Abstract: 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.

Abstract: 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.

Abstract: A wastewater management system 10 includes a black water tank 12 for holding black wastewater and a grey water tank 14 for holding grey wastewater. The system 10 may additionally include a filter 62 for filtering suspended solids from the grey water; a first conduit 64 between the grey water tank 14 and the filter 62; a second conduit 66 between the filter 62 and a toilet 22, and a third conduit 68 between the filter 68 and the black water tank 12, the third conduit 68 associated with a valve 26; and a fourth conduit 69 between the filter 62 and the grey water tank 14, the fourth conduit 69 associated with the valve 26. The system 10 further includes a control sub-system 38 in communication with the valves 26 for controlling valves 26 to deliver filtered grey water to the toilet 22 for flush and to periodically clean the filter 62 of captured solids and deliver the captured solids to the black water tank 12.

Abstract: The invention relates to method and a device for preparing a carbohydrate and/or protein product by subjecting a carbohydrate and/or protein to a heat treatment after a few ingredients have been added.

Abstract: A toilet sub-system of a wastewater management vehicle includes a toilet and a housing. The housing is associated with the toilet and includes a macerator pumping arrangement having a macerator and a pump. The macerator includes a plurality of macerating knives. The pump is an air pump providing positive pressure in a macerator chamber to pump waste from the macerator chamber. The sub-system further includes at least one motor for driving the pumps and the macerator. The macerator pumping arrangement is operative in a macerating mode and a pumping mode, such that in the macerating mode the first motor first drives the macerating knives to macerate the waste and subsequently in the pumping mode the waste is pumped out of the macerating chamber by positive pressure.
