A bioreactor for a water treatment system includes a tank configured to receive an influent liquid, a separator structure positioned in the tank, the separator structure having a frustoconical shape and defining a downwardly-facing opening proximal to or at a bottom of the separator structure, an interior of the separator structure being in communication with the tank, external to the separator structure, at least via the opening, an aeration vent positioned proximal to a bottom of the tank and configured to direct air into the tank, but not directly into the interior of the separator structure, and an effluent outlet communicating with the interior of in the separator structure, proximal to a top of the separator structure, a relatively clean effluent liquid, in comparison to the influent liquid in the tank, exiting from the separator structure via the effluent outlet.

A motor vehicle including a water provision unit for providing water to at least one water consumer. Here, a water collection tank, a primary water tank and at least one secondary water tank are provided. The water collection tank is or can be fluidically connected to a water source and the primary water tank, bypassing the water collection tank and the secondary water tank, is fluidically connected to the at least one water consumer. The water collection tank is fluidically connected both directly and indirectly via the at least one secondary water tank to the primary water tank, and the water provision unit includes a water conveying unit which is provided and designed for conveying the water out of the water collection tank in direction of the primary water tank by a gaseous conveying medium.

Described herein is aerobic granular sludge gravity-driven membrane system, methods of making and using thereof are described. The aerobic granular sludge (AGS) integrated with a gravity-driven membrane (GDM) filtration system is an energy efficient wastewater treatment system that takes advantage of AGS reactor systems integrated with gravity-driven membrane system to reduce membrane fouling and produce microbiologically and chemically safe water. The AGS-GDM system includes at least an AGS reactor tank containing raw wastewater and granular sludge and a membrane tank including one or more gravity-driven membrane(s).

A bioreactor for a water treatment system includes an aerator tank configured to receive an influent liquid, and a clarifier positioned in the aerator tank, the clarifier having a generally conical shape and defining a downwardly-facing opening. An interior of the clarifier is in communication with the aerator tank, external to the clarifier, at least via the downwardly-facing opening, and wherein the clarifier is positioned non-concentrically with the aerator tank. The bioreactor further includes a plurality of aeration vents positioned proximal to a bottom of the tank and configured to direct air into the aerator tank, and an effluent outlet positioned in the clarifier. A relatively clean effluent liquid, in comparison to the influent liquid in the aerator tank, exits from the clarifier via the effluent outlet.

The present invention describes an automated, transportable and energy-efficient with a hybrid power capacity wastewater treatment facility that allows for the disinfection of contaminated sanitation wastewater in order to preserve the environment and provide a greater availability of this resource and its reuse. The facility described in the present invention allows to carry out a process for water treatment in five stages based in equalization, oxidation sedimentation, disinfection and filtration. Moreover, it has a photovoltaic feeding system and a night lighting system that allows the operation of the facility in a hybrid way during the day and the night, as well as a structure that allows its easy transportation. Finally, the facility has an automated system comprised by a control panel that allows to manage and monitor every operational condition of it, that integrates and sends all processed programmable information to a programmable logic controller.

This application relates to a system of treating wastewater wherein an oxygen infusion system is used to supersaturate wastewater before aerobic biological processes, wherein oxygen is transferred to the wastewater free of oxygen bubbles and achieves a reduction in power demand for the aeration process of wastewater.
