There are described methods and systems for supplying water to an aircraft. A water supply assembly is fluidly coupled to a water storage tank via a supply line. An overflow line is fluidly coupled to the water supply assembly. One or more sensors are configured to determine an amount of water in the water storage tank. One or more processors are communicative with the one or more sensors and configured to: determine a desired amount of water to be contained in the water storage tank; determine from the one or more sensors that an amount of water in the water storage tank corresponds to the desired amount of water; and, in response to determining that the amount of water in the water storage tank corresponds to the desired amount of water, transmit an instruction for causing water being supplied from the water supply assembly to the water storage tank to be diverted to the overflow line.

An electrocoagulation (EC) unit that performs an electrocoagulation process on wastewater or the like. In one embodiment, the EC unit includes a reaction tank formed from a non-conductive material, charge plates within the reaction tank that are spaced at a distance, intermediate plates disposed within the reaction tank between the charge plates, and plate conductors configured to electrically couple the charge plates to a power source. The bottom of the reaction tank tapers toward one or more ports which act as an ingress and egress point for the EC unit.

A system includes a first separator configured to receive waste water, retain a first portion of the waste water, and separate the first portion of the waste water into a first vapor and a first solid material; and a second separator in fluid communication with the first separator, the second separator being configured to receive a second portion of the waste water from the first separator and to separate the second portion of the waste water into a second vapor and a second solid material, the second separator including a first condenser, a heating element, and a first electrocoagulation unit. Related apparatus, systems, techniques and articles are also described.

Methods, systems, and apparatuses for temporarily increasing, on demand, the relative humidity of an area located proximate to a user in environments having lower than ambient relative humidity are provided by integrating a personal humidification circuit into a water delivery circuit to provide a diverted flow of water, and provide a flow of water vapor to a user, and returning the relative humidity-enhanced environment to a predetermined relative humidity by purging the environment.

A system and method for decontaminating a fluid and recovered vapor, particularly processing and recycling water used in an oil zone steam process, utilizing a vaporizer-desalination unit to separate a contaminated water flow into a contaminated disposal flow and a clean water vapor flow. The contaminated water flow is recovered after separation from a combined oil and water flow from an oil well. The clean water vapor flow is preferably passed through a steam generator to produce the steam used in the oil zone steam process. The steam is injected into the oil zone of a designated well and then extracted as the combined oil and water flow. Once primed with sufficient external water, the system and method is designed to operate continuously with minimal replenishment because of the water/vapor/steam cycle.

A system for meat processing may include: a conveyor configured to transport animal carcasses or portions of meat through a meat processing facility; and a spray system configured to spray each of the animal carcasses or portions of meat with aqueous ozone when each of the animal carcasses or portions of meat is transported to the spray system by the conveyor. The system may further include a second spray system configured to spray each of the animal carcasses or portions of meat with lactic acid or citric acid when each of the animal carcasses or portions of meat is transported to the second spray system by the conveyor.

An incinerator system includes an evaporator tank having a fluid inlet, a steam vent, and an evaporation cavity and a heating assembly having a plurality of heating rods mounted on a rod spacing mechanism and disposed in the evaporation cavity of the evaporator tank. The rod spacing mechanism is configured to move the plurality of heating rods within the evaporation cavity. The incinerator system also includes a sensor system having a plurality of sensors positioned to perform one or more sensor measurements in the evaporation cavity and a programmable logic controller communicatively coupled to the sensor system and the heating assembly. The programmable logic controller is configured to instruct the rod spacing mechanism to move at least one of the plurality of heating rods based on the one or more sensor measurements.

A system for treating and/or recycling gray water includes a first receiving tank for gray water, a second receiving tank for treated water and a fluidic treatment circuit between the first and second receiving tanks. The first receiving tank includes an element for oxygenating the water in the first receiving tank and a system adapted to deliver enzymes into the first receiving tank. The fluidic treatment circuit includes a filtration unit, a microfiltration unit including at least one microfilter, a disinfection unit and a membrane ultrafiltration unit.

A filter device may include a tank, a drainage section at a lower most end of the tank, a filter medium above the drainage section and below an upper most end of the tank, and a plurality of sensors provided on the tank. A first sensor may be configured to measure a first height of the filter medium. A second sensor and third sensor may be configured to measure a second height of fluids within the tank. Additionally, air is configured to be pumped through the filter medium during an air scouring cycle. A control system may be operational coupled to the filter device, the control system may be configured to maintain the fluids at the second height at a predetermined distance of one inch above the first height during the air scouring cycle.

A method of sanitizing liquid for use in a medical device, the method comprising the steps of providing a medical device defining a water circuit with a volume of liquid, sensing the temperature of the volume of liquid with a sensor, heating the volume of liquid from an initial temperature to exceed a threshold temperature, maintaining the volume of liquid above the threshold temperature, determining a time-temperature value for the volume of liquid periodically once the threshold temperature has been exceeded, calculating a cumulative time-temperature value and providing an output signal once the cumulative time-temperature value has reached a level indicative of a sanitizing dose. A medical device and a liquid sanitizer are also disclosed.
