A device for generating singlet oxygen is provided. The device has a sensitizer that converts triplet oxygen to single oxygen upon exposure to light. The device is configured to keep the sensitizer from contacting external fluids.

An aquarium has wireless lighting which is configured to turn on a lighting device provided inside the aquarium and vertically move the lighting device in water by a wireless magnetic resonance method. Therefore, a light that can be maintained in a submerged state may be provided, thereby providing better aesthetic effects than existing lights of aquariums. In addition, additional devices such as a filter can be moved in water by using a magnetic field, thereby improving functional effects.

An aquaculture system including an aquaculture tank for holding aquaculture water for culturing an aquatic organism, a thermal insulation house that covers the aquaculture tank, an insulation positioned on at least part of a region surrounding the aquaculture tank, and a temperature adjuster that adjusts a temperature inside the thermal insulation house and/or a temperature of the aquaculture water in the aquaculture tank.

The present invention discloses a recirculating aquaculture system (RAS) and method for shrimp culture through SBR wastewater treatment. The RAS includes a control cabinet, culture tanks, a clean water tank, a clean water filling pipeline, a drainage pipeline, a buried activated sludge tank and a solid-liquid separation mechanism. The solid-liquid separation mechanism comprises a sludge pump, an input pipe, a plate and frame type filter press and a liquid output pipe. An input end of the sludge pump is immersed in sewage of the buried activated sludge tank; and a clean water output end of the plate and frame type filter press is connected with the buried activated sludge tank through the liquid output pipe.

A system for dissolving gases in water comprises a mixing chamber that holds gas and a container in fluid communication with the mixing chamber. In operation, the mixing chamber is flooded to purge the ambient air. A gas delivery system introduces gas into the mixing chamber to push the water out. A pump then pumps temperature and salinity-treated water into the mixing chamber, and a distributor sprays or disperses the water into the mixing chamber. An optional impingement plate and/or mixing medium trap gas bubbles and hold gas-saturated water within the mixing chamber. This produces a volume of substantially bubble-free, highly-saturated gas-infused water that is then released into the container to mix with the water contained therein. This system can be incorporated in aquariums, ice chests, buckets, and live wells found on boats, kayaks, trucks, and other transports.

Apparatus and methods relate to a bi-directional air and water conduit system. In an exemplary embodiment, the conduit system may be provided with an adapter casing. An internal member may be releasably coupled to the adapter casing. A plurality of channels may longitudinally extend through the internal member. The adapter casing, internal member, and plurality of channels may permit fluid to ingress and egress a container. The plurality of channels may be mutually isolated. The adapter casing may be configured to engage with a drain of a cooler. Various embodiments may, for example, advantageously enable supply of fresh water and/or air and evacuation of stagnant water and/or air to facilitate a robust environment for bait in a container.

Methods are proposed to define UE behavior for performing synchronization signal block (SSB) based radio link monitoring (RLM) and channel state information reference signal (CSI-RS) based RLM. In a first novel aspect, if CSI-RS based RLM-RS is not QCLed to any CORESET, then UE determines that CSI-RS RLM configuration is error and does not perform RLM accordingly. In a second novel aspect, SSB for RLM and RLM CSI-RS resources are configured with different numerologies. UE perform SSB based RLM and CSI-RS based RLM based on whether the SSB and CSI-RS resources are TDMed configured by the network. In a third novel aspect, when multiple SMTC configurations are configured to UE, UE determines an SMTC period and whether SMTC and RLM-RS are overlapped for the purpose of RLM evaluation period determination.

A system includes a housing; a water tank positioned within the housing, wherein an inside of the water tank is sealed to prevent contact between material forming the water tank and water within the water tank; a water movement subsystem causing water to circulate within the water tank, including a baffle extending along the center of the water tank dividing the water tank into a circular raceway, and a pump causing water to circulate; an aeration subsystem maintaining an oxygenation level suitable for crustaceans to live within the water tank; a temperature control subsystem maintaining a water temperature suitable for crustaceans to live within the water tank; a water quality monitoring subsystem monitoring a water quality parameter of water within the water tank; a feeding subsystem configured to dispense food into the water tank; a biofloc removal subsystem configured to remove biofloc from the water tank; and a control system.

A cleaning device for ponds (1) for interaction with at least one pond filter for removal of solids (2) from the pond (1) has a sediment swirling device (3) with a pump (11) which sucks in a swirling medium and discharges the latter through at least one ejector channel (4, 5) in the area of sedimented solids (2). The cleaning device is self-floating and is provided with a motion drive (14) and a location determination device for the purpose of directional control.

The present disclosure describes a process for producing a reducing liquid comprising providing a liquid; providing a reducing gas and/or a metasilicate; and infusing the reducing gas and/or the metasilicate to the liquid, for the reducing gas and/or metasilicate to react with the liquid to produce a reducing liquid that has an oxidation reduction potential (ORP) value of about 100 mV or more negative. Further described is the process for preparing a reducing gas, which includes the steps of preparing an activator, introducing the activator into an electrolytic reactor, adding water, and applying a direct current to produce the reducing gas. Also described is a system for producing a reducing liquid.
