The present invention discloses a small integrated greening device and method for recycling wastewater, including a wastewater collection system, a microorganism and plant purification system, and a reclaimed water collection and distribution system. The method includes the following process: greywater or wastewater is collected through a pipeline and enters a water collection tank of a wastewater collection part. Lifting is performed by submersible sewage pumps, such that the lifted water enters a microorganism and plant synergistic purification and greening part. Each submersible pump is controlled by one corresponding automatic water level controller to transport the treated water to the reclaimed water-use sites. The device and method provided by the present invention utilize the physical and chemical action of a filler and the synergistic purification effect of microorganisms and plants to purify the greywater, and the purified reclaimed water is used for flushing toilets, watering trees or other purposes.

A resource treatment system for urine and feces separation and recovery in urine diversion dehydration toilets, includes a urine-faeces division toilet, a urine and gray water treatment system, and a fermentation and biodegradation fecal system. The urine-faeces division toilet is configured to separate and recover urine and feces discharged by users. The urine and gray water treatment system includes an adjusting pool, a microalgae culture device and a metal-based electrogenerated dynamic membrane. The adjusting pool is configured to receive the urine in the urine-faeces division toilet and domestic sewage, and adjust a urine-to-domestic sewage ratio. The metal-based electrogenerated dynamic membrane includes a metal microfiltration membrane, a stainless-steel mesh and a power supply. The fermentation and biodegradation fecal system includes a collection and adjusting device, a fermentation bed and a biodegradation chamber.

The efficiency of water disinfection can be significantly increased by supplying the ozone in combination with oxygen to an inlet of a cavitation pump or a line atomizer. A compressor can be introduced at an inlet of the cavitation pump or the line atomizer, compressing the gas mixture at a pressure higher than the pressure within pump or the atomizer. The compressed gases are provided to the inlet of the atomizer or the pump, where the compressed gases mix with the water and enter the cavitation pump or the line atomizer (where most of the dissolution of the gases happens). The compressor allows to increase the amount of oxygen and ozone provided to the pump or the line atomizer, increasing their dissolved concentration. In addition to the disinfecting properties, the higher level of oxygen correlates to an improved taste of the water.

A device, system, and processor-readable medium for untreated grey water treatment and reuse are disclosed. Untreated grey water entering a building's plumbing system is tested for recyclability before it routes for treatment and reuse or disposal through a building's sewer line. Certain sensors decide how to route the untreated grey water through treatment in the device. Treatments to untreated grey water could include multi-level filtration and heating/cooling cycles for a prescribed time period to produce treated grey water meeting EPA-approved standards. Once treated, the treated grey water is routed to treated grey water tanks where it is stored for later use in a building's toilets and landscaping.

An above-ground low-energy method of dewatering highly contaminated waste e.g. leachate contaminated with at least a first group of contaminants and PFAS is described. The method comprises the step of removing the PFAS before removing the first group of contaminants. The removal of PFAS is undertaken by actively aerating the contaminated waste comprising PFAS to produce a waste stream comprising a concentration of PFAS and a liquid stream having at least some of the first group of contaminants. The one or more liquid streams are separated from the waste streams so as to dewater the contaminated waste. Optionally, the liquid streams are treated to remove the first group of contaminants.

A bathroom system includes a shower system, a sink system, a gray water tank, a toilet, a first conduit, and a second conduit. The shower system includes a drain ring configured to collect gray water from the shower system. The gray water tank includes an internal filtration system and is configured to filter and store gray water. The gray water tank is configured to introduce a chemical into the gray water and is configured to draw electrical power from a power supply. The first conduit is coupled to the gray water, it connects the shower system and the gray water tank, and it is configured to transfer the gray water from the drain ring to the gray water tank. The second conduit is configured to transfer the gray water from the gray water tank to the toilet to provide water for flushing.

An apparatus (12) for treating water, in particular for removing surfactants from waste water, includes a vessel (14), defining an inlet (16) for receiving waste water containing air bubbles, and an outlet (20) for the exit of water, following treatment. Inside the vessel there is at least one tubular member (50) having a lower open end (52) into which the flow of waste water from the inlet may be directed in use. The tubular member (50) extends from the inlet towards a top of the vessel where an upper exit (54) from the tubular member is defined. In use, most un-aerated water entering the vessel through the inlet can exit the tubular member at the lower open end. Foam formed in the water by the air bubbles may travel up the tubular member to the upper exit, which is preferably located above the water level (60) in the vessel.

A solid waste interceptor for a drain includes a tank for collecting waste water therein, the tank having a waste water inlet and a waste water outlet, a tray housing a strainer basket being slidably mounted within the tank, in the manner of a drawer, to be moved between a closed position in which the strainer basket receives waste water from the waste water inlet, and an open position in which the tray extends from the tank to provide access to the strainer basket to facilitate emptying of collected solid waste therefrom. The tray is provided with a drain outlet for delivering waste water passing through the strainer basket into a sump of the tank, and the drain outlet spigot is adapted to abut a front wall of the tank when the tray is in its open position to delimit the open position of the tray.

An additive sub-system for a wastewater management system of a vehicle including at least one holding tank and a toilet has a controller, at least one additive dispenser and a pump. The at least one additive dispenser is in fluid communication with the at least one holding tank or the toilet. The pump is associated with each additive dispenser of the at least one additive dispensers. Each pump is controlled by the controller to dispense an additive from the at least one additive dispenser to the at least one holding tank or the toilet.
