A holding tank for a sanitary installation carrying a sanitary fixture receives fecal matter or wastewater from the sanitary fixture of the sanitary installation and has at least one inlet and at least one outlet. At least one suction float in the holding tank floats on the liquid therein and forms with at least one suction chamber opening downward through a suction screen into the tank. An extraction line connected to at least one suction pump opens into the liquid in the suction chamber for withdrawing the liquid from the holding tank through the suction float and for recycling the extracted water for use as a flushing fluid for the sanitary fixture of the sanitary installation.

The disclosure relates to a portable waste collection and sanitation system designed to handle liquid and solid waste, and while conserving water and minimizing odors. The sanitation system is also designed with modular components adapted for in-home installation, where the system can be quickly disassembled and relocated as needed, such as for moving the components to a new location based on environmental conditions.

A system for collecting and storing urine includes a toilet with a bowl and a tank. The bowl includes a wall dividing the bowl into a first region configured to receive liquid waste and a second region configured to receive solid waste. The system also includes a first line in fluid communication with the first region to transfer the liquid waste from the first region, and a second line in fluid communication with the second region to transfer solid waste from the second region. A storage tank is coupled to the first line such that the storage tank is configured to receive the liquid waste from the first region via the first line.

A side-opening sleeve valve having an inner barrel with a shaped opening through its cylindrical wall having a longer size along the axis of the inner barrel, and a co-annular outer barrel having shaped opening through its cylindrical wall having a longer size along the axis of the outer barrel. The inner barrel is rotatable relative to the outer barrel between a first open position where the shaped openings overlap to form a side opening into the sleeve valve, and a second closed position where the shaped openings do not overlap. The side opening has an effective axial opening size and an effective lateral opening size in a ratio of at least about 2:1. The side-opening valve is useful with water-less toilet that can empty into the side-opening valve when opened, and when closed, a pigging fluid flush system pushes the waste in the side-opening valve to a sewage system.

The invention relates to an installation (5) for treating wastewater from a toilet (3), comprising a solid/liquid separation filter (25) and a liquid recirculation circuit (27) for conveying a liquid from said filter to a tank (11). The installation (5) is characterised in that the filter (25) has an inlet intended to be connected to a bowl, a solid/liquid separation module, a first outlet connected to a discharge pipe (30) and a second outlet connected to the recirculation circuit, said filter (25) conveying the solid materials to said first outlet and the liquid materials to said second outlet, said installation also being characterised in that said recirculation circuit comprises a filtration assembly designed to make said liquid reusable. The invention also relates to a sanitary unit (I) comprising such an installation.
