile vacuum system in proximity to a ground tank indicated for cleaning, the large bore mobile vacuum system including a vacuum line having a diameter of at least 8 inches;
- attaching a large bore vacuum nozzle to the vacuum line;
- connecting a pressurized liquid line to a conduit attached to an outer surface of the large bore vacuum nozzle;
- guiding the large bore vacuum nozzle through a tank wall of the ground tank into the ground tank, wherein the vacuum line is physically manipulated by an operator located outside of the ground tank;
- and
- using the large bore vacuum nozzle to clean within the ground tank, wherein at least one of liquid material and solid material is removed from within the ground tank using the vacuum line, including controlling a volume of discharge of the pressurized liquid line from a spray jet in fluid communication with the conduit, wherein the spray jet is directed by the large bore vacuum nozzle when the large bore vacuum nozzle is used to clean the ground tank.
