Containment and facility systems for offshore porous floating bioreactors that contain algae water slurries in saltwater environments. A containment system may include a containment boom system, a containment silt curtain system, a containment marineworks system, or a combination thereof. Facility systems include an offshore porous floating bioreactor in fluid communication with at least an onshore algae harvesting system. Algae cultivation may occur at an onshore algae cultivation system or within a porous floating bioreactor, and algae lipid production occurs within a porous floating bioreactor. The lipid induced algae is received by the onshore algae harvesting system for further processing.

Apparatuses including offshore porous floating bioreactors for containing algae water slurries in a saltwater environment. The porous floating bioreactors include a top portion and a bottom portion. At least a portion of the top portion is composed of a first transparent material and at least a portion of the bottom portion is porous. The offshore porous floating bioreactors may be deployed in a saltwater environment to facilitate one or both of cultivation or lipid induction of an algae water slurry contained therein.

A culture apparatus includes an inner box for housing a culture, an outer box surrounding the inner box, and a first vibration prevention mechanism that is disposed between the inner box and the outer box, and is configured to prevent the inner box from vibrating due to the vibration of the outer box.

Floating ponds for the cultivation of algae are disclosed. The floating ponds consist of a buoyant framework, a liner, a culture, and a mooring system. Submersible floating ponds are disclosed with a buoyant framework built from tubes that may be filled or partially filled with, for example, air, or water, or the surrounding water, or the culture, and thereby the present invention provides a framework in which the buoyancy may be modulated. Use of submerging lines and spools are disclosed to control the orientation and depth of the floating pond during submersion.

A system for producing microalgae in the form of biofilm, including a frame, a motor, at least one support and a web designed to receive the biofilm and in which the frame is configured to support the motor, the motor is configured to impart a rotational movement on at least one support, the at least one support is configured to have a rotational movement about an axis of rotation and to support and impart the rotational movement on the web, and the web is configured to at least partially surround the at least one support, wherein that the support is configured to have a non-negative buoyancy in a liquid.

In one embodiment, an algae cultivation system includes a basin that contains a liquid and a photobioreactor at least partially immersed in the liquid of the basin, the photobioreactor comprising a closed container including multiple panels that together define an interior space in which algae can be cultivated, at least one of the panels being transparent, the photobioreactor further comprising an inflatable float associated with the container that can be filled with a gas to change one or both of the position and orientation of the container within the liquid.

The invention relates to a buoyant photobioreactor arrangement, wherein the photobioreactor arrangement is buoyant on a surface water, and comprises a) a transparent photobioreactor container, b) a floating body that is buoyant on the surface water and c) a holding device arranged at or on the floating body holding the transparent photobioreactor container, the photobioreactor container being able to be lowered into the surface water by means of the holding device.

Provided is a cell suspension culturing apparatus suitable for large-scale culture of cells, the cell culturing apparatus comprising a culture solution aspirator having a double-tube structure comprising an outer tube and an inner tube inserted in a lumen of the outer tube, and a suspension culture vessel, wherein in the culture solution aspirator, the outer tube comprises a filter through which a culture solution is passed, the inner tube comprises a suction port for the culture solution passed through the filter, and an air hole which communicates the lumen of the outer tube with the outside is disposed distally in a direction of insertion of the outer tube into the suspension culture vessel.

An anaerobic digestion device based on self-sustained air flotation includes an anaerobic digestion tank unit, a self-sustained air flotation screening unit and a biogas measurement and collection unit. The self-sustained air flotation screening unit includes an air flotation screening part, a material sedimentation part, a reflux part and a three-phase separation part connected sequentially from bottom to top. A digested material in the anaerobic digestion tank unit is pumped into the air flotation screening part, overflows into the material sedimentation part, and then is raised to the reflux part. Gas passing through the three-phase separation part and gas produced in the anaerobic digestion tank unit enter the biogas measurement and collection unit to be measured and collected.
