Intensive aquaculture activities require large quantities of clean water to function well. Microalgae found in the green waters take in nutrients such as ammonia, nitrite and nitrate from the water during photosynthesis thereby depriving the undesired vegetation of the nutrients to grow. This technology relates to an algae-based modular filter for used aquaculture water which incorporates microalgae as a phytoremediation agent to remove contaminants from aquaculture green waters. The microalgae are encapsulated in porous polymer beads to ensure maximum effectiveness and ease of use. Compared to conventional treatment systems, the algae-based green water filter combines water treatment with the generation of fish feed supplements.
By removing the soluble nutrients, the technology can help prevent unsightly algae growth and maintain the aesthetic outlook of open waters.
