An additive sub-system for a wastewater management system of a vehicle including at least one holding tank and a toilet has a controller, at least one additive dispenser and a pump. The at least one additive dispenser is in fluid communication with the at least one holding tank or the toilet. The pump is associated with each additive dispenser of the at least one additive dispensers. Each pump is controlled by the controller to dispense an additive from the at least one additive dispenser to the at least one holding tank or the toilet.

An apparatus for delivering wastewater from a recreational vehicle to a drain includes a housing having an outer wall and an inner wall generally perpendicular or slightly angled to the outer wall. The housing and the inner wall define an inlet chamber above the inner wall and a further chamber below the inner wall. The housing further includes an outlet downwardly extending from the inlet chamber.

A stand-alone toilet system is powered by photovoltaic cells to operate a dehumidifier from which water is extracted from the atmosphere by dehumidification and used for flushing; an electronic compressor is situated in the toilet tank to compress air which is used with water in the flush cycle; a motorized or hydraulic hinge is utilized to open and close a toilet cover automatically which can be locked in place by an electromagnet securing mechanism to create an airtight seal in the closed position; a heating element and a UV lamp are situated inside the treatment facility of the toilet system to evaporate liquid and sanitize waste content therein respectively.

The invention relates to a mobile sanitary device, comprising a bowl having an upper opening, a water storage tank which is connected to the bowl via a water conduit that supplies water from the water storage tank to the bowl, a wastewater tank which is connected to the bowl via a wastewater line that discharges the wastewater out of the bowl from a bowl outlet opening to the wastewater tank, a first intermediate tank which is inserted into the water conduit between the water storage tank and the bowl or into the wastewater line between the bowl outlet opening and the wastewater tank. According to the invention, a first sensor for detecting a measured value characterizing a status in the first intermediate tank is arranged on the first intermediate tank, and an electronic monitoring unit is provided which is in signal communication with the first sensor and comprises an electronic memory unit in which process data are stored which represent at least one setpoint value of an operational process of supplying water from the water storage tank to the bowl and of water discharge out of the bowl to the wastewater tank. The electronic monitoring unit also comprises an electronic comparator unit which is configured to compare the measured value from the first sensor with the setpoint value of the operational process and to output an error message if the measured value differs from the setpoint value.

In a first aspect, the present application relates to a method for the treatment of black water, comprising the steps of: collecting black water; treating said black water in an electrocoagulation cell with iron or aluminum electrode, such that electrocoagulation effluent and electrocoagulation sludge are obtained; separating the electrocoagulation sludge from the electrocoagulation effluent; disinfecting said electrocoagulation effluent in an electro-oxidation cell with a titanium or stainless-steel electrode, obtaining disinfected effluent. In a further aspect, the current application relates to a closed toilet system.

A vehicle, in particular a rail vehicle, includes a compressed-air-operated toilet device and a compressed air supply system which supplies compressed air to the toilet device during normal operation. The vehicle also includes an emergency compressed air source that is suitable for providing compressed air for continued operation of the toilet device in the event of a failure of the compressed air supply system.
