A floating fish production system for placement within a body of water and being structured and disposed for containing fish and other aquatic animal, plant and algal species, the system including at least one primary containment tank having an arrangement of individual solid wall sections and an arrangement of individual solid floor sections. Flexible membranes span between and connect to adjacently positioned solid wall and floor sections to define flexible connecting joints that allow the individual solid wall and floor sections to move relative to one another in an articulating action. The flexible membranes allow the tank configuration to temporarily deform from a relaxed state in response to externally applied forces exerted on the tank (e.g., waves, wind, current) to thereby absorb the externally applied forces and reduce stress on the structural integrity on the tank. An air lift system including a high volume, low pressure blower and a spaced arrangement of vertically extending air lift pipes delivers water and oxygen from the exterior body of water and into the tank interior. A flexible main drain in a central area at the bottom of the tank connects to a waste recovery system for removing waste produced by the fish and other aquatic species.

The invention relates to a wall liquid film and wall-free liquid film alternate structured filler adapting to a viscous absorbent. The wall liquid film and wall-free liquid film alternate structured filler is a perpendicular plate structured filler comprising alternate wall-attached films and free films. The wall liquid film and wall-free liquid film alternate structured filler mainly comprises a liquid collection-primary distribution member, a liquid uniform-distribution member, structured solid wall surfaces and holes having a plurality of shapes, and is characterized in that when sprayed liquid flows downward and flows through the wall liquid film and wall-free liquid film alternate structured filler, the liquid enters into the liquid collection-primary distribution member and is subjected to primary distribution and then enters into the liquid uniform-distribution member and is subjected to film-type uniform distribution; and the falling liquid film enters into channels formed from the alternate structured solid wall surfaces and the holes and contacts with gas concurrent flows or gas countercurrent flows. The channels for liquid flowing are regular so that a viscous liquid can smoothly pass through the channels and does not produce foam, emulsification and blocking and thus adaptability to processing liquid viscosity is greatly improved. Through special flow behaviors of the free film and interaction of the free film with the wall-attached film, high-viscosity absorbent mass transfer performances are improved obviously.

A method of manufacturing an integral one-piece solar collector panel by a rotational moulding process is disclosed. The solar collector panel has a plurality of fluid ways extending between opposed ends and transverse headers opening into the open ends of the fluid ways. The panel is moulded by a rotational moulding process using mould faces with a non planar topography, eg in the form of a plurality of lines projecting outwardly proud of the remainder of the mould plate. This enables areas of the moulded body to be formed that are not hollow and form a solid wall in the moulded panel and other areas of the body to be formed that are hollow and form the fluid ways and headers.

This post moulding treatment step is not used in standard rotational moulding processes. The manufacturing process of the invention enables collector panels to be produced at substantially less cost than known prior art methods of making collector panels.
