  • the apparatus comprises a second toilet waste filter having a nanoscale filtration membrane.
  • the apparatus comprises a plurality of filters, to filter liquid win the system at various stages of processing.
  • the filters may be the same type/ construed on or may differ in type and construction.
  • the filters are different based on a membrane size to provide a graduated/ staged filtration function.

  • the purification assembly comprises a vapourisation unit having a heating unit provided at each of the toilet and sink vapourisation tanks to vaporise liquid within said tanks.
  • the purification assembly further comprises a heat exchanger unit having: a heating coil; a liquid circulation tank provided in fluid communication via a conduit manifold to the coil; a circulation pump to drive a fluid circulation through the heating coil and the liquid circulation tank.
  • the syngas combustion chamber is located proximate to the heating unit and/or the apparatus further comprises a heat recovery and transfer arrangement to transfer heat energy from the syngas combustion chamber to the heating unit and/or the dryer.
  • the method comprises processing sink liquid waste using a sink waste processing unit having a sink liquid waste tank and a sink liquid waste filter.
  • human waste processing apparatus comprising: a solid-liquid separator having a separator inlet connectable in fluid communication to a toilet, a predominantly solid matter outlet and a predominantly liquid matter outlet; and optionally a heating unit having a heating unit inlet connectable to the solid matter outlet of the separator.
  • a step of filtering toilet waste liquid via a waste liquid filtration unit comprises: filtering the toilet waste liquid via a first toilet waste filter having a microscale filtration membrane and filtering the toilet waste liquid via a second toilet waste filter having a nanoscale filtration membrane.
  • human waste processing apparatus comprising: a solid-liquid separator connectable in fluid communication to a toilet; a solid waste processing arrangement coupled to an outlet of the separator and having a heating unit with a heating chamber to heat and/or thermally decompose at least the solid waste received from the separator.
  • apparatus to process predominantly solid human waste comprising: a separation unit having an internal chamber with an inlet to receive mixed solid and liquid human waste, a solid waste outlet to output predominantly solid waste from the chamber, a liquid waste outlet to output liquid phase waste and/or gas phase waste from the chamber, a heater to heat the internal chamber and the mixed solid and liquid waste to provide at least distillation of the liquid waste and separation from the predominantly solid waste.
  • the syngas may be processed by mixing with air and then the air syngas mix condensed (condensation of the product syngas constituents with liquid/water vapour).

  • the airtight waste transfer valve may comprise the solid-liquid separator as described herein in which a solid-liquid mixture is delivered into the solid-liquid separator via an input tank and then predominantly solid and predominantly liquid waste may then be output at one or a plurality of output(s).
  • the liquid output of the mechanical solid-liquid separator may comprise a shut off valve at the liquid outlet to prevent onward flow of liquid through this outlet and direct all of the solid and liquid waste exclusively through the solid waste outlet.

  • Toilet wastewater enters the WCT under gravity flow or a pressurised flow from a compact vacuum toilet system. Toilet wastewater liquid flows through the separator 31 under gravity and then under pressure when the LTCT volume reaches a pre-set amount. Separated liquid flows under gravity to the SST and then overflows into the LTCT.

  • the mixer mechanism 181 acts as a gas-air cooler which is collocated with the excess liquid discharge manifold 192, and in particular is located within the discharge manifold 192 that provides the function as a gas-liquid cooler. Accordingly, overflow toilet and sink waste (water) are transferred to the discharge manifold 192 (after purification) that contains the chamber (air-syngas mixer) 181 that receives the syngas output from pyrolizer 164.
  • manifold 192 is configured to receive overflow discharged liquid from the purification utility and in particular overflow where capacity within tank 140 and/or 130 are at a maximum.

Abstract

L'invention concerne un système de traitement liquide-solide et/ou liquide conçu pour le traitement de déchets liquides-solides mélangés et pour le traitement ultérieur de déchets principalement liquides et solides provenant de toilettes, d'éviers et autres, qui est efficace à la fois pour réduire le volume des déchets solides et pour filtrer et épurer les déchets liquides en vue de leur recyclage et/ou de leur utilisation ultérieure. Le présent système et appareil peut être intégré dans des véhicules de transport, notamment des avions, des navires, des trains et des véhicules routiers/terrestres. Le présent système est également adapté et compatible pour l'installation, la mise en œuvre et le fonctionnement sur des sites statiques et des emplacements qui ont un accès limité ou inexistant à un réseau d'égouts à base d'eau.
