A method of treating a liquid, the method including: receiving a chemically treated liquid; passing the chemically treated liquid through a nanobubble generator to produce a nanobubble-containing liquid; treating the nanobubble-containing liquid with disinfecting radiation to produce a resultant liquid; and releasing the resultant liquid for use. A liquid treatment system including: a source of liquid; a chemical treatment station to test the chemical content of the source liquid and, if necessary, provide an appropriate amount of chemical treatment to the liquid to provide a chemically treated liquid; a nanobubble generator in fluid communication with the chemical treatment station that generates nanobubbles to provide a nanobubble liquid; a radiation-based disinfecting unit (RDU) in fluid communication with the nanobubble generator that exposes the nanobubble liquid to radiation and provides treated liquid; a pump to produce a liquid flow through the system; and an outlet through which the treated liquid flows.

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.

Disclosed are methods, apparatuses and systems for the remediation of contaminated soils, groundwater, water, and/or waste using a combination of reagents. The disclosed methods may be used to treat various recalcitrant halogenated substances, such as perfluoroalkyls and polyfluoroalkyls. Particular combinations of reagents that may be used in the disclosed methods include but are not limited to: (1) persulfate, oxygen and ozone; (2) persulfate, salt, oxygen and ozone; (3) persulfate, phosphate, and/or oxygen; (4) persulfate, phosphate, oxygen and ozone; (5) persulfate, phosphate, salt and oxygen (6) persulfate, phosphate, salt, oxygen and ozone; (7) oxygen and salt; and (8) air and salt. The disclosed methods may include the transfer of contaminants from an aqueous phase to a foam prior to the destruction of the contaminants.

A system and apparatus configured to facilitate on-site treatment of wastewater from a residence is described. The system is configured to immediately treat wastewater as it is generated, on an as-needed basis, and works to remove undissolved down solids and reduce dissolved materials concentrations to a uniform level prior to transmission of the wastewater to municipal waste water treatment facilities and/or any non-drinking application. The system employs a two-stage treatment apparatus where the first stage is configured to pre-grind and decompose undissolved solids of the wastewater and the second to reduce dissolved materials concentrations. The first stage uses turbidity meters, and the second stage uses pH, BOD and conductivity to ensure a uniform output from each stage. A fast decomposer has rotating filters which operational modes ensure that the filters do not become clogged with solids in a cake form simultaneously.

A toilet sub-system of a wastewater management vehicle includes a toilet and a housing. The housing is associated with the toilet and includes a macerator pumping arrangement having a macerator and a pump. The macerator includes a plurality of macerating knives. The pump is an air pump providing positive pressure in a macerator chamber to pump waste from the macerator chamber. The sub-system further includes at least one motor for driving the pumps and the macerator. The macerator pumping arrangement is operative in a macerating mode and a pumping mode, such that in the macerating mode the first motor first drives the macerating knives to macerate the waste and subsequently in the pumping mode the waste is pumped out of the macerating chamber by positive pressure.

An apparatus for delivering wastewater from a recreational vehicle to a drain includes a housing having an outer wall and an inner wall generally perpendicular or slightly angled to the outer wall. The housing and the inner wall define an inlet chamber above the inner wall and a further chamber below the inner wall. The housing further includes an outlet downwardly extending from the inlet chamber.

The invention relates to the mitigation of harmful water-borne bacteria such as cyanobacteria. Multiple apparatus are described. One apparatus can apply at least one of UVC irradiation, microbubbles and ultrasonic sound to mitigate the harmful water-borne bacteria. Methods of mitigation of the harmful bacteria are described that do not involve the application of chemicals.

The present invention addresses the problem of providing a soil amelioration method that makes it possible to conveniently ameliorate soil. This soil amelioration method involves applying nano-bubble water to soil.

Provided is a tank sterilizer composed of a power supply part including an operation switch, and a sterilization part for sterilizing fluid in a tank, wherein a sterilization effect is maximized by generating microbubbles by electrolysis or electric discharge instead of killing bacteria by using a UV LAMP, an ozone lamp, and a pressure pump, and due to the coupling of a bubble generation module and a power connection module to each other by an electroconductive connector, a separate power connector is not required to be installed, whereby the tank sterilizer is simple in structure and is easy to be installed.
