The invention relates to preventing microplastics from entering the environment. The invention is directed to filtering and compacting microplastics from any effluent, but in particular to filtering and compacting microfibers from the wastewater of washing machines and other appliances. However, the invention may also be applied in any industry where microparticles are generated, e.g. the industrial manufacture of textiles, or in treating roadside runoff, or where microparticles are handled, e.g. in Waste Water Treatment Plants. The invention is a compactor for automatically extracting and compressing microplastics from waste effluent, the compactor comprising; a chamber with an inlet; at least one plate within the chamber moveable between a non-compressing position and a compressing position, and a drive unit for driving the at least one plate; and a discharge outlet arranged to allow the automatic discharge of compressed microplastics.

The system (10) also comprises a sediment filter (28) for filtering off particulate solids from the used water, wherein the sediment filter (28) is arranged between the tank (24) and the water purification apparatus (19).

Apparatus and systems for laundry wastewater treatment are provided. Generally, systems include one or more grinder pumps for receiving raw wastewater from laundry operations, a lint remover in fluid communication with the grinder pumps, a sediment filter in fluid communication with the lint remover, an ozone treatment chamber in fluid communication with the sediment filter, and a carbon filter. Methods can provide for continuous treatment of laundry wastewater that can be reused in laundry operations, or passed to a wastewater stream (such as sewage).

A solid waste interceptor for a drain includes a tank for collecting waste water therein, the tank having a waste water inlet and a waste water outlet, a tray housing a strainer basket being slidably mounted within the tank, in the manner of a drawer, to be moved between a closed position in which the strainer basket receives waste water from the waste water inlet, and an open position in which the tray extends from the tank to provide access to the strainer basket to facilitate emptying of collected solid waste therefrom. The tray is provided with a drain outlet for delivering waste water passing through the strainer basket into a sump of the tank, and the drain outlet spigot is adapted to abut a front wall of the tank when the tray is in its open position to delimit the open position of the tray.

A reactor arrangement for performing, by means of at least one solid reaction member(s), a biological or chemical transformation, or physical or chemical trapping from, or release of agents to, a fluidic media in a continuous process. The arrangement comprises at least one reactor with a cylindrical reaction vessel (11) in which at least one reactor a transformation device (100) has been mounted. The vessel (11) comprises at least one inlet port (30) in the vicinity of its bottom wall (18) and at least one outlet port (40) arranged in the vicinity of its upper end portion. Each inlet port (30) is connected to a fluid supply member (300) configured to be submerged below the fluid surface level in a pool or a pond. The fluid supply member (300) comprises at least one inlet opening (301) configured to continuously supply a fluid from the pool or the pond to the vessel (11). Each outlet port (40) is configured to continuously let out the fluid from the vessel (11) to the pool or the pond via the outlet port (40). Further a method of using the reactor arrangement is provided.

An indoor grey water purification and reuse device, system and method for public buildings is disclosed. The grey water purification and reuse device includes a grey water storage tank, a grey water treatment assembly and a pneumatic reclaimed water tank assembly which are sequentially arranged from top to bottom. The grey water storage tank is used for storing grey water from one floor above collected by a grey water collecting device. The grey water treatment assembly is used for carrying out multistage purification treatment on the grey water in the grey water storage tank. The pneumatic reclaimed water tank assembly is used for disinfecting reclaimed water subjected to multistage purification treatment and supplying water to reclaimed water reuse facilities on the current floor of the building in a constant-pressure mode.

A biofilm mitigation apparatus includes a supply container, a disinfectant generator, a power source, and a delivery tube. The supply container is configured to store one or more materials for a formation of a disinfectant. The disinfectant generator is configured to generate the disinfectant from the one or more materials from the supply container. The power source is configured to provide electrical power to the disinfectant generator. The delivery tube is configured to transport the disinfectant from the disinfectant generator to a biofilm.

A system and method for the microbiological purification of a liquid. The system includes a high-efficiency plate heat exchanger connected to a coil recirculation chamber via a high-efficiency infrared electric liquid-heater. The liquid enters the system at an ambient temperature, the temperature is raised by the heater and maintained in the chamber via recirculation by a pump. An electronic controller redirects the liquid through the exchanger to cool it and supply to a plumbed outlet. In combination, the system can be used to monitor and control various temperatures, pressures, flow rates, and heat exchanges in order to purify the liquid. The method includes steps to produce, install, implement, and use the liquid purification system to eliminate, neutralize, kill, or otherwise exclude/minimize biological organisms and contamination from the liquid.

A filter assembly and method of filtering wastewater from a washing machine. The filter has a framework for supporting a first filter stage and a second filter stage, a connection on a top of the filter assembly for connecting to a wastewater stream, a diffuser positioned to extend into the first filter stage and configured to rotate about a vertical axis of installation within the first filter stage, and a second filter stage below the first filter stage and configured to receive overflow from the first filter stage. The filter assembly does not include a motor or motorized parts and wherein the diffuser is rotatable by way of the force of the wastewater stream fed into the first filter stage to diffuse the wastewater stream and to spray the wastewater onto and through the filter media allowing the filter media to catch debris within the first filter stage.

A point-source wastewater neutralization system for collecting and treating wastewater discharged by a point-source. The system includes a container coupled to the drain of the point-source to receive the untreated liquid. The container supports wastewater neutralization media for treating and neutralizing the wastewater.
