  • Publication number: 20180009011
    Abstract: The present invention relates generally to cleaning waste collection systems such as but not limited to sewers, sumps, wet wells, collection tanks, digesters, clarifiers, classifiers, etc. and in particular to cleaning and removal of solid and liquid materials therefrom. In another embodiment, the present invention relates to an improved slurry hose and/or pipe for use in connection with cleaning waste collection systems such as but not limited to sewers, sumps, wet wells, collection tanks, digesters, clarifiers, classifiers, etc. and in particular to cleaning and removal of solid and liquid materials therefrom.

  • Publication number: 20060179603
    Abstract: An apparatus for cleaning waste collection systems of solid materials. The apparatus is capable of cleaning waste systems in two known ways. First, a pumping method uses normal and injected water flow to suspend the solids in a slurry. A submersible pump moves the slurry from a collection point up to a pressurized container where the water content of the slurry is decanted and reused as injection water while the particulate material settles to the bottom of the pressurized container. Second, a vacuum system may be used to move the slurry from the waste system to the waste container. The vacuum system creates a negative pressure differential, causing material to be pulled through a vacuum tube and into the waste container. When the container becomes substantially full of solid particles, it may be emptied at a dumpsite.
