There is described a wastewater separator for separating a flow of wastewater. The wastewater separator generally has: an axis: an inlet chamber defined around the axis and having a wastewater inlet defining a vortex: an outlet chamber defined around the axis below the inlet chamber and having a solid outlet and a liquid outlet: an annular neck between the inlet chamber and the outlet chamber and defining an opening at a bottom of the inlet chamber. the inlet chamber tapering to the annular neck and the outlet chamber inverse-tapering from the annular neck: and an assembly of angularly inclined fins circumferentially distributed around the axis and axially located between the annular neck and the solid outlet. the angularly inclined fins having an upper edge in fluid communication with a lower portion of the annular neck and a lower edge circumferentially spaced apart from the upper edge along the vortex.

A device for the filtration and purification of wastewater, such as grey water, aimed at providing a new clean and safe water source, comprising: a tank for collecting the water to be treated, comprising an inlet or opening for routing the water to be treated and for discharging the water once filtered and purified; a biocarrier container, placed inside the tank, comprising a plurality of biocarriers containing grown microorganisms, which purify the water; an aeration unit configured to supply oxygen inside the tank in order to promote the aerobic metabolism of the microorganisms and to prevent the appearance of bad odors; and a biocarrier for the growth of microorganisms for the filtration and purification of wastewater.

A mixed matrix membrane that includes polyvinylidene fluoride and TiN nanoparticles may be useful solar-driven surface heating membrane distillation. The plasmonic character of the TiN nanoparticles may locally heat the membrane when exposed to sunlight, which increases the distillation flux across the membrane. Said distillation methods may be particularly useful for treating laundry wastewater to collect distilled water with a reduced concentration of chemical oxygen demand, a reduced concentration of total dissolved solids, and a reduce conductivity. The distilled water may be repurposed for a variety of purposes including agricultural irrigation with significant less impact on the aquatic ecosystem compared to the laundry wastewater.

Laundry treatment appliances for use in a typical household include a tub that has an opening to provide access to the interior and at least partially defines a treating chamber into which fabric items such as clothes, towels, or linens can be placed to undergo a washing operation. A system can be provided for recirculating wash liquid through the tub to reduce water consumption. At least one tank or reservoir and a coagulant dosing system can be included for the chemical treatment of wash water as part of the wash liquid recirculation system. The tank can also serve to separate coagulated solids from the wash water.

Appropriately generate or update algorithms for a water circulation management system. In a filter management server having a processor for managing the water circulation management system equipped with various sensors including a treated water sensor and a drainage water sensor, for treating drainage water using one or more filters, the processor acquires, using the various sensors, predetermined information necessary for analysis of each of performance of the filters and status of use by a user of a water utilization unit. The processor generates, by analyzing the predetermined information and based on information from the various sensors, information related to timing of replacement of the one or more filters, and user use information including use status of a water utilization unit by the user and water use information including water pollution degree. The processor executes control to notify the user of the water use information and the user use information.

The present disclosure provides a device, a system, and a method for filtering liquids, in particular for filtering gray water such that it can be reused for multiple purposes. Also provided is an optional step of purifying the liquid with a chemical such that the filtered liquid is also potable.

A system for water distribution includes a core unit arranged to drive distribution of a water flow to one or more water user units; at least two water user units; and a control unit for operation of the system for water distribution. Two water user units have individual identities, and which the two water user units are connected to the control unit to enable for requesting for water of a certain flow and a certain temperature so that the control unit identifies which water user is making the request and then performs an activity based on the request.

A biologically active sorptive media is disclosed for sustainable contaminant removal in, for example, stormwater management systems. This technology addresses the technical problem of hydrophilic trace organic contaminants and dissolved-phase nutrients passing through conventional stormwater infrastructure, posing risks to groundwater and surface water quality. The biologically active sorptive media comprises a biopolymer matrix formed from alginate hydrogel, encapsulating sorbent materials (e.g., powdered activated carbon (PAC), iron-based water treatment residuals (FeWTR]), growth substrates (e.g., wood flour), and biodegrading organisms (e.g., white rot fungi). These beads enable rapid sorption of contaminants during storm events and subsequent biodegradation during inter-storm periods, renewing sorption capacity. The beads are mechanically robust, scalable, and stable for extended periods in high ionic strength solutions. Applications include bioaugmentation of green stormwater infrastructure (GSI), wastewater treatment, and bioremediation. This approach transforms GSI science by coupling sorption and biodegradation for enhanced contaminant removal.

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 modifiations 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.

A mobile water filtration system for use with a mobile firefighter gear cleaner. The mobile water filtration system is self-contained and equipped to condition the water used for washing firefighter gear. The mobile firefighter gear cleaner requires make-up water of a particular quality, and the discharge water becomes contaminated after the process. The instant invention discloses a process using a series of filters for use in decontamination of the wash water, allowing for reuse in the system or for discarding the water without adversely affecting the environment.
