Enhancements to the Double Drain technology used for separation of settle-able solid wastes previously developed. Anti-vortex fins are added to the central clarified effluent water manifold to minimize re-suspension of settled solids. A further aspect includes the addition of a slotted horizontal cover plate to a solid waste collection sump below the tank floor. These additions significantly increase the effectiveness of the Double Drain system for separation of settle-able solid waste from fish culture water. The enhanced Double Drain Tank design with the anti-vortex feature could also be used in non-fish culture applications to enhance the separation of settle-able solids from any liquid waste water flow.
