In the spatial planning of large seafood restaurants, fresh food supermarkets in commercial complexes and high-end dining clubs, building support columns often become a problem that occupies business area and affects the transparency of the view. In response to this industry pain point, Yijing Aquarium has deeply developed and launched a column-wrapped arc-shaped stainless steel seafood tank for catering and aquaculture. This equipment not only transforms idle building columns into visual focal points, but also provides a high-density and low-loss temporary breeding environment for high-value seafood and aquatic products through a scientific zoned water circulation and constant temperature system.

I. Core Technical Structure and Material Process of the column-wrapped arc-shaped Seafood Tank
A high-quality set of seafood tanks for catering and aquaculture not only needs to have excellent artistic appearance, but also maintain long-term stability in commercial environments with high salinity and high humidity. This seafood tank has achieved several key breakthroughs in engineering design:
1. 304 stainless steel corrosion-resistant frame and champagne gold decorated cabinet body
The base support structure is made of high-strength 304 stainless steel and processed by laser cutting and precise arc bending techniques, perfectly fitting the cylindrical contour of the building. The outer surface of the base cabinet has undergone anti-fingerprint and electroplating passivation treatment. By default, it offers multiple metallic textures such as champagne gold, titanium gold and matte black, which can not only perfectly resist the chemical corrosion of seawater and salt spray, but also blend into the decoration styles of various high-end dining Spaces.
2. Curved surface ultra-clear glass and high transparency visual experience
The viewing window is made of industrial-grade curved heat-bent ultra-clear glass, with a light transmittance of over 91.5%. Compared with the traditional flat glass splicing, the arc-shaped seamless window provides a 270-degree panoramic display effect without blind spots, significantly enhancing the dynamic visual impact of the live seafood in the tank and effectively stimulating consumers' desire to order.
3. The inner wall of the anti-seepage Mosaic is separated from multiple water body partitions
The inner wall of the tank is covered with special anti-seepage blue and white Mosaic tiles, which have excellent scratch resistance and are easy to clean. They are less likely to breed algae and mucus even after long-term use. The interior of the tank can be equipped with transparent acrylic partitions as needed to divide the circular water body into multiple independent temporary breeding areas, enabling the co-breeding of fish, shrimp, crabs, shellfish and other aquatic products with different habits in separate zones.

Ii. Specification Parameters and Engineering Customization Options
Yijing Aquarium offers a full-process customized service ranging from on-site survey and scheme design to factory production and on-site assembly. Customers can flexibly choose the matching items according to the actual size of the building columns and the breeding needs

Inner wall decoration	Blue/white ceramic Mosaic tiles	Brighten the color tone of water bodies, enhance the texture of the ocean, and be resistant to scrubbing and acid and alkali corrosion
Temperature control system	Commercial industrial-grade integrated heating and cooling chiller	The temperature control accuracy reaches ±0.5℃, meeting the requirements of deep-sea cold-water fish and tropical shrimp and crab
Filtration system	Physical dry-wet separation + biochemical nitrification filtration + protein separator	Rapidly degrade ammonia nitrogen and nitrite to keep water clear and clean for a long time

Iii. Practical Tips on Water Quality Control and Operation and Maintenance in the Temporary Breeding System for Fresh Food in the Catering Industry
To ensure the survival rate of aquatic products in the column-wrapped arc-shaped stainless steel catering and aquaculture seafood tank, in addition to a solid hardware structure, scientific water quality maintenance is equally crucial
1. Independent circulation and efficient dissolved oxygen design
The equipment has a hidden storage inside for high-flow commercial water pumps and aeration and oxygenation pumps. To address the issue of dead corners in circular water bodies, a multi-point convective water inlet and outlet layout is adopted to ensure that there are no dead corners in the water circulation of each zone. The dissolved oxygen in the water is maintained at above 6-8 mg/L for a long time, significantly reducing the stress mortality rate under high-density temporary rearing.
2. Protein separation and nitrification system establishment
A large amount of excrement and mucus are produced during the temporary rearing of seafood. Through the built-in high-efficiency protein separator, the protein can be discharged from the water body in the form of foam before decomposition. In combination with the porous ceramic rings and nitrifying bacteria in the biochemical filtration tank, it can quickly convert harmful ammonia nitrogen into low-toxicity nitrate, extend the water change cycle and save water costs.

Iv. Typical Application Scenarios and Engineering Implementation Cases
As a seafood tank for catering and breeding that combines visual aesthetics and commercial functions, this product has been widely applied in the following high-end commercial fields:
· Seafood Restaurant and theme Restaurant: Placed in the central building column of the hall, the traditional blind spot is transformed into a highly attractive seafood stall ordering area.
· Fresh food supermarket in commercial complex: By using the columns in the atrium for centralized display of aquatic products, the overall shopping environment's sense of class is significantly enhanced.
· Lobbies of star-rated hotels and conference halls: Combined with specific aquarium landscapes, they serve as large-scale commercial soft decoration water features, highlighting the company's strength and spatial design sense.
