Wastewater leaching chambers and leaching channels are disclosed. The chambers may include a recess for receiving a wastewater supply, the recess serving to lower the overall height of the combined chamber and supply. The recess also configured to tightly seat the supply and form a gap therebetween. Leaching channels having a high aspect ratio may also be coupled to or otherwise in fluid communication with the chamber.

A method for treating wastewater or sludge comprises the steps of adding the wastewater or sludge to a reactor and mixing the wastewater or sludge with a stream to thereby decrease a ratio of alkalinity to ammonium in the reactor, the reactor containing ammonium oxidising bacteria that oxidise ammonium to produce nitrite and decrease pH.

An exemplary power system utilizes turbines configured within a water intake conduit to the desalination processor to produce power for the desalination processor. Water intakes are configured to provide a natural flow of water to the desalination processor though hydrostatic pressure. One or more turbines coupled with the water intake conduits are driven and produce power for the system. The desalination processor incorporates Graphene filters to and may include a structured water system to increase the H3O2 concentration of the water prior to Graphene filters. Discharge water may be pumped back into the body of water but be separated from the intakes. A secondary power source, such as a renewable power source, may be used to produce supplemental power for the system. Power produced may be provided to a secondary outlet, such as a power grid, all above and/or underground.

The present invention describes a liquid recycling system and method for purifying and either recirculating or discarding of liquid. The system includes a liquid input line, a tank, and a circulation pump for providing recirculation of liquid from the tank. A filter and a heater are used to treat liquid from the circulation pump. A valve is provided to direct liquid either to a shower head or faucet, or back to the tank. Additional plumbing and components can be used to provide multiple independent recirculation loops with the tank. An electronic controller can be used to control components of the present invention, where a user could interface with the controller via a control panel or a software application accessed by a portable electronic device.

In one embodiment, a dilute wastewater treatment system includes a separation subsystem configured to receive dilute wastewater and separate it into a product stream containing a low concentration of organic material and a reject stream containing a high concentration of organic material, and a conversion subsystem configured to receive the reject stream from the separation subsystem and anaerobically treat the reject stream to break down the organic material and separate it from water within the reject stream.

The invention relates to a process and apparatus that treats waste water, in particular waste water containing surfactants and including grey water, for local reuse. According to the invention, the process comprises a) collecting waste water in a reservoir; b) injecting gas into waste water from the reservoir to form bubbles in the waste water; c) separating the bubbles, and any entrained contaminants, from the waste water; d) drying the separated bubbles and returning any water recovered from the dried bubbles to the waste water undergoing treatment; e) optionally repeating steps b) to d) to achieve the desired purification of the waste water; and f) collecting the purified waste water. The invention provides a robust process and a mechanically simple apparatus that does not require regular replacement of chemicals or filters, yet is capable of treating waste water locally, and in particular grey water for household reuse.

A system and method includes an aeration subsystem that excites enzymes in the liquid waste passing through the septic system. The aeration subsystem includes a compressor section that compresses the liquid waste. The method includes mixing enzymes into the fluid waste material, compressing the fluid waste material with the compressor, injecting air into the compressed fluid waste material, and determining whether the fluid waste material is at a desired cleanliness, and if not, recirculating the fluid waste material through the compressor.

A sink applied to a system for recovering and reusing graywater includes a sink body, including a water basin located at an upper part of the sink body and a cavity located at a lower part of the sink body. The water basin comprises a water outlet configured to be connected to a sewer. The sink also includes a sink graywater recovery pipeline configured to be connected to the water outlet. The sink also includes a washing device configured to be connected to the sink graywater recovery pipeline. The sink also includes a switching device configured to switch between the sewer and the sink graywater recovery pipeline. When the switching device opens the sewer and closes the sink graywater recovery pipeline, the graywater is led into the sewer and discarded. When the switching device opens the sink graywater recovery pipeline and closes the sewer, the graywater is led into the washing device.

The present disclosure describes systems and methods for wastewater treatment. In some embodiments, a system may include one or more of a pair of electrodes, a first membrane selectively permeable to a first wastewater nutrient, a second membrane selectively permeable to a second wastewater nutrient, and at least one spacing frame comprising a structural element, a gasket, and a flow channel. In some embodiments, the system may further include a septic tank.

The present inventive concept relates to a water recycling device comprising: an outlet configured to output treated water; a drain for collecting used water output from said outlet; a return/evacuation path in liquid communication with said drain, wherein said return/evacuation path comprises an inlet for receiving water collected by said drain; a return path in liquid communication with said return/evacuation path; a treatment path in liquid communication with said return path and said outlet; an external water path in liquid communication with said treatment path, said external water path being connected to an external water outlet; a valve arrangement configured to accept as inputs used water from said return path and/or external water from said external water path, said valve arrangement being placed between said return path and said treatment path, said valve arrangement being configured to direct said inputs to said treatment path, said valve arrangement being configured to mix said external water with said used water from said return path; a circulation pump for providing a flow in said water recycling device; and a water treatment arrangement placed downstream to said valve arrangement.
