Abstract: Embodiments of the present disclosure describe filter agitators, filtration units comprising the filter agitators, methods of using the filter agitators, and the like. In certain embodiments, the filter agitators comprise a plurality of first fins extending outwardly from a central vertical axis and arranged in a plane oriented substantially perpendicular to the central vertical axis, wherein the plurality of first fins is configured to promote laminar flow of a fluid flowing in a first direction and induce turbulent flow of a fluid flowing in a second direction; and optionally a plurality of second fins positioned above the plurality of first fins and extending outwardly from the central vertical axis, wherein the plurality of second fins is configured to induce or further induce turbulent flow.

Abstract: Embodiments of the present disclosure describe aquaculture filtration systems comprising a tidal basin, first bead filter unit, second bead filter unit, and optionally an inoculation tank. The tidal basin and first bead filter unit can be in fluid communication. The first bead filter unit can be in fluid communication with the second bead filter unit and optionally the tidal basin via a bypass line. The second bead filter unit can be in fluid communication with the tidal basin and optionally an inoculation tank via an inoculation loop. The aquaculture filtration systems can optionally further comprise pumps for circulating fluids, such as circulation pumps and inoculation pumps, and valves for controlling or directing fluid flow. Embodiments also describe related methods, systems, apparatuses, and the like.
