A near-zero-discharge recirculating aquaculture system with 3D-printed poly (lactic acid) honeycomb as solid carbon

A novel near-zero-discharge recirculating aquaculture system was successfully set up and ran for six months or above. A uniquely designed and 3D printed poly (lactic acid) (PLA) structure was applied as carbon source. The system achieved over 50 % daily nitrogen removal capability and maintained a l...
