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.

Exemplary embodiments relate to a water filter for an aquarium comprising a housing with an interior area configured to house a plurality of filtration cartridges, at least one first clamp and at least one second clamp, and a cover with a lid in operative movable+connection therewith. The cover includes a roughing filter chamber that is in operative fluid connection with the housing interior area and a first connection port that is in operative fluid connection with a water inlet, and a second connection port in operative fluid connection with a water outlet and the housing interior area. The first and second clamps are in operative connection with the housing and are releasably engageable with a rim extending around the cover and the lid. In a disengaged position of the second clamp, the lid is movable between open and closed positions while the cover is maintained in engagement with the housing.

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.

Bottom grading apparatuses for aquaculture systems are disclosed herein. An example system includes a vessel filled with water that receives fish, the vessel having a bottom surface with drain; a plenum in fluid communication with the vessel; a multiway valve in fluid communication with the plenum, a mortality pipe, and a grading pipe; and a mortality container in fluid communication with the mortality pipe and the vessel, wherein the fish can re-enter the vessel through the mortality container and deceased fish remain in the mortality container, wherein when the multiway valve is closed to the mortality pipe, the fish will divert through the grading pipe.

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 circulating water purification system for aquaculture breeding, including a feeding machine, a growing pond, a water purification and separation system, and a recycling device, where the feeding machine for feeding fry to the growing pond is disposed outside the growing pond, the upper part of the growing pond is provided with a water-level safety line, the bottom of the growing pond is conical, and a mesh for filtering solids from liquids are mounted at the bottom of the growing pond; the bottom of the growing pond is connected to the water purification and separation system through a first discharge pipe; the water purification and separation system are provided with a feed pump, and pumps water to the growing pond through the feed pump; and the water purification and separation system are connected to the recycling device.

An insulated passive house, building, or skyscrapers system and method with integrated aquaponics, greenhouse, and mushroom cultivation, includes a glazing on a sun facing side at an angle to maximize winter sunlight, and housing a fish tank; a plant growing area; a mushroom growing area; a shop, apartment or office area; a water wall thermal mass that divides the plant growing area from the mushroom growing and the shop, apartment or office areas, and the fish tank; and a natural air ventilation (NAV) system that provides misted air to the mushroom growing and the shop, apartment or office areas, and the fish tank from O2 generated by the plant growing area, and CO2 generated by the mushroom growing and the shop, apartment or office areas, and the fish tank to the plant growing area.

A pedicure, manicure, and massage spa water treatment system is disclosed. The treatment system provides a container for containing spa treatment water and multiple fish, a spa water treatment container having a first spa water treatment section hydraulically connected to the container and a second spa water treatment section hydraulically connected to both the container and the first spa water treatment section, and a carbon reactor device. The spa treatment water hydraulically and sequentially flows from the container to the first spa water treatment section, to the second spa water treatment section, and subsequently to the container. An inlet of the carbon reactor device is in hydraulic communication with the first spa water treatment section and an outlet of the carbon reactor device being in hydraulic communication with the second spa water treatment section. Only a portion of the filtered spa treatment water contacts the carbon reactor device.

A safety system for a fish-tank siphon is an apparatus used to prevent suction of a fish-tank-cleaning siphon from becoming obstructed by fish, underwater plant life, rocks, or other large tank contaminants. The apparatus is configured to protect the intake by preventing potential obstructions from entering the siphon at all. The apparatus includes a grate, a mating mechanism, and a siphon inlet. The grate acts as a protective filter, preventing large items from entering a connected fish-tank-cleaning siphon. The mating mechanism allows for connection of the present invention to a fish-tank-cleaning siphon. The siphon inlet is a section of the fish-tank-cleaning siphon through which the vacuum is applied in order to remove dirty water and water contaminants. The general configuration of these components allows the apparatus to prevent a fish-tank-cleaning siphon from incidentally collecting fish or other underwater creatures, plant life, pebbles, or other contaminants while vacuum-cleaning a fish tank.

A filtration system structure with a front face such as an operating face, including elements of the user interface of the filtration system is provided. A major part of the front face is concave so that the front face is retracted and thereby protected from being damaged.
