A waste system is disclosed. In some embodiments, the waste system includes a vacuum cell, a flexible waste container, and a vacuum source. The flexible waste container may have at least one flexible membrane at an interface between the flexible waste container and the vacuum cell. The vacuum source may be configured to suction air out of the vacuum cell to generate a negative pressure in the vacuum cell. The vacuum source discharge is generally odorless as it is separated from the waste. This odorless discharge can enter occupied aircraft compartments. The negative pressure in the vacuum cell acts on the flexible waste container to generate a (second) negative pressure in the flexible waste container. The negative pressure in the flexible waste container acts on an interface between a toilet and the flexible waste container to pull waste from the toilet into the flexible waste container.

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 electromagnet means 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.

A water rinsing system for a toilet includes a fluidic module, a water supply conduit, and a bend connector. The fluidic module is configured to direct water to a toilet bowl. The water supply is configured to supply water to the fluidic module at a rim of the toilet bowl from a water source. The bend connector is configured to connect the fluidic module and the water supply at an angle to overhang the rim of the toilet bowl.

The present invention provides a complete-circulation-type bio-toilet system in which adjustment tanks capable of storing water to be treated are arranged before and after a septic tank, thereby enabling stable provision of the system without stopping the system even when the system is in heavy use. In a bio-toilet system 1 that performs microbial treatment on water to be treated containing filth and circulates the water to be treated as washing water, it is provided with: a raw sewage tank 3 into which the water to be treated containing filth discharged from a toilet 2 is fed; a first adjustment tank 4 that stores water to be treated 31 discharged from the raw sewage tank 3 while performing aerobic treatment thereon by aeration and discharges the stored water to be treated 31 by a pump 43; a septic tank 5 that performs microbial treatment on the water to be treated 31 discharged from the first adjustment tank 4; a second adjustment tank 6 that stores the water to be treated 31 discharged from the septic tank 5 while performing anaerobic treatment thereon and discharges the stored water to be treated 31 by a pump 62; a reaction tank 7 that decomposes organic matter in the water to be treated 31 discharged from the second adjustment tank 6; and a washing tank 8 that stores the water to be treated 31 discharged from the reaction tank 7 for use as washing water for a toilet bowl.

A method and an apparatus for isolating potentially harmful medical substances, such as antibiotics, is disclosed. An aqueous composition, such as blackwater, contains potentially harmful medical substances present in dissolved state in bodily waste. The aqueous composition is temporarily stored in a buffer tank and is then transferred in batches to a vaporization unit comprising one or more vaporization chambers for producing a water-reduced waste material containing said potentially harmful medical substances. The waste material is subjected to a destructive treatment, such as a high-temperature incineration process.

The present subject matter relates to a stackable toilet cabinet comprising a shower unit 101 arranged in the upper portion of said cabinet; a commode unit 102 arranged in a lower portion of said cabinet; and a wash basin 103 arranged in the upper portion of said cabinet alongside the shower unit 101. The shower unit 101 comprising a concealed shower head in a top housing of said cabinet; and a hand shower and a mixer to actuate the shower unit 101. The commode unit 102 further comprising a pull doors 126a, 126b; a commode 144 connected with a back plate 128 arranged on a wheel base 124, the commode 144 being connected with a soil pipe 130 and two or more telescopic rails 129 for enabling the forward movement of the commode unit 102; and a handle 125 to pull the commode 144.
