摘要： The invention relates to a buffer box of a vacuum drainage system, which vacuum drainage system comprises the buffer box, which buffer box comprises as an outer frame structure side walls, end walls, a top wall and a bottom wall and which buffer box further comprises at least one inlet and an outlet, a vacuum drainage piping, at least one collection branch connected to the vacuum drainage system and to the outlet of the buffer box, wherein each of the collection branches comprises a suction valve, a pump connected to the vacuum drainage piping and configured to create negative pressure in the vacuum drainage piping. The buffer box comprises at least two compartments, which comprise a main compartment and a suction compartment with a suction outlet. Between the main compartment and the suction compartment a baffle is located. The baffle extends from the top wall towards the bottom wall and is located at a distance from the bottom wall such that a baffle opening is formed between the main compartment and the suction compartment. The baffle is configured to prevent the air on top of the liquid in the main compartment to enter the suction compartment.

摘要： Methods and systems for treatment of organic waste by means of hydrothermal carbonization include a mixing tank for receiving organic waste. A first batch of mixed wet waste is fed from the mixing tank to a first thermal reactor to undergo thermal hydrolysis. A second batch of mixed wet waste is fed from the mixing tank to a second thermal reactor to undergo thermal hydrolysis. Bio-char sludge is fed in an alternating manner from the first and second thermal reactors to a bio-char cooler. To save energy, hot and pressurized water from the first thermal reactor is subsequently supplied to the second thermal reactor or from the second thermal reactor to the first thermal reactor in an alternating manner for the respective hydrolysis processes.

摘要： Toilet arrangement, which includes a gravity toilet bowl (1) provided with a water trap (11) and an outlet (12). The arrangement further includes a water valve (5), a flush water tank (4), and a flush valve (6) arranged between the flush water tank (4) and the toilet bowl (1), and an activating means (8) for activating a flushing sequence. In order to allow for the use of a standard gravity toilet bowl in connection with a vacuum sewage system, the toilet arrangement comprises an adapter (13) which is arranged between the gravity toilet bowl (1) and a discharge valve (2) connected to a vacuum sewer piping (3). A control mechanism (7) is connected to the vacuum sewer piping (3), the discharge valve (2), the water valve (5) and the flush valve (6), whereby the control mechanism (7) is arranged to be activated by means of the activating means (8).

摘要： A method and installation for handling medical waste, which is collected in a receptacle, includes a vacuum waste system (V), whereby medical waste is collected in the receptacle, medical waste is discharged from the receptacle into a waste fixture connected to a vacuum waste piping (13) of the vacuum waste system (V). The discharge sequence of the vacuum waste system discharges the medical waste from the waste fixture or the vacuum waste piping (13) of the vacuum waste system (V) to a waste collecting unit (20) of the vacuum waste system.

摘要： Method of controlling a vacuum waste system, which comprises a number of sources of waste (9), vacuum sewer piping (7) including at least a branch pipe (71) and at least a main pipe line (72), a discharge valve (8) having an inlet end connected to a source of waste and an outlet end provided with a given type of connection to the vacuum sewer piping, and a vacuum unit (11) connected to the vacuum sewer piping. Vacuum is generated in the vacuum sewer piping by the vacuum unit and a discharge sequence for discharging waste from the source of waste into the vacuum sewer piping is activated by a discharge sequence activating means (20), whereby the discharge sequence is set for a predetermined time. In order to achieve an optimized control of the vacuum waste system, the predetermined time for a discharge sequence for a source of waste is set according to the given type of connection (711, 712) of the discharge valve to the vacuum sewer piping or according to the location (L1, L2) of the discharge valve with respect to the vacuum sewer piping.
