Abstract:
A waste handling assembly includes a hose with an inlet for accepting waste. A plurality of pretreatment tablets are located within the hose and are removeably attached to the hose.
Abstract:
The invention relates to a method of remi-neralization and correction of pH for water produced by a fuel cell (P) on board an aircraft, noteworthy in that it consists in diverting part of the water (E1) produced by the cell to at least one treatment tank (200) containing a saturation reagent and in mixing the flow of treated water (E2) issuing from the treatment tank (200) with the undiverted flow of water (E3) so as to obtain water (E5) with the desired mineralization and/or pH. The invention also relates to devices making it possible to implement said method.
Abstract:
Disclosed is a dewatering system and method for separating oil/water sludge into clean water and dewatered waste oil components in a repetitive batch process. The system comprises a vacuum distillation device. The vacuum distillation device has a feed port for loading the oil/water mixture, a processing chamber with heating and heating controlling means, a vapor phase port communicating with the chamber, a vacuum pump connected to the vapor phase port and configured to removing water vapor from the chamber to reduce vapor phase pressure to below atmospheric pressure, and a waste port configured for retrieving dewatered waste oil from a bottom portion of the chamber. The system further comprises a control unit configured to perform one or more control functions for controlling operation of the system in a programmed manner. A gravitational settling device is provided for pre-treating sludge to remove continuous phase water prior to loading the distillation device.
Abstract:
The invention described herein contains two aspects, usable together or separately, that address the needs in the art described above, namely a first aspect that relates to the provision of a transportable water purification system that can be contained on a passenger transport vehicle, and that can use, but does not require, continuous, real-time monitoring, and a second aspect that relates to the use of UV purification of the water as it is uploaded to the passenger transport vehicle after a single pass through the UV chamber.
Abstract:
An apparatus for filtering water has an interface and a filtration/purification canister removably mountable thereon. Connecting the canister to the interface automatically opens a check valve in the interface to permit water to flow from the interface into and through the canister, and then back to and through the interface to an outlet port. Disconnecting the canister from the interface automatically closes the check valve, stopping the flow of water. An end cap may be substituted for the canister to permit fluid to flow through the interface when the canister is not mounted on the interface. The outlet port may be directly connected to an appliance that uses water, to eliminate possible contamination that may occur when water is brought indirectly form the outlet port to the appliance instead. A flapper valve is provided in the canister to prevent back flow of fluid from the inlet port of the canister when the canister is not mounted on the interface. The flapper valve also is provided with an actuating means to automatically open the flapper valve when the canister is mounted on the interface, which permits fluid to be drained from the canister when the fluid distribution system is being drained without disconnecting the canister from the interface.
Abstract:
A pipe treatment system for a supply unit is provided. The pipe treatment system comprises a fresh water inlet pipe, a tap for fresh water, a controllable tap valve, and a control device for the pipe treatment control system. The controllable tap valve is arranged between the fresh water inlet pipe and the tap for fresh water. The control device for the pipe treatment control system is connected to the controllable tap valve so as to place the controllable tap valve in a pipe treatment state when there is a pipe treatment signal at the control device, so as to provide a more reliable pipe treatment system, for example for disinfection or descaling.
Abstract:
Embodiments of the present invention provide a filtration system that can be used to filter debris-laden water and to systems for cleaning the filtration system using a vacuum flush system to create a backwash flow through the filter of the filtration system. The filtration system described finds particular use on-board passenger transport vehicles that have a vacuum waste system, such as aircraft. The filtration system provides the ability to collect, treat, and reuse liquid resources in an environment with a vacuum waste system.
Abstract:
A potable water system (10) comprises a supply line (18) and a water-purification device (20) incorporated thereinto. The water-purification device (20) comprises a microorganism filter (40) having a housing (42) and replaceable cartridge (42). The cartridge's filter media (50) includes a microorganism-capturing membrane (e.g., comprising an electropositive material) and a microorganism-killing membrane (e.g., comprising a biocidal material).
Abstract:
The invention presents a urea bio-electrochemical (UBE) system to achieve resource recovery from water recycling systems. A GAC-urease bioreactor was used to recover urea from wastewater stream, and converted to ammonia. Then, the ammonia produced was used to feed an electrochemical cell to gather electrical energy. The invention shows the feasibility of using the UBE system in combination with a forward osmosis subsystem for water reclamation.
Abstract:
Embodiments of the present invention provide a system to direct water flow through a lavatory and to cleanse grey water through a series of treatment steps. The water may then be re-directed to the faucet for re-use in hand washing or other potable water use or to the toilet for flush water. The treatment steps are altered, depending upon the ultimate use of the water, as flush water need not be treated to the same level as potable water. The system may also function via a cascade of logic commands given by a series of electronic controllers, valves, and sensors which are fine-tuned to supply enough water to each component of the system.
