  • Waste tank for vacuum sewage system
    Patent number: 5538546
    Abstract: A vacuum waste containment system to operate in situations where limited water is available and discharge of liquid and waste is undesirable. The system is powered by an external vacuum source. The vacuum draws the waste into a holding tank through an air water separator. The majority of the liquid and waste is deposited into the tank while the residual water is separated and drained back into the tank before reaching the vacuum source. The system has been designed for low weight to be reliable and require minimum maintenance.
    Type: Grant
    Filed: November 7, 1995
    Date of Patent: July 23, 1996
