A grey water tank for vehicles. The grey water tank includes a tank housing having an interior for holding grey water, a filter wall inside the tank housing, an inner tank chamber provided inside the filter wall and an outer tank chamber being provided between the filter wall and the tank housing side wall. A fill level sensor is provided for detecting a fill level of the tank housing. A connection is provided on the tank housing cover in the region of the inner tank chamber for a grey water inlet from a washing device. A connection is provided on the tank housing for a grey water transfer line to a toilet requiring flushing liquid. In order to empty and clean the grey water tank, a connection for a waste water line for discharging the grey water present in the tank housing by a vacuum discharge system is also provided.

WASHING MACHINE AND CONTROL METHOD THEREFOR

A washing machine includes: a water holding barrel; a circulation filtration pipeline, of which a water inlet end and a water outlet end of the circulation filtration pipeline are respectively connected with the water holding barrel; a filter device, arranged in the circulation filtration pipeline, and having a water inlet, a filtered water outlet and a sewage outlet; a sewage pipeline, being used for receiving sewage discharged from the sewage outlet; a control valve assembly, arranged between the water inlet end of the circulation filtration pipeline and the filter device. The control valve assembly includes a first valve chamber and a second valve chamber that are independent from each other, and the first valve chamber communicates with the water holding barrel and the water inlet of the filter device, and the second valve chamber communicates with the sewage pipeline and the sewage outlet of the filter device.

UVC-ASSISTED WASHING APPARATUS AND METHOD

The present invention relates to a washing method and household appliance for textiles in a household appliance, which offers the benefit of disinfection of clothing, the washing liquid, as well as the components of the washing machine that are in contact with the washing liquid and loading clothes through the use of UV-C radiation. Disinfection can be carried out during the washing and/or rinsing step through a predetermined sequence of turning on and off the radiation source. In addition to disinfection without the need to add temperature to the water at the inlet of the washing machine or inside it, there are the benefits of greater cleaning and less damage to clothing, shorter washing time, lower energy consumption, and avoiding the use of disinfectant additives for more ecological wash cycles.

Auxiliary gray water source device for commercial kitchens

An auxiliary gray water supply device captures used wash water from a commercial warewashing machine for supply to a pre-rinse station without substantial modification of the commercial warewashing machine. The captured wash water and treatment agent are delivered to a pre-rinse station for pre-rinsing of dishes that will be washed within the commercial warewashing machine.

12391729 · 2025-08-19 · ·

Fusion proteins containing a targeting sequence, an exosporium protein, or an exosporium protein fragment that targets the fusion protein to the exosporium of a Bacillus cereus family member are provided. Recombinant Bacillus cereus family members expressing such fusion proteins are also provided. Genetically inactivated Bacillus cereus family members and recombinant Bacillus cereus family members that overexpress exosporium proteins are also provided. Seeds coated with the recombinant Bacillus cereus family members and methods for using the recombinant Bacillus cereus family members (e.g., for stimulating plant growth) are also provided. Various modifications of the recombinant Bacillus cereus family members that express the fusion proteins are further provided. Fusion proteins comprising a spore coat protein and a protein or peptide of interest, recombinant bacteria that express such fusion proteins, seeds coated with such recombinant bacteria, and methods for using such recombinant bacteria (e.g., for stimulating plant growth) are also provided.

Systems and methods for point of use water modification

A water use management system may be installed in a setting that contains a primary infrastructure for water use to provide an alternate, modular infrastructure for water use. Fresh water used at various points of use, such as a shower or sink, may be modified by a point of use water conditioner. Water may be modified at the point of use based upon pre-configured routines or manual user selections. Treatments performed on the water may include quality treatments, such as modifying the pH or mineral content, and may also include experience treatments, such as the addition of scents, colors, carbonation, or health and beauty supplements. Additives used during treatment are provided in cartridges that may be inserted and removed from the water conditioner. Cartridges may self-identify when inserted, to aid in compatibility and usability determinations and recycling/recertification processes.

System for water quality measurement and a recirculation system comprising the same

The present invention refers to a system 1 intended for measuring water quality in a system having the capability of recirculating water and flowing water to waste, depending on water quality, said system 1 being a module system comprising a water channel base unit 2, a sensor module unit 3 for water quality measurement and a water distribution module unit 4 for distribution of water to recirculation, wherein the water distribution module unit 4 are attachable to and detachable from the water channel base unit 2.

MODULATING CROSS FLOW FILTERING SYSTEM

According to some embodiments, a system and method of collecting contaminants from contaminated water is disclosed. The system comprises a filter housing and the filter housing includes (i) a filter membrane, (ii) a filtrate port and (iii) a cross-flow port. A modulating valve is coupled to the cross-flow port. A cross-flow line is coupled to the modulating valve. The modulating valve is opened based on a desired effluent flow rate of effluent through the filtrate port.

Apparatus for water filtration, ozone, and ultraviolet disinfection
12459845 · 2025-11-04 · ·

A filtration system that includes a coarse filter, a fine filter, and a pump. The coarse filter filters out sediment from water passing through the coarse filter. The fine filter filters out foreign material larger than a selected pore size. The pump pumps water when a DC voltage is applied to the fluid pump. The pump is in-line with and coupled to the coarse filter and the fine filter such that water is drawn into or pushed into the coarse filter and/or the fine filter. The filtration system includes inlet and outlet connectors, the inlet connector directly coupled to the coarse filter to receive water into the coarse filter and the outlet connector directly coupled to the fine filter to output filtered water received from the fine filter. A power source is coupled to the fluid pump and outputs the DC voltage applied to the fluid pump.
