A method of using algae to remove a contaminant or pollutant from a first fluid is provided. The method can include providing a growing apparatus having a first reservoir containing the first fluid and a second reservoir containing a second fluid, and growing the algae using the growing apparatus. The method can further include exposing the algae to the first fluid within the first reservoir where the algae uptakes the contaminant or pollutant from the first fluid, and exposing the algae via a belt to the second fluid in the second reservoir where the algae is stimulated to release the contaminant or pollutant. Exposing the algae to the first fluid within the first reservoir or the second fluid may change a growth rate of the algae.

The present invention relates to the field of water surface treatment, and in particular to a cleaning ship for water surface treatment for harvesting water plants. In order to solve the technical problems that the existing cleaning ship cannot adapt to the waters of different depths for harvesting water plants, and a hull has low load utilization rate for the collected water plants and affects the overall working efficiency and the fuel economy of the hull, the present invention provides a cleaning ship for water surface treatment for harvesting water plants, comprising a steel belt conveying mechanism, a driven shaft and the like. The steel belt conveying mechanism drives the driven shaft to rotate.

A hydroponic system for cultivation and harvesting of floating aquatic plants is provided. The hydroponic system includes an arrangement of a plurality of vertically-stacked cultivation trays, each tray containing an amount of fluent media on which floating aquatic plants are able to grow. The hydroponic system also includes a media reservoir in which fluent media is contained and subject to treatment before being circulated to the cultivation trays and a harvesting reservoir for receiving aquatic plants grown in the cultivation trays and harvested from the same. The hydroponic system further includes an automated control system that manages media flow into and from the trays and aquatic plant harvesting from the trays. A method of cultivating and harvesting floating aquatic plants is also provided.

A robotic system for use within a fluid environment is provided. The robotic system may comprise a robot, a vacuum nozzle, an electromagnetic guide wire, and a control panel. The robotic system functions to aid in the production and/or collection of microbial biomass, plant biomass, debris, waste, suspended solids, suspensions, and other substances that are present in fluid suspensions within aquatic systems, marine environments, reactors, and photobioreactors, as well as submerged or partially submerged spaces.
